Resample

|
This tool allows you to resample point clouds. It works on any set of grid point clouds or unstructured point clouds. |
On top of the dialog you are asked to input the subsampling factor s. A new point cloud will be created taking one point each s from the original cloud. If you are resampling grid point clouds, the resampling operation will take into account the structure of the grid. Therefore, the grid structure will be divided in cells with size square_root(s) by square_root(s), and one point will be taken for each cell. To clarify this, in the grid point cloud case the dialog shows you a message with the original and the resulting grid size, as in the figure above.
Optionally you can hyperlink the subsampled scans with the higher resolution ones. This allows you to work with a lot of data by doing operation on the light versions of the data.
