[0039] The purpose of the present invention proposes a simple model algorithm, which only detects the low visibility range less than 300m, and proposes a concept of visibility specially suitable for expressways. This model mainly focuses on the scene seen by the driver and reflects the real human eyes Visible distance. Finally, an economical detection method is tailored for expressway visual distance detection, and real-time detection and early warning are realized.
[0040] Basic principle train of thought of the present invention is:
[0041] The direct impact of low visibility on drivers is insufficient viewing distance. The smaller the viewing distance, the smaller the distance of the farthest object that the human eye can see, and the fewer the number of objects in the ordinary image. Then as the viewing distance decreases, the amount of continuous scenes will decrease regularly. Therefore, the reduction of the visible distance can be inversely deduced by quantifying th...
