Seafloor images and raw context data along AUV track SO242/1_83-1_AUV10 (Abyss_196) during SONNE cruise SO242/1

The raw images (available on request) have been captured using a Canon 8-15mm fisheye lens and therefore they have a wide field of view, which results in a dark image boundary as the lights did not illuminate the outer sectors well. The images in this dataset have then been undistorted to virtual images that an ideal perspective camera with only 90 degrees horizontal field of view would have seen from the same position. To achieve this, the color of each pixel in the ideal image is obtained by […]本数据集的原始图像可按需获取，采用佳能（Canon）8-15mm鱼眼镜头拍摄，因此具备宽视场特性；由于光线未能充分照亮图像外围区域，最终成像存在偏暗的图像边界。随后，本数据集内的所有图像均被校正畸变，转换为等效于仅具备90°水平视场角的理想透视相机在同一拍摄位置所捕获的虚拟图像。为实现该转换，理想虚拟图像中每个像素的色彩值由[…]获取。
