Description

The invention relates to the field of traffic regulation, in particular to the identification of vehicles (hereinafter referred to as the vehicle). This method can also be used to identify the vehicle of citizens in order to comply with certain regimes (including the COVID 19 ¹ self-restriction regime ( ¹ Application related to compliance with the self-isolation regime, see page 4)).

At the moment, there are various systems for identifying vehicles by state numbers. For example, using a camera with license plate recognition (https://www.videomax-server.ru/support/articles/raspoznavanie-avtomobilnykh-nomerov-proektirovanie-nastroyka/).

There are also ways to identify and detect vehicles using an induction system. So according to the invention (RU 2 566 586, publ. 04.22.2013) in the induction system for the detection and identification of vehicles, containing electronic means of identification with electronic memory installed on vehicles, and a reader for reading and / or writing information from electronic means of identification in the HF frequency range, the electronic means of vehicle identification are made in the form of a resonator built into the vehicle registration plate, containing a multi-turn frame and a microchip connected to it, with a non-volatile memory that provides storage of vehicle identification data, including at least registration data number of the vehicle, so that the microchip is powered by an electric current induced by an external alternating magnetic field, the reader is equipped with a magnetic frame with a perimeter of 1/5 to 1/2 wavelength, installed in a dielectric housing under the surface of the roadway on the lower part of the road and ensuring the formation of an alternating magnetic field around it, constituting the zone of action of the magnetic frame, covering the entire width of the strip of the carriageway and having a length along the strip of the road up to 2 m, and a height of at least 1 m from the road surface, parcels generated by electronic identification means and the minimum vehicle identification time correspond to a vehicle speed of up to 250 km / h and are no more than 25 ms, the electronic identification means and the reader are designed to encode and decode data and restrict access to data.

Also known is the SYSTEM FOR RADIO FREQUENCY IDENTIFICATION OF THE USER OF THE VEHICLE (RU 2 241 243, publ. 27.11.2004). A system for radio frequency identification of a vehicle user, which includes a tag connected over the air to a reader containing a serially connected and interconnected transceiver radio module with an antenna, a signal processing unit and a microcontroller, to the outputs of which light and / or sound signaling units are connected - with this tag has a design identical to the reader, ensuring their interchangeability, while the tag and the reader are made with the possibility of conducting a dynamic identification dialogue with periodic transmission from the reader to the tag or from the tag and the reader of signal parcels with random numbers varying randomly from one message to another, by receiving the indicated signal transmissions, respectively, by a tag or reader, nonlinear transformation of the specified random numbers, re-emission of signal transmissions with nonlinearly transformed random numbers, identical nonlinear transformation of random numbers in the reader or tag that transmitted the specified signaling messages lks with random numbers, comparing identically nonlinearly converted and received nonlinearly converted random numbers and including, in case of mismatch of the indicated nonlinearly converted random numbers, light and / or sound signaling blocks to indicate the use of an unregulated tag by an intruder or when deleting a regulated user tag from the reader outside of radio communication zones.

The common disadvantages of all these solutions are the need for effective identification and detection of vehicles, the installation of additional expensive equipment in large quantities. Which is not always possible for economic reasons. Also, difficulty can be caused by the installation of such equipment in hard-to-reach places, for example, on country roads, forest roads.

The technical problem to be solved by the present invention is to eliminate these shortcomings: to create a vehicle detection and identification system without additional ground equipment.

The technical problem posed is solved by using an optical marker placed on the vehicle and an aircraft (hereinafter referred to as an aircraft) with equipment for identifying a vehicle using this marker.

Proposed as an invention, a method for identifying a vehicle using an aircraft (Fig. 1), where the positions indicate: LA - 1 with a video camera 11, TC 2, optical marker 21.

Any aircraft can be used as an aircraft - for example, a helicopter, an airplane, a satellite, a UAV (unmanned aerial vehicle), a balloon, etc.

With this method, the optical marker must be applied to a place where it can be visually fixed using technical means - for example, on the roof or hood of a vehicle.

When using a two-wheeled vehicle (for example, a motorcycle, scooter), it is advisable to apply an optical marker on the driver's helmet.

It is allowed to use a barcode (QR code) for marking. The fact is that many modern cameras are able to identify objects equipped with barcodes in automatic mode.

To increase the control distance of aircraft moving in poorly lit terrain and / or at night, it is recommended to make an optical marker using luminescent paint.

The proposed method of identification and detection by an aircraft is carried out as follows.

Let the task of the aircraft 1 reveal (identify) a vehicle moving from point "A" to point "B". An identifying marking is applied to the vehicle 2 by any known method, which will be the optical marker 21 for the aircraft.

It is preferable to apply the optical marker 21 to the roof of the vehicle 2. This embodiment is shown in FIG. one.

The aircraft takes off at point "01" and gains the altitude set initially in device 12 (control system - CS), which is part of the structure of the UAV 1, or transmitted to this device in any known way.

Ground material object 2 begins to move from point "A" to point "B". The video camera 11, located on the aircraft 1, monitors a certain optical marker 21. All optical markers (including those on other vehicles) recorded by the video camera 11 are checked against the given base using the control system - device 12. When a given optical marker 21 is detected, the control system The aircraft (device 12), depending on the specified algorithm, issues an event notification. FIG. 1 cone 13 symbolizes the field of view of the video camera 11.

Vehicle 2 can move on any rough terrain, and the only limitation is its passability. The possibility of the proposed method is limited by the movement of a ground material object in the tunnels, but this case is quite rare.

With certain preset algorithms, the aircraft can accompany the detected vehicle (the so-called “follow me” function). The "Follow me" mode is a UAV mode in which it constantly follows the operator at a distance - as if the car is "on an invisible leash". The role of such a leash can be played by a remote control that constantly gives a signal to orient the device, a smartphone with a GPS module informing the quadrocopter about the location of the user, etc. In any case, the "Follow those" mode provides some interesting features - for example, automatic video recording without the need to constantly guide the quadrocopter from the remote control (https://www.e-katalog.ru/list/943/pr-21538/). This function is one of the ways to control the UAV.

This method can be effectively applied, for example, by law enforcement agencies that ensure road safety, as well as, for example, by transport companies to detect and escort their cargo (transported, including by means of railway transport).

Also, the method can also be used to identify the vehicle of citizens in order to comply with certain regimes (including the COVID 19 self-limitation regime). For example, issued passes allowing a certain person to move around the city (including on certain days) can be applied, for example, to the roof of the vehicle. The aircraft will be able to quickly and efficiently identify:

1) Vehicle without gaps;

2) Invalid, expired passes, etc.

The technical result of the application of the proposed system will be to increase the safety of the population by eliminating the shortcomings of existing similar identification and vehicle detection systems.
