A method for identifying within a working image of a scene a point of interest designated within a designation image of a scene, the designation image being taken along a first viewing direction and the working image being taken along a second viewing direction, the second viewing direction being significantly non-parallel to the first viewing direction, the method comprising the steps of: obtaining a designation image of the scene; obtaining a working image of the scene; correlating said designation image and said working image with each other, directly or by correlating each of said designation image and said working image with a common reference image, so as to derive an interrelation between said designation image and said working image; and employing said interrelation between said designation image and said working image to derive a location within said working image of a point of interest designated within said designation image, characterized in that the method further comprises: obtaining a secondary designation image taken along a viewing direction displaced from, but similar to, the first viewing direction; and co-processing said designation image and said secondary designation image to derive range information relating to a plurality of pixels in said designation image, thereby defining a partial relative three-dimensional model of a portion of the scene relative to the viewing direction of said designation image, wherein said partial relative three-dimensional model is used in said step of correlating.

Methods for transferring points of interest between images with non-parallel viewing directions

A method for deriving three-dimensional information progressively from a streaming video sequence.

Method, systems and computer product for deriving three-dimensional information progressively from a streaming video sequence

A method for sharing visual situational information of objects among a number of command and control units. The method includes the steps of providing to each command and control unit a mechanism for storing a digital reference map of a geographical area, receiving by one or more command and control unit an image of a scene which includes one or more object within the geographical area, registration of the received image of the scene to the digital reference map, updating a situational information of the object in the reference map, and transferring the updating of the situational information to one or more other command and control unit.

Method and system for improving situational awareness of command and control units

A system and method for providing images of a searching area and for assisting the visual orientation of a user observing the images of the area is provided. The system includes a reference memory, a camera, a transformation unit and a display unit. The reference memory stores a wide field of view (FOV) reference image of the searching area. The camera produces zoomed images of selected portions of the searching area, the zoomed images of the selected portions having an FOV not greater than the wide FOV of the reference image. Transformation means generate transformations between each of the zoomed images and the reference image, and the display means displays both the wide FOV reference image and one of the zoomed images currently viewed by the camera and, on the reference image, displays a frame indicating where, within the searching area, the camera is currently viewing the selected portion of the searching area.
