Numerical Simulation Check-up of Automated Grid Program
Bai Shi-wei · Zhanjiang Haiyang Daxue xuebao · 2003
In order to checkup program, original grid image and deformation grid image are made by computer. The rigid body move, the rigid body turn and the common deformation are considered in making deformation grid image, and the big deformation grid image lack in a few points is also made. The results indicate: in cases of different deformations, especially in case of big deformation grid image lack in a few points, although points in grid image are irregular, program can segment and encode automatically and accurately; the error of points with two-digit distribution is under 0. 005 8 pixel , and the error of points with GAUSS distribution is under 0.000 76 pixel.
