Abstract

Die Erfindung bezieht sich auf ein Verfahren zur Ermittlung eines Gesamtdatensatzes eines zu messenden Objekts unter Verwendung von Einzeldatensätzen, denen Einzelscans des Objekts zu Grunde liegen, die mit zumindest einem Sensor gemessen werden. Um sich akkumulierende Fehler zu vermeiden und ein Entzerren bzw. Korrigieren einzelner Daten zu ermöglichen, wird vorgeschlagen, dass mittels zumindest eines ersten Sensors erste Teilscans des Objekts gemessen werden, die mittels zweiter Teilscans von zumindest zwei in ortsfester Beziehung angeordneten zweiten Sensoren zueinander ausgerichtet und/oder korrigiert werden und aus den zueinander ausgerichteten und/oder korrigierten Teilscans die Einzeldatensätze für den Gesamtdatensatz ermittelt werden.
