  • Patent number: 12254646
    Abstract: A system for refining a six degrees of freedom pose estimate of a target object based on a one-dimensional measurement includes a camera and a range-sensing device. The range-sensing device is configured to determine an actual distance measured between the range-sensing device and an actual point of intersection. The range-sensing device projects a line-of-sight that intersects with the target object at the actual point of intersection. The system also includes one or more processors in electronic communication with the camera and the range-sensing device and a memory coupled to the processors. The memory stores data into one or more databases and program code that, when executed by the processors, causes the system to predict the six degrees of freedom pose estimate of the target object. The system also determines a revised six degrees of freedom pose estimate of the target object based on at least an absolute error.

  • Publication number: 20250022157
    Abstract: Disclosed herein are methods, systems, and aircraft for performing image analysis for aiding refueling operations. A tanker aircraft includes a camera system configured to generate a two-dimensional (2D) image of a receiving aircraft and a depth image of the receiving aircraft, a processor, and non-transitory computer readable storage media storing code. The code is executable by the processor to perform operations including detecting the receiving aircraft within the 2D image based on 2D image values, determining 2D keypoints of the receiving aircraft located within the 2D image based on the depth image, the 2D image values, and a previously determined keypoint model, determining a 6 degree-of-freedom (6DOF) pose using the 2D keypoints and corresponding three-dimensional (3D) keypoints, and outputting a position of at least a component of the receiving aircraft based on the 6DOF pose.

  • Patent number: 12139271
    Abstract: Aspects of the disclosure provide fuel receptacle and boom tip position and pose estimation for aerial refueling. A video frame is received and within the video frame, aircraft keypoints for an aircraft to be refueled are determined. Based on at least the aircraft keypoints, a position and pose of a fuel receptacle on the aircraft is determined. Within the video frame, a boom tip keypoint for a boom tip of an aerial refueling boom is also determined. Based on at least the boom tip keypoint, a position and pose of the boom tip is determined. Based on at least the position and pose of the fuel receptacle and the position and pose of the boom tip, the aerial refueling boom is controlled to engage the fuel receptacle. Some examples overlay projections of an aircraft model on displayed video for a human observer.

  • Patent number: 12066530
    Abstract: A method, apparatus and computer program product are provided to generate a model of one or more objects relative to a vehicle. In the context of a method, radar information is received in the form of in-phase quadrature (IQ) data and the IQ data is converted to one or more first range-doppler maps. The method further includes evaluating the one or more first range-doppler maps with a machine learning model to generate the model that captures the detection of the one or more objects relative to the vehicle. A corresponding apparatus and computer program product are also provided.

  • Patent number: 11734924
    Abstract: Described is a system for onboard, real-time, activity detection and classification. During operation, the system detects one or more objects in a scene using a mobile platform and tracks each of the objects as the objects move in the scene to generate tracks for each object. The tracks are transformed using a fuzzy-logic based mapping to semantics that define group activities of the one or more objects in the scene. Finally, a state machine is used to determine whether the defined group activities are normal or abnormal phases of a predetermined group operation.
