Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping instruments, and more specifically to a three-dimensional terrain scanner for surveying and mapping. Background Art

[0002] Terrain scanning is generally performed using a total station, and the three-dimensional terrain scanner needs to be used in conjunction with an aircraft during operation. However, when commonly used terrain scanner devices are used in conjunction with an aircraft, a storage space needs to be set up at the bottom of the aircraft to provide anti-collision protection for the terrain scanner device. This not only limits the type of coordination between the terrain scanner device and the aircraft, but also requires touching before storage, which reduces safety of use. In addition, after the terrain scanner device is assembled with the aircraft, the scanning direction and angle of the scanning lens cannot be adjusted individually, and coordination with the aircraft is required, which brings inconvenience to terrain surveying and mapping.

[0003] For example, a terrain scanner disclosed in announcement number CN220230521U includes: a scanning device; the scanning device is connected to an aircraft via a connecting component, the scanning device is located below the aircraft, and scans the terrain below; the angle between the scanning device and the bottom end surface of the aircraft is adjusted by the connecting component so that the scanning device is perpendicular to the ground.

[0004] It can be seen from the above-mentioned public scheme that the scanning direction and angle are adjusted by the connecting assembly when the scanning device is connected to the aircraft, but cannot be adjusted when the assembly is completed and used, and the aircraft needs to be provided with a volume cavity, which shrinks upward for protection when the bottom of the scanning device is touched, thereby reducing the application scope of the scanning device and providing poor protection effect.
