Method and system for constructing illumination adaptive map of indoor scene and estimating unknown light settings using same

The invention relates to a method and a system for constructing an illumination adaptive map of an indoor scene and estimating unknown light settings using the same. The invention relates to a computer-implemented method for constructing an illumination adaptive map of an indoor scene, the scene comprising at least one light source and at least one surface, where the illumination adaptive map adjusts its appearance based on a given light setting; wherein the light setting is defined by the state of each light source, the method comprising: obtaining first image information of the scene wherein all light sources are turned on, estimating a map of the scene based on the first image information, the map comprising light reflection characteristics and radiance information of a surface in the scene, each light source in the scene is detected and segmented based on the estimated map, a radiance contribution of each light source to the scene is estimated based on the estimated map, and an illumination adaptive map i
