Description
Technical Field
The invention relates to the technical field of image defogging processing, in particular to a visual enhancement defogging system for assisting in driving of a motor vehicle.
Background
The vision enhancement system for motor vehicle driving is an image processing system applied to road driving process. In haze weather, images of outdoor objects appearing in the field of vision of drivers often degrade due to turbid media (such as solid particles, mist, etc.) in the atmosphere, which is caused by the absorption or scattering of light by fog, mist, raindrops, etc. in the atmosphere. Image degradation varies spatially as the degree of atmospheric scattering is related to the distance of objects from the human eye. The light reflected by the object received by the human eye is attenuated. In addition, the light obtained by the eye is also mixed with atmospheric light (ambient light reflected by atmospheric molecules). Therefore, the forward view field acquired by the driver in the foggy weather is a degraded image, and the image contrast is degraded, resulting in color distortion. Meanwhile, raindrops can block target objects in the image, so that local areas become blurred.
Because the particles in the atmosphere cause serious interference to the vision definition of a driver, the judgment and the reflection speed of the driver are influenced, the transportation speed is reduced, and traffic accidents are frequent. Therefore, the method has important significance for the research of the definition of the driving visual field image of the driver in rainy and foggy days.
With the continuous development of computer software and hardware technology in recent years, it has become possible to perform sharpening processing on the scenery images of the shot images in rainy and foggy weather. The image rain and fog processing technology is widely applied to the fields related to video monitoring, terrain surveying, urban traffic and the like, and the problems of blushing, blurring, low contrast and the like caused by image shooting in rain and fog weather are solved. However, the algorithm is not beneficial to the driving process, and the technology can be combined with corresponding hardware equipment to provide a real-time clear picture for a driver.
Therefore, in view of the above situation, there is a strong need to develop a vision-enhanced defogging system for assisting the driving of a motor vehicle to overcome the shortcomings of the current practical application.
