Abstract:Combining machine vision and laser measurement technology together,the fast online detection for the production line of precision bearing was accomplished.The quality inspection of the bearing online production was realized by using the combination of array camera and the industrial laser sensor,and the quality defects detection and the size accuracy measurement were finished.A complete set of automatic detection system was established which could be used to achieve fast positioning,surface defect detection and multi position measurement.At the same time,it has the advantages of visual detection and laser detection by which online detection with high speed,high efficiency and high precision was realized.
