详细分析了机载激光水深测量的各种误差,着重讨论了IMU姿态测量误差对机载激光定位的影响。根据实际可能的误差数据,并联合扫描角误差、测距误差和平台坐标系原点误差进行计算分析,得出了不同的量测误差对目标3维定位误差的综合影响。
In this paper the various errors of airborne laser bathymetry were analyzed in detail, the survey error of IMU effect on the airborne laser bathymetry was discussed in stress. The errors of airborne laser bathymetry were computed and analyzed associate with scan error, telemeter error and origin of coordinate system error, according to the possible error datum in fact, it concluded that the synthetically effects of 3D targets position for different survey errors.
