ABSTRACT:
The present invention relates to a device that measures and counts near surface bubbles on a copper bar, as well as the cracks on the lateral sides. The device detects said flaws in real time. The device is based on the image digitalization technique. The device consists of a personal computer, a video camera, a digitalization card, water and air sprinklers, external monitor and camera frame. The input of the images is performed with the video camera protected within the frame. The object of the water and air sprinklers is to make the bar flaws more visible. The external monitor allows to focus the area of interest and the digitalizing card within the computer, following the instructions of the program, performs the image analysis.
