SYSTEM AND METHOD FOR CALIBRATING CAMERA POSITION IN A COMPUTER VISION-BASED SELF-SERVICE CHECKOUT TERMINAL

Abstract: a system and method for camera position calibration in a terminal. a camera has a predefined expected orientation with respect to a scan zone for the terminal such that a target zone (the scan zone or an outline thereof) appears in a predefined position within a field of view of the camera. the video output signal from the camera is combined by a processor with an overlay image file. the overlay image file has a nontransparent section and a transparent section corresponding to the predefined position of the target zone within the field of view of the camera. the video output signal is combined with the overlay image file so that the display shows an actual orientation of the camera with respect to the target zone overlaid with the overlay image file. this allows the position of the camera to be adjusted to match the predefined expected orientation.
