Abstract
An image processing system includes a camera, an image processor and a calibration surface including a calibration pattern, comprising plural alternately colored elements which provide a corresponding plurality of corners at locations at which more than two of the colored elements adjoin. The image processor detects from the video signal at least some of the corner locations and identifies a first and second group of lines of the calibration pattern, extrapolate the lines from each group and determine a on a plane of the scene as viewed by the camera, the presence and location of a first and second intersection points on where the extrapolated lines from the first and second groups, respectively, intersect to estimate one or more of a roll pitch and yaw angle of the camera relative to the calibration surface and extimates a likelihood that a corner is located at each of identified potential corner locations.
