摘要
针对测绘相机坐标系与其立方镜之间关系的标定方法,建立了两坐标系间的转换矩阵,分析了在测量中引起的误差源,并基于建立的数学模型,利用蒙特卡罗法对这些误差进行了精度分析。使用Matlab进行了相关模拟与解算,给出了误差分析结果及误差曲线,得到了各误差在整个误差链中的权重,为后期实验打下了基础。误差分析结果表明,该方法的标定精定可以满足总体标定要求,具有实用价值。
In response to the method of calibrating mapping camera and cubic prism coordinate system ,the transformation matrix for coordinate system was established. The source of error in the measurement was analysed, and the precision of the coordinate system transfor- mations was investigated. Then based on the above mathematical model, error was analysed employing Monte Carlo method. Simulations and related solutions were carried out by using Matlab. Finally, the results of error analysis and the error curves were given which lay the foundation for the later experiments. The error analysis indicates that the precision can meet the requirements of the actual projects.
