[0002] Geographic information is the geographical meaning contained and expressed by geographic data. It is a general term for numbers, text, images and graphics that represent the quantity, quality, properties, distribution characteristics, connections and laws of materials related to geographical environment elements. UAV aerial surveying and mapping technology is widely used in obtaining geographic, ground and geological information.

[0003] According to the utility model with authorization announcement number CN217994806U, a UAV surveying and mapping data acquisition device is disclosed, including a UAV surveying and mapping body and fixed support legs, the fixed support legs are installed and fixed on both sides of the lower end of the UAV surveying and mapping body, a fixed panel is arranged between the fixed support legs, a gear motor is arranged at the upper end of the fixed panel, a range gear adjuster is arranged on the outer side of the gear of the gear motor, a data acquisition camera is arranged at the front end of the range gear adjuster, and network antennas are arranged on the outer walls of both ends of the data acquisition camera.

[0004] Although the device drives the range gear adjuster to rotate through the gear motor, the range gear adjuster can effectively change the swing direction of the data acquisition camera, thereby effectively changing the overall mapping range, so that the UAV mapping body does not need to change its position for mapping, making the mapping data collection more accurate, but the acquisition camera of the device is fixed on the UAV, which makes it inconvenient for personnel to disassemble and maintain the camera, increasing the complexity of personnel's maintenance operations for the camera, and when the UAV lands or encounters an obstacle, it is inconvenient to store and protect the acquisition camera, which can easily cause damage to the acquisition camera, making it less practical. To this end, we provide a UAV mapping acquisition device to solve the above problems. Utility Model Content
