Abstract In this paper, the model VUX-1 laser was used as an example to calculate the influence of multitimearound(MTA) on the height of the aircraft. Then according to the requirements of the point cloud density, scanning frequency, scanning speed and other indicators, and in accordance with the principle of air aerial photogrammetry and LiDAR data acquisition specification, the difference between traditional photogrammetry and airborne LiDAR was distinguished, and a cue from traditional photogrammetry was used for reference. The changes of laser range under different conditions, such as the different types of targets in the test area,the different types of targets and the variation of the most remote ranging capability, were determined. By taking into account the above problems,a route for the airborne LiDAR system was designed. At last, the across track point spacing and the along track point spacing were calculated respectively for analyzing the reasons and determining the feasibility of the route design scheme.
