The method includes receiving sparse sensor data from a sensor system of the robot, synchronizing the received sensor data with a change in robot pose, accumulating the synchronized sensor data over time, and determining a robot localization quality. When the accumulated sensor data exceeds a threshold accumulation and the robot localization quality is greater than a threshold localization quality, the method includes updating particles with accumulated synchronized sensor data. The method includes determining a weight for each updated particle of the particle model and setting a robot pose belief to the robot pose of the particle having the highest weight when a mean weight of the particles is greater than a threshold particle weight.Type: GrantFiled: March 8, 2013Date of Patent: April 28, 2015Assignee: iRobot CorporationInventor: Mark Schnittman

Patent number: 9018577Abstract: A vehicular imaging system comprises a single imaging sensor having a plurality of photosensor elements. The imaging sensor captures image data of a scene exterior of the vehicle within its field of view. Image data captured by the imaging sensor is provided to a control. The control also receives via a communication bus at least one of vehicle pitch information, vehicle yaw information and vehicle steering information. The control detects two substantially straight and converging road features along the road the vehicle is travelling and determines a point of intersection where they would converge using, at least in part, the received vehicle information and the control automatically corrects for misalignment of the imaging sensor mounted at the vehicle.Type: GrantFiled: February 25, 2013Date of Patent: April 28, 2015Assignee: Magna Electronics Inc.Inventors: Yuesheng Lu, Michael J. Higgins-Luthman, Antony V. Jeyaraj, Manoj R. Phirke

Patent number: 9014903Abstract: An autonomous vehicle configured to determine the heading of an object-of-interest based on a point cloud. An example computer-implemented method involves: (a) receiving spatial-point data indicating a set of spatial points, each spatial point representing a point in three dimensions, where the set of spatial points corresponds to an object-of-interest; (b) determining, for each spatial point, an associated projected point, each projected point representing a point in two dimensions; (c) determining a set of line segments based on the determined projected points, where each respective line segment connects at least two determined projected points; (d) determining an orientation of at least one determined line segment from the set of line segments; and (e) determining a heading of the object-of-interest based on at least the determined orientation.Type: GrantFiled: May 22, 2012Date of Patent: April 21, 2015Assignee: Google Inc.Inventors: Jiajun Zhu, Dmitri A.

Publication number: 20150104074Abstract: Aspects of depth map generation and post capture focusing and re-focusing are described. According to one embodiment, a depth map is generated. The depth map may include a mapping among relative depth values in a field of view of an image based on a difference between pixels of a first image and pixels of a second image. An edge map may also be generated by identifying edges in at least one of the first image or the second image. Using the depth map and the edge map, the relative depth values in the depth map may be smoothed using the edge map. In this manner, certain discontinuities in depth values may be smoothed within edge-bounded regions defined by the edge map. The depth map may be used for focusing and re-focusing, for example, or for object extraction, scene understanding, or gesture recognition, among other imaging processes.Type: ApplicationFiled: October 29, 2013Publication date: April 16, 2015Applicant: Broadcom CorporationInventors: Gary Lee Vondran, JR., Charles Dunlop Macfarlane
