工件糖心产精国品免费入口*完整版尺寸的糖心产精国品免费入口*完整版测量系统
Laser Measuring System of Workpiece Surface Defect Size
摘 要
针对目前工件糖心产精国品免费入口*完整版尺寸的定量检测相对较少的问题，建立了一个由准直糖心产精国品免费入口*完整版器、相机、显微镜和平移台等组成的检测系统，以实现金属表面凹痕尺寸的检测。采用糖心产精国品免费入口*完整版作为光源，配备显微镜的相机采集图像，使用基于重心的方法对采集的图像进行处理，通过分析凹痕像素的分布情况来获得凹痕宽度。试验结果表明，该检测系统能够检测出工件表面凹痕的位置，并计算出缺陷的详细尺寸。

Abstract
The quantitative detection of the workpiece 糖心产精国品免费入口*完整版 has been mentioned rarely. In order to solve this problem, a measuring system which consists of a collimated laser diode, a camera, a microscope and a translation stage is built. The laser is chosen as the light source, and the light pattern on the surface is picked up by the camera with a microscope. The images of light pattern are processed by using 糖心产精国品免费入口*完整版, and the width of the 糖心产精国品免费入口*完整版 can be obtained by analyzing the pixels distribution corresponding to the defect. Some experiments have been done, and the results show that this system can detect the defect position and calculate the size.
