Human body security inspection system used for millimeter wave active three-dimensional holographic imaging

Abstract

The invention discloses a human body security inspection system used for millimeter wave active three-dimensional holographic imaging. The system comprises a cylindrical main body frame provided with an outlet and an inlet, a first millimeter wave transceiver and a second millimeter wave transceiver as well as a first millimeter wave switch antenna array and a second millimeter wave switch antenna array which are correspondingly connected; a rotary scanning and driving device is used for driving the first millimeter wave switch antenna array and the second millimeter wave switch antenna array to rotate oppositely; a control device is used for controlling the rotary scanning and driving device as well as the first millimeter wave transceiver and the second millimeter wave transceiver to cause the first millimeter wave transceiver and the second millimeter wave transceiver to respectively carry out parallel cylindrical rotating scanning on area to be scanned in a first scanning area and a second scanning area; and a parallel image processing device is used for synthesizing a three-dimensional holographic image of personnel to be inspected according to acquisition data of the first millimeter wave transceiver and the second millimeter wave transceiver and spatial position information of the acquisition data. By adopting the human body security inspection system used for millimeter wave active three-dimensional holographic imaging, disclosed by the invention, detecting velocity on the personnel to be inspected is improved.

Description

technical field [0001] The invention relates to a human body security inspection system. More specifically, the present invention relates to a human body security inspection system and scanning method based on three-dimensional holographic imaging of millimeter-wave active high-speed cylindrical rotation scanning. Background technique [0002] The urgency of international anti-terrorism has put forward many new demands on human body security inspection. First, it is necessary to be able to realize the non-undressing three-dimensional holographic imaging detection of objects covered by human clothing, so as to improve the efficiency of identifying suspicious objects; second, it is necessary to expand detection capabilities. , can detect metal and non-metal items, including guns, knives, explosives, drugs, CDs, cash, liquids, chips, ceramics, etc.; third, it is necessary to reduce the impact of detection methods on human health on the basis of ensuring the above requirements ...

Problems solved by technology

[0009] However, the existing security inspection systems are all single-switch antenna arrays. Using a single switch array antenna to scan and detect persons to be inspected prolongs the scanning time of persons to be inspected and reduces security inspection efficiency.
