摘　　要：针对现有方法无法高标准完成公路信息测量的问题,以全州至容县公路项目为背景,利用无人机搭载激光雷达传感器进行数据采集,经点云去噪处理后,采用逐步滤波算法提取信息点,由道路三维重构来进行公路信息测量。结果表明,相较于传统方法,研究所提方法在高程误差控制方面具有明显优势,路段1和路段2的平均高程误差分别为0.009 m和0.008 m。由此可知,研究所提方法不仅提升了测量精度和效率,还为该领域的技术发展提供了理论支持。Aiming at the problem that existing methods cannot complete highway information measurement in a high standard,this paper takes the highway project from Quanzhou to Rong County as the background,uses a UAV equipped with a Lidar sensor for data acquisition,and adopts a step by step filtering algorithm to extract information points after point cloud denoising processing,and carries out highway information measurement by road three-dimensional reconstruction.The results show that compared with the traditional method,the proposed method has obvious advantages in elevation error control,and the average elevation error of section 1 and section 2 is 0.009 m and 0.008 m,respectively.It can be seen that the proposed method not only improves the measurement accuracy and efficiency,but also provides theoretical support for the technical development in this field.
