Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
In order to at least solve the technical problem proposed in the present invention, an embodiment of the present invention provides a method for displaying a picture in 3D based on a mobile terminal.
Fig. 1 is a schematic flow chart of a method for displaying a picture in 3D based on a mobile terminal according to an embodiment of the present invention, as shown in fig. 1, the method according to the embodiment of the present invention may include the following steps:
and S11, acquiring a target picture set, wherein the target picture set comprises a plurality of target pictures.
In a specific implementation process, any one of the mobile terminals may be defined as a mobile terminal for 3D image display, and the mobile terminal performs 3D display.
For example, the target picture set may be acquired by the mobile terminal, for example, the target picture may be directly photographed by the mobile terminal, so that the server obtains the target picture by photographing of the mobile terminal; or uploading the stored target picture to the server through the mobile terminal.
In some embodiments, optionally, acquiring the target picture set includes: acquiring a multi-angle target picture according to the main body identification; and adjusting the sequence of the target pictures according to the preset picture sequence to obtain a target picture set.
For example, when a target picture set is obtained, multi-angle target pictures can be obtained, and the target picture set is obtained by adjusting the sequence of the target pictures according to a preset picture sequence. If 3D modeling needs to be carried out on one cup, target pictures of the cup can be taken from different angles, wherein the cup in the target pictures is a main element. When the target picture of the cup is obtained, a front view, a top view, a rear view, a side view and the like of the cup can be respectively obtained, the picture is obtained from different angles to serve as the target picture, and the sequence of the target picture is adjusted according to the preset sequence of the front view, the right view, the rear view and the left view.
When the target picture is obtained, the mobile terminal can display the main body identification when the picture is shot, and the target picture is shot through the main body identification. For example, the subject identifier may be an outer frame in a preset shape, such as a virtual rectangular frame, and when shooting is performed, the content in the virtual rectangular frame is a subject picture by default.
The virtual rectangular frame can be a virtual rectangular frame when a picture is shot, or a virtual rectangular frame manually set by a user through a mobile terminal, for example, after a target picture is displayed, the virtual rectangular frame is displayed on the target picture, the user adjusts the position of the virtual rectangular frame according to requirements, and a main element is placed in the virtual rectangular frame, so that the final position of the virtual rectangular frame is determined.
For example, in order to ensure the accuracy of the target picture, when taking the picture, a cup may be placed as a main element in a default virtual rectangular frame to obtain the target picture set.
And S12, acquiring the main body picture in the target picture through the main body identification of the target picture.
For example, the virtual rectangular frame may be directly used as the subject identifier, the content inside the virtual rectangular frame may be used as the subject picture in the target picture, and the content outside the virtual rectangular frame may be used as the background picture in the target picture.
When the main body picture is obtained, each target picture can be processed one by one in a queue mode, and each target picture and the corresponding virtual rectangular frame are read to obtain the corresponding main body picture.
In some embodiments, optionally, obtaining the subject picture in the target picture through the subject identifier of the target picture includes:
determining a preliminary main body picture in the target picture according to the main body identification of the target picture;
and marking the target subject picture in the preliminary subject picture according to the pixel similarity in the preliminary subject picture.
For example, after the target picture is acquired, part of the subject identifier may be used as a preliminary subject picture according to the subject identifier of the target picture, that is, a preliminary matting function is implemented. And on the basis of the primary subject picture, acquiring a target subject picture in the primary subject picture according to the pixel similarity.
In some embodiments, optionally, the method further includes: determining a boundary line between the target main body picture and the target background picture according to the pixel similarity in the primary main body picture, and marking the target main body pixel and the target background pixel; and if the unmarked pixels exist in the preliminary target picture, enlarging the range of the boundary line, marking the unmarked pixels and obtaining the target main picture.
For example, a cup is still used as a main element for explanation. Firstly, roughly dividing a target picture according to a virtual rectangular frame to obtain a roughly divided primary target picture; after the preliminary target picture is obtained, according to the similarity of the pixels, a boundary line between the target main picture and the target background picture is determined, and the target main pixel and the target background pixel are marked. For example, each pixel of the picture may be marked as a main pixel or a background pixel based on the similarity of the color gamut of the pixel and the surrounding pixels, and if there are still undefined pixels, the range of the surrounding pixels is expanded, so as to determine a boundary line belonging to the main picture and the background picture, and then the content of the target main picture is extracted, and the target background picture is emptied and output as a png format picture as the target main picture.
For example, when the boundary line is identified according to the color gamut, the color gamut key of the main element may be determined according to the color gamut in the preliminary target image, so as to calculate the similarity between the pixels of the key color gamut and the peripheral pixels, and if the similarity is lower than the threshold, the pixels with the similarity lower than the threshold are the background pixels, and the pixels with the similarity greater than or equal to the threshold are the main pixels. And when the undefined pixel still exists, expanding the range of the peripheral pixels so as to carry out large-range pixel similarity calculation, defining the undefined pixel, distinguishing the undefined pixel from the main pixel or the background pixel so as to determine a final boundary line.
And S13, inserting each main picture into a preset virtual ring according to a preset sequence to form a virtual ring body so as to determine a composite picture, and recording the position information of each main picture.
In some embodiments, optionally, the location information includes: the position and insertion angle of the subject picture relative to the virtual ring.
For example, after the main body picture of each target picture is acquired, each main body picture may be inserted into a preset virtual ring according to the direction of the main body element in each main body picture, so that the main body pictures form a virtual ring, the whole virtual ring is used as a composite image, and the position information of each main body picture in the virtual ring is recorded. For example, when a subject picture is inserted into a virtual ring, the virtual ring may be divided equally, the subject picture may be inserted into the virtual ring according to the shooting angle of each subject picture, and the position and angle information of each subject picture with respect to the virtual ring at that time may be recorded.
And S14, receiving the display request, sending the main body picture and the position information to the mobile terminal so that the mobile terminal forms a target composite picture, rendering the target composite picture, and displaying the 3D picture on the main body.
For example, the mobile terminal may send a presentation request to the server, and after receiving the presentation request, the server sends all the recorded main body pictures of each main body element and the position information of each main body picture to the mobile terminal. And the mobile terminal acquires all main body pictures of the main body element and the position information of each main body picture, inserts all the main body pictures into the corresponding positions of the ring in the canvas according to the position information, and renders the main body pictures so as to complete the 3D modeling of the main body element.
When all the main body pictures are subjected to network requests and loading, all the pictures are inserted into corresponding annular positions in a canvas according to the position information, the gesture events are monitored, and left-right rotation of main body elements is executed according to different gesture actions, so that a 3D effect is achieved.
According to the method for displaying the picture in the 3D mode based on the mobile terminal, the target picture set is obtained, and the target picture set comprises a plurality of target pictures; acquiring a main body picture in the target picture through the main body identification of the target picture; inserting each main body picture into a preset virtual ring according to a preset sequence to form a virtual ring body so as to determine a composite picture, and recording the position information of each main body picture; and receiving a display request, and sending the main body picture and the position information to the mobile terminal so that the mobile terminal forms a target composite picture, renders the target composite picture, and displays the 3D picture on the main body. Through the processing of the target picture, the main elements in the target picture are obtained and spliced, so that automatic 3D modeling and 3D effect display are achieved, convenience and rapidness are achieved, and timeliness is improved.
