Description

Technical Field

[0001] The utility model relates to the technical field of airborne LiDAR equipment transportation, in particular to a shock-absorbing and protective device for airborne LiDAR equipment transportation. Background Art

[0002] Airborne LiDAR is the abbreviation of laser detection and ranging system. It integrates spectral imaging equipment such as GPS, IMU, laser scanner and digital camera. The active sensing system uses the returned pulses to obtain high-resolution distance, slope, roughness and reflectivity information of the detected target, while the passive optoelectronic imaging technology can obtain digital imaging information of the detected target. After ground information processing, the three-dimensional coordinates of each ground sampling point are generated. Finally, after comprehensive processing, the three-dimensional positioning and imaging results of the ground area along a certain strip are obtained. At present, when transporting airborne LiDAR equipment, the transport box does not have a shock-absorbing function, resulting in the airborne LiDAR equipment being easily damaged by shaking during transportation, affecting the normal use of the airborne LiDAR equipment and causing unnecessary losses.
