基于最小二乘支持向量回归的小零件精密测量技术（Precision Measurement Technology for Small Parts Using LSSVR）
齿形链板 精密测量 图像处理
2009/9/11
以圆销式齿形链板为研究对象，提出了结合图像处理技术和最小二乘支持向量回归的小零件精密测量方法。以CCD作为传感器采集图像，通过去噪和二值化等图像预处理技术获得待测零件单像素边缘轮廓信息。根据零件特点确定待测区域，并取出该区域中图像点的坐标作为最小二乘支持向量回归的训练点集，进行直线和圆的亚像素回归。对回归结果进行处理得到待测直线间夹角、圆孔直径、圆度误差和圆心距等几何参数。实验结果表明提出的方法不...
