Abstract: A system and method for head tracking for a head worn display (HWD) includes head-frame and platform-frame IMUs providing high-rate pose data of the wearer's head and a mobile platform. An optical tracker estimates an optical pose of a camera oriented at fiducials based on a comparison of 2D image data captured by the camera (and portraying the fiducials within the image) and the known location of each fiducial in a 3D marker frame. The pIMU also provides low-rate, high-integrity georeferenced pose data of the mobile platform (e.g., in an earth frame). The head tracker provides low-rate, high-integrity absolute head pose solutions (e.g., user head pose in the earth frame) based on the georeferenced pose data and current high-rate head/platform pose data, updating the absolute pose solutions with high-rate updates based on combined extended Kalman filter propagation of the high-rate head and platform pose data with refined optical pose data.

Abstract: A system includes at least one camera implemented in an aircraft, the at least one camera configured to capture images external to the aircraft. The system further includes at least one processor implemented in the aircraft, one or more of the at least one processor communicatively coupled to the at least one camera, the at least one processor configured to: receive the images from the at least one camera; identify visual references in at least one of the images; and output an annunciation instruction configured to cause an annunciation to a pilot that the visual references have been identified by the at least one processor.

Abstract: A system and method for conformal alignment of an aircraft-based head worn display (HWD) system defines far-field features in view of the HWD display, each far-field feature having a 3D truth position in a navigational reference frame. The aircraft GPS/IRS determines pointing vectors to each feature in the aircraft reference frame. The HWD user estimates a nominal head pose for orienting the far-field features in the HWD display, and the HWD system renders the far-field features based on the nominal head pose and pointing vectors. The rendered far-field features are aligned to their real-world 3D truth positions (either manually or with the assistance of witness cameras) and a latched pose of the HWD headtracker system determined based on a successful alignment within accuracy bounds. Based on the latched headtracker pose, the HWD headtracker alignment and the alignment of the HWD display reference frame to the aircraft reference frame are updated.

Abstract: Systems, apparatus, methods, and articles of manufacture provide for image analysis using localized information. In one embodiment, an object (e.g., content of a building or other type of property) may be classified by determining the type of object and determining classification information associated with previously classified objects of the same type and associated with the same geographical area.
