资源简介:
Fine-Grained VR Sketching Dataset, developed by SketchX at the University of Surrey and iFlyTek-Surrey Joint Research Centre, contains 1,497 pairs of 3D VR sketches and corresponding 3D chair shapes, showcasing large shape diversity. The dataset is designed to facilitate fine-grained analysis in the sketch community and expand it into the actively developing 3D domain. It emphasizes a convenient sketching scenario where sketches are sparse lines, requiring no prior skills or training, and is intended for applications such as fine-grained 3D shape reconstruction. The dataset is available for access to drive novel research insights and applications.
细粒度VR草图数据集(Fine-Grained VR Sketching Dataset)由萨里大学SketchX实验室与科大讯飞-萨里联合研究中心开发,包含1497组3D VR草图与对应的3D座椅模型,展现出丰富的形状多样性。该数据集旨在推动草图研究领域的细粒度分析,并将相关研究拓展至快速发展的3D领域。其聚焦便捷的草图绘制场景,所采用的草图为稀疏线条,无需任何前置技能或训练,可应用于细粒度3D形状重建等任务。该数据集对外开放获取,可为新颖的研究思路与应用开发提供支撑。

细粒度VR草图:数据集和洞察
数据集概述
- 名称: SkethchyVR
- 描述: 该数据集包含细粒度VR草图和相应的3D形状对。
- 可用位置:
- 数据集网页
- Google Drive (仅点云)
数据收集
- 收集工具: 使用名为SketchyVR的VR草图接口收集数据,参与者使用VR头盔和手柄如Oculus Rift进行沉浸式草图绘制。
数据处理
- 草图过滤: 过滤原始草图的演示脚本位于
tools/Filter original sketch.ipynb。 - 点云采样: 从过滤后的草图中采样点云用于训练,采样脚本位于
tools/gen_pointcloud.py。 - 点云渲染: 渲染点云文件的脚本位于
tools/vis_pc_mitsuba.py,需先安装MITSUBA并替换路径PATH_TO_MITSUBA2。
