A quick vision inspection system MBMS for the large number of small size guide holes on complex aircraft parts was designed and implemented.The key techniques concerned were studied and discussed in details.The system combined a visual sensor with a multi-axis CNC equipment.A method to calibrate the system’s internal and external parameters was proposed.The programming method to generate NC inspection program was discussed in detail,and the guide holes’inspection or-der was optimally planned.An accurate and stable method was proposed to locate the guide hole in the image.Finally,the evaluation of the guide hole’s machining precision was achieved by comparing the real image with the underlying virtual image.The proposed method provides an approach to quick and accurate inspection of the large number of small size guide holes on complex aircraft parts.
