Vorrichtung und Verfahren zum Erfassen eines Objekts in einem vorgegebenen Raumbereich, insbesondere von Fahrzeugen für die Verkehrsüberwachung

摘要

When detecting an object in a given area, especially vehicles for the purposes of traffic control, there appear to be inaccuracies in the system based on measuring pulse propagation times. In order to avoid such inaccuracies, a sample of observed (measured) real values is compared with a gauging table having a sample of values stored therein, so that pulse propagation time measurements are no longer necessary.
