Abstract: Systems and methods for video georegistration are provided. An example method includes receiving an input video including a plurality of video frames; calibrating a first set of video frames selected from the plurality of video frames to generate a first set of calibrated video frames using a calibration transform; and performing one or more reference georegistrations to a second set of video frames selected from the plurality of video frames to generate a video georegistration transform using the second set of video frames. The second set of video frames have fewer video frames than the first set of video frames. The method further includes generating an output video using the calibration transform and the video georegistration transform.

Abstract: Systems and methods for visual navigation are provided. An example method includes receiving a plurality of video frames from an image sensor disposed on an aircraft, and generating an image-based transform based on the plurality of video frames. In some examples, the image-based transform is associated with a movement of one or more image features and a movement of the image sensor. In some examples, the method further includes: determining an image-based motion associated with the aircraft based on the image-based transform, generating a georegistration transform based on at least one video frame of the plurality of video frames and a reference image, determining a georegistration-based geolocation associated with the aircraft based on the georegistration transform, and determining an aircraft geolocation by applying a non-linear Kalman filter to the image-based motion and the georegistration-based geolocation,

Abstract: In some examples, systems and methods for multiple-sensor object tracking are provided. For example, a method includes: receiving a first sensor feed and a second sensor feed from a plurality of sensors respectively. The first sensor feed includes a set of first images. The second sensor feed includes a set of second images. In some examples, the method further includes generating an image transformation based on at least one first image in the set of first images and at least one second image in the set of second images, applying the image transformation to the set of second images, aggregating the set of first images and the set of transformed second images to generate a set of aggregated images, and applying a multiple object tracking model to the set of aggregated images to identify a plurality of objects.

Abstract: Systems and methods for video georegistration are provided. An example method includes: receiving an input image; generating a plurality of templates from the input image; and generating a template queue based at least in part on the plurality of template scores. The plurality of templates are associated with a plurality of template scores. The template queue includes a set of selected templates. The method further includes receiving one or more reference images; determining a set of match scores for the set of selected templates by applying a matching algorithm to the set of selected templates and at least one reference image of the one or more reference images; evaluating the set of match scores to select a collection of templates, and generating an image transform based at least in part on the collection of templates. Each template of the collection of templates meets one or more selection criteria.
