Abstract
A method of controlling media projectors includes providing at least one electromagnetic detector having a field of view directed toward a three dimensional space, and photogrammetrically characterizing at least a portion of the field of view. There is provided at least one media projector that projects at least an electromagnetic signal and a projection controller that moves one or more media projectors in at least two dimensions. At least three measurement locations are obtained within the at least a portion of the field of view by moving the media projector in at least two dimensions. The at least one electromagnetic detector is used to detect the measurement locations within the three dimensional space using the electromagnetic detector to obtain photogrammetric data. The projection controller is calibrated based on the photogrammetric data.

32. A method of controlling media projectors, the method comprising the steps of:
-
providing at least one electromagnetic detector having a field of view directed toward a three dimensional space; photogrammetrically characterizing at least a portion of the field of view; providing at least one media projector that projects at least an electromagnetic signal; providing a projection controller that moves one or more media projectors in at least two dimensions; obtaining at least three measurement locations within the at least a portion of the field of view by moving the media projector in at least two dimensions; using the at least one electromagnetic detector to detect the measurement locations within the three dimensional space using the electromagnetic detector to obtain photogrammetric data; and calibrating the projection controller based on the photogrammetric data to project the media toward an arbitrary point in the three dimensional space. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47)
