Abstract
Aiming at the problem that camera calibration method based on active vision was too high in requirement in the form of camera motion, and difficult to realize, a simplified method of camera calibration was proposed which needed only 2 times pure translation motion.In this method, the basic matrix F was obtained by 2 pairs of matching points, and the linear solution of the internal parameters of the camera was obtained by the intrinsic relationship of the basic matrix, then the 4 internal parameters were obtained.The simulation experiment results showed that this method could be controlled within a certain range of simulation error under certain conditions, which could meet the requirement of the accuracy of the robot location, and reduce the computation time and improve the real-time performance of the robot.
