Is set in advance in the image transmission server 25 to generate image information obtained by combining (Mix or Mux) the image information generated by the image camera 20 and the current setting information. In addition, in order to achieve the above-mentioned object in the process of distinguishing the assailant and the victim by the color of the traffic light when the traffic accident occurs in the intersection among the installation purposes, the image camera 20 is used to photograph the inside and the surroundings of the intersection. At least one of the traffic lights (10-12) are photographed and the color information (red, yellow, green) of the traffic light and the color position information of the traffic light from the image obtained by the video camera 20 automatically recognizes the signal controller ( 10) and the composition of the traffic accident perpetrator or victim identification system and method in the intersection characterized in that it consists only of the video camera 20 and the image transmission server 25 even in an environment that is not connected due to a communication function or communication problems and It's about action.

As described above, the role of the signal controller 10 and the image camera 20 has only an effect of detecting a signal violation or a speeding vehicle since it is an intermittent centered system such as a speed violation detection system and a signal remote control system. . In addition, a sound-oriented system similar to the present invention has been developed. In other words, it is considered as an accident when there is more than a certain noise in detecting an accident by using sound.In the course of everyday traffic accidents, the noise of the vehicle and other ambient sounds are generated, resulting in loud noise comparable to the traffic accident. There are many cases when there is a large sound accident while the sound is quiet at the same time. In order to overcome these problems, image-oriented invention devices have emerged, but this also reveals many problems. Therefore, the detector is sometimes used to solve the above problems, but the detection capability is significantly lower than the installation and operating costs. However, the effect of the present invention not only solves the problems shown in the above device, but also provides real-time information on traffic accidents occurring in intersections that are instantaneously and comprehensively that systems installed for the purpose of signal violations or speed violations cannot be solved. In addition to providing a clear and accurate screening of perpetrators and victims. That is, the video information and the present information are synthesized (mixed or muxed) in the video transmission server 25 and stored, or the DVR server 25-16 using the means of the server 25 and the communication means (network: 70). Or, if a traffic accident occurs in the area where the system of the present invention, which is stored and stored in the database 40 of the data storage device 30-4 in the central management server 30, is applied, And in an environment where it is impossible to determine the authenticity of the damaged vehicle and it is difficult to automatically detect a traffic accident, the system can reliably prove the authenticity of the vehicle and can automatically detect and inform the traffic accident. . In addition, it not only detects the accident scene so that rescue workers can be promptly put into the scene when a traffic accident occurs, but also scientifically proves the problem that the voice of a person is advantageous in proving the mistake of the above traffic accident. Demonstrating mutual recognition of the parties from an objective standpoint not only has the effect of making conclusions easier to draw, but also the apparent authenticity of traffic accidents between the perpetrator and the victim due to the problem of the perpetrator and the victim being reversed during the traffic accident process. The effect of resolving economic and psychological sequelae and the information on hit-and-run vehicles can be secured, thereby resolving the injustice that victims suffer from double damage. In addition, as the present invention is installed and operated, there is also a traffic accident prevention effect can be obtained a multi-purpose effect that can reduce the physical and mental damage caused by the accident. In particular, in the event of a fatal accident in a traffic accident, it is possible to quickly dismiss accident victims on site who can die with the help of rescue personnel quickly and confidently, thus reducing valuable casualties and saying that the dead are victims. In this case, there is an effect that can easily be solved to serious problems that can be changed to the perpetrator and often encounter the unjust events.
