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 |
