Abstract
An augmented reality tool makes use of autocalibrated features for rendering annotations into images of a scene as a camera moves about relative to the scene. The autocalibrated features are used for positioning the annotations and for recovery of tracking, correspondences and camera pose. An improved method of autocalibration for autocalibrating structured sets of point features together is also described. The augmented reality tool makes use of manual, semi-automatic and automatic methods employing autocalibrated features.
