ARTag : SDK demonstrating AR

Demo AR Programs using ARTag

There are four main programs demonstrating AR (augmented reality) using ARTag; , <3d_augmentations>, and . The first two have two versions, one with “_usb.exe” for most cameras such as USB webcams, and the second “_dragonfly.exe” is for the Point Grey Dragonfly camera from Point Grey Research (www.ptgrey.com) often used in university labs that gives better performance and was used by myself in ARTag development.

1. The program uses the “base0” image and just draws a few graphics primitives and a textured logo image relative to the marker array, its purpose is to be a simple example for people programming with the SDK.

2. The <3d_augmentations> demo is more interesting, it was used to create the images at the first page of this document. This program uses the “base0” array, and the individual toolbars. To save space in the download, and for permission reasons, only 5 models are provided in the demo and SDK download; fish, Chihuahua, car, frog, and can of asparagus model.

If you run this application, aim the camera at the base0 and toolbar arrays and you should see 3D virtual objects rendered relative to them.
Fiala (2004) has developed new system called ARTag was inspired by ARToolkit. ARTag was taking advantage of the increased computing processing power available. ARTag uses more complex image processing and digital symbol processing to achieve a higher reliability and immunity to lighting
