Voxel51/cholect50

CholecT50是一个关于腹腔镜胆囊切除术手术的数据集，标注了手术动作三元组。这是首个为手术视频提供动作三元组标注的公开数据集，支持细粒度手术活动识别的研究。数据集包含50个手术视频，每个视频帧都标注了形式为<器械, 动词, 目标>的动作三元组。具体包括7种器械（如抓取器、双极电凝器、钩子）、10种动词（如抓取、回缩、烧灼）和15种目标（如胆囊、胆囊管、肝脏）。数据集共计约100,000个标注帧，为手术视频理解模型的训练和评估提供了丰富的资源。

CholecT50 is a dataset of laparoscopic cholecystectomy surgeries, annotated with surgical action triplets. It is the first public dataset to provide action triplet annotations for surgical videos, enabling research in fine-grained surgical activity recognition. The dataset consists of 50 videos, with each frame annotated with action triplets of the form <Instrument, Verb, Target>. It includes 7 instrument categories (e.g., grasper, bipolar, hook), 10 verb categories (e.g., grasp, retract, cauterize), and 15 target categories (e.g., gallbladder, cystic duct, liver). The dataset contains approximately 100,000 annotated frames, providing a rich source for training and evaluating models for surgical video understanding.
