Filtering Your Point Cloud

You can filter your point cloud by adjusting the number and quality of points it includes. NukeX filters the tracked point cloud directly, without recalculating, streamlining your workflow.

1.   Ensure that Display rejected points is enabled and adjust the threshold controls to update the 3D Viewer dynamically. Rejected tracks are highlighted in red.
2.   Adjust the Angle Threshold to set the minimum acceptable angle to triangulate 3D points (in degrees). Points with a large triangulation angle tend to be more accurate.

Set a threshold of 0 to triangulate all points or increase the threshold to highlight the least accurate points.

TIP:  As a rule of thumb, anything below 5 degrees is likely to be incorrect.

3.   Adjust the Density Threshold to set the minimum acceptable point density. Isolated points tend to be less accurate.

Set a threshold of 0 to output all points or increase the threshold to highlight the most isolated, less accurate points.

4.   The Viewer wipe tool can help you locate isolated points by comparing the 2D source footage to the point cloud.

Set Input A to the PointCloudGenerator node and Input B to the Read node for the source image.

See the Getting Started Guide for more information on Using the Viewer Controls.

5.   Proceed to Removing Rejected Points.
