Abstract
This project is about the development of a system to detect objects like circles in real-time processing. This system can be adapted to the automation industries to modify for defects detection and location upon objects detection. Objects will be setting onto the conveyor belt, passing through by scanning the targeted objects with the ‘robotic eye’, which is the CCD camera. High speed image processing will be conducted to ensure the detection upon purposes. In this project, detection of center of circles is highlighted. CHT will be implemented, mapping each possible edge into horizontal and vertical components into accumulator. The center of the circles can be then estimated by analyzing the accumulator. The data of the estimated center of circles will be sent to the robotic part through serial communication to act upon the data received, locating and pointing to the center of circles. The output of the processing can be shown on monitor as well if required.
