Fit4CAD

Fit4CAD数据集由意大利国家研究委员会应用数学与信息技术研究所创建，包含225个高质量点云，每个点云通过采样CAD对象获得。数据集旨在评估和比较在点云中拟合简单几何原形的方法，特别关注平面、圆柱、圆锥、球体和圆环等几何形状。数据集已分为训练集和测试集，便于机器学习方法的使用。该数据集支持广泛的几何原形识别算法，旨在解决逆向工程中的数字模型重建问题，并推动形状检索、理解和压缩等领域的研究。The Fit4CAD dataset was developed by the Institute of Applied Mathematics and Information Technologies of the National Research Council of Italy. It contains 225 high-quality point clouds, each obtained by sampling CAD objects. The dataset is designed to evaluate and compare methods for fitting simple geometric primitives to point clouds, with particular focus on geometric shapes including planes, cylinders, cones, spheres, and tori. It has been split into training and test sets to facilitate the utilization of machine learning methods. This dataset supports a wide range of geometric primitive recognition algorithms, aiming to address the issue of digital model reconstruction in reverse engineering and promote research in fields such as shape retrieval, shape understanding, and compression.
