The tool is machining tooling , tool parameter detection has become particularly important with the growing popularity of machine tools, machining centers and, increasingly, high workpiece accuracy requirements . Traditional tool parameter measuring means low measurement accuracy and efficiency , human factors large , can not meet the requirements of modern production . The machine vision technology is fast, informative , high precision, and characteristics of non-contact machine vision technology applied to the tool parameter detection tool parameter detection system . This paper analyzes the the tool parameter detection status quo , characteristics and advantages of the machine vision technology , this research content and focus , and the detection system overall program design . Secondly, the design of the imaging system , combined with the system overall program and the general principle of the selection , select the light source , camera , the lighting the way ; through the the calculated lens of indicator parameters , optical design software ZEMAX optimized structure determined after repeated testing and modifying the \The lens design of this article is based indicator parameters as the basis of the imaging system hardware and of the tool , reduces the image acquisition error . Then described in detail the image acquisition and image processing technology , theoretical and experimental research in image processing , correlation algorithm selected histogram specification and median filtering as enhance contrast , the method of filtering image noise , after tool image after the division of the single threshold , using closed morphological processing can be effectively removed irrelevant to the structure , the commonly used method of edge detection comparator , Canny edge detection operator is able to detect the edge of the clear of the tool , a higher positioning accuracy . Articles LabVIEW software platform application IMAQ Vision module to complete the compilation and debugging of software , modular thinking in writing software , programming of the different functions of the corresponding sub- VI , in order to verify the performance of the detection system and effect , milling and turning tools blade test and verify .
