Design of Automatic Vision-based Inspection System for Monitoring in an Olive Oil Bottling Line

Abstract

Automated vision inspection has become a vital part of the quality monitoring process. This paper compares the development and performance of two methodologies for a machine vision inspection system online for high speed conveyor. The first method developed is the Thresholding technique image processing algorithms and the second method is based on the edge detection. A case study was conducted to benchmark these two methods. Special effort has been put in the design of the defect detection algorithms to reach two main objectives: accurate feature extraction and on-line capabilities, both considering robustness and low processing time. An on-line implementation to inspect bottles is reported using new communication technique with GigE Vision camera and industrial Gigabit Ethernet network. The system is validated on olive oil bed. The implementation of our algorithm results in an effective real-time object tracking. The validity of the approach is illustrated by the presentation of experiment results obtained using the methods described in this paper.

Design of Automated Visual Inspection System for Beverage Industry Production Line

“…The empty bottle detection technique has been discussed by Duan et al [18]. Vision-based inspection of olive oil bottling plant has been discussed by Abdelhedi et al [19]. A programmable logic controller (PLC) has been used to control the conveyor belt of a bottling plant [20].…”

Novel technologies for monitoring the in‐line quality of virgin olive oil during manufacturing and storage

“…In 2012, Abdelhedi et al developed a vision system to check an olive oil bottling process. Two defects were studied: no presence of caps and insufficient level of olive oil.…”

“…Image processing system for cap detection and oil level verification with sufficient precision for real time bottling production monitoring 87 Quality checking of olive oil bottling process (detection of cap) using computer vision…”

“…Specifically, in the production of olive oil, two works have been developed for detecting bottling quality; these are focused on the presence of caps and filling level. In 2012, Abdelhedi et al 87 developed a vision system to check an olive oil bottling process. Two defects were studied: no presence of caps and insufficient level of olive oil.…”
