Projected texture

Calibration-free Projector-Camera System for Spatial Augmented Reality on planar surfacesTakayuki Nakamura, Francois de Sorbier, Sandy EggiMartedi, Hideo Saito

Goal

Overlay an image from a projector onto a textured and moving planar surface

Tracking of the target surface and the projected image

based on an Inverse Lucas-Kanadeapproach

Method

  • No calibration of the projector/camera pair

  • Camera and projector can be moved independently

Contributions

Camera

Target surface
