摘要： Systems and methods for correcting errors in a depth map generated by a structured light system are disclosed. In one aspect, a method includes dividing a depth map into segments and calculating a density distribution of the depth values for each segment. The method includes detecting error (or "outlier") values by determining the depth values that fall outside of a range of depth values, the range of depth values representative of the highest density depth values for a given segment. The method includes detecting error values in the depth map as a whole based on the density distribution values for each segment.

摘要： Systems, apparatus, and methods for generating a fused depth map from one or more individual depth maps, wherein the fused depth map is configured to provide robust depth estimation for points within the depth map. The methods, apparatus, or systems may comprise components that identify a field of view (FOV) of an imaging device configured to capture an image of the FOV and select a first depth sensing method. The system or method may sense a depth of the FOV with respect to the imaging device using the first selected depth sensing method and generate a first depth map of the FOV based on the sensed depth of the first selected depth sensing method. The system or method may also identify a region of one or more points of the first depth map having one or more inaccurate depth measurements and determine if additional depth sensing is needed.

摘要： An interactive display, including a cover glass having a front surface that includes a viewing area provides an input/output (I/O) interface for a user of an electronic device. An arrangement includes a processor, a light source, and a camera disposed outside the periphery of the viewing area coplanar with or behind the cover glass. The camera receives scattered light resulting from interaction, with an object, of light outputted from the interactive display, the outputted light being received by the cover glass from the object and directed toward the camera. The processor determines, from image data output by the camera, an azimuthal angle of the object with respect to an optical axis of the camera and/or a distance of the object from the camera.

摘要： Methods, systems, and apparatuses are provided to compensate for a misalignment of optical devices within an imaging system. For example, the methods receive image data captured by a first optical device having a first optical axis and a second optical device having a second optical axis. The methods also receive sensor data indicative of a deflection of a substrate that supports the first and second optical devices. The deflection can result from a misalignment of the first optical axis relative to the second optical axis. The methods generate a depth value based on the captured image data and the sensor data. The depth value can reflect a compensation for the misalignment of the first optical axis relative to the second optical axis.

摘要： 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.

摘要： 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.
