Bio: Dr. Lawrence Ray received his doctorate in mathematics from the University of Rochester in algebraic topology. After graduation, he pursued activities in support of the US Navy in terms of budgeting of major system acquisition and later in anti-submarine warfare analyses. He then joined the Eastman Kodak Research Labs, where he was Kodak’s scientist in residence at the National Center for Supercomputing Applications at the University of Illinois. After returning to Rochester, he worked on an array projects, including the development of a 3D camera system. He is now with Carestream Health as the Chief Scientist in Research and Innovation. Dr. Ray is an inventor on nearly 90 US Patents.

Abstract: A fundamental aspect of establishing a depth map using stereo cameras is establishing a pixel correspondence across images. A common method to accomplish this is by using a structured light pattern. A number of problems arise with many strategies for applying structured light. The approach described in uses a variation of De Bruijn sequences and an optimization algorithm to overcome some implementation problems.
