For research in the field of illumination estimation and colour constancy, there is a need for ground truth measurement of the illumination colour at many locations within multi-illuminant scenes. This talk proposes a practical approach to obtaining such ground truth illumination data. The method involves using a drone to carry a grey ball of known percent surface spectral reflectance throughout a scene while photographing it frequently during the flight using a calibrated camera. In total, the dataset contains 30 scenes with 100 illumination measurements on average per scene, which is available for free download.
