| Abstract: | From the position equation of airborne LiDAR system,the error source,such as the IMU measures error,the GPS position error,the laser distance measurement error,the laser scan angle error and so on,were discussed detailedly based on the error propagation law in the paper.The influence rule of those errors were studied,and the academic position precision were discussed,The simulation computation indicated that the results could be a good reference to practical application. |
