Abstract: Systems and methods for image matching are provided. An example method includes receiving an incoming image of a first imaging modality; receiving a reference image of a second imaging modality, the second imaging modality being different from the first imaging modality; generating a reference view of the reference image based on one or more priors associated with the incoming image; detecting a plurality of features corresponding to a plurality of feature points in the incoming image using a first algorithm that generates relatively even distribution of the plurality of feature points; generating a plurality of feature descriptors corresponding to the plurality of features, at least one of the plurality of feature descriptors being associated with at least one of a plurality of orientation bins.

Abstract: Systems and methods for georegistration are provided. An example method includes receiving a video stream including a plurality of video frames collected by an image sensor, presenting the video stream via a video player, and receiving user input associated with a first video frame of the plurality of video frames and a reference image. In some examples, the first video frame includes incomplete telemetry data. In some examples, the method further includes determining one or more coordinates associated with the first video frame based on user input associated with the first video frame and the reference image, determining the incomplete telemetry data associated with the first video frame based on the one or more determined coordinates, and generating a georegistration transform based on the determined telemetry data and the reference image.

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.

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: A plurality of images is obtained, whether as separate images or part of a video. The plurality of images is used to generate a three-dimensional (3D) model of the imagery. The 3D model is registered to a geographic coordinate system as a first registered 3D model. The first registered 3D model is merged with a second registered 3D model to generate a merged 3D model. A request including a value corresponding to a location within the geographic coordinate system that includes at least a portion of the merged 3D model is received from a client device. A message identifying at least a subset of points in the portion of the merged 3D model is sent to the client device, each point in the subset having a three-dimensional coordinate.

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 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.
