摘要
双相机工业摄影测量系统具有高精度、非接触式实时动态跟踪测量等优点,广泛应用于航空航天领域。目前,其精度校准主要针对点坐标和长度测量。本文基于六自由度测量原理,建立误差模型,提出将高精度电子经纬仪和三维移动平台作为标准设备的位姿测量校准方法,并通过对比测量值与标准值的差异,实现姿态(航向、俯仰、翻滚)和距离(水平、纵深、垂直)的精度校准。试验表明:该方法能有效评估测量精度,为高精度测量提供保障。
The dual camera industrial photogrammetry system has the advantages of high precision,non-contact real-time dynamic tracking measurement,and is widely used in the aerospace field.At present,its accuracy calibration mainly focuses on point coordinates and length measurement.This article is based on the principle of six degrees of freedom measurement,establishes an error model,and proposes a pose measurement calibration method using high-precision electronic theodolites and 3D mobile platforms as standard equipment.By comparing the differences between the measured values and the standard values,the accuracy calibration of attitude(heading,pitch,roll)and distance(horizontal,depth,vertical)is achieved.The experiment shows that this method can effectively evaluate measurement accuracy and provide guarantees for high-precision measurement.
