WebA scan context descriptor is a 2-D global feature descriptor of a point cloud that can be used to detect loop closures. The function computes the descriptor by first binning points from a 3-D point cloud scan into concentric radial and azimuthal bins, and then selecting the maximum z -height of points in each bin.
