摘　　要：介绍了机载激光扫描的现状。在机载激光扫描系统定位原理的基础上,讨论了俯仰角、侧滚角、偏航角误差对激光脚点定位精度的影响并进行了详细分析;利用目前IMU实际测量精度进行模拟计算,得出了一些有益结论,对于理解机载激光雷达定位精度和实际应用具有一定的指导意义。The status quo of airborne laser scanning was briefly introduced. On the basis of airborne laser scanning system positioning principle, the impact of the pitch angle, roll angle and yaw angle on laser point positioning accuracy was analyzed in detail. After simulated calculations using IMU practical measurement accuracy presently, some useful conclusions were obtained, which have certain guiding significance for the understanding of airborne laser positioning accuracy and practical application.
