Target-identification arrangement with an imaging sensor, a signal-processing coupling and an evaluation coupling with a computer for grey scale value analysis of the output signals from the imaging sensor, the signal- processing coupling containing a threshold detector for lightness transitions and for the local extreme values, a sorting based on three words - light/desired/dark - taking place in the signal-evaluation coupling, a surface centre of gravity for the target being established from this, in particular by generating the coordinates of the target, and the computer, for target identification, after locating by comparison of the measured parameter with the stored parameters, also interpreting in the evaluation coupling the sign for the gradient image obtained for target direction determination, and in the computer, in addition to a binary image (edges and non- edges), edge points lying on a straight line also appear, especially from one or more image sections. <IMAGE> |
