浅谈机载激光雷达数据处理

Discussion on Airborne LiDAR Data Processing

机载激光雷达是激光探测及测距系统,它集成了GPS、IMU、激光扫描仪。其中主动传感系统(激光扫描仪)利用返回的脉冲可获取探测目标高分辨率的距离、坡度、粗糙度和反射率等信息,而被动光电成像技术可获取探测目标的数字成像信息,经过地面的信息处理而生成逐个地面采样点的三维坐标,最后经过综合处理而得到沿一定条带的地面区域三维定位与成像结果。

Airborne LiDAR is a laser detection and ranging system,which integrates the functions of GPS,IMU,laser scanner. The active sensing system（ laser scanner） uses the returned pulse to obtain information such as the distance,slope,roughness and reflectivity of the target,and the passive optical imaging technology can obtain the digital imaging information of the target,and generate a three-dimensional grid of all sampling points with coordinates,then through integrated processing,the three-dimensional positioning and imaging results along a certain strip on the ground are obtained.
