Abstract
The data in vehicle laser scanning system were processed in blocks using the trajectory data due to the curbs along most roads in city.Part of the point cloud within each block were projected onto the profile.Then the curb points were extracted from the pseudo scan line which was acquired from the profile point cloud.Finally,the cubic spline interpolation method is used to interpolate the extracted road curb points to obtain the road boundary line.Experiments show that this method is feasible and effective.关键词
