Matching system of violated vehicle for hi-pass road}

According to the present invention, when a vehicle passing through the toll section is detected, a unique key value is generated and assigned to the detected vehicle, and the image and vehicle numbers obtained by photographing the front and rear sides of the detected vehicle are matched with the generated key value. The present invention relates to a high-pass multi-vehicle matching system that has excellent matching rate between front and rear images and vehicle number, and has excellent vehicle recognition detection accuracy.

In general, a method of collecting a fare for a vehicle by installing a toll gate or a card issuing device in the vicinity of an access road entering a fare collection section is used for roads where charges due to road driving such as highways and bridges are collected.

This conventional toll collection method is expensive due to waste of manpower or one-time card production, and traffic congestion is severely generated because it causes a vehicle stop at the waiting point of the settlement or issuing device. Accordingly, various studies on unmanned toll collection systems and methods for reducing the speed reduction of vehicles without the use of manpower or one-time cards have been developed and commercialized.

1 is a block diagram showing a conventional toll collection system disclosed in Patent No. 10-0839264 (name of the invention: open toll gate toll collection system and method).

As shown in FIG. 1, the conventional toll collection system 100 has vehicle model information and smart card information, and the vehicle mounting apparatus 101, which can transmit the information independently, and the vehicle mounting apparatus 101 pass through. From the roadside base station 103 which communicates wirelessly for toll collection, the vehicle class classifier 105 for classifying vehicle types by scanning the width, length, height, etc. of the vehicle, and the roadside base station 103 and the vehicle class classifier 105 A charge settlement terminal controller 107 that receives the information, calculates and processes a toll, a vehicle photographing apparatus 109 for photographing a vehicle according to a command of the charge settlement terminal controller 107, and a charge controller terminal controller; It is connected to the upper network 111 for the database update and management, and the like.

The conventional toll collection system 100 configured as described above is automatically charged through wireless communication between the vehicle-mounted device mounted on the vehicle passing through the toll gate and the roadside base station installed in the toll gate using an active short-range wireless dedicated communication system. As a result, the vehicle does not have to stop to pay a fee, thereby reducing oil cost, vehicle delay, and waste of manpower.

However, in the conventional toll collection system 100, the customer must bear the cost of installing a vehicle mounting apparatus 101 capable of transmitting and receiving a signal with a wireless signal receiver in a vehicle for toll collection, and photographing a license plate of the vehicle. If the device 109 is formed only in one direction and photographing is not performed properly due to the surrounding environment or unexpected situations, a problem arises in that it cannot provide any basis for toll collection.

In addition, the conventional toll collection system 100 cannot obtain the image information when the vehicle changes lanes or weaves while the photographing apparatus 109 is being photographed. Therefore, the toll collection system 100 cannot provide a basis for future toll collection. Is generated.

In addition, in order to overcome the problems of the toll collection system 100 to which the unidirectional imaging device 109 is applied, the toll collection system 100 to which the imaging device 109 is photographed before and after the driving vehicle has been studied and used. .

2 is a configuration diagram illustrating a conventional bidirectional monitoring system.

It can be provided.

However, the conventional bidirectional monitoring system 200 compares the vehicle image when one of the first camera 203 and the second camera 205 photographing the front and the rear of the vehicle 202 temporarily has a shooting error. Since it becomes impossible itself, a problem arises in that an image cannot be acquired, as in the one-way toll collection system 100 of FIG. 1.

In addition, the conventional bidirectional monitoring system 200, if one of the first camera 203 and the second camera 205 is temporarily shooting error occurs, the image corresponding to the error-free camera is generated image In order to match the image, it is necessary to compare the images directly through the manpower, which is not only cumbersome but also delays work time.

In addition, the conventional bidirectional monitoring system 200 accurately detects the vehicle area within the images of the first camera 203 and the second camera 205, and compares their sizes to extract a still image in real time. Not only does it require work, but the error rate increases.

In addition, since the size of the vehicle, such as small, medium, large and trucks are similar, the conventional two-way monitoring system 200 recognizes different vehicles as the same vehicle when the vehicles of the similar size is running, the detection accuracy is lowered.

In addition, the conventional bi-directional monitoring system 200 is the camera 203, when the vehicle driver recognizes the first camera 203 and the second camera 205 in advance to change the lane at the location of the so-called cameras 203, 205 There is a problem in that image information cannot be obtained.

In addition, the face removal controller 5 matches the front image information and the rear image information corresponding to the front vehicle number if the front number and the rear number match, and transmits the matched vehicle number to the lane controller 7.

That is, the face removal controller 5 detects the rear vehicle number by analyzing the advancement image information transmitted from the camera control apparatus 4, and then searches the previously stored front vehicle number to extract the front vehicle number that matches the detected rear vehicle number. As a result, the front image information and the rear image information of one vehicle 10 are matched. At this time, the face removal controller 5 is a matching vehicle number, the key value 20 (driving detection unit (2-1), ..., (2-N) corresponding to the vehicle number, advance detection unit (3-) 1), ..., generated by the sensing of each of (3-N)) to the lane controller 7.

Also, the face removal controller 5 transmits the front image information and the rear image information to the image server 8 when the front vehicle number and the rear vehicle number match.

In addition, the face removal controller 5 may use the front cameras 42-1, ..., (42-N) or the rear cameras 41-1, ..., (41-N) according to the external environment and sudden situations. ) If the vehicle number is not recognized properly because they do not acquire the correct image, the data except the vehicle number is stored in the temporary memory, and when the data is matched, the remaining unmatched data is created as a candidate list of the data stored in the temporary memory. The candidate list is transmitted to the video server 8.

For example, when the vehicle driving the toll section S is a generation ('A', 'B', 'C'), the rear cameras 41-1, ..., (41-N) When the image of the vehicle 'C' is not properly captured, the face removal controller 5 does not properly recognize the rear vehicle number of the vehicle 'C'. Accordingly, the face removal controller 5 may remove the entry image information and the key of the vehicle 'C'. The value 20, location information and speed information are stored in a temporary memory.

At this time, since the front vehicle number and the rear vehicle number are identically detected, the vehicle 'A' and 'B' transmit the same vehicle number to the lane controller 7 and the rear number of the vehicle 'C' Since they do not match, data including the image information stored in the temporary memory is created as a candidate list of the vehicle 'C' and transmitted to the image server 8.
