Low-slow target positioning and tracking method based on thermal imaging

Abstract

The invention discloses a low-slow target positioning and tracking method based on thermal imaging, and the method calculates the three-dimensional coordinate information of a moving target based on two calibrated photoelectric turntables and the geometrical relationship between the moving target and the photoelectric turntables, thereby achieving the positioning and tracking of the moving target,and is easy to implement and high in accuracy.

Description

technical field [0001] The invention relates to a low-slow target positioning and tracking method based on thermal imaging, which belongs to the technical field of flying target tracking. Background technique [0002] All objects with a temperature above absolute zero, that is -273°C, will radiate heat, which is often referred to as thermal radiation. Thermal imaging is a technology that uses the thermal radiation of the target to obtain its thermal map. The obtained thermal image is a Pictures of different grayscales can quantify the thermal changes of the target. [0003] With the increasing number of low-speed targets represented by drones in recent years, especially the market blowout of consumer drones, security prevention and control issues such as black flying and terrorist threats have become increasingly prominent, such as In 2017, there was a large-scale suspension of drones at Chongqing Airport, etc. Not only caused bad social impact, but also threatened social ...

Problems solved by technology

In order to obtain accurate three-dimensional coordinates of the target, some systems use a laser range finder to measure the target distance, but because the target is small, far away, and active, especially when there are emergency stops and turns, it is difficult for the range finder Aim the laser at the target, making it difficult to provide accurate 3D coordinates of the target in real time
