Abstract: A method includes generating calibration data by geometrically calibrating first image data from a first camera unit relative to second image data from a second camera unit based on first descriptor data and second descriptor data. The first descriptor data is based on the first image data. The second descriptor data is based on the second image data. The calibration data is generated based on first position data corresponding to the first camera unit and second position data corresponding to the second camera unit. The method includes identifying, based on the calibration data, a target location relative to the first image data. The method further includes generating an output image that includes the first image data and an indication of where the target location is relative to a scene depicted in the first image data.

Abstract: An apparatus includes an interface configured to receive image data and position data from an aircraft. The image data is associated with a plurality of images of a scene including an object. The position data is associated with positions of a camera of the aircraft that captured the plurality of images. The apparatus further includes a processor configured to identify a first camera position corresponding to a first image of the plurality of images. The processor further configured to identify a first relative position of the object relative to the camera. The first relative position identified based on the first camera position, the first image data, and second image data corresponding to a second image of the plurality of images. The processor further configured to output an indication of a global position of the object based on the position data and the first relative position of the object.

Abstract: Optical sighting is performed using plural optical sighting apparatuses that each comprise: a camera unit and a viewing system for viewing images. Geometric calibration of the camera units with respect to the imaged scene is performed by detecting features within captured images, generating descriptors from respective patches of the image at the features; detecting corresponding descriptors from different images, and deriving the geometric calibration from the positions in the respective images of the corresponding descriptors. A target location in a designator image captured at an earlier image-capture time is designated and a corresponding location relative to the current image captured at the current time is identified from the geometric calibration. A viewing system indicates where the corresponding location lies relative to the current image.

Abstract: The absolute position of a target object point is determined using a series of images of the scene with overlapping fields of view captured by a camera in positions arranged in at least two dimensions across the scene and position data representing the absolute positions of the camera on capture of the respective images. The images are analyzed to identify sets of image points corresponding to common object points in the scene. A bundle adjustment is performed on the sets of image points that estimates parameters representing the positions of the object points relative to the positions of the camera associated with each image, but without using input orientation data representing the orientation of the camera. The absolute position of the target object point is derived on the basis of the results of the bundle adjustment and the absolute positions of the camera represented by the position data.

Abstract: Collaborative sighting is performed using plural optical sighting apparatuses that each comprise: a camera unit and a display device. Geometric calibration of the camera units with respect to the imaged scene is performed by detecting features within captured images, generating descriptors from respective patches of the image at the features; detecting corresponding descriptors from different images, Position and deriving the geometric calibration from the positions in the respective images of the corresponding descriptors. A target location in the image captured by a first optical sighting apparatus is designated and a corresponding location relative to the image captured by the second one optical sighting apparatus is identified from the geometric calibration. The display device of the second optical sighting apparatus indicates where the corresponding location lies relative to the displayed image.
