Abstract:
1. A calibration and rectification method for a stereo camera, wherein a monitor is arranged vertically relative to the optical axis of the stereo camera, 3D patterns, similar to patterns obtained by projecting pattern images of various postures produced by a panel virtually located in front of the stereo camera, are displayed onto the monitor through a 3D graphical technique, and the stereo camera acquires the 3D patterns displayed on the monitor to perform calibration and rectification, thereby correcting images of the stereo camera, wherein the calibration and rectification method comprises; generating the 3D patterns through the 3D graphical technique; displaying the 3D patterns onto the monitor; acquiring, by the stereo camera, the 3D patterns displayed on the monitor, and transmitting information of the 3D pattern images to a computer; calculating calibration parameters from the transmitted pattern images; calculating a rectification parameter using the calibration parameters; transmitting the calibration parameters and the rectification parameter to the stereo camera; and transmitting pattern images, acquired by the stereo camera to which the calibration parameters and the rectification parameter are applied, to the computer to check the pattern images.
