Real-time Product Quality Inspection Monitoring System using Quadratic Distance and Level Classifier

Automated product quality inspection has become a very important process in industries to maintain high product efficiency. This paper presents a real-time product quality inspection monitoring system for beverages product. The proposed system used Internet Protocol (IP) camera to capture the image of the bottle through computer network in order to inspect color concentration and water level of the bottle. Quadratic distance technique is applied for color concentration analysis based on a combination of Red, Green and Blue (RGB) histogram. The vertical and horizontal coordinates technique is used to inspect three conditions of the level, which are passed, overfill and underfill. The proposed system has achieved 100% accuracy using 246 samples

A Review Of Vision Based Defect Detection Using Image Processing Techniques For Beverage Manufacturing Industry

Vision based quality inspection emerged as a prime candidate in beverage manufacturing industry. It functions to control the product quality for the large scale industries; not only to save time, cost and labour, but also to secure a competitive advantage. It is a requirement of International Organization for Standardization (ISO) 9001, to appease the customer satisfaction in term of frequent improvement of the quality of products and services. It is totally impractical to rely on human inspector to handle a large scale quality control production because human has major drawback in their performance such as inconsistency and time consuming. This article reviews defect detection using image processing techniques for beverage manufacturing industry. There are comparative studies on techniques suggested by previous researchers. This review focuses on shape defect detection, color concentration inspection and level of liquid products measurement in a container. Shape, color and level defects are the main concern for bottle inspection in beverage manufacturing industry. The development of practical testing and the services performance are also discussed in this paper
