Capturing Non-Periodic Omnistereo Motion

omnicalib

Abstract An omnistereo pair of images enables depth perception all around the observer. Because omnistereo lenses or mirrors do not yet exist, capturing an omnistereo video would require using several stereo cameras at different baseline orientations. This paper presents a … Continue reading

Geometric Video Projector Auto-Calibration

shapeimage_1

Abstract I this paper we address the problem of geometric calibration of video projectors. Like in most previous methods we also use a camera that observes the projection on a planar surface. Contrary to those previous methods, we neither require … Continue reading

Virtual 3D drawing tool for stage performances

vric_icon

This paper presents a new system for tridimensional virtual drawing relying on an infrared pen observed by a number of surrounding cameras. Nintendo wiimotes are used as cameras to provide reliable real-time tracking information. Continue reading

Improving Border Localization of Multi-Baseline Stereo Using Border-Cut

Abstract This paper presents a novel algorithm that improves the localization of disparity discontinuities of disparity maps obtained by multi-baseline stereo. Rather than associating a disparity label to every pixel of a disparity map, it associates a position to every … Continue reading

Projector Calibration Using a Markerless plane

wall-camera homography

Abstract In this paper we address the problem of geometric video projector calibration using a markerless planar surface (wall) and a partially calibrated camera. Instead of using control points to infer the camera-wall orientation, we find such relation by efficiently … Continue reading
