Abstract:
A method for acquiring images of a scene, from a moving carrier that is equipped with a sensor comprises a step in which images of the scene are acquired during the movement of the carrier, and a step in which the angular direction of the line of sight of the sensor is automatically controlled. The acquisition is carried out: for a first position of the carrier, with automatic control allowing an outward scan, combined with a scan in step-and-stare mode with a biaxial stare micro-movement, of a band of terrain of the scene to be carried out, a first strip of images thus being acquired, and wherein at least one other strip of images of the same zone of terrain is acquired by reiterating these scanning steps for at least one other position of the carrier, each image of another strip being acquired with a preset degree of overlap with the images of the first strip.

Claim (Index 1):
A method for acquiring images of a preset ground scene, from a carrier that is moving along a path, and that is equipped with an optical sensor having a line of sight, which comprises a step wherein the sensor acquires successive images of the scene during the movement of the carrier, and a step in which the angular direction of the line of sight is automatically controlled by a processing unit that is connected to the sensor, the acquisition being carried out:\n for a first position of the carrier on its path, with automatic control of the angular direction of the line of sight allowing what is called an outward scan, combined with a scan in step-and-stare mode, of a preset band of terrain of the scene to be carried out, a first strip of images thus being acquired; and wherein at least one other strip of images of the same zone of terrain as the first strip is acquired by reiterating these scanning steps for at least one other position of the carrier on its path, each image of another strip of a terrain-band segment being acquired, for the same terrain-band segment, with a degree of overlap with the one or more images of the first strip that is higher than a preset high degree of overlap, the overlapping images of one strip to the next, i.e. images of the same terrain segment, being thus acquired in these iterations in various directions of the line of sight, respectively; wherein the step-and-stare mode, which includes steps, i.e. translational micro-movements, having an amplitude controlled by the processing unit, comprises:\n at least one step, called a sideways step, having a main component that is perpendicular to the outward scan, combined with \n at least one step, called a longitudinal step, having a main component that is parallel to the outward scan, and \n a biaxial stare micro-movement in order to compensate for a translational movement of the line of sight during the acquisition of each image, \n and wherein the automatic control of the angular direction of the line of sight is achieved by carrying out image processing on the acquired images.
