Abstract

An integrated control system and method using a vehicle surveillance camera, the method including: receiving vehicle license plate number information obtained by analyzing an image captured using the vehicle surveillance camera, from the vehicle surveillance camera via a server; receiving time information and position information about when and where the captured image was generated, from the vehicle surveillance camera via the server; and constructing a database by referring to the vehicle license plate number information, the time information, and the position information received via the server.

Claims

1. An integrated control method using a vehicle surveillance camera, the method comprising:

receiving, by a server, first license plate number information of a plurality of first nearby vehicles, in a moving traffic, obtained by analyzing a first single image captured by a first vehicle surveillance camera provided in a first image capturing vehicle, wherein the plurality of first nearby vehicles comprises;

a first front left vehicle located on a front left side of the first image capturing vehicle;

a first front vehicle in front of the first image capturing vehicle; and

a first front right vehicle located on a front right side of the first image capturing vehicle;

receiving, by the server, first time information about a first point in time when the first single image is captured by the first vehicle surveillance camera, a first position of the first image capturing vehicle at the first point in time when the first single image is captured and a first speed of the first image capturing vehicle at the first point in time when the first single image is captured;

receiving, by the server, second license plate number information of a plurality of second nearby vehicles, in the moving traffic, obtained by analyzing a second single image captured by a second vehicle surveillance camera provided in a second image capturing vehicle, wherein the plurality of second nearby vehicles comprises;

a second front left vehicle located on a front left side of the second image capturing vehicle;

a second front vehicle in front of the first image capturing vehicle; and

a second front right vehicle located on a front right side of the second image capturing vehicle;

receiving, by the server, second time information about a second point in time when the second single image is captured by the second vehicle surveillance camera, a second position of the second image capturing vehicle at the second time when the second single image is captured and a speed of the second image capturing vehicle at the second point in time when the second single image is captured; and

constructing a database comprising a first row of data and a second row of data, wherein;

the first row of data includes the first license plate number information of the first front left vehicle, the first front vehicle and the first front right vehicle, the first time information, the first position and the first speed of the first image capturing vehicle, received by the server, and

the second row of data includes the second license plate number information of the second front left vehicle, the second front vehicle and the second front right vehicle, the second time information, the second position and the second speed of the second image capturing vehicle, received by the server.

2. The method of claim 1, wherein the first and the second license plate number information of the plurality of the first and the second nearby vehicles, and the first and the second time information and the first and the second positions of the first and the second image capturing vehicles are converted into metadata.

3. The method of claim 1, wherein the first and second license plate number information of the plurality of the first and the second nearby vehicles, and the first and the second time information and the first and the second position information of the first and the second image capturing vehicles are data that are obtained by analyzing the first and the second single images captured by the first and the second vehicle surveillance cameras for a frame of a video image captured and structuring the analyzed data.

4. The method of claim 1, wherein each vehicle surveillance camera is installed on a front side or a lateral side of a vehicle.

5. The method of claim 1, wherein the vehicle license plate number information of the plurality of the first and the second nearby vehicles, the first and the second time information and the first and the second position information of the first and the second image capturing vehicles received by the server are coded data.

6. The method of claim 1, further comprising:

receiving a request to search for a vehicle at a predetermined position and a predetermined time, via the server;

extracting data that corresponds to the search request, from the database, via the server; and

extracting a vehicle number from the extracted data, via the server.

7. The method of claim 1, further comprising:

receiving a request to search for a predetermined vehicle from a user terminal;

extracting any data including the vehicle license plate number information of the predetermined vehicle from the database, via the server,

listing the time information corresponding to the extracted data according to time;

obtaining a movement path of the predetermined vehicle by using the position information corresponding to the listed data.

8. The method of claim 1, further comprising, when the server is to search for a time period required to pass a section between a first position and a second position, wherein the first position is a start position and the second position is an arrival position:

extracting the vehicle license plate number information including both information regarding the first position and information regarding the second position from the database, via the server;

calculating time required for a vehicle having the extracted vehicle license plate number information to pass the section by using time information corresponding to the information regarding the first position and the information regarding the second position, via the server; and

calculating an average of the time required for the vehicle having the extracted vehicle license plate number information to pass the section.
