| Abstract: | The nonlinear integrated optimization of the CCD camera calibration based on radial alignment constraint was introduced. The Harris algorithm was used to detect the calibration plate corner of the image coordinates so as to ensure the stability and reliability of corners of the board;after the RAC two-step calibration , all the camera model parameters based on radial alignment constraint was nonlinearly integrated optimized by the Levenberg-Marquardt algorithm,and the accuracy of the calibration is increase... |
