A visible symbol used as a reference point or measuring unit for positional tracking of Augmented Reality devices. It acts as an anchor to visually synchronize augmented virtual overlays onto the concrete world.

In AR, a fiducial marker is a visible object placed as a reference point for positional tracking of cameras, smartphones, or head-mounted displays. It helps translate spatial references between the concrete and augmented worlds, working as an anchor of scale, location, and orientation, which in turn allows for real-time virtual overlay.

It is often used as a black-and-white printed marker with specific geometric properties in the concrete environment but can also be a set of marks in the viewing instrument's reticle. Once the computer vision software recognizes a fiducial marker, it understands the device's relative position to its environment and knows in which direction any virtual intervention is projected.
