Abstract
The present invention proposes a kind of car plate detection system based on vertical candid camera, the detection system includes a vertical candid photograph camera and a standard bayonet camera, vertical camera installation direction of capturing is perpendicular to track direction, it is vertical to capture wide-angle lens built in camera, for shooting the forward and backward license plate picture of same vehicle, the vertical front and back license plate picture capturing camera and capturing is compared by image-recognizing method, judging candid photograph vehicle, license plate is illegal, front and back license plate is inconsistent with the presence or absence of blocking.The step of image procossing includes: vertical candid camera shooting headstock image；Vertical candid camera shoots tailstock image after specified time interval；License plate in above-mentioned two images is identified；License plate is arrived when unidentified, then filters this result；Fuzzy contrast is carried out to the license plate number in above-mentioned two images, judges whether front and back license plate is consistent；License plate recognition result in above-mentioned two images and the image through processed buckle video camera shooting are synthesized.
Description
Technical field
This programme belongs to car plate detection field, especially a kind of car plate detection system based on vertical candid camera.
Background technique
In the prior art, the monitoring and candid photograph of electronic police, mostly one direction are captured.In face of the number plate that is blocked or preceding
When license plate is inconsistent afterwards, handle relatively complicated.
Summary of the invention
Based on this, a kind of car plate detection system based on vertical candid camera is proposed, the technical solution adopted is as follows:
A kind of car plate detection system based on vertical candid camera, the detection system include a vertical candid photograph camera
It is vertical to capture camera installation direction vertically with lane side with a standard bayonet camera, wide-angle lens built in camera is vertically captured,
For shooting the forward and backward license plate picture of same vehicle, the vertical front and back vehicle capturing camera and capturing is compared by image-recognizing method
Board picture, judging candid photograph vehicle, license plate is illegal, front and back license plate is inconsistent with the presence or absence of blocking.
Further: image processing flow includes:
Step 1: vertical candid camera shoots headstock image；
Step 2: vertical candid camera shoots tailstock image after specified time interval；
Step 3: the license plate in above-mentioned two images is identified；
Step 4: arriving license plate when unidentified, then filter this result；
Step 5: fuzzy contrast being carried out to the license plate number in above-mentioned two images, judges whether front and back license plate is consistent；
Step 6: by the license plate recognition result in above-mentioned two images and the image through processed buckle video camera shooting
It is synthesized.
Compared with prior art, the beneficial effects of the present invention are: detection system include one it is vertical capture camera, vertically
Camera installation direction is captured perpendicular to track direction, it is vertical to capture wide-angle lens built in camera, for before shooting same vehicle,
License plate picture afterwards compares the vertical front and back license plate picture capturing camera and capturing by image-recognizing method, judges that capturing vehicle is
It is no exist block that license plate is illegal, front and back license plate is inconsistent, the smaller difficulty of detection.
Detailed description of the invention
Fig. 1 is detection method flow chart；
Fig. 2 is detection system functional block diagram.
Specific embodiment
In the present embodiment, the car plate detection system based on vertical candid camera of proposition include vertical candid camera and
Standard buckles video camera, wherein vertical video camera uses wide-angle lens, vertical candid camera is used to shoot the front and back vehicle of vehicle
The specific steps of board, car plate detection include:
Step 1: vertical candid camera shoots headstock image；
Step 2: vertical candid camera shoots tailstock image after specified time interval；
Step 3: the license plate in above-mentioned two images is identified；
Step 4: arriving license plate when unidentified, then filter this result；
Step 5: fuzzy contrast being carried out to the license plate number in above-mentioned two images, judges whether front and back license plate is consistent；
Step 6: by the license plate recognition result in above-mentioned two images and the image through processed buckle video camera shooting
It is synthesized.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection scope within.
