Catadioptric camera calibration using geometric invariants
Proceedings Ninth IEEE International Conference on Computer Vision, 2003Central catadioptric cameras are imaging devices that use mirrors to enhance the field of view while preserving a single effective viewpoint. In this paper, we propose a novel method for the calibration of central catadioptric cameras using geometric invariants.

Geometric calibration of thermal cameras
SPIE Proceedings, 2013There exist several tools and methods for camera resectioning, i.e. geometric calibration for the purpose of estimating intrinsic and extrinsic parameters. The intrinsic parameters represent the internal properties of the camera such as focal length, principal point and distortion coefficients.

Geometric algorithms for closed chain kinematic calibration
Proceedings 1999 IEEE International Conference on Robotics and Automation (Cat. No.99CH36288C), 2003We develop a high-level, unified framework for the calibration of kinematic chains containing closed loops, passive joints, and an arbitrary number of actuators. Our approach rests on viewing the configuration space of the kinematic chain as an embedded sub-manifold of an ambient manifold, and formulating error measures based on the natural metric in ...

Geometric calibration and geolocation of airborne SAR images
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012The research focuses on airborne SAR geometric calibration. Based on Range-Doppler (RD) model, mathematical model of airborne SAR image pixel direct geolocation was derived and objective calibration parameters were determined. A whole geometric calibration procedure was proposed, whose critical techniques had been studied.

Geometric camery calibration: the virtual camera approach
Machine Vision and Applications, 1995Accurate dimensional measurements made with TV cameras require a careful geometric calibration of the imaging device. This work presents a new calibration approach that makes use of the virtual camera paradigm, in which a calibrated surface (target) plays the role of the image plane of a distortionless, fictitious camera.

Novel Geometric Technique of Ultrasound Probe Calibration
2018In the study a novel, simple and robust calibration technique of ultrasound probe for image-guided navigation systems has been proposed. The method employs a LEGO phantom with known geometry and is much simpler than other commonly used methods. Additionally, it requires only a single US image.
