Technical Field

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

[0002] When some engineering projects are carried out, it is necessary to survey and map the site, but the traditional surveying technology can no longer meet the current needs. The basic control points are not easy to save, the hidden points are difficult to measure, the cumulative measurement errors are large, the work is repeated, and the efficiency is low. Therefore, people began to choose drone surveying. Drone surveying technology is currently subverting the traditional surveying method because of its advantages of fast and efficient, flexible and low cost, and has become a "familiar" in the surveying and mapping industry.

[0003] During the surveying and mapping process, existing UAVs need to be equipped with surveying lenses. When the UAV is flying, the surveying lenses can survey the site that needs to be surveyed below the UAV. However, the number of surveying lenses of existing surveying and mapping UAVs is fixed. Since the sites that need to be surveyed by the UAV are not fixed, the conventional number of surveying and mapping lenses is difficult to adapt to a variety of environments. Therefore, it is not convenient to improve the surveying and mapping effect of the surveying and mapping UAV and to conduct surveying and mapping in different sites.

[0004] The existing Chinese patent with announcement number CN218704013U discloses a lens mapping UAV, including a UAV body, wherein the UAV body is provided with fan blades at the four corners, a bracket is provided at the bottom of the UAV body, a mounting plate is provided on the bottom surface of the UAV body and the inner side of the bracket, and a mapping component is provided at the bottom of the mounting plate; the mounting plate is cross-shaped, the mounting plate is provided with four protruding sections, and the side of the mounting plate is provided with a plurality of mounting plates connected with screws of the UAV body, the bottom surface of the protruding section is provided with a mounting groove, the mounting groove is T-shaped, and a data connection strip is provided on the inner top surface of the mounting groove, and the mapping component includes an assembly plate, an assembly block, a first mapping lens and a second mapping lens.
