Studying Combined OpenCV image processing algorithm libraries with machine vision technology, build a robot vision system. OpenCV vision algorithm is the core of the system, dual cameras as the system input, using VC++ 6.0 program interface and tools to write Windows applications, build a robot vision system architecture. By way of the development environment is configured correctly, make use of the function of OpenCV algorithms, vision measurement technology, video processing and image processing technology, and to improve and optimize the vision algorithms to achieve camera calibration, realize Camera single and binocular target calibration, and improve the calibration accuracy and speed. To through Optimize the OpenCV vision algorithms applied to robot vision measurement, the OpenCV algorithms plays a better role in enhancing the visual measurement speed and accuracy. Shorten the development cycle of the visual system and Shorten the development cycle of the visual system.
