  • Motion Analysis at night

    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
