Description

The utility model relates to a control and measuring technique, namely, to a vehicle flow monitoring device with the function of automatically identifying their category by purpose, and can be used in the form of a stationary or automobile device located in the immediate vicinity of the highway to carry out advanced monitoring of traffic flow crossing the controlled area.

A well-known automated control system for the flow of vehicles on the roads during their movement, designed to automatically identify vehicles and develop an algorithm of actions in relation to their further operation (RU 2265889 C1, G08G 1/017, B60R 25/00). This system contains requesting devices located in the direction of travel of the vehicles, an electronic device mounted on the vehicle and configured to store the vehicle identification number, receive a signal from the requesting device, and transmit a response signal to the requesting device.

A well-known automated accounting system for vehicles (TC) and vehicle traffic control (RU 2185663 C1, G08G 1/017, B60R 25/00, B60R 13/10). The system includes a personal computer connected to the vehicle data storage server (TS), characterized in that it contains at least three electronic tags (EMs) installed on the vehicle, and a manual or stationary reader connected to the PC information entered in the EM, while in the EM located in the places of attaching the state number, information is entered on the vehicle brand, color of the vehicle, engine power, passport number on the vehicle, certificate of registration of the vehicle and state vehicle number, on travel time Last maintenance, in the EM located on the windshield, information is entered about the vehicle brand, vehicle identification number, information about the owner, information about the goods transported, departure and destination points, vehicle state number, vehicle passport number, service station number ( STO), in the EM located in the engine compartment of the engine compartment or directly on the engine, information is entered on the engine, chassis, body, engine power, vehicle year of manufacture.

A common drawback of these systems is the need to use special means such as RFID tags or databases containing information about registered vehicles to determine additional vehicle parameters. Thus, these systems do not allow to determine the category of the vehicle for its intended purpose at the time it crosses the controlled area in a fully autonomous mode of operation (if the vehicle is not equipped with a radio tag or there is no record in the database about it).

There is also a method of identifying vehicles (RU 2374693, IPC: G08G 1/017), which determines the presence of a vehicle by measuring the distance from at least one known point in space to the surface, and when the measured distance becomes less than critical, consider the presence of a vehicle defined, measure the distance from at least one known point in space to the surface points of the vehicle at least at one known point in time relative to the moment about definiteness presence of the vehicle, if necessary determine the speed of the vehicle using the received information determined by the geometrical parameters of the vehicle, and decide on its type.

The specified method is based only on the assessment of the dimensions of the vehicle and is not sufficiently informative in determining the category of the vehicle for its intended purpose.

The claimed utility model is aimed at eliminating the above disadvantages.

The technical result of the utility model is to expand the capabilities of automated monitoring and control of vehicles, in particular, determining the category of a vehicle according to its functional purpose by analyzing additional visual elements at the time the vehicle crosses a controlled area without using special databases and feedback tools.

The above technical result is ensured by the fact that the proposed device for monitoring the flow of vehicles with the function of automatically identifying their category by purpose includes at least one video camera configured to photo and / or video capture the image of the state registration plate of the controlled vehicle, as well as the image of the vehicle itself means, and an information processing unit including a module that is responsible for identifying the state reg the sign of the fixed vehicle, while the information processing unit additionally contains a module that is responsible for identifying and analyzing an additional visual element in the image of the vehicle, and a module that is responsible for assigning a certain category to the vehicle according to its functional purpose based on the analysis of the additional visual element.

The preferred field of application of the claimed device is the automatic determination of the category and identification of the GRZ TS at stationary and mobile control lines on highways.

The device can be configured to transmit to a remote server a packet of information about fixed vehicles, their identified state registration cards, their categories, etc.

Information on fixed vehicles can be previously placed in the data storage unit.

Figure 1 shows an exemplary diagram of the claimed device for monitoring the flow of vehicles with the function of automatically identifying their categories for the purpose.

1 - video camera, responsible for identifying and fixing the image of the vehicle in the field of view.

2 - information processing unit, which contains several modules:

- Module identification GRZ fixed vehicle

- Module for identifying and analyzing an additional visual element

- Module for assigning a vehicle category by functional purpose

The following is a description of the operation of the device.

A device for monitoring the flow of vehicles with the function of automatically identifying their category by purpose works as follows.

In a stationary embodiment, the video camera 1 is mounted on a roadside structure. In the mobile embodiment, the camcorder 1 is located in a patrol car. The camcorder is placed in such a way that vehicles with visible GRD pass through its field of view (the method of installing the camcorder is similar to most photo / video recording systems).

The video camera in the process of operation continuously at a certain interval forms photo frames with the image of the field of view, and transmits them to the information processing unit.

In the information processing unit, the frames from the video camera are sent to the identification module. If a GRD image is detected in the frame, it is identified (optical recognition of the alphanumeric sequence), after which the frames with the image of this vehicle are transmitted to the detection and analysis module of the additional visual element. In this module, the image of the vehicle is analyzed and typical visual elements typical for a certain category of vehicles are revealed on it. For example, for cars in a city taxi fleet, the characteristic visual elements are a special roof structure with the inscription and the “taxi” icon, a special inscription on the hood, two white stripes on the hood for the fire engine, red stripes, a red cross and vertical crosses for the ambulance digits "03".

The identified data is transferred to the module for assigning a vehicle category according to its functional purpose. In this module, the category that all the identified elements correspond to is determined by the identified visual elements. At the end, a data packet is generated for a specific vehicle containing the following information:

- photo of the vehicle with a visible GRD

- time and place of fixing the vehicle

- recognized grez

- category TC

Further, this information can either be stored in the data storage unit, or transmitted to a remote server for subsequent processing (making decisions on this TS).

Video camera 1 for fixing the image of the vehicle and identification of the state registration plate of the fixed vehicle can be implemented in the form of a black and white video camera. Designed to form frames with the image of the state registration plate (GRZ) of a vehicle (TS) for subsequent recognition. A black and white camera is preferably used, as according to its characteristics (sensitivity, speed, etc.) it is better suited for recognition of gas distribution devices than color.

The data processing unit 2 is intended for processing frames formed by the video camera and used in the process of the device. It can be implemented in the form of software modules (at the logical level), as well as in the form of a computer (at the physical level).
