The Distant Outlier Filter detects isolated points in all point clouds and recycles them.

 
Access:
  • Click Process Pix4Dsurvey process icon or,
  • On the Menu bar, click Process > Distant outlier filter.
 
Tip: It is recommended to run the Distant Outlier Filter before generating other results. For example, outliers in the point cloud can greatly influence the Terrain Filter process. Removing outliers will improve results.

Pix4Dsurvey distant outlier filter detects points

The Distant Outlier Filters check for points that are far away from the scene. For example, the filter automatically detected and removed 16 outliers from the dense point cloud. Removed points are not used in further steps such as terrain classification.

 
Note: The Distant Outlier Filter focuses on finding points that are isolated and far away from the point cloud. It therefore cannot be used to filter out noise in the main body of the point cloud.
