Abstract— Quality assurance of packaged products is of critical importance in the pharmaceutical industry so as to overcome expensive manufacturer recalls or potentially fatal accidents. This paper proposes a low cost yet efficient automatic quality monitoring system of tablet packs for small scale pharmaceutical companies. The proposed system inspects tablet packs by installing a camera and by using embedded vision technology. LabView is used to process the image for fault detection, using IMAQ vision toolbox to check for missing tablets, damaged tablets, dimension mismatch and colour difference between tablets. Further, identified faulty tablet packs moving on a conveyor belt will be rejected by the rejection arm automatically upon receiving control signals from the microcontroller.
Keywords— Embedded Vision, IMAQ vision toolbox, LabView.
