Calibration-Free Projector-Camera System for Enhanced Spatial Augmented Reality on Planar Surfaces

This study presents a novel calibration-free system for spatial augmented reality that overlays images from a projector onto dynamic textured planar surfaces. Utilizing an Inverse Lucas-Kanade approach, our method allows for independent motion of the projector and camera without requiring prior calibration between them. Key contributions include real-time tracking of target surfaces, effective image projection with corrections for rotation, translation, and perspective distortions. The results demonstrate significant advancements in seamless augmented reality experiences on various surfaces.
