Markerless AR

Definition

Markerless AR, or markerless augmented reality, is a technology that overlays digital information onto the real world without the need for physical markers or predefined targets. This allows for a more flexible and dynamic interaction with virtual objects, as users can experience augmented content based on their location or orientation, rather than being tied to specific markers. This technology is often driven by advanced computer vision and spatial mapping techniques.
