Abstract

PURPOSE: To accomplish a stereo scopic method capable of preventing three- dimensional coordinates of a feature point from deviating remarkably by providing at least three units of image pickup means, allowing object point images to correspond to each picture and detecting erroneous correspondence of the object point images.
CONSTITUTION: Object point imges P1, P2 and P3 with respect to a feature point P are displayed on pictures of three units of television cameras. An image l2 (called epipolar line) of a straight line F1P1 connecting a fcus F1 of the 1st camera and the object point image P1 is set on the 2nd picture 20. In a simular manner, epipolar lines l3 and m3 of the straight line F1P1 and a straight line F2P2, respectively are set on the 3rd picture 30. Thus when performing the correspondence between respective pictures of object point imges is performed by utilizing an epipolar line and when coordinates of respective object images P1, P2 and P3 are set in respective pictures, three coordinate data can be obtained from respective object point images P1, P2 and P3 in respective pictures, and processed statically, whereby three-dimensional coordinates of the feature point P can be calculated.
