Image Mosaic for On-machine Measurement of Large-Scale Workpiece
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.
