ABSTRACT:
A method and apparatus for the automatic evaluation of stereoscopic images by the determination of the maximum degree of correlation of identical images of an object reproduced by two objectives, for example for a range finder, wherein the two images are superimposed on one and/or two position frequency filters (82, 21, 31, 32) identical in their structures; the respective superimposed signal produced is fed respectively to one photoelectric receiver (13,14,43,44); and the output signals of the photoelectric receivers are used for indicating and/or control purposes. In one embodiment the position frequency filter (82) is moved and the output signals are correlated with each other. In another embodiment the output signals are subtracted from each other.
