Modeling for projection-based augmented reality system
A method includes sending, to an interaction device including a projector and a camera, instructions causing the projector to project a light pattern to each of one or more specified directions and receiving, from the interaction device, one or more images each including illumination patterns associated with one or more surfaces of a specified direction. The method also includes constructing, based on the projected light patterns and the received illumination patterns, a model describing an environment of the interaction device, where the model includes one or more characteristics of each of one or more objects in the environment and one or more characteristics of each of one or more surfaces in the environment.
