US Patent 11030474 Planar region boundaries based on intersection

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.
