Design of orange grading system based on real time image processing

Abstract

Orange is one of preference agricultural products by consumers, because it has several benefits suchas vitamin C and antioxidants. The fruit is often used for gift when someone visits the relatives, thus the quality of orange is mostly detected by visual suchas size and skin color of the fruit. Determination of the quality is done manually because it takes faster. The manual grading has the weakness and less effisien, resulting several quality gradings and needs man power more. Using the man power tend to be subjective judgement. One of the ways to increase the productivity to determine the orange quality is that using grading methode using technology real time digital analysis mechanically. The aims of the resarch is to design of grading machine and grading program based on diameter and skin color of the orange that analysed by real time image processing. Based on the research result, this system can be applied on orange grading. The capacity of the manual grading is 1,276 fruit/hour,meanwhile capacity of the grading system is 712.87 fruit/hour. From the speed of the process and grading capacity, the manual methode is better instead of grading system using image processing. Meanwhile for the quality of the grading, Using the grading system based on the image processing can be said that it is suitable toward the standard. If using manual grading, it use the principle of habit, without really measure specifically and detail.
