Seafloor images and raw context data along AUV track SO242/1_88-1_AUV11 (Abyss_197) 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 […]

原始图像（按需提供）采用佳能8-15mm鱼眼镜头（fisheye lens）拍摄，因此具有宽视场，但由于光线未能充分照亮外围区域，导致图像边界较暗。本数据集的图像随后经过校正，转换为理想透视相机（perspective camera）（仅90度水平视场）从同一位置拍摄到的虚拟图像。为实现这一点，理想图像中每个像素的颜色通过[…]获得。
