Method for detecting defects of a pallet, especially in the nailing, by combining optical and thermographic inspection.
Optical inspection is carried out by a camera or a laser scanner and subsequently, a 3d-model is created. For the thermographic inspection, the metal in the pallet is heated by electromagnetic induction and a thermal image is recorded. The position of the nails is then registerd in the optical 3d-model. If defects are detected, their positions are determined and a label is attached at the position of each defect. |
