摘　　要：提出了无地面控制点机载LIDAR航空测图的新方法,即利用小区域的检校区快速求取安置角误差,从而将之应用于整个测区,能够快速准确地获取地面点坐标。本文探讨了该方法的可行性,并得出相比传统求取安置角误差的方法,新方法的数据处理效率更高、优势更突出。The paper puts forward a new method of aerophotogrammetry for airborne LIDAR without ground control, which is to use small calibration area to acquire placement angle and apply it to the whole surveying area, and the coordinates of ground points could be obtained rapidly and precisely. The paper studies feasibility, and compares the method of obtained placement angle using condition of the surveying area. Data processing is more efficient by the new method with more prominent advantages.
