摘要
基于机载LiDAR系统组成及工作原理,对激光点云数据精度评定方法进行研究,主要包括内插特征点对比分析法、统计分析法、斜面几何分析法、误差传播定律分析法。各种方法都有各自的优缺点,在进行具体精度评定时,几种方法要结合使用。
Based on the system composition and operational principle of the airborne LIDAR,the paper researches the accuracy evaluation method of the lasers point cloud data,including the method of interpolation characteristic comparative analysis,the method of statistical analysis,the method of plane geometry analysis,the method for analysis of error propagation law and etc.Each method has its own advantages and disadvantages when evaluating the accuracy of lasers point cloud data,and these methods should be combined.
