3D IMAGING WITH LINE-SCANNING

摘要

Apparatus and a method for producing a stereoscopic line-scan image of an object in which a detector camera is used to view the object, means are provided to move relative to one another the surface of the object past the detector in a direction which is at right angles to the scanning lines direction of the detector, and means are provided to select the outputs from two spaced lines in each picture frame produced by the detector and store those lines in a frame store to build up individual pictures from each of the two lines, so that one individual picture constitutes a left hand picture of a stereoscopic pair and the other individual picture constitutes a right hand image of a stereoscopic pair. Preferably the detector camera is a television camera or a full field digital.
