Full panorama images of 16 field plot centres during the expedition to Alaska Interior and the southern Seward Peninsula, summer 2024

During an expedition to Alaska Interior and the southern Seward Peninsula in summer 2024, full panoramic images of the sampled vegetation plots were captured for documentation purposes. The images were taken with a 360 camera (Insta360 R, 1 inch sensor) from the centre of the vegetation plots. At each, three images were recorded holding the camera at a fixed position at breast height (1.3 m above ground) standing at different positions. The images were stitched in the supplied software to 360x180 panorama images (6528x3264, raw images). These were aligned in Hugin Panorama Software (https://hugin.sourceforge.io/) and humans or other artificial objects masked. The final panorama was blended and gaps or human shadow errors healed with GIMP resynthesizer plugin (https://github.com/bootchk/resynthesizer) and exported into one image with 7776x3888 pixels.2024年夏季，研究团队在阿拉斯加内陆及苏厄德半岛南部开展科考活动期间，为记录所采样的植被样地，拍摄了全景影像。本次拍摄采用搭载1英寸传感器的Insta360 R型360°全景相机，所有影像均采集自植被样地的中心位置。每个样地均将相机固定于胸高（距地面1.3米）位置，在三个不同站位分别拍摄三张影像。所拍摄影像将通过配套软件拼接为360×180度全景影像（分辨率6528×3264，原始格式）。随后使用Hugin全景软件（Hugin Panorama Software，https://hugin.sourceforge.io/）对拼接得到的影像进行配准，并通过掩膜操作移除人类及其他人工物体。最终借助GIMP的Resynthesizer插件（https://github.com/bootchk/resynthesizer）对全景图进行融合处理，修复画面间隙及人影瑕疵，并导出为分辨率7776×3888像素的单张最终影像。
