the paper presents the unique system for automatic sorting of pallets. System has tree units: sensor unit, electronic unit and PC. System can detect defect, slope of pallet surface or foreign object on the pallet surface. The description of the user interface and the testing results of the pallet are presented. The calculated values are compared with a normalized value and if a deviation is beyond the tolerance, the pallet is rejected. The software allows you to display results in the form of 3D images of the surface of the pallet for visual observation by the operator on the display.Keywords-height of the pallet, defect, slope of pallet surface, foreign object on pallet surface, block diagram, velocity, 3D images, alarm sounds
