What are fiducial markers How is it used in AR applications?

In order to make the computer vision problem simpler, many AR applications utilize landmarks that are placed artificially into the environment that are images that the application can easily recognize. Images used specifically for this purpose are called fiducial markers, and sometimes fiducial symbols.

What are fiducial markers computer vision?

A fiducial marker or fiducial is an object placed in the field of view of an imaging system that appears in the image produced, for use as a point of reference or a measure. It may be either something placed into or on the imaging subject, or a mark or set of marks in the reticle of an optical instrument.
