Material that millimeter wave is transparent or the material low to millimeter wave reflection coefficient, such as timber etc., coating is sub-light.
Additionally, due to the bright temperature resolution of the single image of general millimeter wave image pickup device is 2K, if human body temperature and
Ambient temperature differs the little millimeter-wave image clearly that just cannot obtain, and people knows from experience " flooding " in the background.Find through experiment, people
Body shell temperature is about 35 DEG C, and limb end (trick) temperature is to being 32 DEG C, when ambient temperature is higher than 26 DEG C, and millimeter wave figure
As starting to become unintelligible, when ambient temperature is less than 24 DEG C, millimeter-wave image is more satisfactory.Therefore, in order to improve tested person
The millimeter-wave image quality of member, it is preferable that placing air temperature regulator 60 in checking passage, such as, air-conditioning, in order to control
Checking the temperature in passage, temperature controls to be advisable at 22 DEG C～24 DEG C, and at a temperature of this, human body sensory is pleasant, mm-wave imaging
Effective, the suspicious item that human body and background and body surface are hidden can be distinguished well.
According to the preferred embodiment of the present invention, owing to needs carry out optical imagery to tested personnel, so needing described
There is the illumination of enough brightness in checking passage, but owing to millimeter wave image pickup device has particular/special requirement to illumination, do not allow directly
Irradiate backboard and mm-wave imaging window, ceiling Gypsum Fibrosum hanging ceiling lamphouse can be used, make light after diffuse-reflectance, then illuminate by
Inspection personnel.
According to a preferred embodiment of the invention, this system can also include being separately positioned on inspection feeder connection, in
Space bar and check the sensor of channel exit, its be used for detecting tested personnel enter inspection passage and tested personnel from
Open inspection passage.
Described sensor can be infrared sensor emitter 501,503,505 and infrared sensor receptor 502,504,
506。
According to a preferred embodiment of the invention, determine that tested personnel place measured zone can have following three kinds of sides
Method: one, by obtaining millimeter-wave image or optical imagery automatic decision tested personnel place measured zone；Two, in described inspection
Infrared sensor is placed at the porch of passage, central dividing plate and exit respectively, as it is shown in figure 1, check the porch of passage
Place infrared sensor emitter 501 and infrared sensor receptor 502, check and at the central dividing plate of passage, place infrared sensing
Device emitter 503 and infrared sensor receptor 504, check that infrared sensor emitter 505 and red is placed in the porch of passage
Outer sensor receptor 506.Utilize the sensor can detect tested personnel and be in the position checking passage；Only in described inspection
Infrared sensor is placed in porch and the exit of looking into passage respectively, and checks and be not required at the central dividing plate of passage place infrared biography
Sensor.
According to a preferred embodiment of the invention, passive millimeter imaging device utilizes the millimeter wave that human body reflects,
Prohibited items in being hidden in human body medicated clothing are detected, human body are injured without ionizing radiation, human body can be carried out body scan,
Image taking speed is 4 width/second.Mm-wave imaging scope (shadow region in Fig. 1) and FOH 1 weight and region be effective human body imaging
District.When tested personnel walk through inspection passage, it is thus achieved that human body Dynamic Millimeter Wave image, and millimeter-wave image information is sent
Process and display to computer system.Meanwhile, also the optical image information of optical imaging device is delivered to computer system
Process and display.
Computer system adopted here is the computer system that millimeter wave process field is conventional, and it is by controlling mould
Block, communication module, software module, algoritic module and display module composition.Control module therein is responsible for computer system and behaviour
Mutual between author, is responsible for obtaining the tested personnel's position signalling from position sensor；Communication module therein is responsible for calculating
Communication between machine system and passive millimeter imaging device, optical imaging device and control module；Software module therein is born
Duty system coordination work；Algoritic module therein is responsible for image procossing and contrast；Display module therein is responsible for the display of image,
Alarm etc..
Millimeter-wave image and optical imagery are processed and contrast by computer system, it is achieved prohibited items in human body medicated clothing
Automatic alarm.
After to the denoising of millimeter-wave image, smoothing, go background, retouch the image procossing such as limit and contrast adjustment, with warp
Optical imagery after process is compared, and the position different with the profile of people in optical imagery is the suspicious region identified, to set
Real-time identification is out for good conspicuous color (such as: shiny red).Fig. 4 is the schematic diagram of image procossing and contrast, is tested personnel
The millimeter-wave image in front and the optical imagery synchronized, millimeter-wave image identifies a ferrum pollard handle hammer held
Son and two suspicious items being hidden in medicated clothing.
Observe for ease of operator, it is also possible to the millimeter wave gray-value image of achromatization is carried out Pseudo Col ored Image, vision
Upper meeting is apparent.
Additionally, described inspection passage can have two kinds of mode of operations, one-man job's pattern and two-handed work pattern.Double work
Operation mode relatively one-man job's pattern percent of pass can substantially double.One-man job's pattern a: people is completely by checking passage the
Two people are allowed for access inspection passage, show the first passive millimeter imaging device and the image of the first optical imaging device, then
Show the second passive millimeter imaging device and the second optical imaging device image, will show on screen when having checked simultaneously
The identity image of tested personnel and back of the body body image.Two-handed work pattern: a people walk out the first passive millimeter imaging device and
Effective imaging area of the first optical imaging device, enters the second passive millimeter imaging device and the second optical imaging device becomes
As district, the second people can enter inspection passage, shows the first passive millimeter imaging device and the first optical imaging device
Image, then show the second passive millimeter imaging device and the image of the second optical imaging device, when having checked on screen
Identity image and the back of the body body image of tested personnel will be shown simultaneously.
Owing to millimeter-wave image and optical imagery are contrasted by needs, therefore to protect when two kinds of imaging devices are installed
Card: in effective areas imaging, the picture size that display demonstrates is roughly the same, simultaneously two kinds of image resolution ratio phases
Join.
Image taking speed >=4 width/the second of millimeter-wave image, the image taking speed >=20 width/second of optical imagery, visually it is
Dynamic image.The walking speed of people is about 1m/s, therefore, before and after tetra-positions of I-I, II-II, III-III and IV-IV
At least 3 width millimeter-wave images can be obtained in the range of 0.8 meter.Every width millimeter-wave image all can find width basic synchronization therewith
Optical imagery.
Although embodiments of the invention being shown and having been described, but it will be understood to those of skill in the art that without departing from
In the case of the principle of the present invention and essence, can change these embodiments, its scope also falls into the right of the present invention and wants
Ask and in equivalent limited range.
