[0002] In traditional surveying, methods such as manual on-site measurement are inefficient and limited by difficulties in accessing complex terrains. With the development of drone technology, drones are widely used in surveying work, enabling the rapid acquisition of large-area geographic information data. However, during drone flight surveying, drones are prone to encountering various obstacles such as buildings, trees, and utility poles. Collisions can damage the drone, interrupt the surveying mission, and may even lead to safety accidents.
[0003] Due to the complex environment, current drones are easily damaged by human operation, causing unnecessary losses. It is impossible to guarantee that drone mapping devices can complete mapping tasks safely, stably, and efficiently. Utility Model Content

[0012] Furthermore, the base, enclosure, cover plate, bracket one, and bracket two are made of carbon fiber.
[0013] Furthermore, the sensor is a millimeter-wave radar sensor.
[0014] The beneficial effects of this utility model after adopting the above structure are as follows:
