Target Point Position Estimation for Double-theodolite Non-uniplanar Intersection
摘要
Abstract
Aimed at the problem that the target point not just in the common vertical line for double-theodolite non-uniplanar intersection,a method of estimating the target point position nearby spatial region of the common perpendicular is presented. The spatial region is the cuboid spatial region that taking the common perpendicular as diagonal,and each side separately parallels with double-theodolite measurement coordinate system triaxiality. When estimated the target point position,in consideration of the difference of angular accuracy that theodolite azimuth angle and pitching angular, and in view of the distance between target point and theodolite influence on space point coordinates precision,the simulation result of adopting the Monte Carlo method shows that the spatial point position precision of the new method is not inferior to the traditional methods that estimate the object points position on the common perpendicular,even improved by above 5 % in a specific state. The results show that the new method is feasible and available.关键词
