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

Embodiment 1

[0023] This embodiment discloses a low-slow target positioning and tracking method based on thermal imaging, such as figure 1 shown, including the following steps:

[0024] S01), two photoelectric turntables equipped with thermal imaging cameras are fixed. The two photoelectric turntables can be on the same level or on different levels. Turntable A and photoelectric turntable B. After fixing, record the latitude, longitude and altitude of A and B, and the straight-line distance between A and B. In order to make the rotation angles of the two photoelectric turntables consistent, it is also necessary to calibrate the north of the photoelectric turntable, and calibrate the true north as the zero point.

[0025] S02), digitize the video image collected by the thermal imaging camera of the photoelectric turntable, and for the convenience of processing, the format of the digitized video image is YUV. For monitoring equipment, such as the video captured by the camera, it is digiti...

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 ...
