Example Embodiment

[0032] The following further describes the present invention with reference to the accompanying drawings of the specification and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0033] Such as figure 1 As shown, the steps of the UAV life detection method based on multi-source sensors in this embodiment include:

[0034] S1. Detection and search: The drone is equipped with multi-source sensors to detect and search the target area. Multi-source sensors include radar sensors for detecting radar images, visible light image sensors for collecting visible light images, and infrared images for collecting infrared images. Thermal image sensor

[0035] S2. Multi-source information fusion: the signals detected by each sensor are respectively received and fused, and the fusion result determines the area where the life detection target exists in the target area.

[0036] Multi-source information fusion is to use computer technology to d...

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 ...
