Multi-module and multi-target accurate tracking apparatus and method thereof

Abstract

The invention provides a multi-mode multi-target precision tracking device and method. The device uses a digital servo platform as a supporting platform, and the image information obtained by a CCD camera and an infrared sensor placed on it is processed by a comprehensive information processing platform to obtain a target. The tracking information is sent to the control center for monitoring through compression and transmission equipment. The method of obtaining target tracking information from image information is the core of weak target detection and tracking in complex backgrounds. After preprocessing the image under low signal-to-noise ratio, the method uses the target adaptive threshold based on the binomial distribution judgment criterion. Segment and extract the target, and then improve the detection probability of the target and reduce the false alarm probability through the fusion of infrared and visible light sensor data. Perform motion detection and estimation on the extracted target to obtain its tracking information. When the shape of the object changes, shape recognition using edge feature normalization finds feature invariants to achieve accurate tracking of the object.

Description

(1) Technical field: [0001] The present invention relates to a multi-mode and multi-target precision tracking device and method, in particular to a device and method for pattern recognition and intelligent control, automatic target detection and recognition technology under complex background, image processing and data fusion, through visible light and infrared The fusion of information realizes the detection and tracking of weak and small targets in complex backgrounds, and belongs to the field of information processing technology. (two) background technology: [0002] In modern warfare, the extensive use of various precision-guided weapons has made air defense operations more and more difficult. The application of cruise missiles, stealth aircraft, armed helicopters, anti-radiation missiles, reconnaissance and attack drones has made the air defense situation more and more difficult. How to detect the incoming target and carry out an effective attack on it while saving ones...

AI Technical Summary

Problems solved by technology

At present, my country's air defense system is mainly established against conventional aircraft, so the ability to resist the above-mentioned targets is relatively weak, the main reason is that there are difficulties in the detection of the above-mentioned targets

In particular, the threat of anti-radiation missiles greatly restricts the application of air defense radars

According to reports, before the Iraq War in 2003, more than 80% of Iraq's air defense system was intact, but after the war broke out, Iraq's air defense weapons were almost useless. In his hands, as long as the Iraqi army's air defense radar is turned on, it will be attacked by the US anti-radiation missile within a few minutes. While destroying the Iraqi air defense system, the US army also destroyed the Iraqi army's will to fight. Therefore, although most of the Iraqi army's air defense weapons are intact It is non-destructive, but dare not use it, and becomes a pile of useless scrap iron

The main reason why the Iraqi air defense operations failed to function effectively is the lack of effective means of detection against US air threats
