一种基于MATLAB的改进的水准网平差程序设计与实现

Design and Implementation of a Leveling Net Adjustment Program Based on MATLAB

为了高效准确地计算水准网数据,通过分析水准网的数据结构,对常规的MATLAB水准网平差程序做了进一步的改进,重点研究了已知水准点点名为字母的情况下,误差方程系数矩阵与常数项的建立方法。基于间接平差原理使用GUI功能实现了水准网平差。解决了一般的MATLAB平差程序中需要手动替换点名才能平差的问题。实验引入实例数据证明了程序的正确性与实用性,对MATLAB测绘数据处理有一定的参考与指导意义。

In order to calculate the leveling net data efficiently and accurately, by analyzing the data structure of leveling net, a further improvement is made to the adjustment program of MATLAB leveling net. Based on the principle of indirect adjustment, GUI function is used to implement leveling network adjustment. It solves the problem that in the general MATLAB adjustment program, it needs to manually replace the name to adjust. The application of real data in the experiment proves the correctness and practicability of the program, which has certain reference and guiding significance for MATLAB mapping data processing.
