General-purpose vehicle driving data recording system and processing method

Abstract

The invention discloses a general-purpose vehicle driving data recording system. The general-purpose vehicle driving data recording system comprises an instrument panel camera, a frontward view-angle camera, a vehicle-mounted sensor, a data processing module and a field recovery module, wherein the instrument panel camera is used for photographing instrument panel image information in a vehicle driving process in real time; the frontward view-angle camera is used for photographing frontward image information in the vehicle driving process in real time; the vehicle-mounted sensor is used for acquiring vehicle state information in the vehicle driving process in real time; an instrument panel database is loaded in the data processing module, and the data processing module is used for comparing with the instrument panel image information transmitted by the instrument panel camera; the data processing module is used for monitoring a vehicle state according to the instrument panel image information, the frontward image information and the vehicle state information; when the vehicle state is abnormal, the data processing module is used for carrying out collection processing and preserving the obtained information and outputting an alarming signal; the field recovery module is used for determining an accident occurrence key time point according to instrument panel real-time information data and the vehicle state information, which are transmitted by the data processing module when a vehicle is subjected to a traffic accident; an accident panoramic image is recovered by utilizing the frontward image information at the key time point.

Description

technical field [0001] The invention relates to the technical field of vehicle driving record and driving process restoration, in particular to a general-purpose vehicle driving data recording system and processing method. Background technique [0002] When special events, accidents or failures occur in the car, it is necessary to obtain driving data to record special events and analyze the causes of accidents or failures, but these driving data are difficult to obtain after the event. [0003] When the driver is driving, the main focus is on three aspects: the front view, the instrument panel, and the perception of the driving state of the vehicle (such as sound, vibration, etc.). In the existing system, few of these three aspects of information are aggregated and saved, and used for driving process restoration. Moreover, there are many indications on the instrument panel and they are not universal. Many drivers can only recognize commonly used indication data. They often ...

[0010] In addition, the GPS positioning system is commonly used in existing vehicles to locate and judge the driving status of the vehicle. However, due to the low positioning accuracy of GPS, there are stability problems in the GPS signal during the movement of the vehicle, which makes the continuity and reliability of the data not high enough.

Most of the existing schemes use electronic data as a reference, but electronic data cannot be used as intuitive evidence; due to the different types and models of vehicles, there is currently no simple general-purpose device that can accurately record the driving status of vehicles. In the event of an event or accident, complete evidence cannot be preserved, and the state of the vehicle at that time cannot be fully reproduced
