005 - Camera and projector alignment
As demonstrated more accutely during the Interactive Trial Dec 2005, the different aspect of the filmed stage and the projected stage is a key issue to resolve. Multiple iterations (video feedback) of a given projected object will always occur unless the two are perfectly aligned. An obvious and relatively easy solution is to distort the projected image at the Interface level.
With precise measurements made of the stage area and the distance and position of the camera and projector, the Interface layer could be contorted (keystoning etc) to take into account a 3 dimensional area. A ceiling mounted camera with matrix abstraction could be used to get the performers distance to projector amount, the value of which would provide focus and positional information.
This would also require a method of Initialising the alignment prior to performance.
