Unmanned aerial vehicle patrol and search-and-rescue system based on multi-sensor fusion and search-and-rescue method

Abstract

The invention provides an unmanned aerial vehicle patrol and search-and-rescue system based on multi-sensor fusion and a search-and-rescue method. The unmanned aerial vehicle patrol and search-and-rescue system comprises a signal emitter, an unmanned aerial vehicle search-and-rescue system and a ground rescue center, wherein the signal emitter is arranged on a wearable wristband and is used for sending rescue point position information, and the unmanned aerial vehicle search-and-rescue system and the ground rescue center are used for determining personnel positions and personnel information, recording terrain and determining rescue routes. According to the unmanned aerial vehicle patrol and search-and-rescue system based on the multi-sensor fusion and the search-and-rescue method, a flightsub-control system of an unmanned aerial vehicle is composed of a quad-rotor autonomic unmanned aerial vehicle, an image and quantity acquisition and processing module, a signal transmission module and a terrain analysis and route planning module, and can make fast reaction and collect and analyze image information in real time; and image processing is adopted to perform automatic human body recognition, the recognized information is subjected to data matching with a database, whether target personnel are searched or not is determined, and meanwhile, the number of trapped personnel is determined.

Description

technical field [0001] The invention relates to an outdoor rescue unmanned aerial vehicle system, in particular to an unmanned aerial vehicle patrol search and rescue system and search and rescue method based on multi-sensor fusion. Background technique [0002] With the continuous improvement of living standards, people are getting closer to nature and experiencing nature more and more. However, once they are in trouble in the deep mountains, many people lose their precious lives because of missing the golden rescue time due to the inconvenience of rescue. How rescuers rush to the accident scene as quickly as possible when people encounter danger in the wild, and how to maintain people's lives through some measures is a research direction. The traditional search and rescue method is that firefighters search one by one at fixed points, which has the disadvantages of high risk, high cost of manpower and material resources, and low efficiency.
