Vision Measurement is a technique using machine vision for accurate measuring and locating space geometrical dimensions. The technique is able to effectively improve the accuracy and efficiency of industrial measurement. Applying the HALCON and VC＋＋ mixed programming method, the electronic components vision measurement software tool is developed. And a set of core algorithms and their function are realized, such as measurement image capture and display, vision measurement. We also design and construct the hardware platform, which is comprised of industrial digital camera, industrial lens, illuminant and other instrument. Based on the platform, a series of experiments are done to verify the reliability and stability of the tool. The results indicate that the system test is fast and the test accuracy reaches the expecting qualification.
