Abstract
A computer-implemented system and method of reproducing visual content are described. The method comprises capturing a reference image of a calibration pattern projected on a surface at an initial position and at an offset position, the offset position relating to a projection offset from the initial position by shifting the calibration pattern a predetermined amount; and determining, using the reference image, a spatial capture offset for the calibration pattern between the initial position and the offset position, the spatial capture offset measuring a spatial shift of the calibration pattern in the reference image. The method further comprises determining a scale using the spatial capture offset and the projection offset; decoding a portion of a captured image, the captured image including the visual content and the calibration pattern, to determine a position within the calibration pattern by applying the determined scale, and reproducing the visual content based on the determined position.
