Abstract

A method, a computer program product and a measuring system are provided for operating a triangulation laser scanner to identify surface properties of a workpiece. The scanner has a CMOS sensor chip, an imaging optical unit, and a laser line light source configured to generate a laser line on the workpiece in compliance with a Scheimpflug condition. Data generated on the sensor chip is reduced to an amount of data only including actual lateral positions of image points of the laser line and a quality criterion for each of the image points. The quality criterion is a measure of an intensity distribution along a direction transverse to a local direction of extent of the image points of the laser line on the sensor chip and the reduced amount of data is analyzed with respect to the quality criterion regarding a presence of barcode and/or detection code information and/or texture information.
