Detecting Apples in Orchards Using YOLOv3

2020
A machine vision system for detecting apples in orchards was developed. The system designed for use in harvesting robots is based on a YOLOv3 algorithm modification with pre- and postprocessing. As a result, apples that are blocked by leaves and branches, green apples on a green background, darkened apples are detected. Apple detection time averaged 19

TRAINING OF YOLOV5 FOR APPLE DETECTION IN ORCHARD

HUMAN. ENVIRONMENT. TECHNOLOGIES. Proceedings of the Students International Scientific and Practical Conference
Fruit cultivation is a significant part of the country economics and agriculture. In this paper, aiming to improve apple cultivation, we trained a neural network for apple detection using the YOLOv5 architecture, utilizing the dataset from the lzp-2021/1-0134 project. The dataset consisted of a set of apple tree photographs with apple fruits.

The Importance of Parasitoids in Apple Orchards

Biological Agriculture & Horticulture, 1997
ABSTRACT Sixty seven parasitoid species have been reared from leaf miners (Phyllonorycter blancardella Fabr., Ph. corylifoliella Haw., Leucoptera malifoliella Costa, Nepticula malella Stt.) and leaf rollers (Adoxophyes orana F.v.R., Pandemis heparana Den. et Schiff., Archips rosana L.).
