Abstract

In this paper, two methods are presented to measure 3D shape of red-hot ingot by visions. In the first method, contour analysis is used and a rather simple measuring system is configured. In the second method, the slit-ray projection is employed and the problem of fluctuation caused by gravity of target ingot is strongly considered. A technique of curve fitting is developed for reconstruction of cross-sections. Experiments show that both of contour analysis and slit-ray projection are applicable.
