摘 要: 根据线阵CCD对二维图像进行扫描检测的特点,提出一种基于链码自分段配准技术的轴类零件尺寸检测方法。该方法能自动对轴类零件轮廓曲线进行分段,然后进行测量,最终测出轴类零件每一段的尺寸。采用该技术,能检测出复杂轴类零件的尺寸,具有鲁棒性好、直径测量的检测误差较小的特点。 A method for shaft part size detection based on self-division chain code match is proposed according to the characteristics of scanning 2-D image with linear CCD. It can divide the boundary of the parts into pieces automatic, then get the size of each piece. The algorithm is quite robust in the complex shaft part testing. The testing experiments show that the detection of diameter measurement error is smaller.
