Motion human body safety check imaging system and method

Abstract

The invention belongs to the safety check technology field and particularly relates to a motion human body safety check imaging system and method. The system comprises a synthetic aperture radar (SAR) subsystem, a tracking positioning subsystem and a central processing subsystem, wherein the SAR subsystem is used for carrying out microwave or millimeter wave SAR imaging for a human body in motion, the tracking positioning subsystem is used for tracking and positioning the human body and parts of the human body to acquire the three-dimensional position and attitude information at any time, the central processing subsystem is used for controlling the whole system, processing the acquired data, displaying processing results to users and especially carrying out focusing imaging of the original data acquired by the SAR subsystem through utilizing the position and attitude information of the human body and the parts acquired by the tracking positioning subsystem to acquire SAR images of the human body or the parts. The system is advantaged in that the system aims to realize automatic detection on security threats and prohibited articles carried out by people, and the method is applicable to busy flow public facility and public party and border port occasions.

Description

[0001] field of invention [0002] The invention belongs to the technical field of security inspection, and in particular relates to a system and method for security inspection imaging of a moving human body (including hidden object detection). Background technique [0003] In the current international environment, terrorism is becoming more and more rampant, and terrorist attacks in public places occur frequently. Therefore, anti-terrorism technology has become one of the major international demands. Among them, the security imaging technology for the human body plays an important role, and is mainly used in the monitoring of security threats and prohibited items carried by the human body. [0004] Bombs and weapons carried by the human body are the main threat to public places, and the purpose of carrying them is mostly to carry out terrorist attacks on airports, schools, governments or public gatherings; secondly, carrying prohibited items by the human body through customs...

AI Technical Summary

Problems solved by technology

This directly leads to its narrow application range and low operating efficiency, and is not suitable for public facilities with heavy traffic, public gatherings, border ports, etc.

Moreover, the concealment of the machine itself is poor, and it cannot be detected without the knowledge of the subject.
