Abstract

A device for scanning the surface of an item comprising a scanning zone and means for projecting a pattern of light dots onto the surface to be scanned when it is in the scanning zone. Means are provided for detecting the pattern of light dots. Means are also provided for making a grey scale image of the surface, and means are provided for combining the light dot pattern with the grey scale image to create a two dimensional reproduction of the item that was scanned.

A method of scanning and capturing the image of a surface which surface has a plurality of features and each feature being in a particular place on the surface. The method comprises placing an object which surface is to be scanned in a scanning zone and placing a plurality of reference points on the surface so that some of the reference points correspond to some of the features. The location of the features on the surface is determined by locating the reference points that correspond to the features so that the image is captured.
