Fast Ground Points Extraction Method in Electric Line Inspection Based on the Progressive Encryption TIN

    Abstract
  • Introduction Point cloud data can be gotten during the electric line inspection using the LiDAR technology. The point cloud should be classified if the point cloud need to be used in the advanced applications. And the ground points classification is a very important progress during the progress of the point cloud classification. And the ground points extraction method based on the progressive Encryption TIN can extract the ground points accurate but the efficient of the method is very low.
      Method  To the problem we proposed an imitation progressive encryption TIN method. The method based on the Progressive Encryption TIN method and assumed that the plane of nearest three points was more accurate the extract the ground compared with the triangulation plane. In this method the kd-tree was used to organization the point to improve the efficiency.
      Result  The purposed method improves the efficiency very much compared with the progressive encryption TIN method with the almost same accurate.
      Conclusion  And the purposed method can meet the requirement of the fast and large data process.
