A method for generating a depth map includes acquiring at least one image of a scene including a reflective object or a semi-transparent object, acquiring, from the at least one image, a first depth map including a depth value for at least one opaque object which is reflected by the reflective object or viewed through the semi-transparent object, acquiring, from the at least one image, a second depth map including a depth value for the reflective object or the semi-transparent object, and generating a depth map for the scene based on the acquired first depth map and the acquired second depth map, and the generated depth map includes the depth value for the reflective object or the semi-transparent object and the depth value for the at least one opaque object which is reflected by the reflective object or viewed through the semi-transparent object.
