Abstract

This paper describes the operations and performance of an automated quality verification system for agricultural products and its main features. The system utilizes improved engineering designs and image-processing techniques to convey and grade products. Basically two inspection stages of the system can be identified: external fruit inspection and internal fruit inspection. Surface inspection is accomplished through processing of color CCD images while internal inspection employs special sensors for sugar and acid content. An X-ray sensor is incorporated to detect biological defects.
