View Full Version : Motion Analysis at night

01-30-2009, 12:25 AM
We want to capture automatic motion data on a real sports field or
court, but want to avoid the problem of infrared light from the sun. So
I'm thinking of something like this:

1. Reserve some outdoor ball field or court that has lights for
night games

2. Set up motion analysis cameras on tripods around a "test area"

3. When the sun sets, turn the stadium lights on

4. Attach reflective markers on each subject and test them.

Is this a crazy idea, or good idea? Does anyone have any experience or
insight about collecting motion data with reflective markers at night,
under artificial lighting?

Thank you, in advance. I will post a compilation of any responses I
