Practical applications for robotic arms using image processing

摘要

The following paper presents various applications for a robotic arm using image processing. These applications have as a basis a video camera that captures the images to be processed for either recognition and sorting or for contour coordinates extraction. Based on these captures, there were developed algorithms that enable the arm to either sort objects recognized to be having different shapes, or to draw shapes based on the coordinates received. Both the object detection and the contour coordinates extraction methods are implemented using a series of image processing techniques like border extraction, contour detection, contour extraction, along with match template and the aid of OpenCV library. Also, a PI controller that ensures the position of the robotic arm was developed.
