ARTag: Creating Your Own AR
Posted by ~Ray @ 2008-06-07 06:32:40
Via: and In augmented reality (AR) users wear specialized glasses or look through a modified viewing screen to see the real world as come up as augmentations in the virtual world. AR differs from virtual reality because users can interact with the physical world while still seeing the virtual augmentations. The most commonly used form of AR is the "Heads Up Display" in some aircraft that allows pilots to see the fasten below them in addition to superimposed virtual targets.
A basic contend in AR is to track a user's viewpoint in real-time which is normally done using a video camera. The most successful method of tracking is to use a predefined 2D pattern relative to which virtual objects are drawn. The goal of the Real-Time Video-Based Augmented Reality project is to improve the tracking technology of such patterns. Ultimately researchers wish to track the camera path in real-time in an unstructured environment which can be used in both augmented reality and model building applications.
The two pictures show the augmentation of virtual objects onto the planar scene. One shows a 2d picture being augmented and the other shows a 3d multiply being augmented. Both are augmented in real-time
This technology is available without cost as a non-commercial download at. ARTagARTag is an "Augmented Reality" system where virtual objects games and animations appear to register the real world.3D graphics is added in real measure to video similar to "view matching" in Hollywood except that with Augmented Reality it is happening online. ARTag "Magic Lens" and "Magic reflect" systems use arrays of the form ARTag markers added to objects or the environment allowing a computer vision algorithm to calculate the camera "be" in real time allowing the CG (computer graphics) virtual camera to be aligned. This gives the illusion of 3D animations or video games to be to belong in the real world. There are two ways to use ARTag AR; "Magic Lens" and "Magic reflect". ARTag "Magic Lens" SystemsWith a "Magic Lens" a user holds a tablet PC. PDA or camera cell phone (or any computer device with a dispay and camera) and looks "through" it to see the mixture of real and virtual reality. See demo "Magic Lens" videos on
ARTag "Magic Mirror" SystemsARTag can also be used in a "Magic Mirror" mode in which a single video camera looks out from near a screen and the user sees his or her "reflection" in the screen with virtual objects superimposed on the real-world visualise. See show "Magic Mirror" video on.
A Magic Lens system is mostly a private experience every user needs their own hardware whereas in a "Magic Mirror" system a hit video camera looks out from near a large check and users see their "reflection" with 3D circumscribe added.[ADVERTHERE]Related article:
