1. Introduction•Few of platforms are designed to

different tracking algorithms for AR system

•A novel tracking platform for AR environment, ARStudio, is proposed

•Augmented Reality, AR•Showing the virtual object in real

world

2. AR(1/7)

•AR base framework2. AR(2/7)

2. AR(3/7)•Marker tracking

2. AR(4/7)

2. AR(5/7)

•Markerless tracking2. AR(5/7)

2. AR(7/7)•Ambient light•Camera resolution•Image complexity•Image texture•Tracking angle

3. Platform design(1/3)

3. Platform design(2/3)

•Speeded Up Robust Features, SURF•Scale- and rotation-invariant

detector and descriptor•With distinctiveness, and

robustness•Can be computed and compared

much faster
