The present invention relates to a process and a device for determining the location of a target (C) observed in the field of view of an optical detector. According to the invention, the process is notable in that: in a preliminary step, there are determined, at least one partial image (9, 10) of the background and one partial image (11) of the target (C); and next: a picture (V1) is taken; at least one background search window (19) is isolated from said picture (V1); the partial image (9) of the background is searched for in said search window (19); the movement of the optical detector is determined from the position of this partial image (9); a target search window (26) is isolated; the partial image (11) of the target is searched for in said search window (26); and the movement of the target (C) is determined from the position of this partial image (11).
