AR Registration is the spatial alignment process that anchors virtual content to real-world coordinates through Computer Vision, Sensor Input, and tracking algorithms.

Overview
AR Registration solves the fundamental challenge of placing virtual content into physical space with precision. Registration accuracy determines user experience quality—poor registration causes virtual content to float, jitter, or misalign with physical objects.
Registration Methods
-
Marker-Based: Fiducial markers (QR codes, image targets) providing known reference points
-
Markerless (Visual SLAM): Real-time camera and IMU fusion tracking environment features
-
Simultaneous Localisation and Mapping (SLAM): Creating spatial maps while determining device pose
-
Sensor Fusion: Combining camera, accelerometer, gyroscope, and magnetometer data
-
Cloud Anchors: Server-side spatial data enabling multi-device shared registration
Technical Challenges
-
Drift: Accumulated error in position tracking over time
-
Occlusion: Temporary loss of visual features due to obstruction
-
Lighting Variation: Feature extraction robustness under varying illumination
-
Dynamic Environments: Handling moving objects and changing scene geometry
