摘要
随着遥感技术的不断发展,利用当今流行的无人机,可以方便快捷地采集地表信息。无人机低空遥感技术应用在道路安全方面具有一定的现实意义,它可以为广大车主提供安全警示,为道路监管部门提供辅助决策。通过对道路影像的采集、处理、计算和分析,找出存在安全隐患的路面障碍物,识别路坑,通过数字测图系统,计算路坑的半径大小和深度,根据不同的车速预判事故风险,为道路安全监测提供科学依据;同时,为已破坏的道路提供修复方案,估算修复所需材料数量,做到有的放矢,节约资源,提高效率。实验结果证明,通过无人机低空遥感技术,既可以为行车安全提供科学预判信息,又可以为道路修复提供相对准确的所需材料用量。
With the continuous development of remote sensing technology,the surface information can be collected conveniently and quickly by using the popular UAV.The application of UAV low altitude remote sensing technology in road safety has certain practical significance.It can provide safety warning for most driver,and provide auxiliary decision-making for the road supervision department.Through the collection,processing,calculation and analysis of the road image,the UAV can find out the road obstacles with potential safety hazards,identify the road pit,calculate the radius and depth of the road pit through the digital mapping system,predict the accident risk according to different speed and provide scientific basis for the road safety monitoring.At the same time,UAV can provide repair scheme for damaged roads,estimate the quantity of materials needed for repair,and achieve the target of resource saving and efficiency improvement.The experimental results show that the UAV low altitude remote sensing technology can not only provide scientific prediction information for driving safety,but also provide relatively accurate material consumption for road repair.
