The invention discloses a recognition and risk early warning method for a bad sight distance road section in a highway reconstruction and extension construction period, and the method comprises the steps: collecting the road and environment information of a target road section, and obtaining the point cloud data of the target road section; performing voxelization processing on the point cloud data to obtain a processed point cloud; extracting observation points along the expressway from the point cloud, and calculating the driving sight distance of the observation points; judging whether the driving sight distance is smaller than the parking sight distance, and if yes, determining that the target road section is a risk road section; if not, the target road section is not the risk road section. According to the invention, the driving sight distance along the highway can be automatically evaluated, and the risk road section with insufficient sight distance can be accurately determined.
本发明公开了一种高速公路改扩建施工期不良视距路段识别与风险预警方法,包括:采集目标路段的道路与环境信息,获取目标路段的点云数据;对所述点云数据进行体素化处理,得到处理后的点云;从所述点云中提取高速公路沿线的观察点,计算观察点的行车视距;判断行车视距是否小于停车视距,若是,则目标路段为风险路段;若否,则目标路段不为风险路段。本发明能够自动评估高速公路沿线的行车视距,准确确定视距不足风险路段。
