    Abstract: An illuminant estimation method, including acquiring two image frames, wherein a distance between the two image frames is greater than a predetermined distance; detecting shadows included in the two image frames, extracting pixel feature points corresponding to the shadows, determining point cloud information about the shadows, and distinguishing a point cloud of each shadow based on the point cloud information about the shadows; acquiring point cloud information about multiple objects, and distinguishing a point cloud of each object based on the point cloud information corresponding to the multiple objects; matching the point cloud of the each shadow and the point cloud of the each object in order to determine corresponding shadows associated with the multiple objects; and determining a position of an illuminant according to a positional relation between the multiple objects and the corresponding shadows.
