The invention discloses a road image recovery early warning system and method based on foggy environment perception, and belongs to the technical field of intelligent vehicle safety auxiliary driving.According to the method, a foggy day image classifier, a classifier with different foggy concentrations, a light foggy day image recovery model based on a DCP method and a dark foggy day road information recovery model based on SSR and DCP method fusion are constructed, and information recovery is realized by adopting an optimal method for different foggy day types in real time. In the driving process, road video images in the vehicle advancing process are collected, whether fog exists in the images or not is judged in real time, the image types are judged in real time according to differentfog concentrations, an optimal algorithm is adopted, real-time image information recovery is conducted, visual enhancement is conducted on the images in the foggy days, and the influence of low visibility in the foggy days on the vision of a driver is weakened. By using the driver attention distraction detection module, the early warning module and the road moving pedestrian detection module, theprobability that a driver drives to have a vicious traffic accident under the condition of low visibility in foggy days can be greatly reduced.

    基于雾天环境感知的道路图像恢复预警系统及方法属于智能车辆安全辅助驾驶技术领域。本发明构建了雾天图像分类器、不同雾浓度分类器、基于DCP方法的轻雾道路图像恢复模型、基于SSR与DCP方法融合的昏暗雾天道路信息恢复模型、实时针对不同雾天类型,采用最佳的方法实现信息恢复。在行车过程中,采集车辆行进过程中的道路视频图像,实时判断图像是否有雾、根据不同雾浓度,实时判断图像类型,采用最佳算法,实时图像信息恢复,实现对雾天图像进行视觉增强,减弱雾天能见度低对驾驶人视觉产生的影响。驾驶人注意力分散检测模块、预警模块和道路运动行人检测模块的使用能够大幅降低驾驶人在雾天低能见度条件下驾驶发生恶性交通事故的概率。
