Description
Technical field
The utility model is related to a kind of green logical vehicle detecting system containing linear array imaging device, belongs to communications and transportation operation pipe
Reason technology technical field.
Background technology
Area array cameras imaging technique is used on existing market on same category of device, by limitation of the technology reason, area array cameras
Industry scanning is extremely difficult to the scanning requirement to strip moving object, the technology is in the longer dynamic object of scan size
Shortcoming clearly, is limited by the imaging area of area array sensor, industrially tends not to reach that Polaroid energy is complete
Scanning whole object image, so having to be imaged several times and then being spliced into the complete subject image of a width, shortcoming
It is that sum of all pixels is more, and the pixel of the pixel ratio linear array imaging in every row is few, image is negatively also restrained, so ultimately resulting in
Image volume is bigger than normal, and imaging resolution is low, and device structure is complicated, and cost is high, and is unable to real time imagery, speed in scanning
Slowly.
The content of the invention
In order to overcome the drawbacks described above of existing area array cameras imaging technique, the purpose of this utility model is to provide one kind and contained
The green logical vehicle detecting system of linear array imaging device, to improve the resolution ratio of imaging, reduction imaging cost is high, realizes in scanning just
Can real time imagery.
To realize its purpose, the technical solution adopted in the utility model is：That designs is green logical containing linear array imaging device
Vehicle detecting system, including：Image device, CPU computers and position feedback device, wherein the image device uses CMOS linear arrays
Row ccd detector, the setting height(from bottom) of the detector is more than 2.4 meters, and AD conversion precision 16, resolution ratio is less than 1.5mm, signal to noise ratio
More than 4000db, data are quickly transmitted using ICP/IP protocol kilomega network, supply voltage is DC6-12V.
Compared with prior art, the utility model has following features and progress：
1st, line array CCD adds sweep mechanism and position feedback loop section, and its cost is significantly less than same homalographic, equal resolution ratio
Area array CCD；
2nd, the coordinate of scan line is provided by grating, and the indicating accuracy of high-precision grating scale can be higher than between area array CCD pixel
Away from the accuracy of manufacture, in this sense, the image precision in a scanning direction that line array CCD is obtained can be higher than area array CCD
Image；
3rd, because the splicing of line array CCD sub-pixed mapping described in the utility model is using online by the pixel of two panels CCD chip
1/2 pixel of mutual dislocation is allowed to optical method on the spread length direction of battle array, it is by second CCD all pixels
In the pixel gap for being sequentially inserted into first CCD, indirect " reduction " line array CCD pixel dimension improves CCD resolution ratio, delayed
Solve due to being difficult the problem for reducing CCD pixel dimensions by technique and Effect of Materials, the resolution higher than area array CCD can be obtained
Rate and precision；
4th, the characteristic of line-scan digital camera meets the scanning of large-scale low speed mobile object very much, can especially make vehicle by sweeping
Retouch in detection process, it can be seen that the clear scanned photograph formed in real time, convenient and swift, image clearly, be swift in response, Ke Yitong
The many ground of network implementation are crossed while showing result, convenient monitoring and examination ＆ verification, efficiency is improved；
5th, old of linear camera it is cheap, it is simple in construction, be easy to the production system of equipment.
Brief description of the drawings
Fig. 1 is structural representation block diagram of the present utility model.
Wherein：1st, image device, 2, computer, 3, position feedback device.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：
Referring to the drawings, the green logical vehicle detecting system containing linear array imaging device designed, including：Image device 1, CPU
Computer 2 and position feedback device 3, wherein the image device 1 uses CMOS linear array CCD detectors, the installation of the detector
Highly it is more than 2.4 meters, AD conversion precision 16, resolution ratio is less than 1.5mm, signal to noise ratio is more than 4000db, uses ICP/IP protocol

The pixel of piece is allowed to 1/2 pixel of mutual dislocation on the spread length direction of linear array with optical method, by second CCD's
All pixels are sequentially inserted into first CCD pixel gap, indirect " reduction " line array CCD pixel dimension, to improve CCD's
Resolution ratio, alleviates due to being difficult the problem for reducing CCD pixel dimensions by technique and Effect of Materials, can obtain than area array CCD more
High resolution ratio and precision.The CPU computers 2 use existing computer, the position feedback device 3 include conventional display and
Barrier machine.
During work, the linear array CCD detector of image device 1 is arranged on the porch of a green monitoring station that is open to traffic, and works as automobile
Into monitoring station porch when, linear array CCD detector is scanned to the vehicle of entrance, is passed image-forming information by wire
Image procossing is carried out to CPU computers 2, then includes image and its result on the display of position feedback device 3.
