Check2D is a software package that has been developed by the Centre for Sports Engineering Research at Sheffield Hallam University for use in 2D kinematic analysis. It uses the planar camera calibration technique from the OpenCV function library.
Check2D can be used to calculate the intrinsic and extrinsic
camera parameters (including lens distortion), and then reconstruct the
image coordinates into real world coordinates, in 2D kinematic analysis.
What do I need to use Check2D?
You need the following equipment to use Check2D:
- A flat checkerboard pattern. This is normally done on a printed sheet of white paper attached to a flat panel.
- One video camera. This can be any camera make/model.
- THE CHECKERBOARD MUST HAVE EQUAL NUMBER OF SQUARES IN BOTH DIRECTIONS.
- THE CHECKERBOARD SHOULD HAVE A WHITE BORDER WHICH IS ATLEAST AS WIDE AS
A SQUARE.
If you do not have this equipment, or just want to try the software, you can download some sample calibration images and sample trials from the download page.
