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

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

(English) Multi-projectors for arbitrary surfaces without explicit calibration nor reconstruction

Abstract This paper presents a new approach allowing one or more projectors to display an undistorted image on a surface of unknown geometry. To achieve this, a single camera is used to capture the viewer’s perspective of the projection surface. … Continue reading
