PCN-TI 和 MVP-TI
收藏资源简介:
PCN-TI和MVP-TI数据集是基于现有的单模态点云补全数据集构建的多模态三元组数据集,包含点云、文本描述和投影图像。数据集大小为30974对文本和图像,旨在通过引入文本描述和投影图像来增强点云补全任务中的空间信息。数据集的创建过程包括对点云进行正交投影以生成投影图像,并通过简单的关键词替换生成文本描述,避免了复杂的预处理步骤。该数据集主要应用于点云补全任务,旨在解决点云数据在实际应用中由于遮挡、传感器限制等原因导致的缺失问题,提升点云补全的精度和效率。
PCN-TI and MVP-TI datasets are multimodal triple datasets constructed based on existing single-modal point cloud completion datasets, which contain point clouds, text descriptions and projected images. The dataset includes 30,974 pairs of text and image samples, aiming to enhance the spatial information in point cloud completion tasks by introducing text descriptions and projected images. The dataset construction process involves performing orthogonal projection on point clouds to generate projected images, and generating text descriptions via simple keyword replacement, thus avoiding complex preprocessing steps. This dataset is primarily applied to point cloud completion tasks, with the goal of addressing the missing issue of point cloud data caused by factors such as occlusion and sensor limitations in practical applications, and improving the accuracy and efficiency of point cloud completion.
