A method which has not received high prominence in the machine vision community is that of multi-camera measurement. There are advantages to be gained from using multi-camera views: (i) redundancy of measurement; (ii) statistical feedback; (iii) full modelling of all parameters; (iv) mature understanding of the method; (v) wide acceptance of the technique; and (vi) known performance. Against these advantages are: (i) the high level of computation; (ii) the setting up for each measurement case; (iii) a high degree of `expert knowledge' required; (iv) the lack of techniques for fast or dynamic automated measurement. This paper describes the basic method of photogrammetry and discusses the potential for automated high accuracy measurement in an industrial context
