- Abstract
To increase the process reliability of laser flatbed machines, it is advantageous to be able to predict whether a part will tilt after cutting. This is only possible if the position of the slats under the sheet to be cut is known. The detection of the slats is possible with grey scale images in the visible spectrum, but this method proved not very robust. In this work a narrow-band near-infrared dark field illumination is investigated, which is able to detect the slats and single support tips robustly, fast and with high accuracy. An appropriate illumination position is identified and suitable image processing algorithms are presented. With the proposed measuring system, the detection of slats is possible without errors, while supporting tips are detected with an accuracy of 93 %.
