RGB and Thermal Drone Imagery over Forest Stand in Alberta, Canada

This dataset contains RGB (wide-angle) and thermal nadir images collected by a drone using an H20T camera. The data was collected on August 30,2022 over an 8 ha forest stand roughly 3.5km away from the Cynthia Hamlet in Alberta, Canada. The region is at an elevation of around 950m above sea level. Pine and aspen make up the majority of the tree species found within the images. More details about the camera can be found at https://www.dji.com/ca/zenmuse-h20-series/specs. There are 814 RGB images having dimensions 4056x3040 and 814 thermal images having dimensions 640x512, taken at the same time. The images are taken at a flight height of 120, and such that there is 75% side overlap and 80% front overlap between successive thermal images. The main purpose of this data is to perform orthomosaicing for the two modalities.本数据集包含由无人机搭载H20T相机采集的RGB（广角）与热红外天底视角图像。该数据集于2022年8月30日采集，采集区域为加拿大阿尔伯塔省距辛西娅村（Cynthia Hamlet）约3.5千米的一片8公顷林分，区域海拔约950米。图像所覆盖区域内的树木以松树与山杨为优势树种。该相机的详细参数可参考链接：https://www.dji.com/ca/zenmuse-h20-series/specs。本次采集同步获得了814幅尺寸为4056×3040的RGB图像，以及814幅尺寸为640×512的热红外图像。图像采集时飞行高度为120，相邻热红外图像的旁向重叠率为75%、航向重叠率为80%。本数据集的核心应用场景为两种模态图像的正射镶嵌（orthomosaicing）。
