狭长受限空间锚节点定位的测距仪双侧自由设站法
Bilateral-Free Setting Station Method Using Hand-Held Laser Rangerfor Anchor Node Positioning in Long-Narrow Confined Spaces
摘要
Abstract
Aiming at the problem that the existed anchor node positioning methods cannot be successfully applied in the long-narrow confined spaces,this paper proposed trilateration network layout methods including both center-free station method and bilateral-free station method based on both geodetic quadrilateral method and free station method.Redundant observations and coordinates variance-covariance matrix of four trilateration network layout methods mentioned above are computed and analyzed,and results show the bilateral-free station method is the best one.Further,the structure strength function of the bilateral-free station method is investigated in detail.At the end,to test the accuracy and reliability of the bilateral-free station method,anchor node positioning experiment using Leica-S910 hand-held laser ranger is implemented in the indoor-outdoor location test field of China University of Mining Technology.The positioning results show the bilateral-free station method can get the optimized trilateration network with the position RMSE 15.1cm which can satisfy the accuracy requirement in long-narrow confined spaces.关键词
