Abstract
A system and method for aligning stacked projectors is provided. A computing device is in communication with at least two projectors, configured to project images stacked onto each other, and at least one sensor configured to acquire respective images the projector images. Respective initial positions in a common space are determined of each of the projector images, from the sensor images, as well as a virtual projector image located at a common target position. Respective transforms for each of the projector images to one or more of shift and transform the projector images to the common target position of the virtual projector image. The respective transforms are applied to further first projector images to produce respective transformed projector images. The projectors are controlled to project the respective transformed projector images according to the common target position.
