摘要
针对当前公路路面测量评定方法结构复杂、成本高昂的问题,构建了基于便携式三维激光扫描仪的测量评定方法。采用三维激光扫描仪对沥青公路路面数据进行测量,获取路面三维点云数据,经分析处理得到路面的三维高程曲面,使用RegularizeData3D算法和经验模态分解等方法对数据进行预处理,重构区域路面不平度,获取路面相应等级的路面平整度数据序列,最后求解和分析试验路面功率谱密度,并根据统计结果对整个试验路面状况进行评价。结果表明:系统能较好地重建所测区域路面的特征信息,路面平整度大部分集中在A级和B级,整体路面平整度在B级以上。
In order to solve the problem of complex structures and high costs of the current highway pavement measurement and evaluation methods,a measurement and evaluation method based on a portable 3D laser scanner was constructed.The 3D laser scanner was adopted to measure asphalt highway pavement data and acquire 3D point cloud data of the pavement.The 3D elevation surface of the pavement was obtained after analysis and processing,and the RegularizeData3D algorithm,empirical modal decomposition(EMD),and other methods were utilized to preprocess the data,reconstruct the regional pavement unevenness,and obtain the leveling data series of the corresponding pavement.Finally,the power spectrum density of the experimental pavement was calculated and analyzed,and the entire experimental pavement condition was evaluated based on the statistical results.The experimental results show that the system can better reconstruct the characteristic information of the measured regional pavement.The pavement leveling is mostly concentrated in grades A and B,and the overall pavement leveling is above B grade.
