【摘要】：针对目前标靶定位精度的估计大多是基于单个位标靶进行的,没有顾及各站标靶之间的关系,该文提出基于激光束法区域网中的同名距离,对标靶定位坐标进行检核和验算。整体思想是通过查找扫描站间标靶有两个或两个以上为同名标靶时,以相邻站同名距离相等为条件列立同名距离方程式,平差计算标靶定位精度,验算标靶定位精度是否满足某种工程测量的要求。通过实际工程案例,说明了激光束法区域网平差前的概算对标靶定位坐标检核和精度估计的必要性。
[Abstract]:In view of the fact that the estimation of target positioning accuracy is mostly based on a single target, without considering the relationship between the targets of each station, this paper proposes to check and check the location coordinates of the target based on the distance of the same name in the regional network of laser beam method. The whole idea is that when there are two or more targets with the same name in the target between the scanning stations, the equation of the same name distance is set up under the condition of equal distance between the adjacent stations, and the positioning accuracy of the target is calculated by the adjustment. Check whether the accuracy of target positioning meets the requirements of some engineering measurement. The necessity of checking the coordinates and estimating the accuracy of the target positioning by the estimation of the laser beam method before the adjustment of the regional network is illustrated by an actual engineering case.
