| 摘 要： | 针对靶场光电测量中使用的双站交会方法需要切换交会公式、交会精度不高的问题,提出了一种在直角发射坐标系中,基于高斯-牛顿法的多站交会方法。通过仿真试验将其与传统双站交会方法进行比较,证明了这种多站交会方法具有良好的收敛性和较高的交会精度。

| Abstract: | In the typical shooting range measuring system,there are 3 or 4 theodolites placed on different spots to do tracking and measuring. But when we do intersection,only 2 of them are used by Two Station Intersection(TSI),which causes data wasting and low data processing accuracy. This article proposes a new method named Multiple Station Intersection (MSI) to solve that problem. MSI supposes that all the theodolites have equal importance in intersection,and MSI gets the Hesse Matrix of the intersection equation,then MSI do Gauss-Newton iteration and get the accurate intersection result. In simulation experiment,we do both TSI and MSI with the same group of data. Experiment results show that MSI have excellent convergence and accuracy. |
