ABSTRACT:
A wide-field infrared camera, with a fixed focal distance, generates a wide-field image which is displayed by a first monitor adapted to display and superimpose the wide-field image on a scene viewed in a head-up visor for example. An image processor generates a signal representing a small-field image, which is a portion of the wide-field image, with an adjustable enlargement and an adjustable position within the wide-field image, and computes the elevation of the bearing of a point of interest at the center of the small-field image. A second monitor is provided to display the small-field image as is a laser telemeter and an aiming device to servo-control the line of sight of the telemeter in such a way that it always corresponds to the center of the small-field image. The arrangement can be applied to the three-dimensional localization of a point of interest, for a navigational resetting operation or for a firing control operation.
