摘　　要：不规则物体投影面测量系统,以环形灯为光源、CCD为图像采集单元。通过图像处理的方式指示微位移机构实现自动调焦,将被测物体清晰成像在CCD像面上。然后与标准件所呈的像对比,得到不规则物体的投影面积。该系统能方便的实现不规则物体投影面积的检测,测量精度高。The measure system for erose object projection area uses circle lamp as lamp house and CCD as image collection unit. The automatic focusing is realized by micro displacement equipment through image processing. The object is projected on CCD, and then compared with the standard projection the erose object projection area is acquired. The system can effectively and precisely measures the erose object projection area.
