  • Patent number: 10893227
    Abstract: Using the same image sensor to capture a two-dimensional (2D) image and three-dimensional (3D) depth measurements for a 3D object. A laser point-scans the surface of the object with light spots, which are detected by a pixel array in the image sensor to generate the 3D depth profile of the object using triangulation. Each row of pixels in the pixel array forms an epipolar line of the corresponding laser scan line. Timestamping provides a correspondence between the pixel location of a captured light spot and the respective scan angle of the laser to remove any ambiguity in triangulation. An Analog-to-Digital Converter (ADC) in the image sensor operates as a Time-to-Digital (TDC) converter to generate timestamps. A timestamp calibration circuit is provided on-board to record the propagation delay of each column of pixels in the pixel array and to provide necessary corrections to the timestamp values generated during 3D depth measurements.

  • Patent number: 10880573
    Abstract: Dynamic motion vector referencing is used to predict motion within video blocks. A motion trajectory is determined for a current frame including a video block to encode or decode based on a reference motion vector used for encoding or decoding one or more reference frames of the current frame. One or more temporal motion vector candidates are then determined for predicting motion within the video block based on the motion trajectory. A motion vector is selected from a motion vector candidate list including the one or more temporal motion vector candidates and used to generate a prediction block. The prediction block is then used to encode or decode the video block. The motion trajectory is based on an order of video frames indicated by frame offset values encoded to a bitstream. The motion vector candidate list may include one or more spatial motion vector candidates.

  • Patent number: 10854073
    Abstract: A method of recording and reporting traffic violations using a central recording unit that has at least one video camera and possibly additional still and video cameras. Additionally, there may be other cameras that interface with the central recording unit. The central recording unit is mounted to a vehicle in which it is used and may be connected to a separate gateway device that can transmit data to a violation recording center that will process data taken by the central recording unit. The violation recording center will evaluate whether data taken regarding other motorists warrants sending a fine to a non-compliant driver who is violating traffic laws. The method of this system provides for recording data regarding the non-compliant driver for a time before activation to a time after activation so that a full data bundle may be reviewed to determine whether a violation of traffic laws has occurred.
