Break lines detection using 3D point cloud data is used in various fields such as shape recognition of structures, CAD data creation, downsampling, and plane (TIN) generation. In the previous research to detect break lines, a method using plane intersection lines of point cloud data, a method using normal vectors, and a method to find and connect cross-sectional change points for each cross-sectional view have been proposed. However, there are problems such as the inability to detect accurate break lines due to the noise of vegetation and trees included in the 3D point cloud data, and the limitation of target structures. Therefore, in this research, we propose a method for detecting break lines of structures that is superior to previous research by using the characteristics of the RANSAC.
