Security check device and method based on image recognition

Abstract

The invention belongs to the technical field of security check, and particularly relates to a security check device and method based on image recognition. The security check device comprises a mounting frame, the mounting frame is provided with a conveying belt, the mounting frame is provided with a first motor in transmission connection with the conveying belt, the upper side of the mounting frame is provided with a security check bin matched with the conveying belt, and the left side and the right side of the security check bin are provided with entry and exit ports; and a detection and recognition mechanism is arranged on the inner wall of the upper side of the security check bin, the security check bin is in signal connection with control equipment, the security check bin is provided with anti-explosion sealing mechanisms matched with the two entry and exit ports, and a storage module, a central processing module, a display module and an alarm module are arranged in the control equipment. The device is reasonable in design, an intelligent working mode is added on the basis of original artificial checking the color and the contour, workers are assisted to detect articles, when dangerous articles are detected, an alarm is automatically given, and the detection precision is improved.

Description

technical field [0001] The invention belongs to the technical field of security inspection, and in particular relates to an image recognition-based security inspection device and a security inspection method thereof. Background technique [0002] The security inspection machine is also known as the safety inspection instrument. The "golden eyes" of the security inspection instrument are all realized by X-rays. It is an electronic device that sends the checked luggage into the X-ray inspection channel by means of a conveyor belt to complete the inspection. When luggage enters the X-ray inspection channel, it will block the package detection sensor, and the detection signal will be sent to the system control part to generate an X-ray trigger signal, which will trigger the X-ray source to emit X-ray beams. A fan-shaped X-ray beam passing through the collimator passes through the inspected items on the conveyor belt, the X-rays are absorbed by the inspected items, and finally bo...

AI Technical Summary

Problems solved by technology

The detector converts X-rays into signals, and these very weak signals are amplified and sent to the signal processing chassis for further processing. After processing, the images are displayed on the display screen for the staff to view, and the security inspection machine can also monitor radioactivity. Detection, when today's security inspection machines detect items, they will display different colors for different items according to the different materials o
