According to the utility model preferred embodiment; The passive millimeter wave imaging device utilizes the millimeter wave of human body reflection, and prohibited items detect in the human body clothing to being hidden in, and human body is not had the ionising radiation injury; Can carry out body scan to human body, image taking speed was 4 width of cloth/seconds.Mm-wave imaging scope (shadow region among Fig. 1) and FOH 1 heavy and the zone be effective human body imaging area.During passage, obtain the dynamic millimeter-wave image of human body through inspection in seized personnel's walking, and millimeter-wave image information is delivered to computer system process and display.Simultaneously, also the optical image information of optical imaging device being delivered to computer system processs and displays.
Here the computer system that has adopted is a millimeter wave process field computer system commonly used, and it is made up of control module, communication module, software module, algoritic module and display module.Control module wherein is responsible for mutual between computer system and operator, is responsible for obtaining the seized personnel's position signalling from position transducer; Communication module wherein is responsible for the communication between computer system and passive millimeter wave imaging device, optical imaging device and control module; Software module wherein is responsible for system coordination work; Algoritic module wherein is responsible for Flame Image Process and contrast; Display module wherein is responsible for the demonstration of image, alarm etc.
Computer system is handled and is contrasted millimeter-wave image and optical imagery, realizes the automatic warning of prohibited items in the human body clothing.
Through to the denoising of millimeter-wave image, level and smooth, go background, retouch Flame Image Process such as limit and contrast adjustment after; Compare with optical imagery after treatment; With the different position of people's in the optical imagery profile be the suspicious region that identifies, with the conspicuous color that configures (such as: shiny red) sign is come out in real time.Fig. 4 is the synoptic diagram of Flame Image Process and contrast, is positive millimeter-wave image of seized personnel and synchronous with it optical imagery, has identified an iron pollard handle hammer of holding and two suspicious items that are hidden in the clothing on the millimeter-wave image.
Observe for ease of the operator, can also carry out pseudo-colours to the millimeter wave gray-value image of achromatization and handle, visually can be more clear.
In addition, said inspection passage can have two kinds of mode of operations, one-man job's pattern and two-handed work pattern.The two-handed work pattern can roughly double than one-man job's pattern percent of pass.One-man job's pattern: a people is fully through inspection passage second people inspection passage of being allowed for access; The image that shows the first passive millimeter wave imaging device and first optical imaging device; Show the second passive millimeter wave imaging device and the second optical imaging device image again, will show seized personnel's identity image and back of the body body image when having checked on the screen simultaneously.The two-handed work pattern: a people walks out effective imaging area of the first passive millimeter wave imaging device and first optical imaging device; Get into the second passive millimeter wave imaging device and the second optical imaging device imaging area; Second people can get into the inspection passage; The image that shows the first passive millimeter wave imaging device and first optical imaging device; The image that shows the second passive millimeter wave imaging device and second optical imaging device again will show seized personnel's identity image simultaneously and carry on the back the body image on the screen when having checked.
Because need compare millimeter-wave image and optical imagery, therefore when two kinds of imaging devices are installed, will guarantee: in effective imaging scope, the picture size that demonstrates on the display is roughly the same, and two kinds of image resolution ratios are complementary simultaneously.
The image taking speed of millimeter-wave image >=4 width of cloth/seconds, the image taking speed of optical imagery >=20 width of cloth/seconds visually is dynamic image.People's walking speed is about 1m/s, therefore, in the 0.8 meter scope in the front and back of I-I, II-II, III-III and four positions of IV-IV, can obtain at least 3 width of cloth millimeter-wave images.Every width of cloth millimeter-wave image all can find the width of cloth optical imagery of basic synchronization with it.
Although the embodiment of the utility model is showed and describes; But it will be understood to those of skill in the art that under the situation of principle that does not depart from the utility model and essence; Can change these embodiments, its scope also falls in the claim and equivalent institute restricted portion thereof of the utility model.
