  • Method and device for aligning color channels
    Patent number: 11611732
    Abstract: A method of aligning a plurality of color channels of a projector is provided. The method includes: for each color channel, (i) projecting test pattern on a surface; (ii) capturing image of the test pattern generated on the surface; and (iii) adding the captured image to an image set. Once the captured images for each color channel are added to an image set, identifying a reference position based on the image set. This is followed by processing the image set to estimate a divergence of the respective test patterns for each color channel with respect to the reference position, followed by computing a corrective function for each color channel and applying the respective corrective function to each color channel to align the color channel to the reference position.
