Abstract
An automatic machining or assembly system including a comparator for comparing the intensity of a pixel in a first image of a scene produced by a sensor with a corresponding pixel and pixels increasingly displaced from the corresponding pixel in a second image of the same scene displaced with respect to said first image and for producing signals representing image depth the magnitude of which is determined by the relative displacement of compared pixels having minimum intensity variation or by a second sensor linearly displaced from the first sensor or by optical diffraction means between the first sensor and the scene, when rotated to a new position.
