Abstract: The present invention is generally concerned with electronic vision devices and methods, and is specifically concerned with image augmentation in combination with navigation, position, and attitude devices. In the simplest form, devices of the invention can be envisioned to include six major components: A 1) camera to collect optical information about a real scene and present that information as an electronic signal to; a 2) computer processor; a 3) device to measure the position of the camera; and a 4) device to measure the attitude of the camera (direction of the optic axis), thus uniquely identifying the scene being viewed, and thus identifying a location in; a 5) data base where information associated with various scenes is stored, the computer processor combines the data from the camera and the data base and perfects a single image to be presented at; a 6) display whose image is continuously aligned to the real scene as it is viewed by the user.

Abstract: Vision systems having knowledge of position and attitude can reliably determine what scenes are being addressed by the system. Real images of the scene can then be augmented with computer generated information which relates to the known scene. A determination of position and attitude of the device identifies which scene is being addressed. A computer recalls information regarding the scene and generates imagery according to that recalled information. The computer generated imagery is then combined with an image of the scene to form an augmented image which is presented to the user aligned to the viewing direction of the device.
