ABSTRACT:
An optical distance measurement device for determining the distance to a object 5 exhibiting a bilateral symmetry, such as an automobile, includes two optical systems whose optical axes are separated by a lateral distance perpendicular to the axis of symmetry of the object 5. Two images are formed upon the image sensors 3 and 4. A window formed within each image having a width substantially corresponding to the width of the object 5 is successively shifted from left to right within the image, and the symmetry with respect to the central axis thereof is evaluated by the microcomputer 10 at each position of the window. The axis position at which the evaluated degree of symmetry is the greatest is determined for each image. The distance to the object 5 is determined from the amount of shift between the two axis positions, based upon the principle of trigonometry.
