Patent number: 10726616Abstract: An image processing system configured to process perceived images of an environment includes a central processing unit (CPU) including a memory storage device having stored thereon a computer model of the environment, at least one sensor configured and disposed to capture a perceived environment including at least one of visual images of the environment and range data to objects in the environment, and a rendering unit (RU) configured and disposed to render the computer model of the environment forming a rendered model of the environment. The image processing system compares the rendered model of the environment to the perceived environment to update the computer model of the environment.Type: GrantFiled: November 12, 2019Date of Patent: July 28, 2020Assignee: ROSEMOUNT AEROSPACE INC.Inventors: Julian C.

Patent number: 10676213Abstract: According to an aspect of the invention, a method of optimal safe landing area determination for an aircraft includes accessing a probabilistic safe landing area map that includes a plurality of probabilistic indicators of safe landing areas for the aircraft. A processing subsystem that includes one or more processing resources generates a list of candidate safe landing areas based on the probabilistic safe landing area map and one or more constraints. At least two of the candidate safe landing areas are provided to a path planner. The list of candidate safe landing areas is ranked based on results from the path planner indicating an estimated cost to reach each of the candidate safe landing areas. Based on the ranking, an indicator of an optimal safe landing area is output as a desired landing location for the aircraft.Type: GrantFiled: October 16, 2015Date of Patent: June 9, 2020Assignee: SIKORSKY AIRCRAFT CORPORATIONInventors: Xuchu Ding, Jason C. Derenick, Brendan J. Englot, Igor Cherepinsky, Harshad S. Sane, Christopher Stathis

Patent number: 10266280Abstract: A method of performing a cooperative safe landing area determination includes receiving perception sensor data indicative of conditions at a plurality of potential landing areas. A processing subsystem of a vehicle updates a local safe landing area map based on the perception sensor data. The local safe landing area map defines safe landing area classifications and classification confidences associated with the potential landing areas. One or more remotely-generated safe landing area maps are received from one or more remote data sources. The one or more remotely-generated safe landing area maps correspond to one or more additional potential landing areas and non-landing areas. The local safe landing area map and the remotely-generated safe landing area maps are aggregated to form a fused safe landing area map. The fused safe landing area map is used to make a final safe landing area determination.Type: GrantFiled: June 18, 2015Date of Patent: April 23, 2019Assignee: SIKORSKY AIRCRAFT CORPORATIONInventors: Jason C.
