Abstract

The invention provides a system and a method for an intelligent unmanned aerial vehicle to grab a target for a high-risk environment. By combining the unmanned aerial vehicle technology, the image processing technology and some mechanical technologies, the unmanned aerial vehicle is applied to foreign matter cleaning work in a high-risk environment. Meanwhile, a plurality of sensors are utilized,and a simultaneous positioning and mapping algorithm, a target detection algorithm and a target positioning algorithm are adopted, so that accurate detection, accurate positioning and stable grabbingof an interested target are realized. Compared with a traditional manual foreign matter cleaning method, the provided method is high in automation degree, high in efficiency and high in safety coefficient and can be widely applied to foreign matter cleaning work in a high-risk environment.

Description

technical field [0001] The invention belongs to the technical field of image processing and unmanned aerial vehicles, and relates to the positioning and navigation of unmanned aerial vehicles in high-risk environments and the detection, positioning and precise grasping technology of targets. Background technique [0002] Over the years, with the rapid development of the tourism industry, the sanitation and cleaning work of the scenic spot is related to the balanced development of the economic and environmental benefits of the scenic spot, and it is one of the problems to be solved urgently in the scenic spot. However, in some steep scenic spots, such as cliffs, sanitation work becomes very dangerous. In addition, on some overhead power lines, the cleaning of foreign matter is also a very difficult task. [0003] With the continuous advancement of drone technology, its strong flexibility of manipulation and high scalability of functions are gradually favored by the public. C...
