Workstation – General Idea of Paper Reel Center Positioning
Vision software processing:
1. Grab the center of the paper roll with the circle-finding tool, and take the center of the circle as the positioning point.
2. The positioning data can be sent through TCP / IP , serial port and other communication methods.

Workstation – Center Positioning Processing Effect of Paper Reel
By grabbing the center of the paper roll (outer or inner) as the center:
The paper roll is annular, the image transition pixels are complex and unstable, and the outline of the paper roll is not regular, which will affect the measurement of size data.
The outer circle of the paper roll will be covered by the edge of the paper, and the circle outline found is not necessarily the outer circle outline, which easily affects the positioning of the center of the circle.
The edge of the inner circle of the paper roll needs to be flat. If the edge has gaps, curling, and fluctuations in incoming materials, it will affect the effect of finding the circle and affect the accuracy of the center of the circle.
