| 摘 要： | 针对线阵CCD相机标定时镜头会产生畸变的情况,提出来一种利用交比不变的方法,考虑镜头同时存在的径向畸变和离心畸变,对畸变参数进行标定,建立畸变校正函数,并利用Matlab做出镜头畸变曲线,分析了线阵CCD相机镜头仅仅存在径向畸变时对结果的影响和径向畸变与离心畸变都存在时的影响。这种方法应用于相机标定之前,可以有效地消除线阵CCD相机镜头误差对整体标定结果的影响。

| Abstract: | Connection with linear CCD camera calibration lens will be distorted, put forward a same cross -ratio method, considering the presence of the lens has the radial distortion and centrifugal distortion in same time, distortion calibration parameters for the establishment distortion correction function and to make use of matlab to produce lens distortion curve, to analyzes linear CCD camera lens when the mere presence of radial distortion influence on the results and the radial distortion and centrifugal distortion effects collaborative influence on the results. This method is applied to the camera calibration be- fore, the error linear CCD camera lens on the overall calibration results is eliminated. |
