LiDAR360 Classification

Settings

  • Input Data: The input file can be a single point cloud data or a point cloud dataset, which must be opened in the LiDAR360 software.
  • From Class: Source class(es).
  • To Class: Target class.
  • Neighbor Points (default value is"10"): The number of neighbors that will be used to determine whether a point is a noise in the sky. Calculate the distance between each point to the nearest point and calculate the standard deviation of the nearest distances.
  • Multiples of std deviation (default value is"5"): If the deviation of points beyond the minimum allowable threshold, they are considered as noise in the sky. The larger the threshold, the less the noise will be divided into.
  • DefaultValue: Click this button to set all parameters as default.
