Estimation Of Fruits Volume And Mass Using A Single Top-View Image: A Case Study Of Kiwifruits And Sapodilla Fruits

Abstract

Image processing technology is considered one of the very useful new technologies in the food industry. In particular, the image processing method is effectively applied in the process of food quality inspection and classification based on shape and size parameters. At the same time, the development potential of this technology is huge so that researchers have applied this technology to fruit production lines with the purpose to improve the time and efficiency of the process. This report aims to accomplish three main objectives. First, this paper proposes a computer vision system capable of estimating the volume and weight of fruits based on size parameters such as length and width of the fruits. Second, the system is designed to use only one camera to capture a top-view image, which gives this system the advantage of low cost when compare to systems using multiple cameras or three-dimensional (3D) cameras. Finally, this article provides a solution which is low cost, short processing time and high accuracy in the food inspection process. In this article, our approach was applied to a case study of egg shaped fruits such as kiwi and sapodilla.
