摘　　要：以某沥青公路路面为例,探究了地面三维激光扫描技术在其平整度检测中的应用。地面三维激光扫描仪选择RIEGL VZ-1000,点云数据处理软件选择与其配套的RISCAN PRO,在设站扫描获取路面激光点云的基础上,对其进行了去噪、配准和随机采样等相关处理,有效提高点云质量。通过地面滤波进一步缩减点云数据数量,使用拟合算法提取道路边界线,确定路面范围后计算平整度。结果显示,该路段的国际平整度指数IRI基本在5 m/km以下,其中有2处IRI值存在异常增大是由于设置了减速带导致,由此可见该路段路面的行驶质量较好。Taking a certain asphalt highway as an example,this paper explores the application of ground 3D laser scanning technology in road surface smoothness detection.We selected the RIEGL VZ-1000 ground 3D laser scanner and the accompanying PISCAN PRO point cloud data processing software to perform denoising,registration,random sampling,and other processing on the point cloud data after scanning the highway point cloud data at the station,which effectively improves the quality of the point cloud data.Further reduce the number of point cloud data through ground filtering,extract road boundary lines using fitting algorithms,and calculate the smoothness after determining the road surface range.The results indicate that the international roughness index(IRI)of this section is generally below 5m/km,and the abnormal increase of IRI values in two places is due to the setting of speed bump,which shows that the road surface quality of this section is relatively good.
