Abstract (en)
[origin: WO2013006109A1] The present invention relates to a sheet metal folding measurement method and device (100) for monitoring a folding process in real-time. The device (100) comprises a time- of-flight (TOF) sensor (120), a processing unit (140) and an output unit (160). The TOF sensor (120) is adapted and configured to capture a range image frame (170) representative of the distance between the TOF sensor (120) and a measured surface area (220) of the metal sheet (200). The processing unit (140) is configured to determine a two dimensional angle variable between the surface area (220) and a reference surface (R) and deliver the two dimensional angle variable as an output (165).
