  • Planar surface detection
    Patent number: 11302023
    Abstract: In one implementation, a method of generating a horizontal plane hypothesis includes obtaining a point cloud of a scene including a plurality of points in a gravity-aligned coordinate system. The method includes generating, based on the plurality of points, a height histogram indicative of a plurality of non-overlapping height ranges in the gravity-aligned coordinate system and a respective plurality of weights. The method includes generating one or more horizontal plane hypotheses based on the height histogram.
    Type: Grant

  • Planar region boundaries based on intersection
    Patent number: 11030474
    Abstract: Implementations disclosed herein more accurately and efficiently identify planar region boundaries corresponding to surfaces in a physical environment based on identifying intersections. In some implementations a detected planar region is altered, e.g., trimmed or extended, based on detecting an intersection of the planar region with an expansion of another planar region. In other implementations, a detected planar region is altered, e.g., trimmed or extended, based on detecting an intersection of the planar region with a detected edge line.
