1. A method implemented by a system of one or more computers, the method comprising:
obtaining a plurality of images of a real-world object, the images being obtained from a plurality of image sensors positioned about the real-world object, and the images depicting projection spots projected onto the real-world object via a plurality of projectors positioned about the real-world object, each projection spot representing an intersection of a cone of light projected by one of the projectors with the real-world object;
accessing a projection spot map, the projection spot map being based on geometric information associated with each cone of light and including information usable to determine real-world locations of projection spots based on depictions of the projection spots in the obtained images;
assigning location information to the projection spots based on the projection spot map; and
causing generation of a three-dimensional representation of the real-world object.
