摘要：针对加工过程中刀具磨损会影响零件加工精度的问题，利用图像处理技术实现了刀具角度的测量，以达到对刀具磨损情况进行动态跟踪的目的。以Matlab软件作为图像处理平台，通过图像灰度转换、二值化、边缘提取等技术手段，获得了刀具边缘轮廓，进一步用最小二乘法将轮廓拟合，最终求出了刀具角度。实验结果表明，该方法能较好地测量刀具角度，也可用于刀具几何参数的测试。

Abstract: Aiming at the cutting tools wear having impact on workpiece quality in the process of machining, image processing technology was adopted to measure the tool angel and realize the dynamic tracking of tools wear condition. Based on Matlab image processing toolbox, the technology of gray level conversion, binary conversion and edge extraction was used to extract tools features, then the method of least square was applied for edge fitting, and finally the angle of cutting tool was measured. Experimental results show that this method is able to get the tool angle effectively, and it can also be used to measure the tool geometric parameters.
Key words: image processing; edge extraction; tool angle
