Using mesh projection and sub-pixel technology, the three-dimensional shape of the automatic grid method is successfully measured. A new grid point segmentation method—the whole-field threshold function method—is proposed to speed up the segmentation speed and improve segmentation quality. In addition, a new method of searching and coding using the adjacent position relation of meshes is also proposed, which solves the problem of automatic coding and matching of mesh lattices with large deformation or null defects. Through the actual measurement research on the standard slant and cylindrical surface, it is verified that the automatic mesh shape test method can perform high-precision measurement quickly and automatically. Some experimental results are given in the article
