Machine-vision-based Spindle Positioning System of Grinding-wheel-saw Automatic Replacement System

To improve the working efficiency and safety of steel round bar sawing equipment, a grinding-wheel-saw automatic replacement system has been employed to replace grinding-wheel saws.In this paper, we report a machine-vision-based spindle positioning system for spindle localization in this replacement system.The hardware and software for the spindle positioning system were established, as well as an imaging model of the camera and the calibration of the vision system.The template matching approach applied to identify the shaft nut of the spindle is also described.Experimental results clearly demonstrate the effectiveness of the proposed machine-vision-based system.
