基于数字图像的曲线磨床尺寸检测系统

Dimension Measurement System of Profile Grinding Machine Based on Digital Image

传统的光学曲线磨床的加工尺寸主要是依靠光学投影法检测,这里提出了基于数字图像的方法,采用图像边缘检测、亚像素定位技术、边缘轮廓提取等图像处理技术,在美国NI公司的Labview平台下开发图像尺寸检测系统。

Optical projection is the traditional dimension inspecting method in profile grinding machine. A new method was presented to replace optical projection system with digital image measurement system. Image processing technologies such as edge detection, sub-pixel mapping and edge contour extraction were applied based on the platform of labview.
