Three-dimensional photorealistic reconstruction method and system for objects and electronic device

The invention belongs to the application field of the computer vision technology, and provides a three-dimensional photorealistic reconstruction method and system for objects and an electronic device. In the method and the system, steps are as follows: after establishing a three-dimensional texture model, using a Markov algorithm to split the three-dimensional texture model to obtain an optimal split method with minimum texture seams between different regions; then processing edge triangles of different regions to achieve the purpose of eliminating the texture seams to reconstruct the photorealistic three-dimensional model of the object. With respect to a conventional method which directly processes the edge triangles after establishing the three-dimensional texture model or processes the textures of overlapped regions to realize texture fusion, the method provided by the invention can more effectively eliminate the texture seams, and realize smooth and natural transition between different image regions in the three-dimensional texture model with a better blending effect.
