PURPOSE: A method for interpreting a 3D space from 2D images using a wide angle lens is provided to calculate the vector of a ray inputted to the lens which generated a pixel from each pixel composing the image displayed on a screen. CONSTITUTION: The vector of a ray inputted to a fish eye lens from a 2D coordinate, which presumed the central point of a fish lens image to be a starting point, is calculated. The position of an object at 3D space is measured using multiple fish eye lenses. A stereo vision is a technique to measure a 3D space using two or more cameras. The stereo vision is a technique to acquire xyz coordinates of a target in the 3D space using two or more wide angle lenses.
