Intelligent vehicle safety vision detection device and motion target tracking method

Abstract

The invention discloses an intelligent vehicle safety vision detection device and a motion target tracking method. The system mainly comprises a vehicle detection device, a vehicle bottom image scanning device, a license number image acquiring and recognizing module, an image compression and transmission module, an image database module, a main control computer, a box body and the like. The top of the box body is provided with toughened glass, the vehicle bottom image scanning device is arranged below the toughened glass, a camera is connected with the main control computer through a video data output line, wherein the main control computer is internally provided with an image acquiring card; and the intelligent vehicle safety vision detection device is also provided with a license number image acquiring and transmitting part. Meanwhile, a multi-motion target detection and tracking method based on self-adaption nonparametric nuclear density estimation is designed in the invention. The invention has high automatism, high detection speed and wide adaptability, and can realize non-parking detection.

Description

technical field [0001] The invention mainly relates to the field of intelligent vehicle safety detection, in particular to a vehicle safety visual intelligent detection device and a moving target tracking method suitable for important places such as customs, military bases, large conferences, and aviation departments. technical background [0002] In today's world, cars are becoming more and more popular, and people are paying more and more attention to safety monitoring measures for vehicles. In particular, car bombings continue to occur in various places, and the activities of terrorist organizations are becoming more and more rampant. In order to ensure social stability and the safety of people's lives and property, countries have stepped up security monitoring measures for customs, airports, government departments, military bases and other important places. Terrorists mostly hide explosives under cars to avoid inspectors' sight. In addition, many illegal immigrants als...

Problems solved by technology

Although this kind of under-vehicle security inspection robot has been greatly improved compared with the hand-held under-vehicle security inspection mirror, the shortcomings of this detection method are: (i) the vehicle to be inspected needs to be stopped for inspection; (ii) the obtained image information may Incomplete, there will be places that the car has not traversed; (iii) The inspection takes a long time, and the time for a small car to be inspected is as long as 6 to 8 minutes

[0006] At present, domestic scientific research institutes have developed a similar security inspection system based on machine vision. Its price is relatively low, but its function is only to use the camera to capture the video information of the bottom of the vehicle when the car passes through the security checkpoint, and display it on the spot. on the server, there is no file storage function

Moreover, because what is displayed is the dynamic video of the bottom of the car, not the image of the bottom of the car, so it is very likely that some very important information will be missed due to the speed of the car or the inattention of the staff during the monitoring. The effect of security inspection in important places such as customs is very unfavorable

And the range of the vehicle bottom that the system can capture is only 1.3 meters, and the detection speed can only reach 0.3 meters per second

Products in foreign markets have improved functions, but still have defects such as high cost and poor scalability.
