- This paper presents the structure and operational principles of the Automatic Waterjet Positioning Vision System (PVS), which was implemented on the WaterJet (WJ) machine. Moreover, it presents an impact of calibration method on PVS performance. Two webcams mounted on the industrial WJ, form a basis of the system, and constitute its characteristics features. Together with the identification algorithm, the PVS was aimed for high accuracy positioning of the WJ machine. For this purpose, the two-step calibration procedure that uses a set of specific calibration color markers contrasted to the background, has been developed. The results analysis shows that, despite demanding environmental conditions, the proposed methodenables reliable high accuracy positioning of the WJ machine.
