Description

Technical Field

[0001] The utility model relates to the technical field of an unmanned aerial vehicle surveying and mapping lens adjustment mechanism, in particular to an unmanned aerial vehicle surveying and mapping lens adjustment mechanism. Background Art

[0002] At present, drones are often used as carrying equipment for surveying roads, rivers and designated areas to take pictures of the planned areas. Drones do not have a cockpit but are equipped with autopilots, program control devices and other equipment. Personnel on the ground, on ships or at the mother aircraft remote control station use radar and other equipment to track, locate, remotely control, telemeter and digitally transmit the drones.

[0003] However, in the prior art, when aerial photography is performed by a drone, the lens of the drone is generally fixedly installed at the bottom of the drone. Since it is inconvenient to adjust the angle of the lens, the field of view of the photo taken during aerial photography is limited to a certain extent. When the direction and angle of the aerial photography need to be adjusted, the staff is required to operate the drone to adjust the direction and angle of the drone. Therefore, there is a problem that it is inconvenient to adjust the angle of the lens. In addition, in the prior art, it is quite cumbersome to disassemble the lens on the drone. When the lens on the drone needs to be repaired daily, it is quite cumbersome to disassemble the lens on the drone. Therefore, there is a problem that the disassembly of the lens on the drone is relatively cumbersome. In summary, the utility model has the problems that it is inconvenient to adjust the angle of the lens and disassemble the lens on the drone, which is relatively cumbersome. Utility Model Content
