Abstract

At present, the large-scale workpiece need to be measured on the coordinate measuring machine(CMM) in the manufacturing process resulting in low efficiency and hard quality controlling. In this paper, an image mosaic method for on-machine vision measurement of large-scale workpiece was presented. The camera was mounted on the numerical controlled milling machine to acquire multi-images by controlling the moving of working table. Rule of image taking, definition of overlapped image pairs, feature point detection and projective matrix computation were discussed. Image mosaic of large-scale workpiece with high precision was realized. Size measurement result proved the effectiveness and high efficiency of this method.

基于图像拼接的大型工件在线测量
目前,大型工件在制造过程中需要在三坐标测量机上进行测量,导致效率低,质量控制困难。提出了一种用于大型工件的机器视觉测量的图像拼接方法。该摄像机安装在数控铣床上,通过控制工作台的移动来获取多图像。讨论了图像采集规则、重叠图像对的定义、特征点检测和投影矩阵的计算。实现了大型工件的高精度图像拼接。尺寸测量结果证明了该方法的有效性和高效性。
