Patent number: 11972586Abstract: A method to dynamically and adaptively sample the depths of a scene using the principle of triangulation light curtains is described. The approach directly detects the presence or absence of obstacles (or scene points) at specified 3D lines in a scene by sampling the scene. The scene can be sampled sparsely, non-uniformly, or densely at specified regions. The depth sampling can be varied in real-time, enabling quick object discovery or detailed exploration of areas of interest. Once an object is discovered in the scene, adaptive light curtains comprising dense sampling of a region of the scene containing the object, can be used to better define the position, shape and size of the discovered object.Type: GrantFiled: September 25, 2019Date of Patent: April 30, 2024Assignee: Carnegie Mellon UniversityInventors: Srinivasa Narasimhan, Joseph Bartels, William L Whittaker, Jian Wang
