I’ve been using IR cameras in 2010, then just kinect until today. I have a proposal for a theatrical performances where I should track dancers from above, that is, only blob tracking. So the stage becomes an interactive floor. I was thinking to use kinect because I made many interactive installations with it, but reading this post
I’ve found that it could not be the best solution. Probably IR camera can do better in this particular situation.
- it doesn’t require any lighting,
- No problems with other lights on stage.
- just set near/far and blob detection works like a charm.
- only 30 fps,
- limited size of the interactive area on stage because FOV is not very wide.
- video signal is hard/expensive to extend from the stage to the theatre control room.
- can reach 60 and more fps -> it can follow the dancer’s moves
- can have a very wide angle lens -> it can cover the entire stage without requiring multiple cameras systems
- can send signals over ethernet -> video signal cover any distance
- very sensible to light conditions
- stage must be IR illuminated
- stage must results almost “black” and bodies must result almost “white” otherwise no blob tracking.
So, which is the best solution?
