Abstract
At least two cameras (10,12) view two points (A,B) displaced by a known distance on an article (S). Using a known relationship between two points (A,B) and the known position of cameras (10,12) in space the location of the viewed points (A,B) in space are determined by calculation. Similarly, the coordinates of other points on to article (S) are determined and hence dimensions such as width are determined.
