Abstract
A method and apparatus for determining the range of an object. A first image of at least a portion of the object viewed from a first position is generated. A second image of the portion viewed from a second position spaced apart from the first position is generated by calculation from the first image and the distance between the first and second position. It is assumed that all of the portion represented by the first image lies on a radius less than the distance to the object. A third image of the portion viewed from the second position is generated and the range determined by comparison of the first and third images.
