Detection of Non-Stationary Photometric Perturbations on Projection Screens

Interfaces based on projection screens have become increasingly more popular in recent years, mainly due to the large screen size and resolution that they provide, as well as their stereo-vision capabilities. This work shows a local method for real-time detection of non-stationary photometric perturbations in projected images by means of computer vision techniques. The method is based on the co...

Generalization of Single-Center Projections Using Projection Tile Screens

This work presents an image-based approach to efficiently generate multiple non-planar projections of arbitrary 3D scenes in real-time. The creation of projections such as panorama or fisheye views has a number of possible applications, e.g., in geovirtual environments and in augmented reality. Our rendering technique is based on dynamically created cube map textures in combination with shader ...

Collimation in Transparent Projection Screens for Panoramic Augmented Reality Environments

There are many types of display systems used in Augmented Reality (AR), each having specific application areas. Based on an extensive literature and technology review, this paper proposes the use of a transparent projection screen for users in a fixed position observing distant objects. The transparent projection screen is similar to head-up displays (HUDs) used in aircraft cockpits, since they...
