Abstract
A photography and thermography combining method of obtaining, for a chosen spectacle frame model of a spectacle wearer, at least one fitting parameter to fit an ophthalmic lens into the spectacle frame model. The method includes taking a photograph of the wearer's face with spectacles having the chosen spectacle frame model, taking a thermogram of the wearer's face with the spectacles, identifying the spectacles' contour in the thermogram, overlaying the identified contour or a boxing shape derived from the identified contour onto the photograph, thus obtaining a composite image, and obtaining the at least one fitting parameter from the composite image.
