Latest Patents

One of his latest patents is titled "Depth sensing with depth-adaptive illumination." This adaptive depth sensing system (ADSS) illuminates a scene with a pattern constructed based on an analysis of at least one prior-generated depth map. In one implementation, the pattern is a composite pattern that includes two or more component patterns associated with different depth regions in the depth map. The composite pattern may also include different illumination intensities associated with the different depth regions. By using this composite pattern, the ADSS can illuminate different objects in a scene with different component patterns and different illumination intensities, where those objects are located at different depths in the scene. This process can reduce the occurrence of defocus blur, underexposure, and overexposure in the image information.

Another notable patent is "Absolute phase measurement with secondary pattern-embedded fringe." In this innovation, multiple images of a scene are captured while a phase-shifted fringe embedded with a secondary pattern is projected onto the scene. A wrapped phase map is generated based on the captured images, and a continuous region mask is determined to segment the wrapped phase map into multiple continuous regions. A period disparity of the fringe is determined for each region based at least in part on the embedded secondary pattern. The regional period disparities are applied to a spatially unwrapped phase map to produce an absolute phase map and finally a depth map.
