Abstract EN
Dark channel prior (DCP) has advantages in image enhancement and image haze removal and is explored to detect highway visibility according to the physical relationship between transmittance and extinction coefficient.
However, there are three major error sources in calculating transmittance.
The first is that sky regions do not satisfy the assumptions of DCP algorithm.
So the optimization algorithms combined with region growing and coefficient correction method are proposed.
When extracting atmospheric brightness, different values lead to the second error.
Therefore, according to different visibility conditions, a multimode classification method is designed.
Image blocky effect causes the third error.
Then guided image filtering is introduced to obtain accurate transmittance of each pixel of image.
Next, according to the definition meteorological optical visual range and the relationship between transmittance and extinction coefficient of Lambert-Beer’s Law, accurate visibility value can be calculated.
A comparative experimental system including visibility detector and video camera was set up to verify the accuracy of these optimization algorithms.
Finally, a large number of highway section videos were selected to test the validity of DCP method in different models.
The results indicate that these detection visibility methods are feasible and reliable for the smooth operation of highways.
