Highway pavement flatness rapid measurement system and method
The invention discloses a highway pavement flatness rapid measurement system and method. The system comprises a video machine vision module, a three-dimensional point cloud data processing module and a flatness index calculation module. The video machine vision module is connected with the three-dimensional point cloud data processing module; by arranging the video machine vision module, it is prevented that in the image processing process, cross contamination of an original image is caused, and the recognition accuracy is affected, after the human body and vehicle recognition unit ends, a corresponding window is closed immediately, a memory is released, and the robustness of all the units is guaranteed; the high density of data acquisition can be improved, the surface point cloud information of the target object can be obtained in a large-scale and high-density manner through single data acquisition, the information is not limited to a single point, and relatively precise surface form information can be obtained; and meanwhile, the point cloud data is preprocessed in three aspects of point cloud data denoising, point cloud data simplification and point cloud data registration, so that the accuracy of pavement flatness measurement can be further improved.
本发明公开了一种公路路面平整度快速测量系统及方法，包括视频机器视觉模块、三维点云数据处理模块与平整度指标计算模块；视频机器视觉模块与三维点云数据处理模块相连接；通过设置视频机器视觉模块，防止在图像处理过程中造成交叉污染原图像，影响识别的准确性，在人体与车辆识别单元结束后，立即关闭相应的窗口，并释放内存，保证各单元的健壮性；能够提高数据采集的高密度，通过单次数据采集可以大规模、高密度的获取目标对象的表面点云信息，而不局限于单个点，能够获得相对精密的表面形态信息；同时通过点云数据去噪、点云数据精简及点云数据配准三方面对点云数据进行预处理，从而能够进一步提高路面平整度测量的精准度。
