Title:
HUMAN BODY SECURITY CHECK SYSTEM AND METHOD BASED ON MILLIMETER WAVE HOLOGRAPHIC THREE-DIMENSIONAL IMAGING
Document Type and Number:
WIPO Patent Application WO/2017/107284
Kind Code:
A1
Abstract:
A human body security check system based on millimeter wave holographic three-dimensional imaging, comprising a mechanical scanning mechanism, millimeter wave signal transceiver units, an image processing unit (7), and an alarm unit (9). The mechanical scanning mechanism is used for driving the millimeter wave signal transceiver units to simultaneously move horizontally and vertically relative to an individual to be checked (10); the millimeter wave signal transceiver units are used for transmitting millimeter wave signals to the individual to be checked (10) and receiving millimeter wave signals reflected by the individual to be checked (10); the image processing unit (7) is used for performing holographic three-dimensional imaging on the body of the individual to be checked (10) according to the reflected millimeter wave signals so as to obtain a three-dimensional image of the body; the alarm unit (9) is used for comparing the three-dimensional image of the body with a three-dimensional image of a secure body pre-stored in the alarm unit (9), and giving an alarm if the three-dimensional image of the body does not match the three-dimensional image of the secure body pre-stored in the alarm unit. The human body security check system is low in costs because electrical scanning is replaced with mechanical scanning, and features a simple structure, a short production period, high resolution, a short imaging time, and wide application. Also provided is a human body security check method based on millimeter wave holographic three-dimensional imaging.
