On the subject of the kinect

1) Polycarb is a nuisance for using any type of light based image, laser/structured ir/visible light
2) While the events are indoors, that doesn't mean a healthy amount of sunlight won't make it into the play spaces. I've got video from 2014 from our IR camera in an auditorium with sunlight blooming out the targets coming from an open gym door. Similarly many popular event lighting chemistries emit large amounts of IR
3) During 2012, the first year you could use the kinect, our team tried using it to track balls in flight. The problem is that the color image and the depth images are slightly out of sync. So an approach to say, find the orange region of the image, then figure out how far away it is becomes non trivial. Going from a stereo disparity map keeps those in sync
