設計業，特別是工業設計(ID, Industrial Design)部門在設計出例如為電子產品、生活用品、建築、機械機構實物等，為求設計稿件與設計實品能盡量相符，通常在完成設計稿件後，設計者會將此設計稿件等比例印出，做為實品大小及顏色的確認，更方便提供部門進行設計稿件的續行討論。若設計案的物件實品比例過大，例如為車體，則會以印表機個別印出此設計稿件的各個部位，再進行拼貼。The design industry, especially the industrial design (ID, Industrial Design) department, is designing physical objects such as electronic products, daily necessities, buildings, and mechanical structures.

以上之關於本揭露內容之說明及以下之實施方式之說明係用以示範與解釋本發明之精神與原理，並且提供本發明之專利申請範圍更進一步之解釋。The above description of the disclosure and the following description of the embodiments are used to demonstrate and explain the spirit and principle of the present invention, and to provide a further explanation of the scope of the patent application of the present invention.

以下在實施方式中詳細敘述本發明之詳細特徵以及優點，其內容足以使任何熟習相關技藝者了解本發明之技術內容並據以實施，且根據本說明書所揭露之內容、申請專利範圍及圖式，任何熟習相關技藝者可輕易地理解本發明相關之目的及優點。以下之實施例係進一步詳細說明本發明之觀點，但非以任何觀點限制本發明之範疇。The detailed features and advantages of the present invention will be described in detail in the following embodiments. The content is sufficient to enable anyone familiar with the relevant art to understand the technical content of the present invention and implement it accordingly, and according to the content disclosed in this specification, the scope of patent application and the drawings. Anyone who is familiar with relevant skills can easily understand the purpose and advantages of the present invention. The following examples further illustrate the viewpoints of the present invention in detail, but do not limit the scope of the present invention by any viewpoint.

請參考圖1。本發明第一實施例的等比例投影方法適用於一等比例投影裝置，而此等比例投影裝置係包含：深度感測組件1、電子裝置2、投影組件3及照相組件4，其中電子裝置2電性連接深度感測組件1、投影組件3及照相組件4。雖然本發明第一實施例的等比例投影方法係以本等比例投影裝置來實現，然照相組件4主要係用於驗證投影組件3所投放出的畫面是否確呈等比例，因此等比例投影裝置亦可不包含照相組件4，並由等比例投影方法中省略此驗證部分。Please refer to Figure 1. The isometric projection method of the first embodiment of the present invention is applicable to a isometric projection device, and the isometric projection device includes: a depth sensing component 1, an electronic device 2, a projection component 3, and a camera component 4, wherein the electronic device 2 The depth sensing component 1, the projection component 3 and the camera component 4 are electrically connected. Although the isometric projection method of the first embodiment of the present invention is implemented by this isometric projection device, the camera assembly 4 is mainly used to verify whether the image projected by the projection assembly 3 is indeed of the same proportion. Therefore, the isometric projection device The camera assembly 4 may not be included, and the verification part is omitted from the isometric projection method.

深度感測組件1用於感測深度感測組件1與投影面PS的距離並據以產生及輸出一距離資訊。深度感測組件1可利用各種深度感測技術以感測距離，如飛時測距(ToF：Time of Flight)、結構光(Structured light)等。由於本實施例裡投影面PS為一平面，故深度感測組件1只用於感測其與投影面PS之距離L。然深度感測組件1亦可感測曲面，使得在投影面PS為曲面時，等比例投影裝置在經運算後對該曲面投射出對人眼視覺而言為平坦的等比畫面，本發明不於此作限制。深度感測組件1在感測出距離L後，據以產生及傳送一距離資訊至電子裝置2。The depth sensing component 1 is used for sensing the distance between the depth sensing component 1 and the projection surface PS and generating and outputting distance information accordingly. The depth sensing component 1 can use various depth sensing technologies to sense distance, such as Time of Flight (ToF), structured light (Structured light), and so on. Since the projection surface PS is a flat surface in this embodiment, the depth sensing component 1 is only used to sense the distance L between it and the projection surface PS. However, the depth sensing component 1 can also sense a curved surface, so that when the projection surface PS is a curved surface, the proportional projection device projects a proportional image that is flat for human vision on the curved surface after calculation. The present invention does not Limit it here. After the depth sensing component 1 senses the distance L, it generates and transmits distance information to the electronic device 2 accordingly.

電子裝置2在接收該距離資訊後，至少依據該距離資訊及一投影參數資訊產生並傳送一等比畫面資訊至該投影組件。請參考圖1。電子裝置2具有關聯於投影組件3的該投影參數資訊，該投影參數資訊可具有預先測得的投影組件3的投射角度資訊，或者該投影參數資訊也可具有預先測得的在原距離L 0下投影組件3投射之原投影畫面長PPL 0。然而，該投影參數資訊可不只限於上述任一種，亦可同時具有前述兩者或更多，本發明不限於此。關於該等比畫面資訊於下方流程段落會再詳加說明。 After receiving the distance information, the electronic device 2 generates and transmits a proportional image information to the projection component at least according to the distance information and a projection parameter information. Please refer to Figure 1. The electronic device 2 has the projection parameter information associated with the projection component 3. The projection parameter information can have the projection angle information of the projection component 3 measured in advance, or the projection parameter information can also have the projection angle information measured in advance at the original distance L 0 The length of the original projection screen projected by the projection component 3 is PPL 0 . However, the projection parameter information may not be limited to any one of the foregoing, and may have two or more of the foregoing at the same time, and the present invention is not limited to this. The information about these comparison screens will be explained in detail in the following process paragraphs.

投影組件3用於接收該等比畫面資訊後，投射一等比畫面PP至投影面PS。投影面PS可為平坦的牆面，或是設立好的投影幕，用於呈現投射出的等比畫面PP。投影組件3在接收該等比畫面資訊後，據以輸出等比畫面PP。投影組件3可置於深度感測組件1的一側，其中投影組件3的光軸與深度感測組件1的光軸可互相平行，且兩組件的鏡頭較佳係切齊於一平面。The projection component 3 is used for receiving the ratio picture information and projecting a ratio picture PP to the projection surface PS. The projection surface PS can be a flat wall or a well-established projection screen for presenting the projected proportional picture PP. After the projection component 3 receives the ratio picture information, it outputs the ratio picture PP accordingly. The projection assembly 3 may be placed on one side of the depth sensing assembly 1, wherein the optical axis of the projection assembly 3 and the optical axis of the depth sensing assembly 1 may be parallel to each other, and the lenses of the two assemblies are preferably aligned on a plane.

照相組件4用於拍攝含有等比畫面PP的投影面PS並據以產生及輸出一實際畫面資訊。照相組件4可置於深度感測組件1的一側，其中深度感測組件1的光軸與照相組件4的光軸可互相平行，且兩組件的鏡頭較佳係切齊於一平面。照相組件4拍攝一畫面，該畫面內需包含含有等比畫面PP的投影面PS。取得該畫面後，照相組件4據以產生及傳送一實際畫面資訊至電子裝置2，以供電子裝置2依據此實際畫面資訊判斷應否進一步調校等比畫面PP。請同時參照圖2，圖2為照相組件4取得之該畫面示意圖，其中最外方框為該畫面的邊界，為聚焦於照相組件4的設置目的，後續流程僅以該畫面內的等比畫面PP作討論。其中經由照相組件4拍攝，由該實際畫面資訊可得知等比畫面PP具有設計稿件的物件O。The photographing component 4 is used for photographing the projection surface PS containing the proportional picture PP and generating and outputting actual picture information accordingly. The camera assembly 4 can be placed on one side of the depth sensing assembly 1, wherein the optical axis of the depth sensing assembly 1 and the optical axis of the camera assembly 4 can be parallel to each other, and the lenses of the two assemblies are preferably aligned on a plane. The camera assembly 4 takes a picture, and the picture needs to include a projection surface PS containing a proportional picture PP. After obtaining the frame, the camera assembly 4 generates and transmits an actual frame information to the electronic device 2 for the electronic device 2 to determine whether the proportional frame PP should be further adjusted based on the actual frame information. Please refer to Figure 2 at the same time. Figure 2 is a schematic diagram of the picture obtained by the camera assembly 4, in which the outermost frame is the border of the picture. For the purpose of focusing on the setting of the camera assembly 4, the subsequent process only uses the proportional picture in the picture PP for discussion. Among them, it is photographed by the camera assembly 4, and from the actual screen information, it can be known that the proportional screen PP has the object O of the design document.

電子裝置2接收到該實際畫面資訊後，再依據該實際畫面資訊對該等比畫面資訊進行一畫面校正程序。該畫面校正程序可為關聯於該等比畫面PP色溫的校正；若電子裝置2內預存關聯於照相組件4的照相參數資訊，如圖3，則該畫面校正程序亦可為等比畫面PP中物件長OL的校正。關於該畫面校正程序在下方流程段落會再詳加說明。After receiving the actual screen information, the electronic device 2 performs a screen calibration process on the comparison screen information according to the actual screen information. The screen calibration procedure can be the calibration related to the color temperature of the ratio screen PP; if the photographic parameter information related to the camera assembly 4 is pre-stored in the electronic device 2, as shown in Figure 3, the screen calibration procedure can also be in the ratio screen PP The correction of the long OL of the object. The screen correction procedure will be explained in detail in the flow paragraph below.

請參考圖4，圖4為本發明第一實施例的等比例投影方法的流程圖。請參考步驟S1，深度感測組件1感測深度感測組件1與投影面PS的距離並據以產生及傳送該距離資訊至電子裝置2。Please refer to FIG. 4, which is a flowchart of the isometric projection method according to the first embodiment of the present invention. Please refer to step S1. The depth sensing component 1 senses the distance between the depth sensing component 1 and the projection surface PS, and generates and transmits the distance information to the electronic device 2 accordingly.

請參考步驟S2，電子裝置2至少依據該距離資訊及該投影參數資訊產生及傳送該等比畫面資訊至投影組件3。有了前述步驟取得之資訊，電子裝置2可以據以求得等比畫面長PPL，並同時參照儲存於電子裝置2的該設計稿件內物件O的實際尺寸資料，以決定如何縮放物件長OL。請同時參考圖1。若該預存資料具有預先測得的投影組件3的投射角度資訊，則可以此投影參數資訊預算出等比畫面長PPL。如圖1所示，投射角A包含於該投射角度資訊，在投影組件3固定投射角度下，以投射邊緣的左投射線BL及右投射線BR夾出的角度即為投射角A。利用投射角A及深度感測組件1感測的距離L，依據三角函數即可得出等比畫面長PPL：

Figure 02_image001
Please refer to step S2. The electronic device 2 generates and transmits the ratio image information to the projection assembly 3 at least according to the distance information and the projection parameter information. With the information obtained in the foregoing steps, the electronic device 2 can obtain the proportional screen length PPL accordingly, and at the same time refer to the actual size data of the object O in the design document stored in the electronic device 2 to determine how to scale the object length OL. Please also refer to Figure 1. If the pre-stored data has the projection angle information of the projection assembly 3 measured in advance, the projection parameter information can be used to estimate the PPL equal to the screen length. As shown in FIG. 1, the projection angle A is included in the projection angle information. Under the fixed projection angle of the projection assembly 3, the angle between the left projection line BL and the right projection line BR of the projection edge is the projection angle A. Using the projection angle A and the distance L sensed by the depth sensing component 1, according to the trigonometric function, the proportional picture length PPL can be obtained:
Figure 02_image001

若該預存資料具有預先測得的在原距離L 0下投影組件3投射之原投影畫面長PPL 0，電子裝置2可依據該預存資料原距離L 0與原投影畫面長PPL 0的比例，與深度感測組件1取得之距離L，以相似三角形邊長比運算出等比畫面長PPL：

Figure 02_image003
If the pre-stored data has the pre-measured original projection screen length PPL 0 projected by the projection assembly 3 at the original distance L 0 , the electronic device 2 can calculate the depth according to the ratio of the pre-stored data’s original distance L 0 to the original projection screen length PPL 0 The distance L obtained by the sensing component 1 is calculated using the ratio of the side lengths of the similar triangles to calculate the proportional picture length PPL:
Figure 02_image003

得出等比畫面長PPL後，電子裝置2再依據物件O實際尺寸資料與等比畫面長PPL的長度比例判斷物件長OL的縮放程度，並據以產生並傳送一等比畫面資訊至投影組件3。舉例來說，若求得之等比畫面長PPL為200公分，而物件O實際邊長長度為100公分，則需要在等比畫面將物件長OL定為此時等比畫面長PPL的一半。其中該等比畫面資訊具有等比例的物件O的畫面。After obtaining the proportional screen length PPL, the electronic device 2 then judges the zoom level of the object length OL based on the actual size data of the object O and the length ratio of the proportional screen length PPL, and generates and transmits a proportional screen information to the projection component accordingly. 3. For example, if the obtained proportional screen length PPL is 200 cm, and the actual side length of the object O is 100 cm, then the object length OL needs to be set to half of the proportional screen length PPL at this time in the proportional screen. Among them, the screen information has the same proportion of the object O's screen.

請參考步驟S3，投影組件3接收等比畫面資訊後，據以投射等比畫面PP至投影面PS。舉例來說，設計稿件內的物件O實際尺寸資料為邊長50公分之正方體，則無論投影組件3與投影面PS之距離L為何，投影組件3投射出的該等比畫面內物件O在投影面PS上的邊長長度即為50公分。Please refer to step S3. After the projection component 3 receives the proportional image information, it projects the proportional image PP to the projection surface PS accordingly. For example, if the actual size data of the object O in the design manuscript is a cube with a side length of 50 cm, regardless of the distance L between the projection component 3 and the projection surface PS, the projection component 3 projected more than the object O in the screen. The length of the side on the surface PS is 50 cm.

請同時參考步驟S4及圖2，照相組件4拍攝含有該等比畫面PP的投影面PS，並據以產生及傳送一實際畫面資訊至電子裝置2。Please refer to step S4 and FIG. 2 at the same time, the camera assembly 4 photographs the projection surface PS containing the ratio pictures PP, and generates and transmits an actual picture information to the electronic device 2 accordingly.

請參考步驟S5，電子裝置2依據該實際畫面資訊對等比畫面PP進行一畫面校正程序。該畫面校正程序可為關於該等比畫面色溫的校正。該實際畫面資訊除了含有等比畫面PP及等比畫面PP內的物件O，更具有等比畫面PP的一色溫資訊。在照相組件4拍攝含有等比畫面PP的投影面PS並據以產生成該實際畫面資訊時，由於該實際畫面資訊為一數位資訊，在該實際畫面資訊被傳送至電子裝置2時，電子裝置2可辨別出該畫面內的等比畫面PP之物件O的顏色色溫、色碼等資訊。電子裝置2依據該色溫資訊辨識出物件O於等比畫面PP上之顏色色溫是否符合原設計稿件內的色溫，若否則對該等比畫面資訊進行色溫上的調整。Please refer to step S5. The electronic device 2 performs a picture correction procedure on the ratio picture PP according to the actual picture information. The screen calibration procedure can be related to the calibration of the specific screen color temperatures. The actual picture information not only includes the proportional picture PP and the object O in the proportional picture PP, but also has a color temperature information of the proportional picture PP. When the camera assembly 4 photographs the projection surface PS containing the proportional picture PP and generates the actual picture information accordingly, since the actual picture information is digital information, when the actual picture information is transmitted to the electronic device 2, the electronic device 2 The color temperature, color code and other information of the object O of the proportional screen PP in the screen can be distinguished. The electronic device 2 recognizes whether the color temperature of the object O on the proportional screen PP matches the color temperature in the original design document according to the color temperature information, and if otherwise, adjusts the color temperature of the proportional screen information.

該畫面校正程序亦可為關於該等比畫面PP中物件長OL的校正。請同時參考圖3，若電子裝置2內預存關聯於照相組件4的照相參數資訊，如在距離投影面PS原距離L 0下拍攝到的原投影畫面長PPL 0，且照相組件4的光軸與深度感測組件的光軸1各互相平行且兩鏡頭對齊於一平面，電子裝置2更可再依據上述參數及該距離資訊，以相似三角形邊長比運算出等比畫面長PPL。電子裝置2再辨識該實際畫面資訊內等比畫面長PPL與物件長OL的比例，利用甫算出的等比畫面長PPL換算出該實際畫面資訊內的物件長OL。最後電子裝置2再比對此物件長OL與設計稿件內物件O實際尺寸資料是否一致，做進一步的確認當前等比畫面是否呈現有誤。若否則需對該等比畫面資訊再進行調整。舉例來說，若經該照相參數資訊及該距離資訊求得在當前距離L下拍攝得出的等比畫面長PPL為6公尺，且電子裝置2辨識該實際畫面資訊內等比畫面長PPL與物件長OL之比例為3：2，則當前拍攝之物件長OL為4公尺。若物件O實際尺寸資料之長度為3.5，即表示等比畫面PP呈現有誤，則需以電子裝置2再對等比畫面PP進行調整。總體來說，該畫面校正程序亦可為上述色溫校正與物件長OL校正一同實施。 The screen calibration procedure can also be related to the calibration of the objects that are longer than the objects in the screen PP by OL. Please refer to FIG. 3 at the same time. If the photographic parameter information associated with the camera assembly 4 is pre-stored in the electronic device 2, for example, the original projection picture taken at the original distance L 0 from the projection surface PS is PPL 0 , and the optical axis of the camera assembly 4 The optical axis 1 of the depth sensing component is parallel to each other and the two lenses are aligned on a plane. The electronic device 2 can then calculate the PPL of the equivalent screen length based on the above-mentioned parameters and the distance information using the ratio of the side lengths of the similar triangles. The electronic device 2 then recognizes the ratio of the proportional screen length PPL to the object length OL in the actual screen information, and uses the just calculated proportional screen length PPL to convert the object length OL in the actual screen information. Finally, the electronic device 2 compares whether the length OL of the object is consistent with the actual size data of the object O in the design manuscript, and further confirms whether the current scale screen is displayed incorrectly. If otherwise, the screen information needs to be adjusted. For example, if the photographic parameter information and the distance information are used to determine that the ratio picture length PPL obtained by shooting at the current distance L is 6 meters, and the electronic device 2 recognizes the ratio picture length PPL in the actual picture information The ratio to the length OL of the object is 3:2, and the length OL of the object currently shot is 4 meters. If the length of the actual size data of the object O is 3.5, it means that the proportional screen PP is presented incorrectly, and the electronic device 2 needs to adjust the proportional screen PP again. In general, the image correction procedure can also be implemented together with the aforementioned color temperature correction and object length OL correction.

而當使用者改變電子裝置2內的物件，或是本實施例的等比例投影裝置與投影面PS之距離被改變。本實施例的等比例投影方法仍可對該等比畫面繼續進行等比例校正。When the user changes the object in the electronic device 2, or the distance between the isometric projection device of this embodiment and the projection surface PS is changed. The equal-ratio projection method of this embodiment can still perform equal-ratio correction on the equal-ratio pictures.

請參考圖5。相比於第一實施例的等比例投影裝置，本發明第二實施例的等比例投影裝置更包含訊號集中器5，此時電子裝置2係透過訊號集中器5電性連接深度感測組件1、投影組件3及照相組件4。包含訊號集中器5的好處在於若電子裝置2為可攜帶式的電子裝置，則電子裝置2只需與訊號集中器5解除連接即可取出攜帶，使其更具便利性。第二實施例與第一實施例相比只在於額外包含訊號集中器5，其運作方法第一實施例無二致，故不在此贅述。Please refer to Figure 5. Compared with the isometric projection device of the first embodiment, the isometric projection device of the second embodiment of the present invention further includes a signal concentrator 5. In this case, the electronic device 2 is electrically connected to the depth sensing component 1 through the signal concentrator 5 , Projection component 3 and camera component 4. The advantage of including the signal concentrator 5 is that if the electronic device 2 is a portable electronic device, the electronic device 2 only needs to be disconnected from the signal concentrator 5 to be taken out and carried, which makes it more convenient. Compared with the first embodiment, the second embodiment only additionally includes a signal concentrator 5, and its operation method is the same as that of the first embodiment, so it will not be repeated here.
