Abstract The results of an extensive project on infrared photometry of Cepheids in our Galaxy, the Large Magellanic Cloud and the Small Magellanic Cloud are described. The principal aims were to examine the structure of the LMC and the SMC, to determine the intrinsic properties of Cepheids in the Clouds, to derive the infrared period-luminosity and period-colour relations from the combined data of the three galactic systems, to derive distances to the Clouds and to obtain accurate Cepheid radii from an application of the Baade-Wesselink technique in the infrared. All Galactic calibrating Cepheids south of +30° were included in the programme. The large number of Galactic Cepheids with high precision infrared photometry enabled an investigation and understanding of the systematic discrepancies in the derivation of Baade-Wesselink radii. In almost all of the scientific aims it is apparent that infrared photometry has significant advantages over optical photometry in deriving results of higher precision and freer of systematic effects.
