marker-based AR

Marker-based augmented reality (AR) uses a physical marker, like a printed pattern or image, as a reference point. When a device's camera detects this marker, AR software precisely tracks its position and orientation in real time. This allows digital content—such as 3D models or information—to appear anchored to the marker, overlaying the real-world view. It enables interactive experiences where virtual objects accurately align with physical surfaces or objects, providing a seamless blend of digital and real world for applications like gaming, training, or visualization.
