  • Patent number: 11448757
    Abstract: In a distance measuring device that measures a distance to an object using a round-trip time of light, a solid-state image sensor includes a plurality of pixel groups capable of being exposed independently, and causes each of the plurality of pixel groups to receive, at a different exposure time, reflected light from the object that is originally pulsed radiation light from a light emitter.

  • Patent number: 11423605
    Abstract: Embodiments of the present specification provide systems and methods to provide a 3D experience in a 2D game, while using the same underlying gaming engine. A 2D game space representing an axonometric projection is overlaid with 3D visuals, in a way that the original 2D simulation can still be used to run the game. In embodiments, a set of custom tools are used to map the 2D ground plane to a 3D ground plane. The 2D objects are then mapped into 3D objects. The 3D game environment corresponding to the original 2D game layout is created at backend by one or more individuals, using custom graphic tools. Dynamic player remap in 3D is generated in real time while the player engages with the 2D game. Therefore, while a player is playing the 2D game, a dynamic equivalent of the game in 3D is rendered.

  • Patent number: 11398094
    Abstract: Motion of actors within a scene may be detected based on imaging data, using machine learning tools operating on cameras that captured the imaging data. The machine learning tools process images to perform a number of tasks, including detecting heads of actors, and sets of pixels corresponding to the actors, before constructing line segments from the heads of the actors to floor surfaces on which the actors stand or walk. The line segments are aligned along lines extending from locations of heads within an image to a vanishing point of a camera that captured the image. Trajectories of actors and visual data are transferred from the cameras to a central server, which links trajectories captured by multiple cameras and locates detected actors throughout the scene, even when the actors are not detected within a field of view of at least one camera.

  • Patent number: 11257237
    Abstract: Disclosed herein are optimized techniques for controlling the exposure time or illumination intensity of a depth sensor. Invalid-depth pixels are identified within a first depth map of an environment. For each invalid-depth pixel, a corresponding image pixel is identified in a depth image that was used to generate the first depth map. Multiple brightness intensities are identified from the depth image. Each brightness intensity is categorized as corresponding to either an overexposed or underexposed image pixel. An increased exposure time or illumination intensity or, alternatively, a decreased exposure time or illumination intensity is then used to capture another depth image of the environment. After a second depth map is generated based on the new depth image, portion(s) of the second depth map are selectively merged with the first depth map by replacing the invalid-depth pixels of the first depth map with corresponding valid-depth pixels of the second depth map.

  • Patent number: 11244432
    Abstract: Image processing methods and systems apply filtering operations to images, wherein the filtering operations use filter costs which are based on image gradients in the images. In this way, image data is filtered for image regions in dependence upon the image gradients for the image regions. This may be useful for different scenarios such as when combining images to form a High Dynamic Range (HDR) image. The filtering operations may be used as part of a connectivity unit which determines connected image regions, and/or the filtering operations may be used as part of a blending unit which blends two or more images together to form a blended image.

  • Patent number: 11226198
    Abstract: A three-dimensional scanning system includes a projection light source, an image capturing apparatus, and a signal processing apparatus. The projection light source is configured to project a two-dimensional light to a target, where the two-dimensional light has a spatial frequency. The image capturing apparatus captures an image of the target illuminated with the two-dimensional light. The signal processing apparatus is coupled to the projection light source and the image capturing apparatus, to analyze a definition of the image of the two-dimensional light, where if the definition of the image of the two-dimensional light is lower than a requirement standard, the spatial frequency of the two-dimensional light is reduced.

  • Patent number: 11206384
    Abstract: Depth information can be used to assist with image processing functionality, such as image stabilization and blur reduction. In at least some embodiments, depth information obtained from stereo imaging or distance sensing, for example, can be used to determine a foreground object and background object(s) for an image or frame of video. The foreground object then can be located in later frames of video or subsequent images. Small offsets of the foreground object can be determined, and the offset accounted for by adjusting the subsequent frames or images. Such an approach provides image stabilization for at least a foreground object, while providing simplified processing and reduce power consumption. Similarly processes can be used to reduce blur for an identified foreground object in a series of images, where the blur of the identified object is analyzed.

  • Patent number: 11191430
    Abstract: A Bowman's Refractive Index (BRI) for quantification of microdistortions in Bowman's Layer (BL) after Small Incision Lenticule Extraction (SMILE) is defined for a patient. BRI is summation of one or more areas of the OCT image of anterior edge of Bowman's layer, quantifies the smoothness of the Bowman's layer. The anterior edge of Bowman's layer is segmented into pixels. After segmentation, a 3rd order polynomial is curve fit to the segmented pixels of the edge of Bowman's layer. BRI is calculated by segmentation of the 3-Dimensional (3-D) OCT image. BRI acts as a marker for mechanical stability and is useful for diagnosis of disease and prognosis of treatments in human.

  • Patent number: 11184517
    Abstract: A system of cameras can be used to generate a complete field of view within an edge network. For example, one camera can have a field of view where part of the view is obstructed by an object and/or by the camera's orientation. Yet another camera that is a part of the edge network can supplement the view of the first camera by providing an alternate view. The two views can be stitched together by a coordinate system such that a complete field of view can be utilized by both cameras. Additionally, where a field of view is not available by any stationary camera, the system can dispatch a mobile camera to help supplement the views.

  • Patent number: 11176703
    Abstract: A system uses a fleet of AVs to assess visibility of target objects. Each AV has a camera for capturing images of target objects. AVs provide the captured images, or visibility data derived from the captured images, to a remote system, which aggregates visibility data describing images captured across the fleet of AVs. The AVs also provide condition data describing conditions under which the images were captured, and the remote system aggregates the condition data. The remote system processes the aggregated visibility data and condition data to determine conditions under which a target object does not meet a visibility threshold.
