【Abstract】 The paper presented a machine vision system for inspecting the diameter of the tail-hole in a hard disk driving shelf which was needed in mass customization production and inspection.Its overall design was explained;the improved randomized Hough transform and the fitting algorithm based on circle-points were proposed to calculate the diameter of the tail-hole circle;the data for experiments on repeatability and correlation were given.The inspection results indicate that the machine vision system has the strengths of non-contact,online,real time,fast speed and appropriate precision,and that the objective of manufacturing zero-defect products is achieved.更多还原
