Invisible or Low Perceptibility of Image Alignment in Dual Projection Systems
First Claim
1. A method comprising:
- accessing an alignment pattern having at least one alignment feature;
modifying a portion of image content in a frame of a first digital image sequence by a projection system using the at least one alignment feature; and
spatially aligning the first digital image sequence and a second digital image sequence based on the portion modified by the projection system when displaying the first digital image sequence and the second digital image sequence.

Abstract
A dual projection system can align displayed images using an alignment pattern. The alignment pattern can be used to modify part of an image content frame of an image data sequence. Two image data sequences can be spatially aligned based on the modification to part of the image content frame using the alignment pattern. An image content frame may be warped and displayed. The displayed warped image content frame can be captured. A set of transformation vectors can be determined based on the captured image content frame and alignment image data. Stored transformation data can be updated using the set of transformation vectors and the updated transformation data can be used to spatially align two image data sequences.

12. A method, comprising:
-
capturing, as a captured first image sequence frame, a displayed first image sequence content frame having image content modified with alignment data; capturing, as a captured second image sequence frame, a displayed second image sequence frame having image content modified with the alignment data; determining a set of transformation vectors based on a spatial difference between the alignment data in the captured second image sequence frame and the captured first image sequence frame; spatially aligning a displayed first image of a first image sequence and a displayed second image of a second image sequence using the set of transformation vectors. - View Dependent Claims (13, 14, 15, 16, 17, 18)
