The present work reports self-illumination correction procedure and results of its experimental testing on a simple model. In the procedure reflectivity value is assessed directly from the set of model images captured at wind-off conditions with different reflecting surfaces covered or removed. The paper covers the theoretical part of the problem and describes exact implementation of a processing sequence, which included image mapping on a 3-D surface, building a mesh of surface elements, evaluation of radiative exchange between elements and calculation of the corrected brightness map.
