AgroTwin Drone Vineyard Dataset 2024

The drone data was collected in Cesa (Italy) in 3 surveys from half May 2024 to early July 2024. Each survey was composed of 2 drone flights, one with the camera in nadir position (i.e., 90°) and the other with the camera positioned at 30° to the horizon (inclined mode), both at an altitude of 30 meters above ground level and with 85% front and side image overlaps. Furthermore, we conducted a sensitivity analysis. In particular we performed a series of surveys having the following flight characteristics: h30-fo85-so90-30° h30-fo85-so90-nadir h30-fo90-so90-30° h30-fo90-so90-nadir h50-fo85-so80-30° h50-fo85-so80-nadir h50-fo85-so90-30° h50-fo85-so90-nadir h50-fo90-so90-nadir where: h=height, fo=Front Overlap, so=Side Overlap. The dataset comprises the following data: "UAV RGB Images": This folder contains multiple subfolders, each holding a collection of RGB images in a specific phenological stage collected with different camera angle (nadir and 30°). The "Sensitivity_Images" folder contains the sensitivity RGB images as described previously. The image where collected using the DJI Phantom 3 Professional and encoded in the JPG format (.jpg). The image metadata includes GNSS information, camera settings, and capture dates. "Pointclouds": The "Pointclouds" folder contains multiple 3D point clouds data generated from RGB images using OpenDroneMap open-source photogrammetric software. In the sensitivity analysis, a 3D point cloud has been processed for each type of flight (30°, Nadir and Nadir+30°). The 3D point cloud data was created with high resolution and was saved in ply format (.ply).本无人机数据集采集自意大利切萨（Cesa）地区，于2024年5月中旬至2024年7月初期间开展了3次航测作业。每次航测均包含2次无人机飞行：一次采用天底视角（nadir，即相机与地面垂直的90°俯拍），另一次采用与地平线成30°夹角的倾斜拍摄模式（inclined mode），两次飞行的飞行高度均为距地面30米，且前后向与旁向图像重叠率均为85%。 此外，本研究开展了敏感性分析，具体实施了一系列具有不同飞行参数的航测作业，其飞行特征标识如下： h30-fo85-so90-30° h30-fo85-so90-nadir h30-fo90-so90-30° h30-fo90-so90-nadir h50-fo85-so80-30° h50-fo85-so80-nadir h50-fo85-so90-30° h50-fo85-so90-nadir h50-fo90-so90-nadir 其中，h代表飞行高度（height），fo代表前向重叠率（Front Overlap），so代表旁向重叠率（Side Overlap）。 本数据集包含以下两类数据： "UAV RGB Images"：该文件夹下包含多个子文件夹，每个子文件夹均存储了特定物候期下、采用不同相机视角（天底视角与30°倾斜视角）采集的RGB影像集合。其中"Sensitivity_Images"文件夹即包含前文所述的敏感性分析所用RGB影像。本数据集的影像均采用DJI Phantom 3 Professional无人机采集，编码格式为JPEG（.jpg），影像元数据包含GNSS信息、相机参数及拍摄日期。 "Pointclouds"：该文件夹包含利用开源摄影测量软件OpenDroneMap从RGB影像生成的多组三维点云数据。在敏感性分析中，针对每一种飞行模式（30°倾斜视角、天底视角以及天底+30°混合视角）均生成了对应的三维点云。本数据集的三维点云为高分辨率数据，保存格式为PLY（.ply）。
