Low-altitude searching and positioning system

Abstract

The invention discloses a low-altitude searching and positioning system. The low-altitude searching and positioning system comprises a ground ejection device, an aerial reconnaissance device and a ground terminal; the ground terminal sends an ejection angle signal to the ground ejection device, the ground ejection device drives a driving motor according to received angle data, and the driving motor rotates the ground ejection device to a preset angle; the ground terminal sends an ejection confirmation signal to the ground ejection device, the ground ejection device launches the aerial reconnaissance device, the aerial reconnaissance device collects real-time synthetic data and sends the real-time synthetic data to the ground terminal, and the ground terminal receives the synthetic data, performs dynamic image composition and target object recognition and analysis and pushes target objected information. According to the low-altitude searching and positioning system, a sensor is rapidlylifted off in a short time, the target object is prevented from being influenced, and meanwhile, precise ground target positioning is realized; and the size of the aerial reconnaissance device is small, and the aerial reconnaissance device can be carried around, is convenient to recycle, can be reused for several times, and can be applied to scenes of search and rescue after an earthquake, wild animal 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 system. 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...
