Description
Technical field
The present invention relates to monitoring technical field, more particularly to a kind of method and system of monitoring parking stall service condition.
Background technology
Modern city, vehicle is more and more, there is the case where many at will parkings, relevant departments are also proposed curb parking
Position, to manage vehicle parking problem, has also just attracted how to manage parking stall problem here.
The method of existing parking position management is to monitor whether parking stall has object by earth magnetism or ground induction coil
It occupying, earth magnetism or ground induction coil are by not stopping paying out the signal sent to determine whether there are the circulation that object blocks signal,
There are objects to occupy parking stall if blocking, and sends message informing patrol officer to manage parking stall, so then every several
As soon as road just needs a people to manage parking stall, and can largely reduce such situation by video camera, as long as administrative staff are at end
End sees that video pictures etc. can understand the parking stall situation at the first time, judges whether to need to scene to be handled, while video
Image data can also protect the equity for the driver for being parked in the parking stall vehicle to a certain extent.
But if using traditional cameras, parking stall can only be monitored by video data, parking stall each in this way needs
It wants someone often to stare at, equally there is certain personnel attrition in this way, so the method that video camera intelligent recognition is proposed in industry, but
Current method is not all suitable for curb parking.
Intelligent recognition algorithm existing for existing market has contour of the vehicle recognizer, Recognition Algorithm of License Plate.
Vehicle appearance recognizer is modeled by the shape for automobile, characteristic statistics, is realized algorithm, is passed through video
Data carry out Algorithm Analysis to image, and analysis parking stall whether there is vehicle.
Recognition Algorithm of License Plate is modeled by the car plate to automobile, and the modes such as font color matching realize algorithm, lead to
It crosses video data and Algorithm Analysis is carried out to image, analyze the number-plate number in image.
Identify that the case where parking stall whether there is vehicle generally may be only available for interior by contour of the vehicle recognizer
Parking lot, shortcoming have：1. requirement of the vehicle identification to image is relatively high, if there is light direct projection vehicle cause it is reflective etc.
The influence of tyre environmental factor can influence its discrimination；2. vehicle identification can only be intelligently the case where facing headstock or the tailstock,
Ability discrimination is relatively high, because the shape all too of vehicle is more, if going to identify from side, the difficulty of modeling greatly improves,
Accuracy is also not ideal enough, and the degree that the public can be supplied to use yet is not achieved in the best standard of industry at present.
It goes to judge whether there is vehicle by Car license recognition, this method is driven into when normal vehicle can when sailing out of parking stall
It can be applicable in, but also have following deficiency：1. None- identified is occupied to vehicle in the case where new car does not have car plate；2. car plate reflective
Very strong, the video shot in the case where there is light direct projection car plate all can't see car plate, can not recognize car plate；3. car plate is known
Not there are problems that car plate and angle lens in the industry cycle, it is too big if there is angle, i.e., it is not that front faces camera lens, car plate exists
Deformation will be identified into not go out accurate car plate when deforming to a certain extent in video imaging.
