Embodiment Construction

[0048] Such as figure 1 As shown, the present invention discloses a low-altitude search method, which is based on an aerial detection device, which can cleverly avoid the shortcomings of obstacle barriers during ground detection, and has a fast lift-off speed, low noise, and a large volume. It is small and can be carried with you, suitable for emergencies or emergencies, and suitable for low-altitude detection.

[0049] Such as Figure 8 As shown, the method includes:

[0050] The S1 aerial detection device confirms the detection environment, adjusts the launch angle of the ground ejection barrel, and the ground ejection device ejects the aerial detection device into the air;

[0051] S2 Acquire the current comprehensive data of the aerial detection device, the comprehensive data includes the motion posture information of the aerial detection device itself, the relative position information of the aerial detection device, the depth map and the thermal imaging map around the ...

Abstract

The invention discloses a low-altitude searching and positioning method, which includes the following steps: (1) after the detection environment of an air detection device is confirmed and the launching angle of a ground ejection gun barrel is adjusted, ejecting, by the ground ejection device, the air detection device into the air; (2) acquiring current comprehensive data of the air detection device, wherein the comprehensive data comprises motion posture information of the air detection device, relative position information of the air detection device, a depth map and a thermal imaging map around a target object; (3) receiving, by a ground terminal, the comprehensive data, preforming dynamic image synthesis and target object identification analysis, and pushing target object information.According to the method, a sensor is rapidly lifted off in a short time, so that the sensor can be used for emergency events, and accurate ground target positioning can be realized while the target object is prevented from being influenced; and the air detection device is small in volume, portable, convenient to recycle and reusable, and can be applied to scenes such as post-earthquake search andrescue, wildlife protection, criminal investigation, flood rescue and the like.

Description

technical field [0001] The invention relates to the technical field of aerial detection, in particular to a low-altitude search and positioning method. Background technique [0002] The traditional detection devices are mainly: to obtain the position information of the target object from the ground through ultra-low frequency radio waves or electromagnetic induction technology, of which ultra-low frequency radio waves are mainly used for life detectors, and electromagnetic induction is mainly used for metal detectors, but the detection range of ground detection devices Limited, and easily blocked by obstacles; UAVs equipped with infrared sensing devices or airborne radars are used to obtain target location information from the air, but UAVs are slow to lift into the air, have poor timeliness, and are prone to huge The noise disturbs the target. [0003] The cost of airborne radar is higher, and it is more inclined to the military field. It is not suitable for close-range pr...
