    Abstract: Methods and systems disclosed provide improved depth sensing for an imaging device. In some aspects, a plurality of transmitters including a first transmitter are configured to generate a structured light pattern with a first depth of field at a first resolution and a second structured light pattern with a second depth of field at the first resolution, wherein the second depth of field is wider than the first depth of field. A receiver, such as an imaging sensor, is configured to focus within the first depth of field to receive the first structured light pattern and capture a first image representing the first structured light pattern and to focus within the second depth of field to receive the second structured light pattern and capture a second image representing the second structured light pattern. An electronic hardware processor is configured to generate a depth map of the scene based on the first image and the second image.

    Abstract: In general, techniques are described that facilitate processing of a depth map image in mobile devices. A mobile device comprising a depth camera, a camera and a processor may be configured to perform various aspects of the techniques. The depth camera may be configured to capture a depth map image of a scene. The camera may include a linear polarization unit configured to linearly polarize light entering into the camera. The camera may be configured to rotate the linearly polarization unit during capture of the scene to generate a sequence of linearly polarized images of the scene having different polarization orientations. The processor may be configured to perform image registration with respect to the sequence of linearly polarized images to generate a sequence of aligned linearly polarized images, and generate an enhanced depth map image based on the depth map image and the sequence of aligned linearly polarized images.

    Abstract: Aspects of the present disclosure relate to systems and methods for structured light depth systems. An example active depth system may include a receiver to receive reflections of transmitted light and a transmitter including one or more light sources to transmit light in a spatial distribution. The spatial distribution of transmitted light may include a first region of a first plurality of light points and a second region of a second plurality of light points. A first density of the first plurality of light points is greater than a second density of the second plurality of light points when a first distance between a center of the spatial distribution and a center of the first region is less than a second distance between the center of the spatial distribution and the center of the second region.

    Abstract: Aspects of the present disclosure relate to active depth sensing. An example device may include a memory and a processor coupled to the memory. The processor may be configured to determine an amount of ambient light for a scene to be captured by a structured light receiver and adjust an exposure time for frame capture of a sensor of the structured light receiver based on the determined amount of ambient light. The exposure time of the sensor of the structured light receiver is inversely related to the determined amount of ambient light. The processor further may be configured to receive a plurality of captured frames from the structured light receiver based on the adjusted exposure time and generate an aggregated frame, including aggregating values across the plurality of captured frames.
