| 摘 要： | 基于机载LiDAR技术的测绘系统必需对其进行标定和校正,优化导航定位、定姿系统的测绘精度。冗余的观测数据不仅可以评估系统监测粗差的能力,还可以分析未检测粗差对导航结果的影响,评价结果的可靠程度。本文基于内、外可靠度理论,进行抗差检校模型的质量控制,实例分析表明该理论能有效衡量抗差模型对粗差的识别效果。

| Abstract: | Airborne LiDAR technology-based mapping system must be calibrated and corrected to optimize the mapping accuracy of position and attitude determination system.Redundant observation datas can not only evaluate the capacity of detecting gross error,but can also analysis impact on the results of navigation without detecting gross errors and evaluate the reliability of results.In this paper,quality control of robust calibration models is researched based on internal and external reliability theory.The case anal... |
