Aiming at the problems existing in the detection of high precision optical devices, and combining with the market demand, this paper develops a high precision optical element surface detection system, based on Blob analysis of machine vision to detect the surface quality of high-precision optical components fully automatically and constantly. The system consists of four parts: automatic photography, image processing, image mosaic and surface data statistics. While improving the detection efficiency and reducing the cost of detection, the accuracy and reliability of high precision optical elements detection are improved. The measurement accuracy reaches the μm degree. It has a good detection performance.
