Abstract: In the automation field product quality, time to market, number of workers required for the production, cost, technology, ease of availability of components etc. are all important considerations to increase the company profile in the market. All are depends on the controlling actions and the technology used for it. Based on the application different controlling actions are taken place like Programmable Logic Controller (PLC), Distributed Control System (DCS), Supervisory Control And Data Acquisition (SCADA), image processing etc. among these, image processing uses camera and the controller or processor for automation process. Here to increase the production speed, reduce the cost and based on ease of availability of components line scan sensor and Beagle Board is used for controlling the process. Using these, the line scan camera is designed and image processing is done for detecting the defects present in the object moving on the conveyor line and the controlling action will be taken by itself. Using single Beagle Board the camera is designed as well as controlling action is taken.
