Zusammenfassung:	A pallet inspection system includes a frame configured to have a pallet receiving area to receive a wooden pallet to be inspected for having at least one mark indicating that wood in the pallet has been heat treated. Cameras are carried by the frame to generate images of the wooden pallet in response to the wooden pallet being in the pallet receiving area. A processor is to perform object detection on each image to detect if the mark is present, crop each image having the mark so that an area surrounding the mark within the image is removed, and perform image segmentation on each cropped image so that pixels within the cropped image are classified into regions. The processor determines readability of the regions in each cropped image based on respective readability criteria thresholds. The mark is classified in each cropped image as readable based on the mark meeting the respective readability criteria thresholds.
