Accurate real-time occlusion for mixed reality
David R. Walton, Anthony J. Steed · 2017
Properly handling occlusion between real and virtual objects is an important property for any mixed reality (MR) system. Existing methods have typically required known geometry of the real objects in the scene, either specified manually, or reconstructed using a dense mapping algorithm. This limits the situations in which they can be applied. Modern RGBD cameras are cheap and widely available, but the depth information they provide is typically too noisy and incomplete to use directly to provide quality results.
