Road waterlogging depth measurement method based on contour lines generated from point clouds

Abstract

A road waterlogging depth measurement method based on contour lines generated from point clouds includes the steps of: S1, acquiring road surface point cloud data using a laser scanner, and processing the acquired road surface point cloud data; S2, generating a relatively regular triangulation network using oracle transportation management (OTM) software based on the processed data, and constructing a digital elevation model (DEM); S3, drawing contour lines by integrating the DEM with Toggle Contours technology, and performing quality inspection and post-processing on the drawn contour lines; S4, performing projection transformation on a contour map; and S5, calculating a road waterlogging depth. According to the present disclosure, by adopting the above method, urban waterlogging risk management in urban management systems can be effectively addressed, and installation and maintenance costs can be saved.
