Abstract
One exemplary aspect relates generally to camera calibration and, more particularly, to methods and systems for performing single-shot single or stereo camera calibration of wide-angle or fisheye camera pairs using a specially arranged calibration target. One exemplary advantage is that the system provides a technique for calibrating fisheye or wide-angle camera(s) without requiring multiple viewpoints.

A single-shot calibration system, comprising:
- at least one camera having a wide-angle or fisheye lens;
- a hanging marker array including a plurality of markers suspended by thin or transparent threads at different heights, each marker having a known three-dimensional location relative to a reference frame;
- and
- a computing device configured to:
- capture a single image of the hanging marker array from said camera,
- detect two-dimensional locations of the markers in the single image,
- map each detected two-dimensional location to its associated known three-dimensional coordinate, and
- solve for intrinsic and/or extrinsic calibration parameters of the camera using only data from the single image.
