The invention provides a pavement agglomerate fog detection early warning method and system, a storage medium and a terminal, which are applied to roadside equipment, and the method comprises the following steps: obtaining image data and environment data of a target road section; obtaining a visibility estimation value of the target road section based on a visibility estimation model and the image data; obtaining an agglomerate fog prediction result of the target road section based on an agglomerate fog prediction model, the environmental data and the visibility estimation value; and generating agglomerate fog early warning information based on the visibility estimation value and the agglomerate fog prediction result. According to the method, the agglomerate fog is predicted by considering the mobility of the agglomerate fog, the correlation between the agglomerate fog and environmental data and the historical change rule of the agglomerate fog, the vehicle is warned in advance under the condition that the agglomerate fog does not occur or arrives, and more sufficient response time is provided for the vehicle; a convolutional neural network-recurrent neural network model is adopted to simulate visual characteristics of human eyes, and visibility estimation precision is improved; the method has the advantages of high precision, strong availability, wide coverage and the like.
本发明提供一种路面团雾检测预警方法、系统、存储介质及终端,应用于路侧设备,其包括:获取目标路段的图像数据和环境数据;基于能见度估计模型和所述图像数据获得目标路段的能见度估计值;基于团雾预测模型及所述环境数据和能见度估计值获得目标路段的团雾预测结果;基于所述能见度估计值和所述团雾预测结果生成团雾预警信息。本发明考虑到团雾的可移动性、团雾与环境数据的相关性,及其历史变化规律对团雾进行预测,在团雾尚未发生或到达的情况下对车辆进行提前预警,为车辆提供更充分的应对时间;采用卷积神经网络‑循环神经网络模型模拟人眼的视觉特性,提升能见度估计精度;具有精度高、可用性强、覆盖面广等优势。
