| 摘 要： | 介绍了一种测绘相机坐标系与立方镜之间关系的标定方法。对两坐标系的转换矩阵、标定方法和标定精度进行研究。推导了两坐标系的关系,建立了坐标系间的转换矩阵。利用高精度二维转台、0.5″经纬仪和平行光管完成了测绘相机与相机立方镜坐标系之间的角度测量。最后,对标定精度进行了分析。误差分析结果表明:该方法的标定精度优于2″(1σ),可以满足测绘相机坐标系与立方镜转换关系的标定要求,具有实用价值。

| Abstract: | A method for calibrating mapping camera and cubic prism coordinate system was introduced. The transformation matrix, calibration method and precision of the coordinate system were investigated. The relation of coordinate system was calculated, and the transformation matrix for coordinate system was established.Then, the angles between the mapping camera and the cubic prism coordinate system were tested by combining of high-accuracy 2D turntable, 0.5″ theodolite and autocollimation telescope. Finally, the calibration precision was analyzed. The error analysis indicates that the precision is smaller than 2″(1σ),which shows that the method can meet the requirements of calibrating mapping camera and cubic prism coordinate system and is valuable for practical application. |
