利用安置角检校进行机载LiDAR点云数据与同步影像快速配准

Boresight Calibration Based Fast Registration Between Airborne LiDAR Points Clouds and Synchronous Images

在对安置角进行综合分析后,以精确的机载LiDAR数据为基础,联合高分辨率影像对空间点进行高精度定位,建立了机载LiDAR和摄影测量联合平差模型,完成了无需控制场的相机安置角检校,较好地实现了机载LiDAR数据与同步影像的精确配准。

There is a different imaging mechanism between LiDAR data and aerial imagery,so it is difficult to adopt traditional automated registration method.On the basis of comprehensive analysis of boresight misalignment,high-precision LiDAR data integrated with high-resolution aerial imagery are used to precisely position 3-dimentional object space points.Then a combined adjustment model for LiDAR data and aerial images can be built to achieve boresight registration without any control fields,which can guarantee high-precision registration of LiDAR data and aerial image.
