摘要:
Method for measuring an extruded profile using a measuring apparatus, wherein the measuring apparatus is designed to produce and measure at least two laser light sections on a surface of the profile, which is being pulled through the measuring apparatus, by means of at least one laser light section sensor from a respective, different position around the profile, wherein the at least two laser light sections are situated essentially in one plane. By positioning at least two references and/or reference markers from the adjacent positions together with the extruded profile in a respective common measurement capture area, said references or reference markers are used for calibration of respective raw image of the at least one laser light section sensor. Thus, the calibrated raw image data are correctly mapped in a common coordinate system from the respective position.
