本發明實施例關於但不限於電腦圖形學領域，特別是關於一種動畫遷移方法和設備、電腦可讀儲存介質。The embodiments of the present invention relate to but are not limited to the field of computer graphics, and in particular relate to an animation migration method and device, and a computer-readable storage medium.

從一個現有的骨骼模型向一個新的骨骼模型遷移動畫，使得現有的骨骼模型所具有的動畫在新的骨骼模型上以自然合理的方式呈現，是電腦圖形學中的一個很有實用價值的技術。但是，相關技術的動畫遷移方案中，現有的具備動畫資料的骨骼模型向新的骨骼模型遷移動畫時適用性較低。Migrate animation from an existing skeleton model to a new skeleton model, so that the animation of the existing skeleton model can be presented in a natural and reasonable way on the new skeleton model, which is a very practical technology in computer graphics . However, in the animation migration scheme of the related art, the applicability is low when the animation is transferred from the existing skeleton model with animation data to the new skeleton model.

本發明實施例至少提供一種動畫遷移方法和設備、電腦可讀儲存介質。Embodiments of the present invention at least provide an animation migration method and device, and a computer-readable storage medium.

本發明實施例提供了一種動畫遷移方法，包括：獲取初始源骨骼、初始目標骨骼以及初始源骨骼和初始目標骨骼之間的節點映射關係；基於節點映射關係更新初始源骨骼和初始目標骨骼中至少一者的節點拓撲結構，得到最終源骨骼和最終目標骨骼，其中，最終目標骨骼中的目標節點均能夠映射於最終源骨骼中的源節點；將與初始源骨骼相關的第一動畫驅動資料遷移至最終目標骨骼上，得到最終目標骨骼的第二動畫驅動資料。An embodiment of the present invention provides an animation migration method, including: obtaining the initial source bone, the initial target bone, and the node mapping relationship between the initial source bone and the initial target bone; updating at least one of the initial source bone and the initial target bone based on the node mapping relationship The node topology structure of the first one can obtain the final source bone and the final target bone, wherein, the target nodes in the final target bone can all be mapped to the source nodes in the final source bone; the first animation driving data related to the initial source bone is migrated Go to the final target bone to get the second animation driving data of the final target bone.

因此，通過依據初始源骨骼和初始目標骨骼之間的節點映射關係更新初始源骨骼和/或初始目標骨骼的拓撲結構，使得最終目標骨骼的目標節點均能夠映射於最終源骨骼中的源節點，以便將與初始源骨骼相關的第一動畫驅動資料遷移到最終目標骨骼上，從而驅動最終目標骨骼運動，故實現了不同骨骼之間的動畫遷移，而且無需要求待遷移的源骨骼和目標骨骼之間的初始拓撲結構完全一致，從而提高了骨骼之間的動畫遷移的適用性。Therefore, by updating the topology structure of the initial source bone and/or the initial target bone according to the node mapping relationship between the initial source bone and the initial target bone, the target nodes of the final target bone can be mapped to the source nodes in the final source bone, In order to migrate the first animation driving data related to the initial source bone to the final target bone, thereby driving the movement of the final target bone, so the animation migration between different bones is realized, and there is no need to require the source bone to be migrated and the target bone The initial topology between bones is completely consistent, which improves the applicability of animation migration between bones.

在一些實施例中，最終目標骨骼與最終源骨骼的節點拓撲結構一致，和/或，最終目標骨骼與最終源骨骼之間的節點一一映射。In some embodiments, the node topology of the final target bone is consistent with that of the final source bone, and/or, the node-to-node mapping between the final target bone and the final source bone.

因此，通過保障最終目標骨骼中的節點在最終源骨骼中具有對應的節點與之映射，且映射關係為一一映射，不存在一個目標節點對應多個源節點的情況，使得後續最終目標骨骼中的節點上均有對應動畫驅動資料，且每個節點上的動畫驅動資料的數量為1，不存在一個節點有多個動畫驅動的情況，從而使得最終目標骨骼的動畫驅動更自然。Therefore, by ensuring that the nodes in the final target bone have corresponding nodes mapped to them in the final source bone, and the mapping relationship is one-to-one mapping, there is no situation where one target node corresponds to multiple source nodes, so that the subsequent final target bone There are corresponding animation driving data on each node, and the number of animation driving data on each node is 1. There is no case that a node has multiple animation drivers, so that the animation driving of the final target bone is more natural.

在一些實施例中，節點映射關係包括初始源骨骼和初始目標骨骼中的節點之間的映射關係；基於節點對應關係更新初始源骨骼和初始目標骨骼中至少一者的節點拓撲結構，得到最終源骨骼和最終目標骨骼，包括以下至少之一：在兩個骨骼之間存在多個節點映射於同一節點的情況下，更新其中一個骨骼的節點拓撲結構；在骨骼中存在未有映射關係的情況下，更新未有映射關係的節點所在骨骼的節點拓撲結構；其中，兩個骨骼包括初始源骨骼和初始目標骨骼，經更新之後的兩個骨骼之間的節點一一映射。In some embodiments, the node mapping relationship includes the mapping relationship between the nodes in the initial source bone and the initial target bone; based on the node correspondence, the node topology of at least one of the initial source bone and the initial target bone is updated to obtain the final source The bone and the final target bone, including at least one of the following: when there are multiple nodes mapped to the same node between the two bones, update the node topology of one of the bones; if there is no mapping relationship in the bone , update the node topology structure of the bone where the node with no mapping relationship is located; wherein, the two bones include the initial source bone and the initial target bone, and the updated nodes between the two bones are mapped one by one.

因此，通過更新骨骼的節點拓撲結構能夠使得兩個骨骼之間的多個節點映射於同一節點的情況調整為兩個骨骼之間的節點一一映射，以減少後續動畫驅動最終目標骨骼的過程中出現不合理的情況出現。Therefore, by updating the node topology of the bone, the situation where multiple nodes between two bones are mapped to the same node can be adjusted to a node-to-one mapping between the two bones, so as to reduce the process of subsequent animation driving the final target bone Unreasonable situations arise.

在一些實施例中，更新未有映射關係的節點所在骨骼的節點拓撲結構，包括：將未有映射關係的節點合併至具有映射關係的相鄰節點，其中，相鄰節點為未有映射關係的節點在所在骨骼中的父節點或子節點；和/或，更新其中一個骨骼的節點拓撲結構，包括：在多個節點位於同一骨骼分支的情況下，更新多個節點所在的第一骨骼；在多個節點位於不同骨骼分支的情況下，更新不包含多個節點的第二骨骼；其中，第一骨骼和第二骨骼中的其中一個為初始源骨骼，另一個為初始目標骨骼。In some embodiments, updating the node topology of the bone where the node without a mapping relationship is located includes: merging the node without a mapping relationship into an adjacent node with a mapping relationship, wherein the adjacent node is a node without a mapping relationship The parent node or child node of the node in the bone where it is located; and/or, updating the node topology of one of the bones, including: when multiple nodes are located in the same bone branch, updating the first bone where multiple nodes are located; When multiple nodes are located in different bone branches, update the second bone that does not contain multiple nodes; wherein, one of the first bone and the second bone is the initial source bone, and the other is the initial target bone.

因此，通過更新多個節點所在的第一骨骼，使得兩個骨骼之間的多個節點映射於同一節點的情況調整為兩個骨骼之間的節點一一映射，進而減少後續動畫驅動最終目標骨骼的過程中出現不合理的情況出現。Therefore, by updating the first bone where multiple nodes are located, the situation that multiple nodes between two bones are mapped to the same node is adjusted to a node-to-one mapping between two bones, thereby reducing the subsequent animation driving the final target bone Unreasonable situations appear in the process.

在一些實施例中，更新多個節點所在的第一骨骼，包括：將第一骨骼中的多個節點合併為一個第一節點，其中，第一節點保留合併前多個節點的映射關係；和/或，更新不包含多個節點的第二骨骼，包括：在第一骨骼中查找出多個節點所在的骨骼分支匯合的第二節點，並在第二骨骼中查找出映射於第二節點的第三節點；按照多個節點對應的節點拓撲結構，在第三節點處新增至少一條骨骼分支，其中，多個節點與第三節點處新增的骨骼分支和原始的骨骼分支中的節點一一映射。In some embodiments, updating the first bone where the multiple nodes are located includes: merging the multiple nodes in the first bone into one first node, wherein the first node retains the mapping relationship of the multiple nodes before merging; and /or, update the second bone that does not contain multiple nodes, including: find out in the first bone the second node where the bone branches where the multiple nodes are located converge, and find out in the second bone that is mapped to the second node The third node; according to the node topology corresponding to the multiple nodes, add at least one bone branch at the third node, wherein the multiple nodes are the same as the new bone branch at the third node and the nodes in the original bone branch a map.

因此，通過此種方式在實現節點一一映射的情況下，還能夠最大化的保留第一骨骼的節點拓撲結構。Therefore, in the case of implementing node-to-node mapping in this way, the node topology of the first bone can also be preserved to the greatest extent.

在一些實施例中，在將與初始源骨骼相關的第一動畫驅動資料遷移至最終目標骨骼上，得到最終目標骨骼的第二動畫驅動資料之前，方法還包括：按照從根源節點到葉源節點的順序，分別將最終源骨骼中的各源節點與最終目標骨骼中對應映射的目標節點進行對齊，以得到各源節點與映射的目標節點之間的第一位姿變換關係；將與初始源骨骼相關的第一動畫驅動資料遷移至最終目標骨骼上，得到最終目標骨骼的第二動畫驅動資料，包括：利用第一動畫驅動資料和第一位姿變換關係，得到最終目標骨骼的第二動畫驅動資料。In some embodiments, before migrating the first animation driving data related to the initial source bone to the final target bone to obtain the second animation driving data of the final target bone, the method further includes: Align each source node in the final source bone with the corresponding mapped target node in the final target bone to obtain the first pose transformation relationship between each source node and the mapped target node; The first animation driving data related to the bone is transferred to the final target bone to obtain the second animation driving data of the final target bone, including: using the first animation driving data and the first pose transformation relationship to obtain the second animation of the final target bone Driver data.

因此，通過進行源節點與目標節點之間的對齊，就能夠得到各源節點與映射的目標節點之間的第一位姿變換關係，由此實現利用第一動畫驅動資料和第一位姿變換關係，得到最終目標骨骼的第二動畫驅動資料。Therefore, by aligning the source node and the target node, the first pose transformation relationship between each source node and the mapped target node can be obtained, thereby realizing the use of the first animation driving data and the first pose transformation relationship to get the second animation-driven data of the final target bone.

在一些實施例中，分別將最終源骨骼中的各源節點與最終目標骨骼中對應的目標節點進行對齊，以得到各源節點與映射的目標節點之間的第一位姿變換關係，包括：對於最終源骨骼中的每個源節點，獲取使源節點對齊於映射的目標節點所需的偏移量，其中，偏移量包括平移分量和旋轉分量中的至少一者；基於源節點對應的偏移量，得到源節點的第一位姿變換關係。In some embodiments, each source node in the final source bone is aligned with the corresponding target node in the final target bone, so as to obtain the first pose transformation relationship between each source node and the mapped target node, including: For each source node in the final source bone, obtain the offset required to align the source node to the mapped target node, where the offset includes at least one of a translation component and a rotation component; based on the corresponding Offset, get the first pose transformation relationship of the source node.

因此，偏移量包括平移分量和旋轉分量，使得獲取到的第一位姿變換關係更準確。Therefore, the offset includes a translation component and a rotation component, so that the obtained first pose transformation relationship is more accurate.

在一些實施例中，最終源骨骼的根源節點和最終目標骨骼的根目標節點均平移至第一座標系的原點，第一位姿變換關係為源節點與映射的目標節點在第一座標系中的變換關係；源節點對應的偏移量為：在源節點的第一父節點對齊且第一父節點作為第二座標系的原點的情況下，源節點與映射的目標節點在第二座標系中的偏移量。In some embodiments, both the root node of the final source bone and the root target node of the final target bone are translated to the origin of the first coordinate system, and the first pose transformation relationship is that the source node and the mapped target node are in the first coordinate system The transformation relationship in ; the offset corresponding to the source node is: when the first parent node of the source node is aligned and the first parent node is the origin of the second coordinate system, the source node and the mapped target node are in the second The offset in the coordinate system.

因此，通過最終源骨骼的根源節點和最終目標骨骼的根目標節點均平移至第一座標系的原點，能夠獲取最終源骨骼的根源節點和最終目標骨骼的根目標節點之間的偏移量。Therefore, by translating the root node of the final source bone and the root target node of the final target bone to the origin of the first coordinate system, the offset between the root node of the final source bone and the root target node of the final target bone can be obtained .

在一些實施例中，獲取使源節點對齊於映射的目標節點所需的偏移量，包括：獲取經對齊的第一父節點與根源節點之間的第二位姿變換關係、以及源節點映射的目標節點的第二父節點與根目標節點之間的第三位姿變換關係，基於源節點以及映射的目標節點在第一座標系中的位姿以及第二位姿變換關係和第三位姿變換關係，得到源節點對應的偏移量；和/或，基於源節點對應的偏移量，得到源節點的第一位姿變換關係，包括：基於源節點以及源節點的上級節點分別對應的偏移量，得到源節點的第一位姿變換關係，其中，源節點的上級節點為最終源骨骼中源節點的第一父節點、根源節點以及第一父節點與根源節點之間的節點。In some embodiments, obtaining the offset required to align the source node to the mapped target node includes: obtaining the second pose transformation relationship between the aligned first parent node and the root node, and the source node mapping The third pose transformation relationship between the second parent node of the target node and the root target node, based on the pose of the source node and the mapped target node in the first coordinate system, the second pose transformation relationship and the third position and/or, based on the offset corresponding to the source node, obtain the first pose transformation relationship of the source node, including: based on the source node and the parent node of the source node corresponding to , to get the first pose transformation relationship of the source node, where the superior node of the source node is the first parent node of the source node in the final source bone, the root node, and the nodes between the first parent node and the root node .

因此，通過結合源節點以及源節點的上級節點對應的偏移量，就能夠得到源節點在第一座標系中與映射的目標節點的第一位姿變換關係。Therefore, the first pose transformation relationship between the source node and the mapped target node in the first coordinate system can be obtained by combining the source node and the offset corresponding to the source node's superior node.

在一些實施例中，第一動畫驅動資料是基於最終源骨骼與初始源骨骼之間的拓撲結構差異，對初始源骨骼的原始動畫資料進行調整得到的；和/或最終目標骨骼的第二動畫驅動資料是基於第一動畫驅動資料以及第一位姿變換關係得到，其中，第一位姿變換關係為最終源骨骼的源節點與最終目標骨骼中映射的目標節點之間的變換關係；最終目標骨骼為目標對象的骨骼；將與初始源骨骼相關的第一動畫驅動資料遷移至最終目標骨骼上，得到最終目標骨骼的第二動畫驅動資料，包括：基於目標對象中的幾何網格頂點的第一位置資訊、第一動畫驅動資料以及第一位姿變換關係，得到第二動畫驅動資料中關於幾何網格頂點的第二位置資訊。In some embodiments, the first animation driving data is obtained by adjusting the original animation data of the initial source bone based on the topology difference between the final source bone and the initial source bone; and/or the second animation of the final target bone The driving data is obtained based on the first animation driving data and the first pose transformation relationship, wherein the first pose transformation relationship is the transformation relationship between the source node of the final source bone and the target node mapped in the final target bone; the final target The bone is the bone of the target object; the first animation driving data related to the initial source bone is transferred to the final target bone to obtain the second animation driving data of the final target bone, including: the first animation driving data based on the geometric mesh vertices in the target object The first position information, the first animation driving data and the first pose transformation relationship are used to obtain the second position information about the vertices of the geometric mesh in the second animation driving data.

因此，通過考慮參考節點對頂點的影響權重，使得獲取得到的幾何網格頂點的第二位置資訊更為準確。Therefore, by considering the influence weight of the reference node on the vertex, the obtained second position information of the vertex of the geometric mesh is more accurate.

在一些實施例中，獲取初始源骨骼，包括：對包含目標對象的圖像進行分類，得到目標對象的類別，並選擇與類別匹配的骨骼模型作為初始源骨骼，其中，最終目標骨骼為目標對象的骨骼；和/或，獲取初始目標骨骼，包括：對包含目標對象的圖像進行輪廓提取，得到目標對象的輪廓；利用輪廓，為目標對象生成三維網格模型；從三維網格模型中提取得到初始目標骨骼。In some embodiments, obtaining the initial source bone includes: classifying the image containing the target object to obtain the category of the target object, and selecting a bone model matching the category as the initial source bone, wherein the final target bone is the target object and/or, obtaining the initial target bone, including: extracting the outline of the image containing the target object to obtain the outline of the target object; using the outline to generate a three-dimensional mesh model for the target object; extracting from the three-dimensional mesh model Get the initial target bone.

應當理解的是，以上的一般描述和後文的細節描述僅是示例性和解釋性的，而非限制本發明實施例。It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only, rather than limiting the embodiments of the present invention.

下面結合說明書附圖，對本發明實施例的方案進行詳細說明。The solutions of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

以下描述中，為了說明而不是為了限定，提出了諸如特定系統結構、介面、技術之類的具體細節，以便透徹理解本發明實施例。In the following description, specific details such as specific system structures, interfaces, and technologies are presented for illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention.

本文中術語“和/或”，僅僅是一種描述關聯對象的關聯關係，表示可以存在三種關係，例如，A和/或B，可以表示：單獨存在A，同時存在A和B，單獨存在B這三種情況。另外，本文中字元“/”，一般表示前後關聯對象是一種“或”的關係。此外，本文中的“多”表示兩個或者多於兩個。另外，本文中術語“至少一種”表示多種中的任意一種或多種中的至少兩種的任意組合，例如，包括A、B、C中的至少一種，可以表示包括從A、B和C構成的集合中選擇的任意一個或多個元素。The term "and/or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and/or B can mean: A exists alone, A and B exist at the same time, and B exists alone. three conditions. In addition, the character "/" in this article generally indicates that the contextual objects are an "or" relationship. In addition, "many" herein means two or more than two. In addition, the term "at least one" herein means any one or any combination of at least two of the plurality, for example, including at least one of A, B, and C, may mean including the composition consisting of A, B, and C Any one or more elements selected in the collection.

相關技術中的動畫遷移技術要求現有的骨骼模型與新的骨骼模型的拓撲結構需要完全一致，即只有在兩個骨骼模型的拓撲結構完全一致的基礎上才能實現動畫遷移。但是，新的骨骼模型的形式多種多樣，無法對每種骨骼模型都構建拓撲結構一模一樣的具有動畫資料的骨骼模型，導致相關技術中現有的具備動畫資料的骨骼模型的適用性較低。The animation migration technology in the related art requires that the topological structures of the existing skeleton model and the new skeleton model need to be completely consistent, that is, the animation migration can only be realized on the basis that the topological structures of the two skeleton models are completely consistent. However, the new skeletal models come in a variety of forms, and it is impossible to construct skeletal models with the same topological structure with animation data for each of the skeletal models, resulting in low applicability of the existing skeletal models with animation data in the related art.

針對以上方案所存在的缺陷，均是發明人在經過實踐並仔細研究後得出的結果，因此，上述問題的發現過程以及下文中本發明實施例針對上述問題所提出的解決方案，都應該是發明人在本發明過程中對本發明做出的貢獻。The defects in the above solutions are all the results obtained by the inventor after practice and careful research.

其中，這裡的初始源骨骼指的是攜帶有動畫驅動資料的骨骼，而初始目標骨骼指的是沒有攜帶動畫驅動資料的骨骼。其中，本發明實施例提出的動畫遷移方法實際上就是為了將初始源骨骼攜帶的動畫驅動資料遷移到初始目標骨骼上，以驅動初始目標骨骼依照動畫驅動資料運動。Among them, the initial source bone here refers to the bone that carries the animation driving data, and the initial target bone refers to the bone that does not carry the animation driving data.

初始源骨骼和初始目標骨骼均可以看做是多個節點構建而成，初始源骨骼和初始目標骨骼之間的節點映射關係也就指的是兩個骨骼的節點之間的對應關係。Both the initial source bone and the initial target bone can be regarded as constructed from multiple nodes, and the node mapping relationship between the initial source bone and the initial target bone refers to the corresponding relationship between the nodes of the two bones.

步驟S12：基於節點映射關係更新初始源骨骼和目標骨骼中至少一者的節點拓撲結構，得到最終源骨骼和最終目標骨骼，其中，最終目標骨骼中的目標節點均能夠映射於所述最終源骨骼中的源節點。Step S12: Update the node topology of at least one of the initial source bone and the target bone based on the node mapping relationship to obtain the final source bone and the final target bone, wherein the target nodes in the final target bone can all be mapped to the final source bone source node in .

初始源骨骼的拓撲結構和初始目標骨骼的拓撲結構可能不相同。例如，初始源骨骼中存在沒有與初始目標骨骼構建映射關係的冗餘的節點，而初始目標骨骼中同樣也可能存在沒有與初始源骨骼構建映射關係的冗餘的節點。如果此時不對初始源骨骼和初始目標骨骼進行更新，直接將初始源骨骼攜帶的動畫驅動資料遷移到初始目標骨骼上，很可能導致初始目標骨骼的動畫驅動效果與初始源骨骼的動畫驅動效果存在較大的差異，無法實現原本動畫遷移的目的。The topology of the initial source bone may not be the same as the topology of the initial target bone. For example, there are redundant nodes in the initial source bone that do not establish a mapping relationship with the initial target bone, and there may also be redundant nodes in the initial target bone that do not establish a mapping relationship with the initial source bone. If the initial source bone and initial target bone are not updated at this time, and the animation driving data carried by the initial source bone is directly migrated to the initial target bone, it is likely to cause the animation driving effect of the initial target bone and the animation driving effect of the initial source bone to exist. The large difference cannot achieve the purpose of the original animation migration.

因此，本發明實施例基於二者之間的節點映射關係更新初始源骨骼和/或初始目標骨骼，使得最終目標骨骼中的目標節點均能映射於最終源骨骼中的源節點。Therefore, the embodiment of the present invention updates the initial source bone and/or the initial target bone based on the node mapping relationship between them, so that all target nodes in the final target bone can be mapped to source nodes in the final source bone.

步驟S13：將與初始源骨骼相關的第一動畫驅動資料遷移至最終目標骨骼上，得到最終目標骨骼的第二驅動資料。Step S13: Migrating the first animation driving data related to the initial source bone to the final target bone to obtain the second driving data of the final target bone.

其中，如果最終源骨骼的拓撲結構與初始源骨骼的拓撲結構一致，則與初始源骨骼相關的第一動畫驅動資料與初始源骨骼的動畫驅動資料相同。如果，最終源骨骼的拓撲結構被更新過，則最終源骨骼的第一動畫驅動資料則與初始源骨骼的動畫驅動資料不同。當然，最終源骨骼的第一動畫驅動資料可根據其拓撲結構的變化，相應的做出變化。例如，初始源骨骼的源節點A與其子節點B融合為了一個節點C，得到最終源骨骼的拓撲結構，此時，最終源骨骼中節點C的動畫資料可以是源節點A與其子節點B的動畫資料的融合。當然，在其他實施例中，若出現兩個源節點合併的情況時，還可刪除兩個源節點中的子節點的動畫驅動資料。Wherein, if the topology structure of the final source bone is consistent with the topology structure of the initial source bone, then the first animation driving data related to the initial source bone is the same as the animation driving data of the initial source bone. If the topology structure of the final source bone is updated, the first animation driving data of the final source bone is different from the animation driving data of the initial source bone. Of course, the first animation driving data of the final source bone can be changed accordingly according to the change of its topological structure. For example, the source node A of the initial source bone and its child node B are fused into a node C to obtain the topology of the final source bone. At this time, the animation data of node C in the final source bone can be the animation of source node A and its child node B Fusion of data. Of course, in other embodiments, if two source nodes are merged, the animation driving data of the child nodes in the two source nodes can also be deleted.

在本發明的一些實施例中，獲取初始源骨骼的方式可以是：對包含目標對象的圖像進行分類，得到目標對象的類別，並選擇與類別匹配的骨骼模型作為初始源骨骼。其中，最終目標骨骼為目標對象的骨骼。本發明實施例可以採用預測標籤映射，也可以採用資料集標籤映射。二者不同的是，預測標籤映射對目標對象的分類結果包括目標對象的預測骨骼拓撲結構類型，例如預測骨骼拓撲結構類型包括二足、四足等等。也就是，預測標籤映射的過程主要是預測目標對象的骨骼拓撲結構特點。而資料集標籤映射的分類結果需要給出輸入圖像中目標對象的具體種類，例如目標對象為貓、狗、大熊貓、狗熊等等。本發明實施例選擇採用預測標籤映射，應用過程中，若目標對象為大熊貓，而預測標籤映射給出的目標對象類別為四足，並選擇與類別匹配的骨骼模型作為初始源骨骼，若選擇的初始源骨骼為四足的狗熊。雖然大熊貓和狗熊不同，但是他們實際上具有大致相同的骨骼拓撲結構，因此，將狗熊的動畫驅動資料遷移到大熊貓上也能夠以自然合理的形式出現。也就是通過預測標籤映射雖然無法得到完全正確的目標對象的類別，但是也不影響對最終目標骨骼的驅動。同時，因為預測標籤映射沒有進一步獲知目標對象的具體類別，從而降低了計算成本。In some embodiments of the present invention, the manner of obtaining the initial source skeleton may be: classify the image containing the target object, obtain the category of the target object, and select a bone model matching the category as the initial source skeleton. Wherein, the final target bone is the bone of the target object. In the embodiment of the present invention, prediction label mapping may be used, or data set label mapping may be used. The difference between the two is that the classification result of the target object by the predicted label mapping includes the predicted skeletal topology type of the target object, for example, the predicted skeletal topology type includes biped, quadruped and so on. That is, the process of predicting label mapping is mainly to predict the skeletal topological structure characteristics of the target object. The classification result of the label mapping of the dataset needs to give the specific type of the target object in the input image, for example, the target object is a cat, a dog, a giant panda, a bear, and so on. The embodiment of the present invention chooses to use predicted label mapping. During the application process, if the target object is a giant panda, and the category of the target object given by the predicted label mapping is quadruped, and the bone model matching the category is selected as the initial source bone, if selected The initial source skeleton for is a quadruped bear. Although giant pandas and bears are different, they actually have roughly the same bone topology. Therefore, migrating the animation-driven data of bears to giant pandas can also appear in a natural and reasonable form. That is, although the completely correct category of the target object cannot be obtained by predicting the label mapping, it does not affect the driving of the final target bone. At the same time, the computational cost is reduced because the predicted label map does not further learn the specific category of the target object.

獲取初始目標骨骼的方式可以是：對包含目標對象的圖像進行輪廓提取，得到目標對象的輪廓。其中，提取輪廓的方式可以是進行目標分割，得到清晰的目標對象的輪廓。利用輪廓，為目標對象生成三維網格模型。一般地，可以將目標對象的輪廓簡化為多邊形，並應用三角剖分得到對應二維的三角形網格。然後三角形法線方向從二維的三角形中擠出三維網格模型。並從三維網格模型中提取得到初始目標骨骼。在本發明的一些實施例中，可以使用平均曲率法從三維網格中提取初始目標骨骼。其中，在提取得到初始目標骨骼之後，判斷提取得到的初始目標骨骼是否滿足解剖結構是否相差過大。例如，骨骼拓撲結構中，對於連續的、長度相差過大的骨骼進行重新採樣，以得到長度均勻的骨骼拓撲結構，例如連續的三個骨骼節點為A、B、C，其中，節點A與節點B之間的骨骼長度為2米，而節點B和節點C之間的骨骼長度為0.1米，因此，可以對節點A至C之間的骨骼進行重新採樣，使得節點A與節點B之間的骨骼長度為1.05米，節點A與節點B之間的骨骼長度為1.05米。當然，還可以在節點A至C之間增加新的節點，從而縮短相鄰節點之間的骨骼長度。同理，若連續相鄰節點之間的骨骼長度過短，不符合常規的解剖結構，可以將其中部分節點合併，減少節點數量，從而增加相鄰節點之間的骨骼結構。A manner of obtaining the initial target skeleton may be: performing contour extraction on an image containing the target object to obtain the contour of the target object. Wherein, the manner of extracting the contour may be to perform target segmentation to obtain a clear contour of the target object. Using the outline, a 3D mesh model is generated for the target object. Generally, the outline of the target object can be simplified into a polygon, and the corresponding two-dimensional triangular mesh can be obtained by applying triangulation. The triangle normal direction then extrudes the 3D mesh from the 2D triangles. And extract the initial target bone from the 3D mesh model. In some embodiments of the present invention, the average curvature method can be used to extract the initial target bone from the three-dimensional mesh. Wherein, after the initial target bone is extracted, it is judged whether the extracted initial target bone satisfies the anatomical structure or whether the difference is too large. For example, in the skeletal topology, resample continuous bones with large length differences to obtain a skeletal topology with uniform length. For example, three consecutive bone nodes are A, B, and C, where node A and node B The bone length between nodes A and C is 2 meters, and the bone length between nodes B and C is 0.1 meters. Therefore, the bones between nodes A and C can be resampled so that the bones between nodes A and B The length is 1.05 meters, and the length of the bone between node A and node B is 1.05 meters. Of course, new nodes can also be added between nodes A to C, so as to shorten the bone length between adjacent nodes. Similarly, if the bone length between consecutive adjacent nodes is too short and does not conform to the conventional anatomical structure, some of the nodes can be merged to reduce the number of nodes, thereby increasing the bone structure between adjacent nodes.

在本發明的一些實施例中，獲取初始源骨骼和初始目標骨骼之間的節點映射關係的方式可以有多種：例如，確定初始源骨骼和初始目標骨骼中各節點所在的骨骼分支數量。按照骨骼分支數量從多到少的順序，依序對初始源骨骼和初始目標骨骼中的節點進行映射。其中，所在的骨骼分支數量最多的節點一般稱之為根節點。其中，暫且將節點所在的骨骼分支數量稱之為度數。也就是先構建兩個骨骼中度數較大的節點之間的映射關係，再構建度數較少的節點之間的映射關係。又或者，可以採用骨骼分支映射誤差值最小的原則進行映射。其中，如果初始源骨骼和初始目標骨骼之間的節點數不同，則選擇成本最低的最小多對一映射。例如，可以通過在發生多對一或跳過映射的序列中執行一對一的聯合匹配的方式進行映射。 In some embodiments of the present invention, there are multiple ways to obtain the node mapping relationship between the initial source bone and the initial target bone: For example, determine the number of bone branches for each node in the initial source bone and the initial target bone. The nodes in the initial source bone and the initial target bone are mapped sequentially in descending order of the number of bone branches. Among them, the node with the largest number of bone branches is generally called the root node. Among them, for the time being, the number of skeletal branches where the nodes are located is called the degree. That is, first construct the mapping relationship between nodes with larger degrees in the two bones, and then construct the mapping relationship between nodes with less degrees. Alternatively, the principle of minimum error value of bone branch mapping can be used for mapping. Among them, if the number of nodes between the initial source bone and the initial target bone is different, the smallest many-to-one mapping with the lowest cost is chosen. For example, mapping can be done by performing a one-to-one joint matching in the sequence in which many-to-one or skip mapping occurs.

在本發明的一些實施例中，可以使用以下方式進一步為沒有構建映射關係的節點構建映射關係。In some embodiments of the present invention, the following methods may be used to further construct mapping relationships for nodes that have not established mapping relationships.

例如，若當前源節點只有一個子節點的情況下，也就是當前源節點不是骨骼分支的匯合點的情況下，可以參考其子節點的映射關係。例如構建與其子節點具備映射關係的目標節點之間的映射關係。或者，當前源節點是骨骼分支的匯合點的情況下，則根據多條骨骼分支的節點進行合併，去上限節點。又或者，不滿足上述任何條件的情況下，則預設映射初始目標骨骼的根節點。當然，在本發明的一些實施例中，若按照骨骼分支數量從多到少的順序得到二者之間的映射關係之後，有的源節點沒有對應的目標節點與之映射的情況下，也可以不對其進一步構建映射關係。For example, if the current source node has only one child node, that is, when the current source node is not the meeting point of the skeletal branches, the mapping relationship of its child nodes can be referred to. For example, construct a mapping relationship between target nodes that have a mapping relationship with their child nodes. Or, if the current source node is the confluence point of the skeletal branch, merge according to the nodes of multiple skeletal branches, and remove the upper limit node. Or, if any of the above conditions are not met, the root node of the initial target bone is preset to be mapped. Of course, in some embodiments of the present invention, after obtaining the mapping relationship between the two according to the order of the number of skeletal branches from more to less, some source nodes do not have corresponding target nodes to map with, you can also No further mapping relationship is built on it.

通過獲取目標對象的類別，並從與類別匹配的骨骼模型中選擇初始源骨骼，方便快捷。通過按照骨骼分支數量從多到少的順序，依序對初始骨骼和初始目標骨骼中的節點進行映射，能夠提高映射的準確度。It is convenient and quick by getting the category of the target object and selecting the initial source bone from the bone model matching the category. By sequentially mapping the nodes in the initial bone and the initial target bone in order of the number of bone branches from large to small, the accuracy of mapping can be improved.

在本發明的一些實施例中，最終目標骨骼與最終源骨骼的節點拓撲結構一致，和/或，最終目標骨骼與最終源骨骼之間的節點一一映射。也就是，最終目標骨骼與最終源骨骼的節點拓撲結構可能存在兩種形式，一種是最終目標骨骼與最終源骨骼的節點拓撲結構完全一致，另一種是最終目標骨骼中的節點均有最終源骨骼的節點與之對應，但是最終源骨骼中存在一些沒有構建映射關係的節點。即，需要保證在動畫遷移後，最終目標骨骼的節點上均有對應的動畫驅動資料。In some embodiments of the present invention, the node topology of the final target bone is consistent with that of the final source bone, and/or, the nodes between the final target bone and the final source bone are mapped one by one. That is to say, there may be two forms of the node topology of the final target bone and the final source bone, one is that the node topology of the final target bone is completely consistent with the final source bone, and the other is that the nodes in the final target bone have the final source bone The nodes correspond to it, but there are some nodes in the final source bone that do not have a mapping relationship. That is, it is necessary to ensure that after animation migration, the nodes of the final target bone have corresponding animation driving data.

在本發明的一些實施例中，節點映射關係包括初始源骨骼和初始目標骨骼中的節點之間的映射關係。In some embodiments of the present invention, the node mapping relationship includes a mapping relationship between nodes in the initial source bone and the initial target bone.

基於節點對應關係更新初始源骨骼和初始目標骨骼中至少一者的節點拓撲結構，得到最終源骨骼和最終目標骨骼，包括以下至少之一：一是在兩個骨骼之間存在多個節點映射於同一節點的情況下，更新其中一個骨骼的節點拓撲結構。其中，兩個骨骼包括初始源骨骼和初始目標骨骼，經更新之後的兩個骨骼之間的節點一一映射。通過更新骨骼的節點拓撲結構能夠使得兩個骨骼之間的多個節點映射於同一節點的情況調整為兩個骨骼之間的節點一一映射，以減少後續動畫驅動最終目標骨骼的過程中出現不合理的情況出現。 The node topology structure of at least one of the initial source bone and the initial target bone is updated based on the node correspondence to obtain the final source bone and the final target bone, including at least one of the following: One is to update the node topology of one of the bones when there are multiple nodes mapped to the same node between the two bones. Wherein, the two bones include an initial source bone and an initial target bone, and the updated nodes between the two bones are mapped one by one. By updating the node topology of the bone, the situation that multiple nodes between two bones are mapped to the same node can be adjusted to a node-to-one mapping between the two bones, so as to reduce the occurrence of inconsistencies in the process of driving the final target bone in the subsequent animation. Reasonable situations arise.

在本發明的一些實施例中，更新其中一個骨骼的節點拓撲結構又可分為多種情況：第一種情況是在多個節點位於同一骨骼分支的情況下，更新多個節點所在的第一骨骼。其中，第一骨骼和第二骨骼中的其中一個為初始源骨骼，另一個為目標骨骼。通過更新多個節點所在的第一骨骼，使得兩個骨骼之間的多個節點映射於同一節點的情況調整為兩個骨骼之間的節點一一映射，進而減少後續動畫驅動最終目標骨骼的過程中出現不合理的情況出現。In some embodiments of the present invention, updating the node topology of one of the bones can be divided into multiple cases: the first case is to update the first bone where multiple nodes are located when multiple nodes are located in the same bone branch . Wherein, one of the first bone and the second bone is the initial source bone, and the other is the target bone. By updating the first bone where multiple nodes are located, the situation that multiple nodes between two bones are mapped to the same node is adjusted to a node-to-one mapping between two bones, thereby reducing the process of subsequent animation driving the final target bone Unreasonable situations occur.

在本發明的一些實施例中，更新多個節點所在的第一骨骼的方式可以是將第一骨骼中的多個節點合併為一個第一節點。其中，第一節點保留合併前多個節點的映射關係。並且，第一節點的位置取所有被合併節點的位置的平均值。同時參見圖2，圖2是本發明實施例提供的一種動畫遷移方法中映射關係示意圖。如圖2所示，初始目標骨骼中的第二個節點201和第三個節點202同時映射於初始源骨骼中的第二個節點211時。在這種情況下，將初始目標骨骼中的第二個節點201和第三個節點202進行合併為一個第一節點。其中，第一節點的位置取初始目標骨骼中第二個節點201和第三個節點202的位置的平均值。其中，當第一骨骼為初始源骨骼時，因為初始源骨骼中的節點攜帶有動畫驅動資料，所以當節點合併之後，需要獲取第一節點的動畫驅動資料，此時，可以將被合併的所有節點的動畫驅動資料進行合併。在本發明一些實施例中，動畫驅動資料一般可以用矩陣表示，矩陣的合併可以用矩陣乘法表示，即將動畫驅動資料進行相乘，即可得到第一節點的動畫驅動資料。第二種情況是在多個節點位於不同骨骼分支的情況下，更新不包括多個節點的第二骨骼。其中，第一骨骼和第二骨骼中的其中一個為初始源骨骼，另一個為目標骨骼。在本發明一些實施例中，在第一骨骼中查找出多個節點所在的骨骼分支匯合的第二節點。具體做法可以是依次父節點遍歷，從而得到第二節點。並在第二骨骼中查找出映射於第二節點的第三節點。然後找找多個節點對應的節點拓撲結構，在第三節點處新增至少一條骨骼分支。本發明實施例中，一個節點的父節點指的是在一條骨骼分支中，與該節點相鄰且比該節點更靠近根節點的節點。其中，多個節點與第三節點處新增的骨骼分支和原始的骨骼分支中的節點一一映射。其中，新增的骨骼分支可以是複製原始的骨骼分支。複製的內容包括動畫資料、以及該節點與其父節點之間的變換關係。例如，原始的骨骼分支中包括三個節點，則新增的骨骼分支中也包括三個節點，且新增的骨骼分支中的三個節點的動畫驅動資料是通過複製原始的骨骼分支中對應節點的動畫資料得到。同時參見圖3，圖3是本發明實施例提供的一種動畫遷移方法中映射關係示意圖。如圖3所示，左邊的節點拓撲結構為初始源骨骼的節點拓撲結構，右邊的節點拓撲結構為初始目標骨骼的節點拓撲結構。圖3中，初始目標骨骼的第一個節點301映射於初始源骨骼的第一個節點311，初始目標骨骼的第二個節點302映射於初始源骨骼的第二個節點312，初始目標骨骼的第二個節點302下包括兩個分支，即左分支與右分支，其中，左分支中的第一個節點3021和右分支中的第一個節點3022映射於初始源骨骼的第三個節點313，左分支中的第二個節點3023和右分支中的第二個節點3024映射於初始源骨骼的第四個節點314。這也就出現了初始目標骨骼中兩個節點映射於初始源骨骼的第三個節點313，且這兩個節點屬於不同的分支，以及初始目標骨骼中兩個節點映射於初始源骨骼的第四個節點314，且這兩個節點屬於不同的分支。其中，這兩個分支匯合在初始目標骨骼的第二個節點302。在初始源骨骼中找出映射於初始目標骨骼的第二個節點302為第二個節點。按照初始目標骨骼這兩個節點對應的節點拓撲結構，在初始源骨骼的第二個節點處新增一條骨骼分支。其中，新增的一條骨骼分支中的節點有兩個。此時，初始目標骨骼中所有的節點均一一對應與初始源骨骼中的節點。因此，通過此種方式在實現節點一一映射的情況下，還能夠最大化的保留第一骨骼的節點拓撲結構。In some embodiments of the present invention, the manner of updating the first bone where the multiple nodes are located may be to merge the multiple nodes in the first bone into one first node. Wherein, the first node retains the mapping relationship of multiple nodes before merging. And, the position of the first node is the average value of the positions of all merged nodes. Also refer to FIG. 2 . FIG. 2 is a schematic diagram of a mapping relationship in an animation migration method provided by an embodiment of the present invention. As shown in FIG. 2 , the second node 201 and the third node 202 in the initial target bone are mapped to the second node 211 in the initial source bone at the same time. In this case, the second node 201 and the third node 202 in the initial target bone are merged into one first node. Wherein, the position of the first node is the average value of the positions of the second node 201 and the third node 202 in the initial target bone. Among them, when the first bone is the initial source bone, because the nodes in the initial source bone carry animation driving data, after the nodes are merged, it is necessary to obtain the animation driving data of the first node. At this time, all merged The animation driver data for the node is merged. In some embodiments of the present invention, the animation driving data can generally be represented by a matrix, and the combination of the matrices can be represented by matrix multiplication, that is, the animation driving data of the first node can be obtained by multiplying the animation driving data. The second case is to update the second bone that does not include the multiple nodes when the multiple nodes are located on different bone branches. Wherein, one of the first bone and the second bone is the initial source bone, and the other is the target bone. In some embodiments of the present invention, the second node where the branches of the bones where the multiple nodes are located converges is found in the first bone. A specific method may be to traverse the parent nodes in turn to obtain the second node. And find out the third node mapped to the second node in the second bone. Then find the node topology corresponding to multiple nodes, and add at least one bone branch at the third node. In the embodiment of the present invention, a parent node of a node refers to a node adjacent to the node and closer to the root node than the node in a skeletal branch. Wherein, multiple nodes are mapped one by one with the nodes in the newly added bone branch at the third node and the original bone branch. Wherein, the newly-added bone branch may copy the original bone branch. The copied content includes animation data and the transformation relationship between this node and its parent node. For example, if the original bone branch includes three nodes, the new bone branch also includes three nodes, and the animation driving data of the three nodes in the new bone branch is copied from the corresponding nodes in the original bone branch The animation data obtained. Also refer to FIG. 3 . FIG. 3 is a schematic diagram of a mapping relationship in an animation transition method provided by an embodiment of the present invention. As shown in Figure 3, the node topology on the left is the node topology of the initial source bone, and the node topology on the right is the node topology of the initial target bone. In Fig. 3, the first node 301 of the initial target bone is mapped to the first node 311 of the initial source bone, the second node 302 of the initial target bone is mapped to the second node 312 of the initial source bone, and the The second node 302 includes two branches, namely the left branch and the right branch, wherein the first node 3021 in the left branch and the first node 3022 in the right branch are mapped to the third node 313 of the initial source bone , the second node 3023 in the left branch and the second node 3024 in the right branch are mapped to the fourth node 314 of the original source bone. This means that two nodes in the initial target bone are mapped to the third node 313 of the initial source bone, and these two nodes belong to different branches, and two nodes in the initial target bone are mapped to the fourth node of the initial source bone. nodes 314, and these two nodes belong to different branches. Wherein, these two branches converge at the second node 302 of the initial target bone. Find the second node 302 mapped to the initial target bone in the initial source bone as the second node. According to the node topology corresponding to the two nodes of the initial target bone, a new bone branch is added at the second node of the initial source bone. Among them, there are two nodes in the newly added bone branch. At this point, all the nodes in the initial target bone correspond to the nodes in the initial source bone. Therefore, in the case of implementing node-to-node mapping in this way, the node topology of the first bone can also be preserved to the greatest extent.

二是在骨骼中存在未有映射關係的情況下，更新未有映射關係的節點所在骨骼的節點拓撲結構。其中，兩個骨骼包括初始源骨骼和初始目標骨骼，經更新之後的兩個骨骼之間的節點一一映射。通過更新沒有映射關係的節點所在骨骼的節點拓撲結構，減少沒有映射關係的節點，使得更新後的兩個骨骼之間的節點一一映射，從而減少後續動畫驅動最終目標骨骼的過程中出現不合理的情況出現。在本發明一些實施例中，將未有映射關係的節點合併至具有映射關係的相鄰節點。其中，相鄰節點為未有映射關係的節點在所在骨骼中的父節點或子節點。本發明實施例中將未有映射關係的節點向其父節點合併。請參見圖4，圖4是本發明實施例提供的一種動畫遷移方法中映射關係示意圖。如圖4所示，初始目標骨骼的第一個節點401映射於初始源骨骼的第一個節點411，初始目標骨骼的第二個節點402映射於初始源骨骼的第三個節點413，初始目標骨骼的第三個節點403映射於初始源骨骼的第四個節點414。其中，初始源骨骼的第二個節點412沒有映射關係。可以將初始源骨骼的第二個節點412向其父節點合併，也就是向初始源骨骼的第一個節點401合併。當然，初始源骨骼中的節點合併都會伴隨著動畫驅動資料之間的合併。The second is to update the node topology of the bone where the node without the mapping relationship exists when there is no mapping relationship in the bone. Wherein, the two bones include an initial source bone and an initial target bone, and the updated nodes between the two bones are mapped one by one. By updating the node topology of the bone where the node without the mapping relationship is located, the number of nodes without the mapping relationship is reduced, so that the nodes between the updated two bones are mapped one by one, thereby reducing the irrationality in the process of driving the final target bone in the subsequent animation situation occurs. In some embodiments of the present invention, nodes without a mapping relationship are merged into adjacent nodes with a mapping relationship. Among them, the adjacent node is the parent node or child node in the bone where the node has no mapping relationship. In the embodiment of the present invention, nodes without a mapping relationship are merged to their parent nodes. Please refer to FIG. 4 . FIG. 4 is a schematic diagram of a mapping relationship in an animation transition method provided by an embodiment of the present invention. As shown in Figure 4, the first node 401 of the initial target bone is mapped to the first node 411 of the initial source bone, the second node 402 of the initial target bone is mapped to the third node 413 of the initial source bone, and the initial target The third node 403 of the bone maps to the fourth node 414 of the original source bone. Wherein, the second node 412 of the initial source bone has no mapping relationship. The second node 412 of the original source bone can be merged with its parent node, that is, merged with the first node 401 of the original source bone. Of course, any node merging in the original source skeleton will be accompanied by a merging between animation-driven materials.

在本發明一些實施例中，在將與初始源骨骼相關的第一動畫驅動資料遷移至最終目標骨骼上，得到最終目標骨骼的第二動畫驅動資料之前，需要確定最終源骨骼和最終目標骨骼之間的第一位姿變換關係。在實施時，按照從根源節點到葉源節點的順序，分別將最終源骨骼中的各源節點與最終目標骨骼中對應映射的目標節點進行對齊，以得到各源節點與映射的目標節點之間的第一位姿變換關係。如上述實施例中的描述，根節點為所在的骨骼分支數量最多的節點，則根源節點指的是最終源骨骼中的根節點。同理，根目標節點指的是最終目標骨骼的根節點。其中，葉節點指的是具有父節點但沒有子節點的節點。葉源節點指的是最終源骨骼中的葉節點，葉目標節點指的是最終目標骨骼中的葉節點。即，先對齊根源節點以及與根源節點有映射關係的根目標節點。然後再對齊與根源節點連接的葉源節點以及與該葉源節點之間具備映射關係的葉目標節點，以此類推，直至最終目標骨骼中所有節點均與最終源骨骼的節點一一對齊為止。其中，如果該源節點在目標骨骼中沒有對應的目標節點時，可以跳過該源節點，直接進行下一源節點的對齊。當然，在其他實施例中，若該源節點在目標骨骼中沒有對應的目標節點時，則將該源節點向其相鄰的父節點或子節點合併，保留該父節點或子節點的映射關係，並將合併後的源節點與對應的目標節點對齊。通過進行源節點與目標節點之間的對齊，就能夠得到各源節點與映射的目標節點之間的第一位姿變換關係，由此實現利用第一動畫驅動資料和第一位姿變換關係，得到最終目標骨骼的第二動畫驅動資料。In some embodiments of the present invention, before transferring the first animation driving data related to the initial source bone to the final target bone to obtain the second animation driving data of the final target bone, it is necessary to determine the difference between the final source bone and the final target bone. The first pose transformation relationship among them. During implementation, each source node in the final source bone is aligned with the corresponding mapped target node in the final target bone according to the order from the root node to the leaf source node, so as to obtain the distance between each source node and the mapped target node. The first pose transformation relation of . As described in the above embodiment, the root node is the node with the largest number of bone branches, and the root node refers to the root node in the final source bone. Similarly, the root target node refers to the root node of the final target bone. Wherein, a leaf node refers to a node that has a parent node but no child nodes. The leaf source node refers to the leaf node in the final source bone, and the leaf target node refers to the leaf node in the final target bone. That is, first align the root node and the root target node that has a mapping relationship with the root node. Then align the leaf source node connected to the root node and the leaf target node that has a mapping relationship with the leaf source node, and so on, until all nodes in the final target bone are aligned with the nodes of the final source bone. Wherein, if the source node does not have a corresponding target node in the target bone, the source node can be skipped and the alignment of the next source node can be performed directly. Of course, in other embodiments, if the source node does not have a corresponding target node in the target bone, the source node is merged with its adjacent parent node or child node, and the mapping relationship of the parent node or child node is retained , and align the merged source node with the corresponding target node. By aligning the source node and the target node, the first pose transformation relationship between each source node and the mapped target node can be obtained, thereby realizing the use of the first animation driving data and the first pose transformation relationship, Get the second animation driver data of the final target bone.

在本發明一些實施例中，最終源骨骼的根源節點和最終目標骨骼的根目標節點均平移至第一座標系中的原點。然後對齊最終源骨骼的根源節點和最終目標骨骼的根目標節點。在本發明一些實施例中，可以直接將最終目標骨骼的根目標節點作為第一座標系原點。第一位姿變換關係為源節點與映射的目標節點在第一座標系中的變換關係。通過最終源骨骼的根源節點和最終目標骨骼的根目標節點均平移至第一座標系的原點，能夠獲取最終源骨骼的根源節點和最終目標骨骼的根目標節點之間的偏移量。In some embodiments of the present invention, both the root node of the final source bone and the root target node of the final target bone are translated to the origin in the first coordinate system. Then align the root node of the final source bone with the root target node of the final target bone. In some embodiments of the present invention, the root target node of the final target bone can be directly used as the origin of the first coordinate system. The first pose transformation relationship is the transformation relationship between the source node and the mapped target node in the first coordinate system. By translating the root node of the final source bone and the root target node of the final target bone to the origin of the first coordinate system, the offset between the root node of the final source bone and the root target node of the final target bone can be obtained.

在本發明一些實施例中，對於最終源骨骼中的每個源節點，獲取使源節點對齊於映射的目標節點所需的偏移量。其中，偏移量包括平移分量和旋轉分量。平移分量中包括縮放分量。然後基於源節點對應的偏移量，得到源節點的第一位姿變換關係。偏移量包括平移分量和旋轉分量，使得獲取到的第一位姿變換關係更準確。其中，源節點對應的偏移量為：在源節點的第一父節點對齊且第一父節點作為第二座標系的原點的情況下，源節點與映射的目標節點在第二座標系中的偏移量。這裡出現了第一座標系以及第二座標系，因為根源節點與根目標節點已經移動至第一座標系原點，即第一座標系為以根目標節點為原點的座標系，在節點拓撲結構中，除了根源節點和根目標節點以外，所有的葉源節點和葉目標節點均有對應的父節點。並且每一葉節點最多只有一個父節點，不存在一個葉節點對應有多個父節點的情況。第二座標系即為以葉節點的父節點為座標系原點的座標系。其中，第一座標系可以看作是世界空間，第二座標系可以看作是局部空間。對於最終源骨骼中的某個節點而言，世界空間指的是以根源節點為原點的座標系，而局部空間指的是以該節點的父節點為原點的座標系。In some embodiments of the invention, for each source node in the final source bone, the offset required to align the source node to the mapped target node is obtained. Wherein, the offset includes a translation component and a rotation component. The translation component includes a scaling component. Then, based on the offset corresponding to the source node, the first pose transformation relationship of the source node is obtained. The offset includes a translation component and a rotation component, so that the obtained first pose transformation relationship is more accurate. Among them, the offset corresponding to the source node is: when the first parent node of the source node is aligned and the first parent node is the origin of the second coordinate system, the source node and the mapped target node are in the second coordinate system offset. The first coordinate system and the second coordinate system appear here, because the root node and the root target node have moved to the origin of the first coordinate system, that is, the first coordinate system is the coordinate system with the root target node as the origin, in the node topology In the structure, except the root node and root target node, all leaf source nodes and leaf target nodes have corresponding parent nodes. And each leaf node has at most one parent node, and there is no situation where a leaf node corresponds to multiple parent nodes. The second coordinate system is the coordinate system with the parent node of the leaf node as the origin of the coordinate system. Among them, the first coordinate system can be regarded as the world space, and the second coordinate system can be regarded as the local space. For a node in the final source bone, the world space refers to the coordinate system with the root node as the origin, and the local space refers to the coordinate system with the parent node of the node as the origin.

Pose transformation relationship. Based on the pose of the source node and the mapped target node in the first coordinate system, the second pose transformation relationship and the third pose transformation relationship, the offset corresponding to the source node is obtained. Among them, the pose here includes position and rotation.

基於源節點對應的偏移量，得到源節點的第一位姿變換關係。在本發明一些實施例中，基於源節點以及源節點的上級節點分別對應的偏移量，得到源節點的第一位姿變換關係。其中，源節點的上級節點為最終源骨骼中源節點的第一父節點、根源節點以及第一父節點與根源節點之間的節點。其中，偏移量均可以用矩陣表示，在本發明一些實施例中，通過將源節點以及源節點的上級節點分別對應的偏移量進行矩陣乘法，即可得到源節點的第一位姿變換關係。Based on the offset corresponding to the source node, the first pose transformation relationship of the source node is obtained. In some embodiments of the present invention, the first pose transformation relationship of the source node is obtained based on the offsets corresponding to the source node and the parent node of the source node respectively. Wherein, the parent node of the source node is the first parent node of the source node, the root node and the nodes between the first parent node and the root node in the final source bone. Wherein, the offset can be represented by a matrix. In some embodiments of the present invention, the first pose transformation of the source node can be obtained by matrix multiplication of the offsets corresponding to the source node and the source node's superior node respectively. relation.

在本發明一些實施例中，最終目標骨骼的第二動畫驅動資料是基於第一動畫驅動資料以及第一位姿變換關係得到的。如上述實施例中的描述，第一位姿變換關係為最終源骨骼的源節點與最終目標骨骼中映射的目標節點之間的變換關係。其中，最終目標骨骼為目標對象的骨骼。其中，第一動畫驅動資料是基於最終源骨骼與初始源骨骼之間的拓撲結構差異，對初始源骨骼的原始動畫資料進行調整得到的。在最終源骨骼的拓撲結構與初始源骨骼的拓撲結構一致的情況下，則與初始源骨骼相關的第一動畫驅動資料與初始源骨骼的動畫驅動資料相同。在最終源骨骼的拓撲結構與初始源骨骼不同的情況下，即源骨骼被更新過，最終源骨骼的第一動畫驅動資料則與初始源骨骼的動畫驅動資料不同。其中，最終源骨骼的第一動畫驅動資料可以根據最終源骨骼和初始源骨骼之間的拓撲結構差異確定。也就是最終源骨骼的第一動畫驅動資料可根據其拓撲結構的變化，相應的做出變化。例如，初始源骨骼的源節點A與其子節點B融合為了一個節點C，得到最終源骨骼的拓撲結構，此時，最終源骨骼中節點C的動畫資料可以是源節點A與其子節點B的動畫資料的融合。當然，在其他實施例中，若出現兩個源節點合併的情況時，還可刪除兩個源節點中的子節點的動畫驅動資料。關於得到與初始源骨骼相關的第一動畫驅動資料的方式此處不做規定。In some embodiments of the present invention, the second animation driving data of the final target bone is obtained based on the first animation driving data and the first pose transformation relationship. As described in the above embodiment, the first pose transformation relationship is the transformation relationship between the source node of the final source bone and the target node mapped in the final target bone. Wherein, the final target bone is the bone of the target object. Wherein, the first animation driving data is obtained by adjusting the original animation data of the initial source bone based on the topology difference between the final source bone and the initial source bone. In the case that the topology structure of the final source bone is consistent with that of the initial source bone, the first animation driving data related to the initial source bone is the same as the animation driving data of the initial source bone. In the case that the topology structure of the final source bone is different from that of the initial source bone, that is, the source bone has been updated, the first animation driving data of the final source bone is different from the animation driving data of the initial source bone. Wherein, the first animation driving data of the final source bone may be determined according to the topology difference between the final source bone and the initial source bone. That is, the first animation driving data of the final source bone can be changed accordingly according to the change of its topology. For example, the source node A of the initial source bone and its child node B are fused into a node C to obtain the topology of the final source bone. At this time, the animation data of node C in the final source bone can be the animation of source node A and its child node B Fusion of data. Of course, in other embodiments, if two source nodes are merged, the animation driving data of the child nodes in the two source nodes can also be deleted. The way of obtaining the first animation driving data related to the initial source skeleton is not specified here.

其中，將與初始源骨骼相關的第一動畫驅動資料遷移至最終目標骨骼上，得到最終目標骨骼的第二動畫驅動資料的方式包括：基於目標對象中的幾何網格頂點的第一位置資訊，第一動畫驅動資料以及第一位姿變換關係，得到第二動畫驅動資料中關於幾何網格頂點的第二位置資訊。其中，這裡的第一位置資訊、第一動畫驅動資料以及第一位姿變換關係可以使用矩陣表示，通過矩陣乘法就能夠得到幾何網格頂點的第二位置資訊。通過結合目標對象中的幾何網格頂點的第一位置資訊、第一動畫驅動資料以及第一位姿變換關係，就能夠得到第二動畫驅動資料中關於幾何網格頂點的第二位置資訊，過程方便。 Among them, the method of migrating the first animation driving data related to the initial source bone to the final target bone to obtain the second animation driving data of the final target bone includes: Based on the first position information of the geometric mesh vertices in the target object, the first animation driving data and the first pose transformation relationship, the second position information about the geometric mesh vertices in the second animation driving data is obtained. Wherein, the first position information, the first animation driving data and the first pose transformation relationship here can be represented by a matrix, and the second position information of the vertices of the geometric mesh can be obtained through matrix multiplication. By combining the first position information of the geometric mesh vertices in the target object, the first animation driving data and the first pose transformation relationship, the second position information about the geometric mesh vertices in the second animation driving data can be obtained. Convenience.

其中，在利用初始源骨骼相關的第一動畫驅動資料驅動最終目標骨骼運動之前，需要進行骨骼蒙皮。其中，骨骼蒙皮的常見方法很多，此處不做一一列舉。在本發明一些實施例中，當一個幾何網格頂點受到多個目標節點的影響時，需要計算各目標節點對幾何網格頂點的影響權重。其中，可以使用線性混合蒙皮方法，在標準的線性混合蒙皮中，使用創作工具為每個頂點分配了一組能夠影響頂點的目標節點對應的權重。當然，在其他實施例中也可以通過熱量平衡方法確定權重，例如將影響頂點的節點溫度設置為1，沒有影響頂點的節點溫度設置為0，然後解決網格表面的熱量平衡問題。Among them, before using the first animation driving data related to the initial source bone to drive the motion of the final target bone, it is necessary to perform bone skinning. Among them, there are many common methods of bone skinning, so I won't list them here. In some embodiments of the present invention, when a geometric grid vertex is influenced by multiple target nodes, it is necessary to calculate the influence weight of each target node on the geometric grid vertex. Among them, the linear blend skinning method can be used. In the standard linear blend skinning, authoring tools are used to assign a set of weights corresponding to target nodes that can affect the vertex to each vertex. Of course, in other embodiments, weights can also be determined by a heat balance method, for example, the temperature of nodes that affect vertices is set to 1, and the temperature of nodes that do not affect vertices is set to 0, and then solve the problem of heat balance on the mesh surface.

在本發明一些實施例中，獲取與幾何網格頂點距離滿足預設條件的至少一個目標節點作為參考節點，並獲得參考節點的影響權重。在實施時，一個頂點可能受到多個節點的影響，但是現代圖形處理器（Graphics Processing Unit，GPU）最終支援能夠影響單個頂點的節點數為4，即一個頂點最多受到4個節點的影響。其中，這四個節點的影響權重之和為1。當計算出影響頂點的參考節點數大於4時，將各影響權重進行排序，選擇最高的四個權重對應的節點作為參考節點，並重新計算這四個參考節點的影響權重，使得這四個參考節點的影響權重之和為1。In some embodiments of the present invention, at least one target node whose distance from the vertex of the geometric grid satisfies a preset condition is obtained as a reference node, and the influence weight of the reference node is obtained. In implementation, a vertex may be affected by multiple nodes, but the modern Graphics Processing Unit (GPU) finally supports 4 nodes that can affect a single vertex, that is, a vertex is affected by up to 4 nodes. Among them, the sum of the influence weights of these four nodes is 1. When it is calculated that the number of reference nodes affecting the vertices is greater than 4, sort the influence weights, select the nodes corresponding to the four highest weights as reference nodes, and recalculate the influence weights of these four reference nodes, so that the four reference nodes The sum of influence weights of nodes is 1.

其中，可以採用公式（3）解決網格表面的熱量平衡問題：

（3）；其中，如果節點i滿足預設條件的情況下，pi等於1，否則為0。

是離散表面上的拉普拉斯運算元。H是對角矩陣。其中，H一般等於c/d，c可以取值0.22或者1等，d為節點i與頂點之間的距離，H的目的是權重係數與骨骼和頂點之間的距離呈反比。通過此種方式即可得到參考節點的權重。 Among them, formula (3) can be used to solve the heat balance problem on the grid surface:

(3); Among them, if node i satisfies the preset condition, pi is equal to 1, otherwise it is 0.

is the Laplace operator on discrete surfaces. H is a diagonal matrix. Among them, H is generally equal to c/d, c can take a value of 0.22 or 1, etc., d is the distance between node i and the vertex, and the purpose of H is that the weight coefficient is inversely proportional to the distance between the bone and the vertex. In this way, the weight of the reference node can be obtained.

基於第一動畫驅動資料中關於參考節點的第四位姿變換關係和參考節點對應的第一位姿變換關係，得到參考節點對應的第五位姿變換關係。然後根據第一位姿變換關係以及源節點的第四位姿變換關係得到參考節點的第五位姿變換關係。其中，這裡的關於參考節點的第四位姿變換關係可以是動畫關鍵幀中攜帶的源骨骼各節點的變換關係。例如，可以是源節點與其父節點之間的變換關係，通過將源節點至根源節點之間所有相鄰節點之間的變換關係相乘，並結合源節點與目標節點之間的第一位姿變換關係，就能得到目標節點的第五位姿變換關係。第四位姿變換關係包括平移和/或旋轉。Based on the fourth pose transformation relation about the reference node in the first animation driving data and the first pose transformation relation corresponding to the reference node, a fifth pose transformation relation corresponding to the reference node is obtained. Then, the fifth pose transformation relation of the reference node is obtained according to the first pose transformation relation and the fourth pose transformation relation of the source node. Wherein, the fourth pose transformation relation about the reference node here may be the transformation relation of each node of the source bone carried in the animation key frame. For example, it can be the transformation relationship between the source node and its parent node, by multiplying the transformation relationship between all adjacent nodes between the source node and the root node, and combining the first pose between the source node and the target node transformation relationship, the fifth pose transformation relationship of the target node can be obtained. The fourth pose transformation relationship includes translation and/or rotation.

利用第一位置資訊，各參考節點對應的第五位姿變換關係和影響權重，得到幾何網格頂點的第二位置資訊。通過考慮參考節點對頂點的影響權重，使得獲取得到的幾何網格頂點的第二位置資訊更為準確。Using the first position information, the fifth pose transformation relationship and influence weight corresponding to each reference node, the second position information of the vertices of the geometric mesh is obtained. By considering the influence weight of the reference node on the vertex, the obtained second position information of the vertex of the geometric mesh is more accurate.

可以採用公式（4）確定幾何網格頂點的第二位置資訊V ₂：

（4）；

為參考節點j的影響權重，

為參考節點j的第五位姿變換關係，V ₁為幾何網格頂點在靜止姿勢時的第一位置資訊。 Formula (4) can be used to determine the second position information V ₂ of the vertices of the geometric grid:

(4);

is the influence weight of the reference node j,

is the fifth pose transformation relation of the reference node j, and V ₁ is the first position information of the geometric mesh vertex in the static pose.
