Abstract

A method for capturing geometric features of real-world scenes relies on a simple modification of the capture setup: A multiflash camera is used with flashes strategically positioned to cast shadows along depth discontinuities in the scene, allowing efficient and accurate shape extraction. The entire hardware and software setup can be conceivably packaged into a self-contained device, no larger than existing digital cameras.
