The abrasive grain shape and its distribution in the grinding wheel have an influence on the grinding characteristic of the wheel. Therefore, we aim to develop the on-machine 3D measurement system by binocular stereopsis for abrasive grain shape and its distribution in the grinding wheel. In this paper, the 3D shape measurement is carried out using the omnifocal images. Comparing between the ratios of outlier by use of optical filters, we aim to improve the stereo pair images by decrease the outlier of matching. Thereafter, we analyzed the grinding wheel surface 3D topography and the abrasive behavior by performing tracking observation of the grinding wheel working surface in the grinding process by using this system.
