Abstract
The present invention relates to a kind of Parking bootstrap techniques based on vehicle secondary identification, when vehicle driving enters parking lot, obtain vehicle license plate picture, identify vehicle license plate number, judge whether it is new vehicle according to license plate number；If new vehicle then recording information of vehicles, and vehicle is set as the second class vehicle, and records its this time parking information；If not new vehicle then calls the history of the vehicle to stop and records, vehicle is classified according to the history parking record inquired, parking water conservancy diversion is targetedly carried out for different types of driver, optimal parking route is sent to display device to show, convenient for vehicle driver target parking stall can be reached according to the optimal parking route of display, the parking efficiency and parking stall utilization rate in parking lot are improved, while reducing parking accident.
Description
Technical field
The present invention relates to a kind of Parking bootstrap techniques based on vehicle secondary identification.
Background technique
At present parking lot management mostly for admission vehicle license plate automatic identification, vehicle admission permission management, from
The functions such as dynamic charging and payment；Vacant parking stall, the guidance of vehicle parking route, vehicle parking are found in inner part of parking lot for vehicle
Safety problem etc. is also lacking, and causing existing parking lot to be found there are parking stall, difficult, vehicle parking is unordered, parking effect
The problems such as rate is low.
And in the prior art, although there is also the parking lot for indicating idle parking stall by display screen, due to can not needle
Specific driver is precisely guided, it may appear that following problems；
1) it when the narrower width of parking stall, wipes and touches between vehicle when being easy to appear parking；
2) major trunk roads or intersection as driver's down time it is too long and caused by parking lot traffic congestion cause to stop
Vehicle inefficiency；
3) it leans on wall or occurring the parking of standdle carrier position or crimping parking at the parking stall of column causes parking resource to waste.
Summary of the invention
The present invention for the technical problems in the prior art, provides a kind of shape that can stop according to the history of driver
Condition carries out stopping guide to stop in improving each vehicle parking efficiency, reducing the parking lot for wiping accident of touching in parking lot between vehicle and draw
Guiding method.
The technical scheme to solve the above technical problems is that the Parking guidance based on vehicle secondary identification
Method, comprising the following steps:
When S1 vehicle driving enters parking lot, vehicle license plate picture is obtained using image collecting device；
S2 carries out image recognition vehicle license plate number according to the license plate picture of acquisition using image processing unit；
S3 Parking management terminal receives the license plate number of identification, and calls the history of the vehicle to stop and record, according to
Vehicle is classified by the history parking record inquired；
S4 determines optimal parking route according to matching vacant parking stall in parking lot the case where vehicle classification；
Optimal parking route is sent to display device and shown by S5, can be stopped according to the optimal of display convenient for vehicle driver
Bus or train route line reaches target parking stall；
S6 stays vehicle from admission to the parking information feedback during complete stop to the storage of Parking management terminal
Shelves.
Further, in step S3, history parking record includes the parking information after each admission of vehicle, is stopped according to vehicle
Vehicle is divided into first kind vehicle and the second class vehicle by vehicle information, wherein the first kind vehicle includes:
Down time is less than the vehicle of preset time；With
After static 1 minute of vehicle image, vehicle's contour does not block the vehicle of any side stop line；
The second class vehicle includes other vehicles other than first kind vehicle.By vehicle according to history parking information point
After grade, vehicle that can be too long by down time and bad stopping technical is distinguished, targetedly into guidance.
It in step S3, is recorded if admission vehicle stops without history, is directly classified as second as admission vehicle for the first time
Class vehicle.
Further, in order to preferably according to all types of parking stalls in vehicle classification situation matching parking lot, institute
State bootstrap technique further include:
Arterial highway number and parking stall peripheral obstacle S0 that the parking space in parking lot is connected according to parking stall width, parking stall
Quantity is divided into the first parking space and the second parking space to parking space；
First parking space includes:
Parking stall width is less than or equal to the parking stall of default parking stall width；
The parking stall that parking stall entrance is connected with major trunk roads；
The parking stall that parking stall entrance is connected at least two arterial highways；
Entrance at least side in parking stall is equipped with the parking stall of at least one barrier；
Second parking space includes remaining parking stall other than the first parking space.
Parking stall in second parking space is relative to the parking stall in the first parking space, for driver
More easily parking storage；And when driver, which needs to take more time, stops, can effectively reduce to major trunk roads and
The duration of congestion of arterial highway intersection improves the whole parking efficiency in parking lot.
Further, in step S5 in vehicle match parking lot vacant parking stall method are as follows:
If admission vehicle is first kind vehicle, nearest vacant vehicle is directly found in the parking space in entire parking lot
Position；If admission vehicle is the second class vehicle, nearest vacant parking stall is first found in the second parking space.
Preferably, if admission vehicle be the second class vehicle, first found in the second parking space not with other the second class vehicles
Adjacent nearest vacant parking stall, to reduce because of driver's technical reason caused by wiping between the vehicle that may cause in parking
It touches.
Further, specific image-recognizing method in step S2 are as follows:
S21 image preprocessing obtains license plate position in image；
S22 is single character the license plate image character cutting of acquisition on the basis of license plate is accurately positioned；
Image information is converted to character information using template matching method by S23, obtains vehicle license plate number.
Preferably, license plate position is obtained using the method that edge detection and Gray Level Jump combine in step S21, by edge
The license plate coordinate that detection obtains mutually is merged with the license plate coordinate that Gray Level Jump method records, it is ensured that the accurate positioning of license plate position.
The beneficial effects of the present invention are:
1) parking space in parking lot is classified, and according to vehicle history parking data in parking lot, for difference
The driver of type targetedly carries out parking water conservancy diversion, improves the parking efficiency and parking stall utilization rate in parking lot, reduces simultaneously
Parking accident；
2) license plate locating method combined by using edge detection and Gray Level Jump, further increases License Plate
Precision prevents the pseudo- license plate of positioning.
