Highly Efficient Fruit Mass and Size Estimation Using Only Top View Images

This paper presents a new methodology for the estimation of the mass and size of a common Vietnamese fruit, the cavendish-type banana. We only used top-view images. Most previous works focused on volume estimation using a plurality of cameras to infer the three-dimensional information. In this work, we only used a single camera mounted on top of the fruit. We have found that our proposal leads to a relatively small estimation error (approximately 6%) compared to the results obtained from the measurements using a water-displacement method and a static digital scale. The results indicate that our system shows a great potential to be used in a real industrial setting. Future work will aim to investigate other features such as ripeness and bruises to increase the effectiveness and practicality of the system.
