Method, computer program product and measuring system for operating at least one triangulation laser scanner for identifying surface properties of a workpiece to be measured

摘要

The invention relates to a method 40, a computer program product and a measuring system 18 for operating at least one triangulation laser scanner 1 for identifying surface properties of a workpiece 7 to be measured by means of the at least one triangulation laser scanner, the at least one triangulation laser scanner 1 comprising a CMOS sensor chip 11 , an imaging optics 9 and a laser line light source 3 for generating a laser line on the workpiece to be measured 7 under a Scheimpflug condition, wherein the data generated on the CMOS sensor chip 11 in an image recording data is reduced to an amount of data which only the data of Lateral actual position of the pixels of the laser line and the data comprises at least one quality criterion for each of the pixels of the laser line, wherein the quality criterion is a measure of the intensity distribution along a direction transverse to the local extension direction of the pixels Laser line on the CMOS sensor chip and wherein the reduced amount of data with respect to the quality criterion by means of at least one evaluation unit 30 with respect to the presence of bar and / or recognition code information 13 and / or texture information 15 is analyzed.
