 ===== Concepts ===== ===== Concepts =====
  
-The change between two pointclouds can be analyzed +The change between two point clouds can be analyzed by dividing the point cloud in voxels and counting the number of added and removed points within every voxel.
  
 +Point cloud change detection project files are stored in the same location as the source point cloud. 
  
  
 ===== Source ===== ===== Source =====
  
-Every pointcloud from the datasetlist can be selected in the source dropdown list. +Use the generic workflow for [[dev:desktop_ext:generic|]] to define the source file. 
  
-===== Parameters =====+The method for the range of interest is 'Area'. 
  
-==== Algorithm ==== 
  
-=== Voxel Size ===+===== Compare Point Cloud =====
  
-The selected area is divided in voxels. For every voxel, the change detection will be applied on how many points are added or removed. +Add the active point cloud dataset from the dataset list that will be compared with the source point cloud dataset.  
 +===== Parameters =====
  
-=== Voxels Change Pts Min ===  +Generic concepts, see [[dev:desktop:preferences:detectors|]] 
- +===== Results =====
-The minimum number of points that should be added or removed in a voxel voxel in order to add the voxel and the points to the result datasets.  +
