该数据集是REAL-Colon的重新打包版本，专为流式自监督AF-SfMLearner训练设计。原始数据集基于CC BY 4.0许可发布。数据行从磁盘上提取的帧文件中采样，形成低帧率时间三元组；如果官方提取已进行子采样，则通过最近整数步长近似目标帧率，frame_stride记录每行前一张和当前图像之间的原始帧距离。REAL-Colon不提供深度或姿态真实值，因此深度、遮挡、姿态相关特征为null，且has_depth、has_occlusion和has_pose标志为false。数据集专注于内窥镜和结肠镜检查领域，适用于自监督学习任务。This dataset is a re-packaged version of REAL-Colon for streaming self-supervised AF-SfMLearner training. The original dataset is distributed under CC BY 4.0. Rows are lower-fps temporal triplets sampled from the extracted frame files that exist on disk. If the official extraction is already subsampled, the requested target_fps is approximated by the nearest integer step on that available frame grid. frame_stride records the actual original-frame distance between each rows previous and current image. REAL-Colon does not provide depth or pose ground truth, so depth, occlusion, pose_curr2prev, and pose_curr2next are null and has_depth, has_occlusion, and has_pose are false.
