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

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

Plane-Based Calibration for Linear Cameras

stack

Abstract Linear or 1D cameras are used in several areas such as industrial inspection and satellite imagery.Since 1D cameras consist of a linear sensor, a motion (usually perpendicular to the sensor orientation) is performed in order to acquire a full … Continue reading

Calibration of Cameras with Radially Symmetric Distortion

calibicon

Abstract We present algorithms for plane-based calibration of general radially distorted cameras. By this we understand cameras that have a distortion center and an optical axis such that the projection rays of pixels lying on a circle centered on the … Continue reading

(English) Plane-based Self-calibration of Radial Distortion

iccv2007icon

Abstract We present an algorithm for plane-based self-calibration of cameras with radially symmetric distortions given a set of sparse feature matches in at least two views. The projection function of such cameras can be seen as a projection with a … Continue reading

Self-Calibration of a General Radially Symmetric Distortion Model

radial

Abstract We present a new approach for self-calibrating the distortion function and the distortion center of cameras with general radially symmetric distortion. In contrast to most current models, we propose a model encompassing fisheye lenses as well as catadioptric cameras … Continue reading
