PURPOSE:To obtain securely execution information on a feature line by coordinating stable connection line component or line segments which are hardly influenced by noise according to all their features, and coordinating respective points on the basis of the result. CONSTITUTION:Original image input devices 21 and 22 each consist of a TV camera, AD converter, and frame memory in combination, and line drawing extracting circuits 23 and 24 performs threshold processing of results based upon Laplacean to perform binary coding processing. A parallax offset detecting circuit 25 calculates the quantity of shifting so that the mutual correlation between a right and a left original image is maximum. It is considered that line segments at segment extracting circuits 26 and 27 are between terminal points, branch points, or maximum points of a line component of 1 in thickness. A feature point coordinating circuit 29 coordinates singular points of the same height among feature points on single segments or composite segment of the coordinated right and left images. A depth calculating circuit 30 calculates the depth corresponding to the coordinated feature points and identifies the body. |
