UAV Canyelles Vineyard Dataset 2023-05-05

The dataset includes the following components:

RGB(1-3): contains 1359 RGB images captured using a DJI Mavic 3 Classic UAV. The images are stored in JPG format, with metadata that includes location information, camera settings and capture dates.

SHAPE: contains the shape file used in Metashape Agisoft to crop the point cloud, orthomosaics and DEM, ensuring a clear visualization of the vineyard rows.

POINTCLOUDS: includes both the raw and cropped point clouds, processed using Metashape Agisoft, and stored in XYZ format (.txt).

ORTHOMOSAICS: includes the original and cropped orthomosaic images, generated with Metashape Agisoft, in TIF format.

DEM: contains the original and cropped DEM images, also processed using Metashape Agisoft, and stored in TIF format.

This data is aligned with the rest of UAV Canyelles Vineyard Datasets uploaded by Noumena (UC1), so different orthomosaics / pointclouds / DEM of different dates can be analyzed jointly for cropped and uncropped files. 

Data collection took place on May 5th, 2023, in Canyelles, Catalonia, Spain. The UAV was flown at an altitude of 10 meters, ensuring sufficient frontal and side overlap between images.

本数据集包含以下组成部分：

RGB(1-3)：包含1359张由DJI Mavic 3 Classic无人机(Unmanned Aerial Vehicle, UAV)采集的RGB图像，图像以JPG格式存储，附带包含位置信息、相机参数及拍摄日期的元数据。

形状文件集（SHAPE）：包含用于Agisoft Metashape软件中对点云、正射影像及数字高程模型(DEM, Digital Elevation Model)进行裁剪的文件，以确保葡萄园航带的可视化效果清晰。

点云数据集（POINTCLOUDS）：包含经Agisoft Metashape处理的原始点云与裁剪后点云，存储为XYZ格式(.txt)文件。

正射影像集（ORTHOMOSAICS）：包含经Agisoft Metashape生成的原始正射影像与裁剪后正射影像，格式为TIF。

数字高程模型（DEM）：包含经Agisoft Metashape处理的原始数字高程模型与裁剪后数字高程模型，存储为TIF格式。

本数据集与Noumena上传的其余UAV坎耶莱斯葡萄园数据集（UC1）对齐，因此可联合分析不同日期采集的正射影像、点云及数字高程模型的裁剪与未裁剪文件。

数据采集于2023年5月5日，采集地点为西班牙加泰罗尼亚自治区坎耶莱斯(Canyelles)。无人机飞行高度为10米，确保图像间具备足够的航向与旁向重叠度。
