The LFuji-air dataset contains 3D LiDAR data of 11 Fuji apple trees scanned from different sensor positions and applying different forced air flow conditions, allowing the analysis of using forced air flow and different sensor positioning for fruit detection, yield prediction and geometric characterization.

Pont clouds are saved as matrices in .mat format, where each row corresponds to a 3D point with the following information: [x-coordinate, y-coordinate, z-coordinate, calibrated reflectance]. Each point cloud file corresponds to an apple tree scanned with specific conditions. The file name describes the scanning conditions by the following code:

• H1: Trial scanned from height 1.8m.
• H2: Trial scanned from height 2.5m.
• n: Trial without forced air flow.
• af: Trial with forced air flow
• E: Point cloud acquired from the east tree row side.
• W: Point cloud acquired from the west tree row side.

Find more information about the scanning conditions in [1].

All point clouds were manually annotated with 3D rectangular bounding boxes on each apple position, annotating a total of 1,353 apples in all the dataset. Find annotations in .txt format inside “AllTrees_Groundtruth” folder. Each file corresponds to an apple annotation, where the first eight rows gives the 3D coordinates [x,y,z] of the bounding box corners, and the 9^th row corresponds to the bounding box centre.
