Patent number: 10219688Abstract: The present disclosure describes systems and methods to select fovea containing optical coherence tomography (OCT) images. The systems and methods described herein receive a plurality of OCT images. The portion of the OCT images are selected for further processing, where a line tracing the border between the retina and non-retina tissue is generated. A difference of the line is generated. Candidate OCT images are then generated responsive to the generated difference line. The lowest point among each difference lines generated for each of the OCT images is identified, and the OCT image to which the lowest point corresponds is identified as the fovea containing OCT image.Type: GrantFiled: October 18, 2016Date of Patent: March 5, 2019Assignee: The Charles Stark Draper Laboratory, Inc.Inventors: Nathan Lowry, Peter Lommel, Lei Hamilton, Rami Mangoubi

Patent number: 10062162Abstract: The present disclosure describes a system and method to segment optical coherence tomography (OCT) images. The present system uses a hybrid method that employs both Bayesian level sets (BLS) and graph-based segmentation algorithms. The system first identifies retinal tissue within an OCT image using the BLS algorithms. The identified retinal tissue is then further segmented using the graph-based segmentation algorithms.Type: GrantFiled: October 18, 2016Date of Patent: August 28, 2018Assignee: THE CHARLES STARK DRAPER LABORATORY, INC.Inventors: Nathan Lowry, Peter Lommel, Rami Mangoubi, Richard Wood, Lei Hamilton, John Irvine, Stephen Duncan

Publication number: 20180087907Abstract: In an embodiment, a localization module can provide coordinates of the vehicle relative to the Earth and relative to the drivable surface, both of which are precise enough to allow for self-driving, and further can compensate for a temporary lapse in reliable GPS service by continuing to track the car's position by tracking its movement with inertial sensors (e.g., accelerometers and gyroscopes) and RADAR data. The localization module bases its output on a geolocation relative to the Earth and sensor measurements of the drivable surface and its surroundings to determine where the car is in relation to the Earth and the drivable surface.Type: ApplicationFiled: September 29, 2016Publication date: March 29, 2018Inventors: Paul DeBitetto, Matthew Graham, Troy Jones, Peter Lommel, Jon Demerly

Patent number: 8868323Abstract: A method for collaborative navigation between two or more platforms is provided. The method comprises establishing a communication link between a first platform and a second platform, making a sensor measurement from the first platform, updating state and covariance elements of the first platform, and transmitting the updated state and covariance elements from the first platform to the second platform. A conditional update is performed on the second platform to compute a new estimate of state and covariance elements on the second platform, which takes into account the measurement from the first platform. The method further comprises making a sensor measurement from the second platform, updating state and covariance elements of the second platform, and transmitting the updated state and covariance elements from the second platform to the first platform.Type: GrantFiled: March 22, 2011Date of Patent: October 21, 2014Assignee: Honeywell International Inc.Inventors: Peter Lommel, Benjamin Mohr, Yunqian Ma

Patent number: 7970507Abstract: This invention provides a system and method for autonomously tracking a moving target from unmanned aerial vehicles (UAVs) with a variety of airframe and sensor payload capabilities so that the target remains within the vehicle's sensor field of view regardless of the specific target motion patterns. The invention uses information about target location, UAV platform type and states, sensor payload capability, and ratio of target-to-UAV speeds to select from a suite of sub-algorithms, each of which generates desired platform positions (in form of waypoints) and/or sensor orientation commands to keep the target in view.Type: GrantFiled: January 23, 2008Date of Patent: June 28, 2011Assignee: Honeywell International Inc.Inventors: Kingsley O C Fregene, Peter Lommel

Publication number: 20060058931Abstract: Collision avoidance systems and methods are implemented on unmanned mobile vehicles to supplement map-based trajectories generated by the vehicles' navigation systems. These systems include radar, which detect obstacles in the path of the unmanned mobile vehicles, and collision avoidance modules, which enable the vehicles to avoid unexpected obstacles by adjusting their trajectories and velocities based on feedback received from the radar. In general, when an obstacle is detected by the radar, the collision avoidance module modifies the commanded velocity of an unmanned mobile vehicle by subtracting from the nominal commanded velocity the component that is in the direction of the obstacle. The magnitude of the velocity modification typically increases as the distance between the mobile vehicle and the obstacle decreases.Type: ApplicationFiled: September 15, 2004Publication date: March 16, 2006Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Kartik Ariyur, Dale Enns, Peter Lommel
