无人机航测技术在高速公路勘测及辅助选线中的应用

无人机低空航测弥补了传统大飞机航空摄影测量在影像分辨率、地物几何精度、飞行成本方面所存在问题,其在高速公路勘测与辅助选线中的应用,大大提升了勘测效率,增强选线的科学性。文章立足工程实际,对无人机航测技术的应用方式进行全方位探讨,以期为后续相关实践工作的开展提供理论参考。

UAV low altitude aerial survey makes up for the problems existing in traditional large aircraft aerial photogrammetry in image resolution,geometric accuracy of ground objects and flight cost.its application in highway survey and auxiliary route selection has greatly improved the survey efficiency and enhanced the scientific nature of line selection.Based on the engineering practice,this paper discusses the application of UAV aerial survey technology in an all-round way,in order to provide theoretical reference for the follow-up related practical work.
