PANTOGRAPHY APPLICATION WITH REAL-TIME PLC BASED ON IMAGE PROCESSING IN GANTRY ROBOT SYSTEM

Abstract

Programmable Logic Controllers (PLC) is one of the indispensable products of automation industry. PLCs, which are widely used in many fields of programming, make our lives easier in daily life. In this study, after determining the coordinates of the image taken from the camera with the help of image processing algorithm, the servo drives of cartesian machine are controlled and processed in X-Y plane with Rexroth PLC in real time. In this application, it is aimed to obtain the image again by subtracting the boundary coordinates of the image taken with the camera in MatLab environment. To achieve this goal, the servo drives of the cartesian machine were controlled and the application was realized. Two different methods were applied for the image taken in Matlab environment. The skeleton of the image was taken for the first method and then the boundary coordinates were determined. For the second method, the contour of the image was first extracted. The coordinates of the contour image were not directly used. These coordinates have been tried to be optimized. In this study, it is aimed to draw a desired image by drawing border coordinates in Matlab with Rexroth PLC on a cartesian machine. As a result of the test studies, it was seen that the drawing process was carried out properly (according to the coordinates received) as a result of the analysis and measurement processes (metric caliper and measurement methods).
