In this chapter we discussed how to restrict the projective ambiguity of the reconstruction to metric (i.e. Euclidean up to scale). After a brief discussion of traditional calibration approaches, we focussed on the problem of self-calibration. The general concepts were introduced and the most important methods briefly presented. Then a flexible self-calibration approach that can deal with focusing/zooming cameras was worked out in detail.
