Abstract
Estimating lighting conditions in a mixed reality scene is a challenging task. Adding shadows cast by virtual objects in the scene contributes significantly to the user experience. To this end, there is proposed, among others, a method for an autonomously movable device having a camera. The device may move to a first position in the scene and capture a first image of a shadow of the device cast by a light source. The device may move to a second position in the scene and capture a second image of a shadow of the device cast by a light source. Features of the light source may be determined at each of the first and the second positions, and a lighting model may be determined for the scene based on the determined features of the light source in the scene.
