摘要
The present invention relates to a method of extracting linear design elements of urban roads using digital maps and LiDAR data, and to a computer-readable recording medium recording the program. The road design element is obtained as the linear information of the road that can determine various safety factors according to the driving speed of the road.For this, the road centerline of the 1 / 1,000 numerical map and the altitude information of LiDAR are used to It provides an algorithm that extracts the exact 3D coordinates and automatically extracts the linear design elements of the actual road from the location information of the extracted road center line.;In addition, the linear design element automatic extraction algorithm provided in the present invention is implemented in a GUI environment program to obtain linear design element information on a road in an actual target area, and the three-dimensional modeling and linear analysis processes of the road are performed from these information. To perform.;Road linear design elements, telematics, driver assistance systems, 3D modeling, digital maps, LiDAR
