  • Patent number: 10885718
    Abstract: An exemplary virtual reality system determines a first confidence metric representing an objective degree to which a pre-modeled object is recognized within a first captured image depicting a scene from a first vantage point. The virtual reality system also determines a second confidence metric representing an objective degree to which the pre-modeled object is recognized within a second captured image depicting the scene from a second vantage point distinct from the first vantage point. The virtual reality system then generates a rendered image that includes a depiction of the pre-modeled object from a third vantage point distinct from the first and second vantage points. The depiction of the pre-modeled object is generated based on data from the first and second captured images, the data prioritized for the depiction of the pre-modeled object according to relative magnitudes of the first and second confidence metrics. Corresponding methods and systems are also disclosed.

  • Publication number: 20200083660
    Abstract: A wavelength selection method for a tunable laser includes: obtaining a target wavelength; and calculating target resistance values of two thermistors, respectively, corresponding to the target wavelength. Each of the two thermistors is used to monitor the temperature of a corresponding one of two wavelength selection components. Each of the target resistance values is calculated according to a relationship between a wavelength drift and a resistance change of the corresponding thermistor and according to an initial wavelength and an initial resistance value of the corresponding thermistor corresponding to the initial wavelength. The method further includes: heating the two wavelength selection components to control their temperatures until real-time resistance values of the two thermistors reach the target resistance values, respectively; and stabilizing the real-time resistance values at the target resistance values and outputting a laser beam having the target wavelength.

  • Patent number: 10306212
    Abstract: An exemplary volumetric frame capture controller (“controller”) transmits first and second commands to first and second three-dimensional (“3D”) capture devices disposed, respectively, at first and second positions with respect to a real-world scene. The first and second commands are to capture, respectively, first and second 3D sub-frames representative of the real-world scene from first and second vantage points associated with the first and second positions. Based on the first and second commands, the controller receives the first and second 3D sub-frames and, in response, determines that a first timestamp associated with a capture of the first 3D sub-frame is less than a predefined time threshold from a second timestamp associated with a capture of the second 3D sub-frame. In response to this determination, the controller provides the first and second 3D sub-frames for use in forming a volumetric frame of the real-world scene. Corresponding methods and systems are also disclosed.
