Abstract

Die Erfindung betrifft eine Vorrichtung (14) zum Laserscannen, mit einem Laserscanner (1), der mit einem Meßstrahl (2) einen Abtastwinkel (a, O) überstreicht, um an seinem Ausgang (17) eine Folge (7) von winkelmäßig aufeinanderfolgenden Entfernungsmeßpunkten (5) zu erzeugen, wobei an den Ausgang des Laserscanners (1) ein steuerbares Unterabtastglied angeschaltet ist, dessen Unterabtastung abhängig von der Winkelstellung des Meßstrahls (2) gesteuert ist. Die Erfindung betrifftferner ein Verfahren zum Laserscannen mit Hilfe eines solchen Laserscanners.The invention relates to a device (14) for laser scanning, comprising a laser scanner (1) sweeping a scanning angle (a, O) with a measuring beam (2) to produce at its output (17) a sequence (7) of angularly successive distance measuring points (5), wherein at the output of the laser scanner (1) a controllable sub-scanning is turned on, the undersampling of which is controlled depending on the angular position of the measuring beam (2). The invention further relates to a method for laser scanning with the aid of such a laser scanner.
