Important front edge research field, plays very important effect, and extensive use will facilitate China's automatic traffic management
Process.
And existing road Car license recognition camera is arranged at height in the air at present, is arranged such when acquiring video information not
It is only easy to be influenced by road both sides vegetation, and is difficult to acquire view in the weaker place of night light or while having greasy weather gas
Frequency information is inconvenient in addition, also needing to be arranged higher bracket when such camera is arranged for its placement.
Utility model content
In view of the above shortcomings of the prior art, the utility model provides a kind of road Vehicle License Plate Recognition System device, including
Road, video acquisition device and vehicle identifier, the video acquisition device include camera, radio transmitting device, upper cover
And pedestal, wherein the video acquisition device is set in the road by embedded mode.
Further, the video acquisition device is rectangular prismatoid structure.
Further, the camera is set on the inclined-plane of the video acquisition device rectangular prismatoid.
Further, headlamp is additionally provided on the camera.
Further, the vehicle identifier includes license plate retrieving module, image processing module and Car license recognition mould
Block.
Further, the upper cover is double-layer structure, and the double-layer structure includes buffer layer and protective layer.
Further, the buffer layer is rubber layer, and the protective layer is aluminium alloy layer.
Further, the radio transmitting device is wireless bridge.
The utility model has the following beneficial effects: the utility model by video acquisition device by insertion by way of be arranged
In on the road of motor-driven vehicle going, not only can influence to avoid road both sides vegetation to video acquisition, but also due to so setting
The camera set is closer apart from vehicle, effective video can be carried out under the weaker environment of light or under foggy weather and adopted
Collection, improves the accuracy of video acquisition.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings.
Fig. 1 is the overall structure diagram of the utility model video acquisition device.
