METHOD AND DEVICE FOR DETECTING AND MAKING SIGNAL SHAPES COINCIDENTAL, SAID SHAPES BEING CONVERTIBLE INTO MONOTONE AND CONSTANT TRAJECTORIES IN A SECTION BY SECTION MANNER

摘要

A method and apparatus to segment-wise detect and bring into coincidencesignalwaveforms which can be converted into monotone and continuous trajectories, inparticularfor purposes of real-time pattern recognition, localization and monitoringoptical and acousticsignals and to determine transit-time differentials.The desired monotone and continuous trajectories are made to coincide intranslation-invariant manner with the key signal waveforms which are alsostorable inreconfigurable manner. The said method and apparatus therefore detects in avery shorttime said trajectories with high accuracy of measurement.Even in other applications (Fig. 3), the determination of transit-timedifferentialsimplemented by the method of the invention takes the form of detecting keysignalwaveforms in the upper or lower signal detection unit C1a or C1b and infurther processingthe data in the subsequent multi-coincidence unit C2, shift-invariant parallelmulti-templatematching being carried out in the detection units C1a and C1b, wherein thetrajectories arecorrelated in parallel and a set of transit-time differentials in the form ofan output vector Dbeing emitted from the subsequent multi-coincidence unit C2.The method is suitable to accurately determine trajectories and accordingly isusefulfor instance to localize signal sources in space, to measure displacementtrajectories, tomeasure speed and acceleration, etc.
