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
