Check3D is a software package that has been developed by the Centre for Sports Engineering Research at Sheffield Hallam University. It uses the planar camera calibration technique from the OpenCV function library.
Check3D allows the user to calculate the three dimensional (3D) position
of a marker (point on a tennis racket, marker on a shoe, etc.)
Images from two syncronised cameras are feed into the software and
relevant markers are digitised in both images. A camera
calibration model is used to reconstruct the 3D position
of the marker from the image coordinates digitised from the the camera
images.
What do I need to use Check3D?
You need the following equipment to use Check3D:
- A flat checkerboard pattern. This is normally done on a
printed sheet of white paper attached to a flat panel.
- Two synchronised cameras. These can be any camera make/model as long as they can produce a sequence of still images.
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.
