An unmanned aerial vehicle life detection method and system based on a multi-source sensor

Abstract

The invention discloses an unmanned aerial vehicle life detection method and system based on a multi-source sensor. The method comprises the steps that S1, an unmanned aerial vehicle carries a multi-source sensor to detect and search a target area, and the multi-source sensor comprises a radar sensor used for detecting a radar image, a visible light image sensor used for collecting a visible lightimage and an infrared thermal image sensor used for collecting an infrared image; S2, signals detected by the sensors are received and fused, and an area with a life detection target in the target area is obtained according to a fusion result; The system comprises a detection search module and a multi-source information fusion module. Rapid and accurate life detection within a large range can beachieved based on the unmanned aerial vehicle, the application range is wide, and flexibility and environmental adaptability are high.

Description

technical field [0001] The invention relates to a wide range of technical fields of life detection and rescue, in particular to a multi-source sensor-based UAV life detection method and system. Background technique [0002] When large-scale natural disasters such as earthquakes and landslides occur, it is urgent to quickly detect and search for the specific location of the trapped buried people in order to organize rapid rescue. At present, life detection radar is usually used as a search device, but life detection radar needs to be manually checked point by point in the search area. Life detection radar can penetrate non-metallic obstacles such as shrubs, grass, shallow floating soil, and building ruins. Detect the vital signs of the human target below it, but the area that can be detected is limited. It is usually suitable for human target search and detection in the case of ruins, shallow soil / debris / floating grass burial, and for dangerous collapsed buildings due to the ...

Problems solved by technology

This type of method uses the UAV to judge the location of the person in distress through the directional antenna. The actual detection accuracy is still not high, and the information of the person in distress is judged only by the strength of the wireless signal. The source of the signal cannot be distinguished, and the probability of misjudgment is high. It is difficult to achieve fast and accurate scanning in a wide range
