Depth Image Generation Utilizing Pseudoframes Each Comprising Multiple Phase Images

Abstract

In one embodiment, an image processor is configured to obtain phase images, and to group the phase images into pseudoframes with each of at least a subset of the pseudoframes comprising multiple ones of the phase images and having as a first phase image thereof one of the phase images that is not a first phase image of an associated depth frame. A velocity field is estimated by comparing corresponding phase images in respective ones of the pseudoframes. Phase images of one or more pseudoframes are modified based at least in part on the estimated velocity field, and one or more depth images are generated based at least in part on the modified phase images. By way of example, different groupings of the phase images into pseudoframes may be used for each obtained phase image, allowing depth images to be generated at much higher rates than would otherwise be possible.
