Object Calibration for Augmented Reality
Augmented reality involves the use of models and their associated renderings to supplement information in a real scene. In order for this information to be relevant or meaningful, the models must be positioned and displayed in such a way that they align with their corresponding real objects. For practical reasons this alignment cannot be known a priori, and cannot be hard-wired into a system. I...
متن کاملAffine Object Representations for Calibration-Free Augmented Reality
We describe the design and implementation of a videobased augmented reality system capable of overlaying threedimensional graphical objects on live video of dynamic environments. The key feature of the system is that it is completely uncalibrated: it does not use any metric information about the calibration parameters of the camera or the 3D locations and dimensions of the environment’s objects...
متن کاملCalibration-Free Augmented Reality
Camera calibration and the acquisition of Euclidean 3D measurements have so far been considered necessary requirements for overlaying three-dimensional graphical objects with live video. In this article we describe a new approach to video-based augmented reality that avoids both requirements: it does not use any metric information about the calibration parameters of the camera or the 3D locatio...
متن کاملPractical Calibration Procedures for Augmented Reality
Augmented Reality overlays computer generated images over the real world. This requires precise knowledge of the viewing projection of the headmounted display (HMD) and its position. Most of the previously published methods are complicated or use special equipment for the calibration process. We present a collection of calibration methods usable for fast and easy calibration of camera parameter...
متن کاملCalibration Requirements and Procedures for Augmented Reality
Augmented reality entails the use of models and their associated renderings to supplement information in a real scene. In order for this information to be relevant or meaningful, the models must be positioned and displayed in such a way that they blend into the real world in terms of alignments, perspectives, illuminations, etc. For practical reasons the information necessary to obtain this rea...
