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

Abstract

The invention provides a multi-mode and multi-target precise tracking device and the method, wherein, a digital servo-platform is used as the support platform; a CCD video camera and an infrared sensor are arranged on the digital servo-platform for receiving image information; the received image information is processed through a comprehensive information process platform for obtaining the tracking information of the target; the tracking information is compressed and transmitted to a control center through a transmission equipment for monitoring. The means that acquiring the target tracking information from the image information is the core of detecting and tracking weak and small targets in complicated background. The method divides and selects the targets through target adaptive threshold based on the binomial distribution judgment rule after pre-processed the image under low signal-to-noise ratio, and then improves the detecting probability of the target and reduces the false alarm probability through data fusion of infrared sensor and visible light sensor, and finally detects and estimates the movement of the selected target to acquire the tracking information of the target. When the target shape is changed, the feature invariant is searched through shape identification of edge feature normalization to realize precise tracking to the target.

Description

(1) Technical field: [0001] The invention relates to a multi-mode multi-target precise 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. The fusion of information realizes detection and tracking of weak and small targets in complex backgrounds, and belongs to the technical field of information processing. (2) Background technology: [0002] In modern warfare, the extensive use of various precision-guided weapons makes air defense operations more and more difficult, and the application of cruise missiles, stealth aircraft, armed helicopters, anti-radiation missiles, reconnaissance and attack drones makes the air defense situation more and more difficult. More and more serious, how to detect the incoming target and carry out an effective attack on it while saving itself is an urgent problem for modern ...

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
