Development of a System for Calibration of a Machine Vision Complex Based on the Use of Color Bands

详细

The problem of scanning the form of raw material in the course of pattern cutting in the fabrication of planar parts is considered. A machine vision system is used to solve the problem. In the context of the problem questions of calibration of the system and the elimination of optical distortions become critical with the use of such technologies. Different methods of calibration of the cameras of computer vision systems are presented. It is proposed that the use of test objects be rejected in favor of marked bands applied along the extreme edges of the working region of the pattern complex as well as the use of an algorithm for searching for marked bands on the images produced by the system.
