Abstract

By the use of moire topogarphy method, we developed a comprehensive computer-vision system (CCVS) and firstly put the system into practical industrial use to measure the surface of large 3-D objects, such as the surface of vane of hydraulic turbine. The dimensions of the vane are about 6m X 5m X 3m . In this paper, with the help of Fourier optics theoritical analysis of the forma- tion of moire fringes is given and CCVS is presented.
