摘要:A rapid quality detection system for multiple micro-holes fabricated by electrochemical machining (ECM) is proposed by studying on the optical features of multiple micro-holes. First, the edge of multiple micro-holes is detected exactly with the digital image processing techniques. Second, the multiple micro-holes are recognized through image skeleton extraction and region segmentation algorithm. Then, the least square circle fit arithmetic; the new roundness measurement algorithm and the surface roughness measurement method are synthetically used in the processing of geometric feature recognition of each micro hole. Finally, the practical results prove that the rapid quality detection system is provided with a fast detection speed and high precision for meeting the quality inspection requirement of multiple micro-holes.
