摘要
微小型位置姿态测量系统(MPOS)是为观测载荷提供实时运动补偿信息的关键设备。针对国产MPOS在实时单点、事后差分和实时差分(RTK)定位等不同工作模式下的精度测试问题,结合通用航空载荷研制要求和摄影测量工程应用经验,提出了一种基于基准POS直接对比的测试方法和基于POS辅助空中三角测量方法,对国产MPOS测量精度及成图精度开展综合分析评估。结果表明,提出的直接对比法及航测成图法能够真实、客观反映国产MPOS系统在实际工程应用中的性能状态,且在相对理想作业条件下,采用一定数量控制点参与区域网联合平差,能够满足1∶1000成图限差要求,测量精度及工程应用效能与APX-15 UAV等国外同类型产品水平相当。
Micro position and orientation system(MPOS)is a key device that provides real-time motion compensation information for observation payloads,and its reliability and stability have a direct impact on the accuracy of data results.Aiming at the measurement accuracy testing issues of MPOS system under different working modes such as real-time single point,post differential and real-time differential(RTK)positioning,combined with the development requirements of general aviation load equipment and practical experience of photogrammetric engineering application,a method based on direct comparison of reference POS system and a method based on POS assisted aerial triangulation are proposed,comprehensive verification and evaluation of the measurement accuracy and aerial mapping accuracy of the domestic MPOS system engineering prototype.The experiment results demonstrate that the proposed direct comparison method and aerial mapping method can truly and objectively reflect the performance and status of domestic MPOS in practical engineering applications,and under relatively ideal operating conditions,a certain number of control points are used to participate in the combined adjustment of the regional network,which can meet the accuracy requirements of 1∶1000 scale mapping limit,the measurement accuracy and engineering application efficiency are comparable to the level of similar foreign products such as APX15 UVA.
