Christmas greeting made using 3D Photogrammetry and Artificial Intelligence techniques

Characteristics of the greeting:
- 3D point cloud with 7 milion points (watch the whole 3D point cloud in the following link: http://www.grap.udl.cat/documents/photogrammetry_fruit_detection.html).
- Made using Structure from Motion (SfM) and Multi-View Stereo (MVS) photogrammetry techniques.
- From 425 photographs.
- Acquired every 22 cm from 1,7 m above ground from 6 different angles.
- Crop: Fuji apple trees (Malus domestica Borkh. cv. Fuji).
- Fruits detected using Artificial Intelligence.
- 925 fruits detected automatically from 1021 present in the scene, with a Recall (true positives/total) = 0,906.
- Planting pattern of 4,0 m x 0,9 m, Max height of 3,5 m and Max width of 1,5 m.
- More information in the article Fruit detection and 3D location using instance segmentation neural networks and structure-from-motion photogrammetry, published in February 2020 (DOI: www.doi.org/10.1016/j.compag.2019.105165).
