System for reversely reconstructing scene of vehicle accident

Abstract

The invention discloses a system for reversely reconstructing the scene of a vehicle accident. A trip computer data acquisition unit (1) is connected with a speed sensor, an accelerator / brake operation sensor and a steering wheel steering sensor and is connected with a central processing unit (CPU) data integrated unit (2) through a wireless technology; the CPU data integrated unit (2) is connected with a global positioning system (GPS) / compass navigation system and a camera, and is connected with a server (3) through a third-generation / fourth-generation (3G / 4G) network; the server (3) is connected with a display device. The system has the advantages that the accident is traced by strict time alignment of video information and trip track / trip operation information; the trip track can be traced by virtue of a GPS / compass positioning function; a trip path before and after the accident happens can be completely traced, so that labor and material resources for scene survey can be saved to a large extent.

Description

technical field [0001] The invention relates to the recording of accidents or abnormal situations, to a recorder, especially to a system for reversely reproducing the scene of an automobile accident. Background technique [0002] In the existing reverse reproduction process of traffic accidents, there are usually two options: [0003] First, the traffic police department and the insurance department determine the responsibility for the accident based on the scene of the accident, questioning the parties and witnesses, taking pictures of the scene and using some surveillance videos. In this process, a lot of manpower and material resources are required, and due to some human reasons, there may be some deviations in the restored scene. [0004] 2. At the same time, there is also the above-mentioned process combined with the driving recorder (car black box) program of the car driving computer, and the reverse process is carried out through the driving process data.

Problems solved by technology

[0005] Option 1 mainly relies on on-site surveys and evidence provided by bystanders. In some cases, due to the influence of factors such as the angle of the observer and on-site damage, the consistency of the reverse review is often biased, and it takes a lot of manpower and material resources. relatively large

[0006] The main problem of the second option is that there is no vehicle track and on-site image data, and it is difficult to reverse the process of some vehicles colliding with pedestrians or vehicles colliding with low-speed moving objects.
