AppleBBCH81 (Apple Fruits BBCH 81-85)

The photo fixation of apple fruits was done in the LatHort orchard in Dobele, at the maturity of fruit and seed (BBCH stage 81-85). BBCH-scale describes the phenological development of grapes: 8 - maturity of fruit and seed; 81 - beginning of ripening; 85 - advanced ripening. Two photo images were taken for each tree – perpendicularly, in a tree-facing view and in an oblique view. The images were annotated using the tool makesense.ai. Then the annotated images 3008x2000 were automatically cropped out on 640x640 images with overlap 30% and validated manually. The images were saved in YOLO format.
