Recalibration of a three-dimensional water quality model with a newly developed autocalibration toolkit (EFDC-ACT v1.0.0): how much improvement will be achieved with a wider hydrological variability? [PDF]
Geoscientific Model Development, 2023 Autocalibration techniques have the potential to enhance the efficiency and accuracy of intricate process-based hydrodynamic and water quality models. In this study, we developed a new R-based autocalibration toolkit for the Environmental Fluid Dynamics ...

A Unification of Autocalibration Methods
, 2000 This paper describes a unified theory for autocalibration of a moving camera. The camera models can be 2D projective, 2D affine camera and 1D projective projections. The scenes can be either non-planar scenes or planar scenes and the camera may also undergoes a pure rotation.

Robust Autocalibration of Triaxial Magnetometers [PDF]
IEEE Transactions on Instrumentation and Measurement, 2021 Self-calibration of a magnetometer usually requires controlled magnetic environment as the calibration output can be affected by field distortions from nearby magnetic objects. In this article, we develop a two-stage method that can accurately self-calibrate magnetometer from measurements containing anomalous readings due to local magnetic disturbances.

LINE OF SIGHT AUTO-CALIBRATION FOR CO3D ROLLING SHUTTER MATRIX DETECTOR [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 The accurate calibration of the line of sight (LOS) is very important for a high-resolution imaging satellite, especially in a system as Co3D, whose mission is to produce 3D elevation models.

Camera Calibration, Camera Autocalibration
, 2019 In this research seminar at the Escuela Politécnica Superior of the Universidad Autonoma de Madrid I will review the topics of camera calibration (providing an online demo) and autocalibration. I will provide an overview of the main steps of a standard structure-from-motion (SFM) pipeline and how camera calibration and camera auto-calibration fit into ...

Line Geometry and Camera Autocalibration [PDF]
Journal of Mathematical Imaging and Vision, 2008 We provide a completely new rigorous matrix formulation of the absolute quadratic complex (AQC), given by the set of lines intersecting the absolute conic. The new results include closed-form expressions for the camera intrinsic parameters in terms of the AQC, an algorithm to obtain the dual absolute quadric from the AQC using straightforward matrix ...

AUTOMATIC CAMERA ORIENTATION AND STRUCTURE RECOVERY WITH SAMANTHA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 SAMANTHA is a software capable of computing camera orientation and structure recovery from a sparse block of casual images without human intervention. It can process both calibrated images or uncalibrated, in which case an autocalibration routine is run.
