Abstract
Images of a scene are acquired from a moving carrier that is equipped with a sensor. 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, at least one other strip of images of the same zone of terrain being acquired by reiterating these scanning steps for at least one other position of the carrier, and each image of another strip being acquired with a preset degree of overlap with the images of the first strip.
