Description

[0001] The present invention relates to a cube-

More particularly, the present invention relates to a cube-type car number recognition apparatus, and more particularly, to a cube-type car number recognition apparatus that rotates in the direction in which a plurality of vehicles enter, captures an image of the car number of each car, Type vehicle identification number recognizing device.

As the social structure becomes more complicated and diversified, the activity area of the individual is gradually widened. Meanwhile, as the movement is required to be prompted, the use of the automobile has been increased in order to facilitate this. Also, due to the development of logistics, the number of vehicles for delivery etc. has increased sharply.

As the number of vehicles increases, the number of parking lots is expected to increase in the future.

At this time, the parking lot is classified into a roadside parking lot installed on a road surface or a certain area of a traffic plaza, an outdoor parking lot installed on a road surface or a place other than a traffic plaza, and a parking lot installed in addition to a facility And these parking lots can be classified as either manned or unmanned.

Here, the incentive system has a problem that excessive staffing costs are incurred because staff members are required to settle the fare, and there is a possibility that a fee is leaked due to the illegal use of the incentive.

And, in the case of a street parking lot, it is not possible to install a fixed fare clearinghouse that controls the entire parking lot, so it may be difficult for an employee to efficiently manage the entire parking lot if the management area is wide.

On the other hand, the most representative example of the unmanned method is a method of managing a parking lot through a license plate recognition device (LPR Device).

The LPR Device is a device for recognizing the vehicle number as text by processing the camera image by photographing the license plate of the vehicle with the camera and analyzing the captured image.

A conventional vehicle identification number (LPR) device first extracts a rectangular license plate object based on digital image information input from an image sensor through a camera that photographs a license plate of a vehicle, And extracts the text secondarily.

The LPR Device extracts text from an image within the visual object based on OCR (Optical Character Recognition) technology.

However, in the conventional vehicle identification apparatus (LPR), a camera for photographing the direction in which the vehicle enters is provided as one, so that the text of the vehicle number of the vehicle entering in one direction is extracted, The number text can not be extracted individually.

Therefore, it is possible to provide a device capable of capturing an image of a car number of a vehicle in which one car number recognition device (LPR) enters in a plurality of directions, respectively, and recognizing letters and numbers of the car number image from a plurality of photographed car number images Development is required.
