Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to an UAV aerial survey target. Background Technology

[0002] UAV aerial survey targets, also known as ground control points, are special markers with known precise coordinates and elevations set up within the survey area. Their core function is to provide absolute positional references for the massive amounts of imagery captured by UAVs, much like "anchor points" for virtual models in the real world. By matching the targets in the images with their real coordinates through post-processing software, the absolute accuracy of the final orthophoto maps, 3D models, and other results can be significantly corrected and improved, transforming them from visually correct models into surveying-grade data that can be accurately measured and analyzed. According to a patent published on the China Patent Network, the patent title is "A Target for UAV Remote Sensing Aerial Survey," patent application number 202420393988.1. It includes a tripod and a target panel. The top surface of the tripod has a threaded hole, and the target panel has a countersunk hole aligned with the threaded hole. A countersunk screw, threaded into the threaded hole, is installed in the countersunk hole. This UAV remote sensing aerial survey target has the advantages of simple structure, ease of manufacture, and low requirements for the operating environment, basically meeting the needs of terrain operations. The UAV remote sensing aerial survey target of this solution has the advantage of high stability and can be used as a ground target and control point for UAV photogrammetry. It is low-cost and ensures the accuracy of image control points to a certain extent. However, the aforementioned aerial survey targets are disassembled for transport, and the disassembly process is relatively troublesome, requiring the screws to be unscrewed by a handle, which takes a certain amount of time, affecting the efficiency of carrying them and making them inconvenient for users.

[0003] Therefore, it is necessary to redesign and modify the aerial survey targets to effectively prevent the slow disassembly and carrying efficiency. Utility Model Content

The knob 6 drives the rotating rod 5 to rotate within the concave frame 4, thereby wrapping the target soft cloth assembly 1 around the surface of the rotating rod 5, achieving the effect of quick roll-up and carrying. Then, when the target soft cloth assembly 1 is completely rolled up, the protrusion 16 will move to the position corresponding to the limiting block 15. Then, rotate the rubbing wheel 11. The rubbing wheel 11 drives the positive and negative thread screw 10 to rotate. The positive and negative thread screw 10 drives the thread block 12 to move inward. The thread block 12 drives the L-shaped plate 13 and the side plate 14 to move inward. The side plate 14 drives the limiting block 15 to move inward, so that the limiting block 15 is engaged inside the limiting groove 20, achieving the effect of positioning it.
