一种星载激光测高仪光斑内定位方法
|
摘要
提出一种利用铅垂线轨迹法及高程结构信息约束的星载激光测高仪光斑内定位方法。在星载激光测高仪辅助立体摄影测量体制下,以激光回波中包含的高精度高程结构信息作为约束条件,在足印光斑内,配合立体图像匹配生成的数字高程模型,选取定位候选点,并通过铅垂线轨迹法优化定位候选点高程值,消除立体图像定位误差引起的高程误差,获取符合高程结构约束的一系列位置的三维坐标。试验结果表明,该方法能够实现大光斑星载激光测高仪足印内的定位,高程定位精度为0.16 m,平面定位精度与立体图像一致。
A positioning method in footprint of space-borne laser altimeter based on vertical line locus(VLL)algorithm and elevation structure constraint is proposed.In the space-borne laser altimeter supported satellite photogrammetry frame,positioning point candidates are acquired in the footprint with digital surface model(DSM)generated by stereo images,according to the relative elevation structure information of the waveform.Then,elevations of positioning point candidates are also improved using VLL algorithm compared with the elevation structure information,which can eliminate the position errors of stereo images.Experiments show that the method proposed is effective in big footprint space-borne laser altimeter positioning,and the elevation positioning accuracy is 0.16 m,plane positioning accuracy is the same with stereo images.
