Security check system capable of recognizing prohibited articles based on ray technology and deep learning

Abstract

The invention relates to a security check system capable of recognizing prohibited articles based on the ray technology and deep learning, and the system is characterized in that the system comprisesa nuclear density meter, a spectrum analyzer, an X-ray security detector, a GPS module, a wireless communication module, a microcontroller, a power module, an alarm module, and a display module; the X-ray security detector stores a collected X-ray transmission image and corresponding image position information in the image storage module, and the function of the microcontroller is to realize the segmentation of an article image and recognize whether a sub-image is an image of a suspicious prohibited item or not, so as to facilitate further identification and confirmation; the wireless communication module realizes the communication of the nuclear density meter, the spectrum analyzer and the X-ray security detector with the microcontroller. The structure chart of a designed security check device consists of a conveyor belt (1), a device housing (2), a ZA150180 channel X-ray machine (3), a DensityPRO (4), a CMS-2S fast spectrum analyzer (5), and an alarm (6). The system achieves the recognition of the suspicious prohibited item through the knowledge of deep learning, and then combines with the nuclear density method and the spectrum imaging technology for further confirming the suspicious prohibited item.

Description

Technical field [0001] The invention relates to the technical field of safety inspection, in particular to a security inspection system for identifiable contraband based on ray technology and deep learning. Background technique [0002] In order to ensure the personal safety of passengers, airports and railways have installed security inspection systems and equipped with advanced baggage inspection machines. The baggage is placed on the conveyor belt and then inspected by X-ray equipment. The end of the ray source emits a beam of processed fan-shaped X-rays that pass through the inspected object. The effects of X-rays absorbed by different inspected items are different. The bombardment energy semiconductor detector is converted into signals and further processed. Finally, the perspective image is observed on the screen. The images of different colors represent different substances. [0003] At present, the security check mainly combines the image output by the security check mach...

Problems solved by technology

[0003] At present, the security inspection is mainly based on the image output by the security inspection machine to manually judge whether it is a contraband, and there are problems of long time consumption and low efficiency of security inspection.
