Thermal and visible aerial imagery

Thermal and visible aerial images, with their metadata, captured using the UAV Matrice 100 equiped with a visible camera (Zenmuse X3) and a thermal camera (Zenmuse XT) of a planar scene at Universidad del Valle, Cali, Colombia. The thermal images were captured using the Zenmuse XT camera on board of a Matrice 100 UAV. Altitude = 100.4 m, Speed = 6.4 m/s and Overlap ratio = 90%. The visible images were captured using the Zenmuse X3 camera on board of a Matrice 100 UAV. Altitude = 80.9 m, Speed = 6.4 m/s and Overlap ratio = 80%. Also, a georeferenced orthoimage was generated using the captured visible images and the Agisoft Metashape software. In addition, homography matrices were obtained from a small number of correspondences manually selected between the orthoimage and every thermal and visible image. File "ORTHOUV2018.TIFF" = The georeferenced orthoimage. Folder "THERMAL" - Files "LWIRXX" = Thermal aerial images. - Files "HORTHOtoLWIRXX" = The homographies between the orthoimage and the thermal aerial images. - Files "LWIR.kml" = The geospatial data related to the thermal images. Folder "VISIBLE" - Files "VSXX" = Visible aerial images. - Files "HORTHOtoVSXX" = The homographies between the orthoimage and the visible aerial images. - Files "VS.kml" = The geospatial data related to the visible images.

本数据集包含热成像与可见光航空影像及其配套元数据，采集场景位于哥伦比亚卡利市德尔瓦尔大学（Universidad del Valle）的平面区域，采集所用平台为搭载可见光相机禅思X3（Zenmuse X3）与热成像相机禅思XT（Zenmuse XT）的经纬M100无人机（UAV，Unmanned Aerial Vehicle）。
热成像影像由搭载于经纬M100无人机的禅思XT相机采集，采集参数为：飞行高度100.4米，飞行速度6.4米/秒，影像重叠率90%。可见光影像由搭载于经纬M100无人机的禅思X3相机采集，采集参数为：飞行高度80.9米，飞行速度6.4米/秒，影像重叠率80%。
此外，本数据集还包含利用采集得到的可见光影像与Agisoft Metashape软件生成的地理配准正射影像。同时，通过在正射影像与每幅热成像、可见光影像间手动选取少量匹配点对，计算得到了对应的单应矩阵。
数据集文件与文件夹结构如下：
- 单文件"ORTHOUV2018.TIFF"：上述地理配准正射影像。
- 文件夹"THERMAL"：
- 命名格式为"LWIRXX"的文件：热成像航空影像
- 命名格式为"HORTHOtoLWIRXX"的文件：正射影像与热成像航空影像间的单应矩阵文件
- 文件"LWIR.kml"：与热成像影像相关的地理空间数据文件
- 文件夹"VISIBLE"：
- 命名格式为"VSXX"的文件：可见光航空影像
- 命名格式为"HORTHOtoVSXX"的文件：正射影像与可见光航空影像间的单应矩阵文件
- 文件"VS.kml"：与可见光影像相关的地理空间数据文件
