Abstract

A method of taking three-dimensional measurements of an object surface by means of a camera movable between initial and terminal positions relative to the object surface in which object coordinates are determined by gray scale curves of images formed on sensors of the camera.Tracking of characteristics of an image taken at an initial position to an image taken at a terminal position is made safer and simpler by incremental tracking over one or more images taken at camera positions intermediate the initial and terminal positions.
