The Research About The Database And Query Method Of Vehicle Security Supervisory System

Nowadays, with the popularization of the automobile, the persons are attached much importance to the vehicle security supervisory device. The terrorist organization is so rampant that the automobile explosion unceasingly happened all of the world. In order to safeguard the society be stable, make the lives and the possessions be safe, all of the countries reinforce the security monitoring measure. The terrorists often hide the explosion in the bottom of the automobile to avoid being in sight. Also, some people are hidden in the bottom of the automobile to enter some country illegally. So the bottom examination of the automobile becomes an important part in the security supervisory. But nowadays, in our country, any effectual and credible intelligent vehicle security supervisory system has not appeared.Aiming at the problems existing in the traditional Vehicle Security Supervisory System (VSSS), in this paper, an intelligent VSSS is proposed; firstly presenting the basic theory of the system; then comparing with the other methods and analyzing the special characteristics of the mobile vehicle; taking the line scan technology to get the images of the vehicle bottom, then transferring the images to the server. Then some database designing methods are introduced in this paper. And an image database is set up in the server including the vehicle information management, the user information management and etc. Also, this paper analysed some data index methods, implemented the data index on the vehicle license and run the program based on the time index.In the last, the system is tested, and the results indicate that the system is effectual and credible. A vehicle instrument are deviced to detect the automobile, then the system will grab the vehicle image through the image grabber.The image will be stored after pre-processing.This system makes use of the advanced computer vision, making the scan of the bottom of the vehicle, the network transmission and the image index one, Under the condition of guaranteeing reliability, the system can greatly increase the bottom inspection's automation and will be widely used in these areas such as the customs, the airports and the military branches.
