Abstract

The invention discloses a method and a system for identifying road visibility based on an automobile data recorder, belonging to the field of automobile safety technology. According to the invention, the method comprises the following steps: when an automobile runs on the road, identifying a reference object as a preset target reference object by the automobile data recorder, acquiring the time for judging the reference object as a target reference object and the time that the target reference object disappears, and acquiring the automobile average running speed of the target reference object in the time on the automobile data recorder, thus calculating the visual range of the current automobile running road. The system enables the automobile data recorder to increase a new function of identifying road condition visibility, thus improving the function and application of the automobile data recorder, improving the warning and judgment capability of a driver on road running safety, and being greatly convenient for an automobile driver.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a method and system for identifying road visibility based on an automobile driving recorder. Background technique [0002] With the improvement of people's living standards, the demand for cars continues to increase, and the number of existing cars continues to increase. As a result, car drivers have an increasing demand for advanced safety assistance driving systems. As an instrument for recording relevant information such as images and sounds on the way of driving, the driving recorder has been relatively perfect in providing evidence for traffic accidents and as a driving monitoring technology. [0003] At present, in the field of automobile road safety, it is the future development trend to identify, warn and share the road conditions in front of the vehicle through various technical means. The visibility (visibility) status of the road ahead of the vehicle is reco...
