The invention discloses a risk road section prediction method and system, computer equipment and a storage medium, and relates to the technical field of road safety, and the method comprises the steps: obtaining the street view image data of a road section with a traffic accident and without an accident, inputting the street view image data of the road section with the traffic accident and without the accident into a semantic segmentation model, outputting the predicted segmented image, and obtaining pixel proportions of different environmental elements of the road according to the segmented image; meanwhile, a risk road section prediction model is constructed based on an XGBOOST algorithm; inputting the pixel proportions of the different environmental elements into the risk road section prediction model, and outputting the prediction probability of an accident of each street scene image; by deeply analyzing the pixel proportions of various objects in the visual environment of the driver, the accuracy and stability of XGBOOST prediction are enhanced, the risk of the local transportation line is accurately evaluated, the environmental elements of the local transportation line are analyzed, and the method has a wide application prospect.
本发明公开一种风险路段预测方法、系统、计算机设备及存储介质,涉及道路安全技术领域,该方法包括:获取发生交通事故以及无事故路段的街景图像数据,将交通事故以及无事故路段的街景图像数据输入语义分割模型中,输出预测的分割图像,根据分割的图像获得道路不同环境要素的像素比例;同时基于XGBOOST算法构建风险路段预测模型;将不同环境要素的像素比例输入风险路段预测模型中,输出每张街景图像发生事故的预测概率;通过深入分析驾驶员视觉环境中的各类物体像素占比,增强了XGBOOST预测的准确性和稳定性,对当地运输线路的风险进行准确评估并分析其环境要素,具有广泛的应用前景。
