Abstract

Automated Visual Inspection System (AVIS) have a strong ability for quality control in manufacturing industries by inspecting products automatically instead of manual inspections. This paper gives methods for bottle inspection in manufacturing industries. The paper describes mechanism for the defect detection, top and bottom detection, cap placement and fill level inspection. For empty bottle inspection the image is processed by contrast enhancement and then circular Hough transform is used. The location and radius of top and bottom of bottle is analyzed. After filling the bottle with liquid and placing the cap, edge detection method is used which is followed by horizontal line detection to identify whether fill level and cap closure is appropriate or not. Presented bottle inspection system works with 100% accuracy in proper illumination condition.
