The invention discloses a
millimeter wave holographic three-dimensional imaging-based
human body security inspection
system and method. The
millimeter wave holographic three-dimensional imaging-based
human body security inspection
system includes an inspection room, a mechanical scanning mechanism, a
millimeter wave transmitting-receiving unit, an
image processing unit and an alarm unit; the mechanical scanning mechanism is used for driving the millimeter wave transmitting-receiving unit to move simultaneously relative to people to be inspected in a horizontal direction and a vertical direction; the millimeter wave transmitting-receiving unit is used for transmitting millimeter wave signals to the people to be inspected and receiving millimeter wave signals reflected from the people to be inspected; the
image processing unit is used for performing holographic three-dimensional imaging on the bodies of the people to be inspected so as to obtain three-dimensional image of the bodies; and the alarm unit is used for comparing the three-dimensional images of the bodies with secure body three-dimensional images pre-stored in the alarm unit, and emitting alarms if the three-dimensional image of the bodies are not matched with the secure body three-dimensional images pre-stored in the alarm unit. According to the millimeter wave holographic three-dimensional imaging-based
human body security inspection
system of the invention, mechanical scanning is adopted to replace electric scanning. The millimeter wave holographic three-dimensional imaging-based human body security inspection system has the advantages of low cost, simple structure, short production period,
high resolution, fast imaging time and wide application.
