The Distant Outlier Filter detects points that are isolated from the main scene in all point clouds and recycles them.
The removed points are not used in further steps such as the terrain classification.

  • 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 Outliers

The Distant Outlier Filter automatically detected and removed 30 outliers from the dense point cloud. The message is shown in the status center.

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.
