  • Publication number: 20240410726
    Abstract: In various examples, disclosed techniques introduce a time-window based sensor measurement scheduling engine that determines an ordering of measurements received from multiple sensors. The measurements may be sorted by detection time and submitted in sorted order to a sensor fusion system. Upon receiving measurements from sensors, the scheduling engine determines a current time window between a most recently-submitted measurement and a most recent camera measurement. Any measurements from other sensors, such as RADAR, that are less than a threshold amount of time ahead of or behind the current time window can be extrapolated to a time in the current time window for comparison with camera measurements. The scheduling engine then sorts the selected measurements based on their timestamps in the current time window, and submits the selected measurements to the fusion system in sorted order. The system may then perform downstream operations, such as object tracking, using the sorted measurements.

  • Publication number: 20240265555
    Abstract: Systems and methods are disclosed that use a geometric approach to detect objects on a road surface. A set of points within a region of interest between a first frame and a second frame are captured and tracked to determine a difference in location between the set of points in two frames. The first frame may be aligned with the second frame and the first pixel values of the first frame may be compared with the second pixel values of the second frame to generate a disparity image including third pixels. Subsets of the third pixels that have an disparity image value about a first threshold may be combined, and the third pixels may be scored and associated with disparity values for each pixel of the one or more subsets of the third pixels. A bounding shape may be generated based on the scoring that corresponds to the object.

  • Patent number: 11961243
    Abstract: A geometric approach may be used to detect objects on a road surface. A set of points within a region of interest between a first frame and a second frame are captured and tracked to determine a difference in location between the set of points in two frames. The first frame may be aligned with the second frame and the first pixel values of the first frame may be compared with the second pixel values of the second frame to generate a disparity image including third pixels. One or more subsets of the third pixels that have a value above a first threshold may be combined, and the third pixels may be scored and associated with disparity values for each pixel of the one or more subsets of the third pixels. A bounding shape may be generated based on the scoring.
