摘　　要：目前,我国道路路面平整度的测量普遍采用人工检测方法,存在耗时、费力及危险性高的问题,且缺乏道路施工过程中实时测量路面平整度的手段。为解决这一难题,提出一种基于线激光的路面平整度过程检测方法。通过自主搭建的线激光系统实现高精度三维测量,测量误差可达到毫米级精度。采用小波变换算法优化了由于设备在作业过程中振动导致检测结果存在偏差的问题。对比实验结果表明,所提方法与激光断面仪在相同路段的平整度检测结果相似度达到85%以上,欧氏距离为2左右。基于线激光的路面平整度检测方法能够获取道路路面的三维形貌,从而准确计算道路路面的多维度特征,提升道路建设效率、降低成本损耗、完善道路检测能力,为我国道路建设施工提供全面、准确、多维度的路面平整度检测方法。Currently,road surface smoothness in China is typically measured using manual detection methods,which are time-consuming,labor intensive,and risky.In addition,these methods do not provide real-time measurements during road construction.To address these issues,we propose a road surface smoothness detection method based on line lasers.This method uses a custom-built line-laser system to achieve high-precision three-dimensional(3D)measurements with millimeter-level accuracy.The issue of deviations in the detection results caused by equipment vibrations during operation is optimized using a wavelet transform algorithm.The comparative experimental results show that the proposed method has over 85%similarity with the flatness detection results obtained from a laser section analyzer on the same road section,with a Euclidean distance of approximately 2.This line-laser-based method can capture the 3D morphology of a road surface,reduce cost losses,and enhance the detection capabilities of roads.The proposed method also provides a comprehensive,accurate,and multidimensional approach to road surface flatness detection for road construction in China.
