Photogrammetry developed from the direct linear transformation (DLT) method and the expansion of the direct linear transformation method, and a radial alignment constraint based on (RAC) of the two-step method (Tsai method), there are different positions on the template Zhang Zhengyou plane method (Zhang), also based on the camera itself, without external calibration object moving self-calibration method. OpenCV, Intel Open Source Computer Vision Library, which consists of a series of c functions and a small amount of C++ classes form a powerful image processing, image analysis and image understanding functions, and its functions for a lot of the classic aspects of image processing and computer vision algorithms It is a good tool for machine vision research and development.
