Full panorama images of 24 field plot centres during the expedition to Alaska, summer 2023@en

During an expedition to Alaska in summer 2023, full panoramic images of the sampled vegetation plots were captured for documentation purposes. The images were taken with a 360 camera (Samsung Gear 360) and from the centre 2-4 images recorded at the centre position of the vegetation plot standing at different positions. The images were stitched in the supplied software to 360x180 panorama images (7776x3888 pixels, 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.2023年夏季于阿拉斯加开展野外考察期间，为完成文档记录工作，研究人员对采样植被样地拍摄了全画幅全景图像。本次拍摄采用三星Gear 360全景相机，于植被样地中心的不同站位采集了2至4张图像。随后使用配套拼接软件将上述图像合成为360×180规格的全景图像，分辨率为7776×3888像素，格式为原始图像（raw images）。接着使用Hugin全景软件（Hugin Panorama Software，https://hugin.sourceforge.io/）对合成图像进行配准，并对图像中的人类及其他人工物体进行遮罩处理。最后通过GIMP的Resynthesizer插件（resynthesizer plugin，https://github.com/bootchk/resynthesizer）对最终全景图进行融合操作，修复图像中的缝隙与人类阴影瑕疵，并导出分辨率为7776×3888像素的单张全景图像。
