As the present day digital microsystems do not provide specialized microscopes that can detect cutting-tool, analysis software has been developed using VC . A module for verge test and image segmentation is designed specifically for cutting-tools. Known calibration relations and given postulates are used in scale measurements. Practical operations show that the software can perform accurate detection. 相似文献
