초록
The 3D Hough transformation is the one of the most powerful and popular algorithm for extracting planeparameters from LiDAR data. However, there are some problems when extracting building roof plane using3D Hough transformation. This paper explains possible problems and solution for extracting roof plane. Thealgorithm defines peak plane, exact plane, and LESS plane for extracting accurate plane parameters in theaccumulator of the 3D Hough transformation. The peak plane is the plane which is represented by peak inthe accumulator. The exact plane is the plane which is represented by the accumulator cell which is closestto the actual plane. The LESS plane can be calculated from all LiDAR points in the exact plane by usingleast-square adjustment. Test results show that proposed algorithm can extracts building roof plane veryaccurately.
