Add marker-based alignments to the list?

[Chris45215]

I love this resource! Can materials on marker-based alignments be added to the list? Alignments based on markers are less prone to errors and shouldn't be as dependent on the other features within the pointclouds. Also, it allows for a marker to be designated as the origin for the pointclouds, which is helpful if the pointclouds are used for navigation.

Some papers on the subject include:
Visual Marker Guided Point Cloud Registration in a Large Multi-Sensor Industrial Robot Cell. https://ieeexplore.ieee.org/document/8449195/citations?tabFilter=papers#citations

Three-dimensional point cloud alignment detecting fiducial markers by structured light stereo imaging. By: Sandro Barone, Alessandro Paoli, and Armando Viviano Razionale.

Automatic Calibration of an Industrial RGB-D Camera Network Using Retroreflective Fiducial Markers. By: Atle Aalerud, Joacim Dybedal, and Geir Hovland.

It would be great to get some code examples of this process, but I have not found any yet. Though there are a number of repos for ICP implementations.
