Apple is one of the most famous fruits that have been picked by a lot of families in Malaysia. There are several factors that determine apple quality which are volume and weight. The two parameters have been used as a benchmark to identify the quality of apples. These two parameters can be easily measured individually by using a weighing balance to measure weight and water displacement method (WDM) to measure volume. However, these two methods are not suitable to apply in industries since both methods required a lot of time to obtain the final output. Therefore, new technology is needed in order to estimate the weight and volume of apples. The main objective of this project is to develop a vision-based system that is able to estimate the volume and weight of apples. The volume of the apple is calculated by using the width and height of the apple via images. The camera needs to calibrate in order to get the ratio of pixel/cm which is used for conversion data. Detectron2 with a custom dataset will be used to detect and segment apple images. The output of detection and segmentation images will be used to create boundary boxes to obtain the height and width of apples. The developed systems are tested by four different settings which have different variables. The volume and weight of apples are able to obtain 85.41% and 85.26% of accuracy by using the formula. Overall, the project is able to estimate all the parameters of apple with an accuracy of more than 80% which can be concluded as a successful project.
