摘要:
详细分析了IMU/DGPS机载激光定位测量的各种误差，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三维定位误差的综合影响。

Analysis and estimation on the IMU/DGPS airborne laser scanning errors
Abstract:
In this paper the various errors of IMU/DGPS airborne laser scanning were analyzed in detail, the survey error of IMU effect on the airborne laser scanning by was discussed in stress. The errors of IMU/DGPS airborne laser scanning were computed and analyzed by associating with scan error, telemeter error and origin error of coordinate system. According to the possible error datum, it was concluded that the different survey errors have synthetic effects on 3D targets position errors.
Key words:  airborne laser  attitude degree  position errors
