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

(English) A MRF formulation for coded structured light

icon_tardifj_markovianstl_3dim05

Abstract Multimedia projectors and cameras make possible the use of structured light to solve problems such as 3D reconstruction, disparity map computation and camera or projector calibration. Each projector displays patterns over a scene viewed by a camera, thereby allowing … Continue reading

(English) Projector-Based Augmented Reality in Surgery without Calibration

Abstract Augmented reality (AR) is becoming an important tool in surgery to support the surgeon and improve operation quality, safety and duration. However the AR setup with head-mounted display (HMD) and other equipments is often considered cumbersome by surgeons and … 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
