System used for avoiding accidentally injuring hostage and automatically tracking and sniping criminal offenders

Abstract

The invention relates to a system used for avoiding accidentally injuring hostages and automatically tracking and sniping criminal offenders. The system comprises a CCD (charge coupled device) detector, an electronic computer, an electric control turnplate, a sniping gun, a sniping controller and an image display, wherein the detector is fixed on the sniping gun, and the sniping gun is fixed on the electric control turnplate; the detector collects images, and people use hands to mark targets (hostages and offenders) on the display; the computer adopts an algorithm which combines a mean-shift algorithm and a particle filtering tracking algorithm to track the hostages and the tracks, an offender picture centre is pulled back to the position concurrent with a site centre through rotating the electric control turnplate, and the offenders are a collimation state all the time; and the computer can calculate the distance between the hostages and the offenders in real time, people judge whether to send a sniping instruction to the sniping controller, and the sniping controller receives the instruction and automatically pulls a trigger. The system provided by the invention can realize the situation that offenders and the hostages can be observed and tracked together, can automatically send out a gunshot instruction under the condition of ensuring of the safety of the hostage safe, and can automatically complete a gunshot action.

Description

technical field [0001] The invention belongs to the technical field of video image automatic tracking and weapon automation, in particular to a system for automatically tracking and sniping criminals for avoiding accidental injury to hostages. technical background [0002] When the public security organs are attacking criminals, when the criminals take hostages, the criminals will often block the hostages in front of them. When the hostages and criminals are blocked, the public security personnel will often negotiate with the criminals. Distance sniper action, the sniper action in the current situation is that the sniper or the machine operator waits for the criminal to emerge from behind the hostage, then artificially observes and judges whether the shooting time is ripe, and then conducts the shooting action, and this shooting action is often caused by personnel psychological Human factors such as nervousness, poor timing of shooting or deviation in aiming, lead to inaccur...

AI Technical Summary

Problems solved by technology

[0003] Purpose of the present invention: the present invention proposes a system for avoiding accidental injury to hostages and automatically tracking and sniping criminals, the purpose of which is to solve the adverse effects on sniping behavior caused by factors such as human psychological tension that existing snipers cannot get rid of when shooting at targets at crime scenes The problem is to realize simultaneous tracking of hostages and criminals, and calculate the distance between the sniping target and the hostages. Under the condition of ensuring the safety of the hostages, that is, the distance is greater than the hostage safety threshold gap T x (manually set), the sniper rifle will automatically shoot criminals
