Abstract
Multiple camera suitable for control discernment of parking area parking stall, solved that parking area parking stall video monitoring camera can't obtain because of the input cost is high extensively promoting and the camera because of the unable accurate technical problem who shoots license plate information that deforms, the technical scheme of adoption is: including casing, image gathering module and vehicle license plate recognition module, the key is: vehicle license plate recognition module is last to be equipped with to connect and to be equipped with at least two sets of image gathering module, include in image gathering module's the structure: the optical lens of setting outside the casing, image sensor, the image preprocessing ware be connected with optical lens in proper order, the image preprocessing ware is connected with vehicle license plate identifier respectively. The utility model discloses well video camera covers the parking stall and counts greatly increased, because every camera lens only is directed against single parking stall, so the installation distance of this camera is nimble, can be last to peripheral all parking stalls covers in very short distance.
Description
Technical field
This utility model relates to a kind of multiple camera, belongs to video monitoring and identifies technical field, particularly a kind of multiple camera identified suitable in parking position monitoring.
Background technology
Along with public vehicles extensive development, many Public Parkings such as large scale business body, parking stall quantity and scale are very big.Parking stall quantity is thousands of, and ground or underground divide multilamellar to arrange, if lacking guiding, car owner is stopped cannot be quickly found out room, causes the significant wastage of time and fuel oil, adds discharge and pollutes.But guiding it to be quickly found out parking stall, Car license recognition is precisely that one of them is crucial.
At present the video frequency car position detection photographic head of existing a kind of advanced person, can detect the possession state of parking stall on the one hand, can also identify the license plate number stopped on the other hand.This figure collection and identification device include camera lens, imageing sensor, graphics processing unit and network interface and constitute, and its photographic head is arranged on front upper place, parking stall, is attached by network.Built-in software recognizer, is identified parking space state and the number-plate number, and exports recognition result to host computer, constitutes parking stall and guides or seek car system.
This video frequency car position detection photographic head is progressively applied, and result of use is good.But have a disadvantage in that, one is parking stall high number, if giving the configuration of each parking stall one video frequency car position photographic head, its cost is very high, higher much by mode costs such as ultrasound wave than tradition, thus affects large-scale popularization.If allowing a photographic head by wide-angle lens and high element sensor, 3 or above parking stall be shot and to be identified on the other hand, it is easily achieved principle.But the series of problems still limit product such as in-site installation distance limit, wide-angle lens deform, high element sensor is relatively costly are popularized.Current most of market is that the parking stall measure photographic head used all can only take into account two parking stalls of shooting.Although individual product can shoot three parking stalls, but requires that mounting distance is distant, in-site installation inconvenience.
Summary of the invention
This utility model is solve Parking digital video monitoring photographic head cannot be widely popularized because input cost is high and photographic head cannot accurately shoot the technical problem of license board information because of deformation, devise a kind of multiple camera identified suitable in parking position monitoring, abandon the single-lens Traditional Thinking that multiple parking stalls are shot, but adopt a Car license recognition device, it is simultaneously connected with multiple image acquisition units including camera lens and image pre-processor.One parking stall of each image acquisition units alignment, is responsible for the image real-time acquisition of this parking stall specially and carries out pretreatment.The view data that multiple collecting units export is processed and analyzes by Car license recognition device, circulates identification one by one, and exports state and the license plate recognition result of multiple parking stall, one's respective area to host computer.
This utility model the technical scheme is that for realizing goal of the invention
Suitable in the multiple camera that parking position monitoring identifies, including housing, image capture module and Car license recognition module, it is crucial that: described Car license recognition module is provided with and is connected with at least two group image capture modules, the structure of described image capture module includes: being arranged on the optical lens outside housing, the imageing sensor being connected successively, image pre-processor with optical lens, image pre-processor is connected with Car license recognition device respectively.
In this utility model, each image acquisition units only gathers a parking stall image, and the requirement of camera lens and imageing sensor is substantially reduced, it is not necessary to adopt complicated big wide-angle lens and high pixel image processing sensor, greatly reduces photographic head research and development and production cost.Simultaneously because less costly, it is simple to promote, owing to each camera lens is individually adjustable, it is possible to configure quantity as required, also be able to independent regulation direction at the scene, it is simple to installation and debugging.
In this utility model, video camera covering parking stall number is greatly increased, and owing to each camera lens is just for single parking stall, therefore the mounting distance of this photographic head is flexible, it is possible in very short distance, all parking stalls of periphery are covered.Such as, this photographic head can configure 6 camera lens collecting units, is arranged on directly over double-row parking place center-aisle, arranges parking stall totally six photographic head to two and carries out image taking, is greatly improved level of integrated system, simplifies mounting bracket, and user is very attractive.
Below in conjunction with accompanying drawing, this utility model is described in detail.
