Methods, systems, and computer program products for imperceptibly embedding structured light patterns in projected color images for display on planar and non-planar surfaces
First Claim
1. A method for embedding a structured light pattern in a color user image and for projecting the user image, the method comprising:
- (a) varying pixel intensity values for a first visible light color in a color user image so that pixel polarities encode a first structured light pattern during a selected image exposure period and so that varied pixel intensity values have a predetermined relationship with respect to original pixel intensity values in the user image;
(b) projecting the user image with the embedded structured light pattern onto a surface; and
(c) detecting the first structured light pattern during the image exposure period.

Abstract
Methods, systems, and computer program products for imperceptibly embedding structured light patterns in projected color images for display on planar and non-planar surfaces are disclosed. According to one method, an image exposure period for detecting an embedded structured light patterns in a projected image is selected based on analysis of pixel polarities for different pixel intensities of a pixel color. Pixel intensities for the color are varied in the user image so that pixel polarities encode the structured light patterns during image exposure period. The user image is projected with the structured light patterns onto the surface. Depth information is continuously acquired and used to adjust display of the user image.
