  • Patent number: 11227194
    Abstract: The disclosure describes various embodiments of validating data synchronization between an active sensor and a passive sensor. According to an exemplary method of validating sensor synchronization between an active sensor and a passive sensor, a synchronization device receives a first signal from the active sensor, the first signal indicating that the active sensor has transmitted laser points to a measure board. In response to the first signal, the synchronization device transmits a second signal to the passive sensor to trigger the passive sensor to capture an image of the measure board. A synchronization validation application can perform an analysis of the image of the measure board in view of timing of the first signal and second signal to determine whether the passive sensor and the active sensor are synchronized with each other.

  • Patent number: 11200732
    Abstract: Disclosed is a method to derive the absorption coefficient, transparency, and/or the scattering coefficient from the user-specified parameters including roughness, phase function, index of refraction (IOR), and color by performing the simulation once, and storing the results of the simulation in an easy to retrieve representation, such as a lookup table, or an analytic function. To create the analytic function, one or more analytic functions can be fitted to the results of the simulation for the multiple parameters including roughness, phase function, IOR, and color. The lookup table can be combined with the analytic representation. For example, the lookup table can be used to represent the color, roughness, and phase function, while the IOR can be represented by an analytic function. For example, when the IOR is above 2, the lookup table becomes three-dimensional and the IOR is calculated using the analytic function.

  • Patent number: 11082679
    Abstract: According some aspects, a secondary device may display secondary audiovisual content along with playback of a video on a primary device. For example, the secondary device may display an augmented reality application synchronized with the video. Aspects may predetermine a set of frame transition ranges for the video, where each respective frame transition is determined based on frames of the video that are determined to be substantially identical by a frame reference function and frames that are determined to be different. Two frames may be substantially identical even if they are different in the source video. This may be due to shortcomings in the frame reference function, or encoding/compression losses in transmission and playback of the video. Playback may be synchronized based on a first detected frame, but synchronization may be refined upon detecting a frame transition to a second frame that is no longer substantially identical to prior frames.

  • Patent number: 11070790
    Abstract: Techniques are described for three-dimensional (3D) image sensing based on passive optical techniques and dynamic calibration. For example, light reflected from one or more objects in a scene is received via a lens of a novel 3D imaging system to forms an image of the object(s) on an image sensor through a spatial filter. A distribution of mask elements are associated with corresponding signal pixel sets of the image sensor, and reference elements of the spatial filter are associated with corresponding reference pixel sets of the image sensor; such that portions of the image tend to be shadowed by the mask elements at the signal pixel sets, but not at the reference pixel sets. Object distances for the one or more objects in the scene can be computed as a function of signal brightness detected by the signal pixel sets and reference brightness detected by the reference pixel sets.
