Patent ID: 7139424

Claim:
A stereoscopic image characteristics examination system for examining the characteristics of a stereoscopic image captured by a stereo camera having a plurality of cameras and for generating correction data, the system comprising: an examination screen having a grid pattern including a plurality of grid lines and a background, each of a plurality of intersections of the grid lines defining a grid point, and said screen arranged in a shooting direction of the stereo camera; and means for obtaining the coordinates of each grid point on each of a pair of images constituting a stereoscopic image obtained by photographing the examination screen with the stereo camera, the images corresponding to the respective cameras constituting the stereo camera, and for generating correction data for correcting a variation in the characteristics of the stereoscopic image in order to detect a correct parallax, the correction data being generated on the basis of the obtained coordinates and the corresponding ideal coordinates previously stored of each grid point, the variation being caused by at least the characteristics of the stereo camera.
