X-ray luggage bag inspection system with function of synchronous display of luggage bag shape

Abstract

The invention relates to an X-ray luggage bag inspection system with a function of synchronous display of the luggage bag shape, and belongs to the technical field of radiation imaging. The system is made by adding a visible light luggage bag scanner, a luggage bag sensor, an auxiliary display and radiation protection plates on the basis of an existing X-ray luggage bag inspection system. The auxiliary display faces luggage bag open-package inspection personnel. The radiation protection plates are arranged at the two sides of the entrance and the exit of an inspection channel. The visible light luggage bag scanner is mounted above the entrance of the inspection channel, and scanning data of the visible light luggage bag scanner is input to a computer through a network cable. The luggage bag sensor is mounted above a conveyor belt below the field of vision of the luggage bag scanner, and signals of the luggage bag sensor are input to the computer in the form of switching value. An inspection program built in the computer synthesizes X-ray scanning data of a luggage bag and shape scanning data of the luggage bag column by column, the X-ray scanning data and the shape scanning data are displayed on a main display synchronously, and a suspicious luggage shape image is added with an identifier and then transmitted to the auxiliary display to help open-package inspection personnel to identity and inspect a suspicious luggage bag.

Description

technical field [0001] The invention belongs to the technical field of radiation imaging, and in particular relates to an X-ray luggage bag inspection system capable of synchronously displaying the appearance of luggage bags. It is used at the entrance of airports, stations and important event places to conduct more effective security checks on luggage bags. Background technique [0002] The most commonly used X-ray luggage inspection systems in existence are figure 1 shown. An X-ray array detector 1 is installed on one side of the inspection channel 6 , and an X-ray machine 2 is installed on the corresponding other side, and the fan-shaped X-rays emitted by the X-ray machine are received by the array detector 1 . When the conveyor belt 5 moves the luggage bag 9 to pass through the X-ray, the items in the luggage bag are X-ray perspective, and the perspective data of a row is input into the computer 3, and displayed on its display 4, as seen when luggage bag security check...

AI Technical Summary

Problems solved by technology

However, all these luggage detection technologies show only the X-ray perspective image of the luggage on the computer monitor in front of the inspector; they cannot simultaneously display the shape and color image of the luggage

When the inspector finds that the luggage is suspicious and informs the handling personnel to open the box for inspection, the shape and color of the suspicious luggage cannot be explained; it is difficult to identify exactly from the luggage that passes through the inspection channel

After the luggage bag is moved from the conveyor belt 5 to the waiting platform 8, the processing personnel next to the waiting platform neither know the shape and color of the suspicious luggage b
