Abstract

<P>PROBLEM TO BE SOLVED: To realize a necessary quantity of recording with a constant connection video camera 3 as necessary by a computer 7. <P>SOLUTION: It is recognized that an accident has occurred according to a recording start signal (vibration, sound, and the movement of a person) decided based on a program in a non-volatile storage device mounted on a computer 7, and then the accident is recorded by the video camera 3 set at an intersection. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention records an accident at an intersection at an on-time recording by using image analysis, vibration analysis, sound analysis and the like.

[0002]

2. Description of the Related Art The conventional method of solving an accident is to check the situation of the parties after the accident, and the police check the situation, and there has been a conflict of opinion between the concerned vehicle (4) (driver). . This sometimes made it impossible to confirm the facts. In addition, it was a big fact that the technology for confirming facts relied on the experience of police officers. There were also times when we had to look for witnesses to resolve them.

[0003]

When an accident occurs at an intersection, the permanent video camera (3) can record the accident with a good chance so that the fact can be surely grasped. Thereby, the facts can be accurately grasped.

[0004]

The image recorded by the video camera (3) is always loaded into the memory of the computer (7). Here, the computer (7) recognizes that an accident or the like has occurred, and starts recording by a program start signal (vibration, sound (6), movement of person (5), etc.) of an opportunity. (At this time, the computer (7) is also recording the image before the recording start signal.) Here, the backward recording is stored in the memory of the computer (7) for the time set from the recording start signal. After this, police officers and others will not stop unless the machine is artificially stopped. This makes it possible to understand at a glance what the parties are doing immediately after the accident from the state immediately before the accident. Also, it is possible to understand the response of the parties until the arrival of the police officer. Normally, recording is always done and erased by the program of the computer (7).
Therefore, since the recording before the recording start signal is also performed, the time is traced back as needed from the point where the signal is input and the recording start signal is set, so that the time can be traced back to before the occurrence of the incident. As a result, the state of the traffic light at the time of the accident, the intrusion route of the vehicle (4), the person (5), etc. can be understood. For the recording part before that, the part before the recording start set time is automatically deleted and the memory is always secured. In addition, the external memory connected to the computer (7) in this case uses an external non-volatile storage device, and by making it easy to remove, it can be submitted to the police etc. like the conventional video tape. While maintaining flexibility. Furthermore, since it can be automatically transmitted to the police, insurance companies, necessary institutions, etc. on-time using the Internet, etc., the police side can see the video with accurate time regardless of whether it is active or passive. There is a high possibility that an accident can be resolved early even by pulling away. Also, regarding problem solving, a limited number of people plus a large number of specializations can be confirmed at the relevant organizations, which leads to even faster problem solving.

[0005]

[Effects of the Invention] The time taken to deal with accidents in the police can be greatly shortened because there is no need to talk around the cars (4) (persons) concerned. Since it is possible to respond immediately, the time required to relieve the victim will be dramatically reduced. It is possible to immediately deal with tracking such as hitting and hitting escape by analysis. Analysis is very easy because of digital recording. Furthermore, by using the Internet, it is possible to carry out analysis and analysis simultaneously at the accident site, in the police station, etc. In addition, it is possible to prevent falsification of documents when preparing documents with the police records.
