基于AGV的复合测量系统自动转站激光指向偏差修正研究OA

Frequency-modulated LiDAR,in conjunction with automated guided vehicle(AGV),constitutes a composite measurement system that integrates automatic station-transfer functionality with long-range non-con-tact measurement capability.This system has been widely applied in the dimensional inspection of large-scale components.Nevertheless,angular positioning deviations inherent to the AGV body may cause the laser beam to miss the scanning spheres designated for station-transfer,thereby leading to failure of the automatic station-transfer procedure.The capability of the direct-scanning laser tracker ATS800 to support reflector-based meas-urements is utilized.Specifically,a single reflector is introduced during the station-transfer process to correct the laser pointing deviation,ensuring that the laser beam can accurately target the scanning spheres,thereby accomplishing the automatic station-transfer.On the basis of this approach,theoretical derivations and algorith-mic formulations are developed,and validation experiments are designed and conducted.The experimental re-sults confirm that the proposed scheme and its underlying algorithms are theoretically rigorous and practically effective,thereby providing a solid foundation for the application of similar methodologies in future scenarios.
