Problems solved by technology

[0004] At present, the 3D models generated by these methods cannot be directly applied to mobile terminals. The main problem is that there are too many triangles that make up the 3D model, which will put a huge computational pressure on mobile terminals or low-end computers.
It is difficult to specify the skeletal system for this 3D model and assign bone weights finely
The texture coordinates of the 3D model are not uniform, and it is difficult to superimpose the multi-channel texture of the 3D model
Therefore, the addition of functions or components such as movements, expressions, editing, makeup, clothing, and accessories of the 3D human model is limited.

Abstract

The present invention relates to the technical field of computer vision, and relates to a method and system for orderly transformation of a disordered 3D model. The method for orderly transformation of a disordered 3D model includes: obtaining a disordered model and a prefabricated model, and the prefabricated model is prefabricated There is a skeletal system; deform the prefabricated model according to the unordered model; obtain a new texture map according to the deformed prefabricated model and the unordered model, and move the bones of the prefabricated model to a new position. Through the orderly conversion method and system of the disordered 3D model described in the present invention, the utilization rate of the three-dimensional model can be improved.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method and system for orderly transforming disordered 3D models. Background technique [0002] In the prior art, there are many methods for creating 3D human body models, such as 3D scanning equipment, deep-sensing cameras, structured light cameras, solving the spatial position of multi-angle photos of the same human body and generating 3D models, and artificial intelligence speculation of single-angle photos A space solver solution for generating 3D models. [0003] If the 3D human body model is generated each time, the distribution of the 3D grid structure is different, or the point numbers of the 3D grid points are different, or the texture coordinate system of the 3D grid is different, or the number of 3D model grids is too high, it may become disordered. 3D human body model. [0004] At present, the 3D models generated by these methods cannot be directly applied ...
