Fruit size information through the season is an important parameter allowing growers to better manage the orchard. In this study, a Python based computer vision algorithm for sizing apples directly on-the-tree was developed. The system was made of a consumer-grade depth camera and tested at two distances and different timings through the season, in a Fuji apple orchard. The system exploited a YOLOv5 detection algorithm and a trigonometric approach based on depth information to size the fruits. Results showed potential field application even if a further system improvement to reduce the sizing error (RMSE <10 mm) need to be achieved.

Abstract
Fruit size information through the season is an important parameter allowing growers to better manage the orchard. In this study, a Python based computer vision algorithm for sizing apples directly on-the-tree was developed. The system was made of a consumer-grade depth camera and tested at two distances and different timings through the season, in a Fuji apple orchard. The system exploited a YOLOv5 detection algorithm and a trigonometric approach based on depth information to size the fruits. Results showed potential field application even if a further system improvement to reduce the sizing error (RMSE <10 mm) need to be achieved.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
