We propose a method to estimate a position of a light source by using a single RGB-D image. First, highlights on scene object surfaces are detected by using depth information and luminance histograms. Next, light vectors (incident angles) are computed from normal vectors of the detected highlights and viewing vectors. Finally, the intersection of light vectors is calculated for estimating a three-dimensional position of the light source.
