Patent ID: 6847740

Claim:
A method for an optical detection of object streams, wherein surfaces of the moving object streams are capable of reflecting or scattering light, and wherein the object streams are capable of providing self-similar patterns or structures on the surfaces of the object streams comprising: employing an illuminating device for illuminating the object streams capable of reflecting and scattering light; generating patterns derived from the surfaces of the object streams when the surfaces of the object streams are illuminated by the illuminating device; scanning an imaging ray bundle reflected from the surfaces of the object streams and scattered by the object streams based on a similitude-transformation algorithm wherein the scanning is performed by an optical imaging and receiving device and wherein a result of the scanning is a sequence of imaging light patterns, and wherein a connection of individual light patterns to each other is at least one of spatially and timely and is a self-similar transformation of individual light patterns; setting up at least two variables; storing of detection events, resulting from the scanning over variables, in a form of value pairs, performed within a memory storage in an affine transformation; calculating a self-similar transformation function performed by way of a logarithm of the at least two variables of the self-similar transformation.
