摘要
本文推导了以球心三维坐标及半径为参数的平差模型,据此设计和完成了一个球面拟合程序,能够实现球半径已知或未知这两种情况的拟合计算。程序还可批量处理多个独立球体的观测数据,进行拟合结果与设计数据的自动匹配及对比。利用该程序对模拟数据进行分析,得出一些对采集方案有指导作用的结论。
This paper inferred the adjustment model which uses the three-dimensional coordinates of the center and the radius of the sphere as the parameters. Then a spherical fitting program was designed and implemented. This program could execute the fitting calculation with known or unknown radius. What＇ s more, it batched processing observation of multiple independent spheres, and the result of fitting was automatically matched and compared with the design data. There were some guidance conclusions on the testing pro- gram after analyzing the simulated data by the program.
