Abstract: Techniques for correcting an overlay misalignment between an external camera image and a system camera image are disclosed. A first system camera image and a first external camera image are acquired. A first visual alignment is performed between those two images to produce an overlaid image. Some of the content in the overlaid image is surrounded by a bounding element. A position of the bounding element is modified based on movements of the system camera and/or the external camera. In response to performing a second visual alignment using new images, an update vector is computed. Relative movement between the two cameras is determined. Based on the movement and based on the update vector, the bounding element is progressively transitioned to a corrected position in the overlaid image. A speed by which the bounding element is progressively transitioned is proportional to the amount of movement.

Abstract: A system for efficiently generating SPAD imagery with persistence is configurable to capture an image frame, capture pose data associated with the capturing of the image frame, and access a persistence frame. The persistence frame includes a preceding composite image frame generated based on at least two preceding image frames. The at least two preceding image frames are associated with timepoints that precede a capture timepoint associated with the image frame. The system is configurable to generate a persistence term based on (i) the pose data, (ii) a similarity comparison based on the image frame and the persistence frame, or (iii) a signal strength associated with the image frame. The system is configurable to generate a composite image based on the image frame, the persistence frame, and the persistence term. The persistence term defines a contribution of the image frame and the persistence frame to the composite image.

Abstract: A system for structured light depth computation using single photon avalanche diodes (SPADs) is configurable to, over a frame capture time period, selectively activate the illuminator to perform interleaved structured light illumination operations. The interleaved structured light illumination operations comprise alternately emitting at least a first structured light pattern from the illuminator and emitting at least a second structured light pattern from the illuminator. The system is also configurable to, over the frame capture time period, perform a plurality of sequential shutter operations to configure each SPAD pixel of the SPAD array to enable photon detection. The plurality of sequential shutter operations generates, for each SPAD pixel of the SPAD array, a plurality of binary counts indicating whether a photon was detected during each of the plurality of sequential shutter operations.

Abstract: A system for generating high-resolution video from low-resolution images is configured to access a first video stream and a second video stream capturing an environment. The first video stream is captured by a first video capture device. The second video stream is captured by a second video capture device. Image frames of the first video stream are temporally synchronized with corresponding image frames of the second video stream. The system is also configured to generate a composite video stream with a higher resolution than the first or second video streams. Each composite image frame of the composite video stream is generated using a respective image frame of the first video stream and a temporally synchronized corresponding image frame of the second video stream as input.

Abstract: A system for HDR image capture is configurable to perform a split long exposure operation by applying a first set of long exposure shutter operations to configure each sensor pixel of the image sensor array to enable photon detection and applying a second set of long exposure shutter operations to configure each sensor pixel to enable photon detection. A time period intervenes between the first and second sets of long exposure shutter. The system is configurable to perform a short exposure operation by applying a set of short exposure shutter operations to configure each sensor pixel to enable photon detection. The short exposure operation occurs during the time period that intervenes between the first and second sets of long exposure shutter operations. The system is also configurable to generate an image based on the split long exposure operation and the short exposure operation.

Abstract: Examples are disclosed that relate to blending different types of images captured by different types of cameras employing different sensing modalities based on a dynamic weighting. The dynamic weighting is calculated based on a dynamic quality proxy that serves as an approximation of image quality that may change from image to image. In one example, a first image of a scene is received from a first camera. A dynamic quality proxy is received. A second image of the scene is received from a second camera with a different sensing modality than the first camera. A composite image blended from the first and second images in proportion to a dynamic weighting that is based on the dynamic quality proxy is output.

Abstract: A system for facilitating intensity image capture and time of flight capture. The system includes a single photon avalanche diode (SPAD) array comprising a plurality of SPAD pixels, one or more processors, and one or more hardware storage devices storing instructions that are executable by the one or more processors to configure the system to facilitate intensity image capture and time of flight capture by configuring the system to perform interleaved intensity image capture and time of flight capture operations using the SPAD array.

Abstract: A system for dense depth computation aided by sparse feature matching generates a first image using a first camera, a second image using a second camera, and a third image using a third camera. The system generates a sparse disparity map using the first image and the third image by (1) identifying a set of feature points within the first image and a set of corresponding feature points within the third image, and (2) identifying feature disparity values based on the set of feature points and the set of corresponding feature points. The system also applies the first image, the second image, and the sparse disparity map as inputs for generating a dense disparity map.

Abstract: A method for estimating human body temperature includes receiving, via a thermal camera, a thermal image captured of a real-world environment, the thermal image including thermal intensity values for each of a plurality of pixels of the thermal image. A position of a human face is identified within the thermal image, the human face corresponding to a human subject. An indication of a distance between the human subject and the thermal camera is received. Based on the distance, a distance correction factor is applied to one or more thermal intensity values of one or more pixels corresponding to the human face to give one or more distance-corrected thermal intensity values. Based on the one or more distance-corrected thermal intensity values an indication of a body temperature of the human subject is reported.
