With the use of edge detection technology, we can search the image edge of form grinding wheel. The "mapping function" is used to transfer image pixel coordinate to real metric coordinate. The captured image possesses error lower than 5 □m. 　　We use Rough Blending Method(Correlation Method) and Fine Blending Method (Optimization Method) to combine several images to one frame. Experimentresults show that the wear of form grinding wheel and the radius of form grinding wheel can be detected with accuracy about 10□m.
