Patent JP-H0755445-A (JP)
Title: Three-dimensional measuring equipment
Inventor: MATSUBA KATSUMI
IPC: G06T7/60
Filed: 1993-08-19
Abstract: PURPOSE:To take out only the outline of an object as an edge regardless of noise, e.g. characters and patterns printed on the surface of an object. CONSTITUTION:CCD cameras 1R, 1L pick up stereoscopic images to obtain an edge image while furthermore pick up the images when a pattern light is projected from a pattern light projector 2 thus obtaining a binary image. The point of inflection Pc and the end point Pe on the border line of the binary image do not exist on the outline of a character 'T' printed on the upper face of a corrugated cardboard case W but exist only on the outline of the corrugated cardboard case W. Consequently, when the point of inflection Pc and the end point Pe are superposed on the edge image and only such edge as the points exist is extracted, the three-dimensional shape can be recognized easily and accurately.
