| Abstract: | An accurate calibration to the CCD measurement camera is needed in order to ensure the high testing precision of automatic on line vehicle driving wandering test system.There are two common methods for CCD camera calibration,namely spatial resection and direct linear transformation(DLT).By analyzing the basic theories of the two calibration methods and the features of the testing system,the selection rule of the calibration method as well as the influence of control point type on calibration accuracy are st... |
