Title:
- Diminishable Visual Markers on Fabricated Projection Object for Dynamic Spatial Augmented Reality
Description:
Spatial augmented reality (SAR) is a projection technology to add optical illusion onto static objects. Generally, in SAR, images are projected on complex everyday surfaces other than a flat projection screen. Thus, geometric correction of images is essential. Many studies have examined geometric correction of projection images on nonplanar surfaces. If a projection surface shape is known, it is possible to correct images geometrically by calibrating intrinsic parameters of the projector and extrinsic parameters (position and pose relationships) between the projector and surfaces. However, it is difficult to directly apply previous geometric correction methods to dynamically moving surfaces, because these methods generally assumed only static surfaces.
