Abstract:
1. A method for physically aligning a pair of digital cameras relative to each other, without the use of a pre-existing calibration image, to produce a three dimensional image, said method comprising: a) mounting said digital cameras on a mobile platform that experiences at least one of motion and vibration; b) aiming a first digital camera at a target to produce a first image comprised of a first plurality of pixels; c) aiming a second digital camera spaced apart from said first digital camera at said target to produce a second image comprised of a second plurality of pixels; d) using known distances of said target from each of said digital cameras to analyze positions of one of said first and second pluralities of pixels relative to the other; e) using said positions of said pluralities of pixels of said first and second images to generate calibration signals that form an image offset value to alter at least one of said first and second images derived from said target, to thereby account for physical misalignment of one of said digital cameras relative to the other, without reference to a pre-existing calibration image.
