UAV Canyelles Vineyard Dataset 2024-05-10

The dataset includes the following components:

RGB: contains 423 RGB images captured using a DJI Mavic 3M 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 pointcloud, orthomosaics and DEM, ensuring a clear visualization of the vineyard rows.

POINTCLOUDS: includes both the raw and cropped pointclouds in RGB, NIR, G, RE, R and NDVI. All of them were processed using Metashape Agisoft and stored in XYZ format (.txt).

ORTHOMOSAICS: includes the original and cropped orthomosaics in RGB, NIR, G, RE, R and NDVI. All of them were generated using Metashape Agisoft and are 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 10th, 2024, in Canyelles, Catalonia, Spain. The UAV was automatically flown at an altitude of 12 meters, ensuring sufficient frontal and side overlap between images.

本数据集包含以下组成部分：

RGB模块：包含423幅由DJI Mavic 3M无人机（Unmanned Aerial Vehicle, UAV）采集的RGB图像。图像以JPG格式存储，附带元数据，包含位置信息、相机参数及拍摄日期。

SHAPE模块：包含用于Agisoft Metashape软件中对点云、正射影像及数字高程模型（Digital Elevation Model, DEM）进行裁剪的形状文件（Shapefile），可清晰呈现葡萄种植行的可视化效果。

点云（POINTCLOUDS）模块：包含RGB、近红外（Near Infrared, NIR）、绿光（Green, G）、红边（Red Edge, RE）、红光（Red, R）及归一化差异植被指数（Normalized Difference Vegetation Index, NDVI）格式的原始点云和裁剪后点云。所有点云均通过Agisoft Metashape软件处理，以XYZ格式（.txt文件）存储。

正射影像（ORTHOMOSAICS）模块：包含RGB、NIR、G、RE、R及NDVI格式的原始正射影像与裁剪后正射影像。所有正射影像均由Agisoft Metashape软件生成，采用TIF格式存储。

数字高程模型（DEM）模块：包含原始数字高程模型与裁剪后数字高程模型，同样通过Agisoft Metashape软件处理，以TIF格式存储。

本数据集与Noumena（UC1）上传的其余UAV Canyelles葡萄园数据集对齐，因此可对不同日期的裁剪与未裁剪文件的正射影像、点云及数字高程模型进行联合分析。

本数据集于2024年5月10日在西班牙加泰罗尼亚坎耶莱斯采集。无人机以12米高度自动巡航，确保图像间具备充足的航向重叠度与旁向重叠度。
