Computer-vision-based registration techniques for augmented reality (original) (raw)

Augmented reality is a term used to describe systems in which computer-generated information is superimposed on top of the real world; for example, through the use of a see-through head-mounted display. A human user of such a system could still see and interact with the real world, but have valuable additional information, such as descriptions of important features or instructions for performing physical tasks, superimposed on the world. For example, the computer could identify objects and overlay them with graphic outlines, labels, and schematics. The graphics are registered to the real-world objects and appear to be "painted" onto those objects. Augmented reality systems can be used to make productivity aids for tasks such as inspection, manufacturing, and navigation.
