Coverage

This node reports the estimated view-based coverage score for this object instance. A coverage of 1 means a perfect match, i.e. all pixels of the visible object parts contain a point of the point cloud within the specified CoverageDistanceThreshold around the CAD model surface. A coverage of 0.5 means that half of the pixels in the point cloud are missing; this can be due to occlusion by other parts, missing data due to reflections, or simply because the CoverageDistanceThreshold was set too low and the points are not considered to be on the surface due to point cloud noise.

Format

Number

Percentage of CAD model pixels in this orientation which are covered by point cloud points.

Note

The coverage estimation depends strongly on the internal PartFinder algorithm of sampling points from a 3D surface. Therefore, the absolute value of this score can vary significantly depending on the version of the SDK.
