determining a three-dimensional selected region 400 in the three-dimensional image, determining and displaying a two-dimensional selected region in a two-dimensional image corresponding to the three-dimensional image based on the three-dimensional selected region 400, generating target map data based at least on the size of the two-dimensional selected region, replacing the image data of the two-dimensional selected region in the two-dimensional image with the target map data, generating a mapped two-dimensional image 407, and converting the mapped two-dimensional image 407 into a mapped three-dimensional image 408.
In step S201, the platform may acquire an image, and acquire, according to a user operation, a selected area selected by a user on the image by using an input device, where the image may be loaded on a terminal device based on a user selection, or may be directly uploaded by the user, and a dimension of the selected area is the same as that of the image.

Further, the user may select the selected area by painting or dragging the input device to define.
As shown in step S202, since the dimension of the selected area is the same as the dimension of the image, the selected area is a three-dimensional image, and the direct mapping results in mismatching of the mapping position and the model and failure to attach to the correct position in consideration of the possible occurrence of irregular shape of the three-dimensional image.

In order to facilitate the subsequent generation of the target map 405, the size of the target map 405 may be greater than or equal to the image size of the two-dimensional selected area, which prevents the number of pixels from being affected during the subsequent amplification process due to the target map 405 being too small, reduces the resolution, and increases the difficulty of post-rendering.
Further, as shown in step S204, the target map data may further include image data, the two-dimensional selected region image data is replaced with image data of the target map 405, a mapped target image is generated, and the mapped target image is converted into a three-dimensional image.

The user can select the patches within the range of the three-dimensional graph 401, wherein the patches can be triangular patches or quadrilateral patches, and the user can select the patches according to actual conditions without limitation. And according to the seam of the three-dimensional image, expanding the image to obtain a two-dimensional image.
Further, as shown in step S303, an initial two-dimensional image 403 is acquired from the three-dimensional selected region 400. In order to present the user-selected region in real-time, the platform may generate a selected region presentation image 402 corresponding to the initial two-dimensional image 403, as shown in step S304. The selected region presentation image 402 is presented by the user terminal. Wherein the texture and/or color of the selected region presentation image 402 is different from the initial two-dimensional image 403 for convenience of the user to distinguish the selected region presentation image 402 from the initial two-dimensional image 403.
As shown in step S305, a mask image 404 of the same size may be generated from the initial two-dimensional image 403. Wherein the mask image 404 may be used to hide or display portions of the image layer. The first color display may correspond to a region of the two-dimensional selected region, and the other regions may be displayed with a second color, where the first color is different from the second color for distinguishing different transparency. The specific colors of the first color and the second color are not limited herein, and the first color may be white or black, and may be selected by the user according to actual situations.
Fig. 4 is a schematic diagram illustrating a mask generating process of applying a mapping method of a three-dimensional image according to an embodiment of the present disclosure, and as shown in fig. 4, taking a user selecting a patch within a range of a three-dimensional graphic 401 as a triangle patch as an example, specific steps of generating a mask image 404 may include: traversing the triangle patch to obtain the triangle patch of the three-dimensional selected area 400.

And filling the area surrounded by the A1, the B1 and the C1 with a first color.

The mask image 404 and the selected region presentation image 402 may be superimposed, where the superimposed presentation image is superimposed to the initial two-dimensional image 403.
Generating target map data based at least on the size of the two-dimensional selected region, comprising: a minimum bounding rectangle 406 of the two-dimensional selected region is determined, and target map data is generated having the same aspect ratio as the minimum bounding rectangle 406.
Further, as shown in step S307, the specific step of generating target map data may include: a minimum bounding rectangle of the first color region of the mask image 404 is calculated. The minimum bounding rectangle refers to the maximum range of a plurality of two-dimensional shapes (such as points, straight lines and polygons) expressed by two-dimensional coordinates, namely, the rectangle with the lower boundary defined by the maximum abscissa, the minimum abscissa, the maximum ordinate and the minimum ordinate of each vertex of the given two-dimensional shape.

Target map data having the same aspect ratio as the minimum bounding rectangle 406 is obtained from the target image based on the minimum bounding rectangle size information. The target image data is preferably greater than or equal to the minimum bounding rectangle, and if the target image data is too small, the user's margin for positional adjustment of the target image at a later stage is too small. And when the user adjusts the target image to be attached to the selected area image, the size of the target image needs to be changed, so that the pixels of the target image are changed, and the later rendering difficulty is increased.

In the above, the mapping method of the three-dimensional image according to the embodiment of the present disclosure is described, and the mapping generation apparatus 600 for implementing the mapping method of the three-dimensional image will be further depicted below the patch within the range where the user can select the three-dimensional image 401.

Wherein the texture and/or color of the selected region presentation image 402 is different from the initial two-dimensional image 403 for convenience of the user to distinguish the selected region presentation image 402 from the initial two-dimensional image 403.
Further, a mask image 404 of the same size may be generated from the initial two-dimensional image 403. Wherein the mask image 404 may be used to hide or display portions of the image layer. The first color display may correspond to a region of the two-dimensional selected region, and the other regions may be displayed with a second color, where the first color is different from the second color for distinguishing different transparency. The specific colors of the first color and the second color are not limited herein, and the first color may be white or black, and may be selected by the user according to actual situations.
Taking a user selecting a patch within the three-dimensional graphic 401 as a triangle patch as an example, the specific steps of generating the mask image 404 may include: traversing the triangle patch to obtain the triangle patch of the three-dimensional selected area 400. For the current triangle patch ABC, the triangle area A1B1C1 corresponding to the mask image 404 is searched, and coordinates of A1, B1 and C1 are obtained. And filling the area surrounded by the A1, the B1 and the C1 with a first color.
