    Abstract: 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.

    Abstract: An electronic device is described. The electronic device includes a camera configured to capture an image of a scene. The electronic device also includes an image segmentation mapper configured to perform segmentation of the image based on image content to generate a plurality of image segments, each of the plurality of image segments associated with spatial coordinates indicative of a location of each segment in the scene. The electronic device further includes a memory configured to store the image and the spatial coordinates. The electronic device additionally includes a LIDAR (light+radar) unit, the LIDAR unit steerable to selectively obtain depth values corresponding to at least a subset of the spatial coordinates. The electronic device further includes a depth mapper configured to generate a depth map of the scene based on the depth values and the spatial coordinates.

    Abstract: Methods and apparatus for determining a depth of an object within a scene are provided. Image data of a scene can be captured using a lens configured to project an image of the scene onto an image sensor. The lens has a known focal length and is movable between at least a first lens position and a second lens position. A first image of the scene is captured with the lens at a first lens position, and a second image of the scene is captured with the lens at a second, different position. By measuring a first dimension of the object using the first image and a second dimension of the object using the second image, a depth of the object may be determined based upon a ratio of the first and second dimensions, the focal length of the lens, and a distance between the first and second lens positions.

    Abstract: Innovations include a sensing device having a sensor array comprising a plurality of sensors, each sensor having a length dimension and a width dimension and configured to generate a signal responsive to radiation incident on the sensor, and a filter array comprising a plurality of filters, the filter array disposed to filter light before it is incident on the sensor array, the filter array arranged relative to the sensor array so each of the plurality of sensors receives radiation propagating through at least one corresponding filter. Each filter has a length dimension and a width dimension, and a ratio of the length dimension of a filter to the length dimension of a corresponding sensor, a ratio of the width dimension of a filter to the width dimension of a corresponding sensor, or both, is a non-integer greater than 1.
