基于GPS、姿态和激光测距的三维遥感直接对地定位

传统的遥感对地定位是依据野外测设（或地图上量取）地面控制点采用立体像对或空间变换等原理进行的，而三维遥感直接对地定位采用了ＧＰＳ定位技术，姿态测量系统和扫描激光测距技术来直接对同步获取的遥感数据进行三维定位，能够实时（准实时）地得到地面点的三维位置和遥感信息，它具有快速实时（准实时）且无需地面控制，是遥感对地定位的重大突破。

3D Remote Sensing Directly Positioning for Ground Based on GPS,Attitude and Laser Range Finder

Traditional remote sensing uses stereopair or space transformation theory to position for ground based on ground control points which are surveyed in field or in map, but 3D remote sensing system applies GPS receiver, attitude measure unit and scanning laser rang finder to directly position for the remote sensing pixel which is captured simultaneously. Thus, it can obtain 3D position and remote sensing information of each ground point at the same time (almost in real-time), from airborne test we can find 3D remote sensing directly positioning for ground is a breakthrough in remote sensing because it is fast. real-time and without ground control points.
