camera calibration with distortion models and accuracy evaluation

PDF	A Precision Analysis of Camera Distortion Models 5 juil 2017 · High- precision camera distortion measurements with a “calibration harp” Camera calibration with distortion models and accuracy evaluation

PDF	Camera calibration with distortion models and accuracy evaluation In this paper we present a camera model that accounts for major sources of camera distortion namely radial decentering and thin prism distortions The

How do you handle distortion in camera calibration?
The most widely used camera calibration algorithm is the Zhang algorithm ¹ that iteratively finds correspondences between the coordinates of some easily identifiable feature points (usually inner corners) of a known object (a planar pattern) in both the image plane and the scene.
How do you evaluate camera calibration?
Camera calibration parameters
f - Focal length measured in pixels (in pixels). cx, cy - Principal point coordinates, i.e. coordinates of lens optical axis interception with sensor plane (in pixels). b1, b2 - Affinity and non-orthogonality (skew) coefficients (in pixels).
