C3VDv2 - 结肠镜3D视频数据集
收藏资源简介:
C3VDv2是高清晰度结肠镜3D视频数据集的第二版,具有增强的现实性,旨在促进3D结肠重建算法的定量评估。数据集包括192个视频序列,由60个独特的、高保真度的硅胶结肠假体段成像捕获。为169个结肠镜视频提供了地面真实深度、表面法线、光流、遮挡、六自由度姿态、覆盖图和3D模型。数据集还包括由胃肠病学家获得的8个模拟筛查结肠镜视频,带有地面真实姿态。数据集还包括15个具有结肠变形的视频,用于定性评估。C3VDv2为3D重建算法模拟了多样性和挑战性的场景,包括粪便残渣、粘液池、血液、遮蔽结肠镜镜头的残渣、正面视图和快速摄像机运动。C3VDv2的增强现实性将允许更强大和更具代表性的3D重建算法的开发和评估。
C3VDv2 is the second edition of the high-definition 3D video dataset for colonoscopy, featuring enhanced realism and designed to facilitate the quantitative evaluation of 3D colon reconstruction algorithms. The dataset contains 192 video sequences captured by imaging 60 unique, high-fidelity silicone colon phantom segments. Ground-truth depth maps, surface normals, optical flow fields, occlusion masks, 6-degree-of-freedom (6DoF) poses, coverage maps, and 3D models are provided for 169 of these colonoscopy videos. Additionally, the dataset includes 8 simulated screening colonoscopy videos obtained by gastroenterologists, paired with ground-truth poses, as well as 15 videos with colon deformations for qualitative evaluation. C3VDv2 simulates diverse and challenging scenarios for 3D reconstruction algorithms, including fecal residues, mucus pools, blood, residues obscuring the colonoscope lens, frontal views, and rapid camera movements. The enhanced realism of C3VDv2 will enable the development and evaluation of more robust and representative 3D colon reconstruction algorithms.
