AI总结:

本文提出首个大规模真实场景RGB-D汽车数据集3DRealCar,包含2500辆汽车的高分辨率360度视图与点云,覆盖多品牌与三种光照条件,并验证了现有3D重建方法在反光和暗光场景下的局限性。

摘要:

3D汽车常用于自动驾驶系统、虚拟/增强现实和游戏中。然而,现有的3D汽车数据集要么是合成的,要么质量较低,限制了它们在实际场景中的应用,并与高质量的真实世界3D汽车数据集存在显著差距。在本文中,我们提出了首个大规模3D真实汽车数据集,称为3DRealCar,提供三个显著特征:(1) 高数量:使用智能手机精心扫描了2500辆汽车,获取了具有真实世界尺寸的汽车图像和点云;(2) 高质量:每辆汽车平均被捕捉为200个密集的高分辨率360度RGB-D视图,从而实现高保真3D重建;(3) 高多样性:该数据集包含来自100多个品牌的各种汽车,并在三种不同的光照条件下收集,包括反光、标准和暗光。此外,我们为每个实例提供了详细的汽车解析图,以促进汽车解析任务的研究。而且,我们移除了背景点云,并将汽车朝向标准化为统一轴,以实现仅针对汽车的重建和无背景的可控渲染。我们在3DRealCar中使用最先进的方法在不同光照条件下对3D重建结果进行了基准测试。大量实验表明,3DRealCar的标准光照条件部分可用于生成大量高质量的3D汽车,从而改进与汽车相关的各种2D和3D任务。值得注意的是,我们的数据集揭示了一个事实:最近的3D重建方法在反光和暗光条件下重建高质量3D汽车时面临挑战。我们的数据集在这里。

英文摘要:

3D cars are commonly used in self-driving systems, virtual/augmented reality, and games. However, existing 3D car datasets are either synthetic or low-quality, limiting their applications in practical scenarios and presenting a significant gap toward high-quality real-world 3D car datasets. In this paper, we propose the first large-scale 3D real car dataset, termed 3DRealCar, offering three distinctive features. (1) \textbf{High-Volume}: 2,500 cars are meticulously scanned by smartphones, obtaining car images and point clouds with real-world dimensions; (2) \textbf{High-Quality}: Each car is captured in an average of 200 dense, high-resolution 360-degree RGB-D views, enabling high-fidelity 3D reconstruction; (3) \textbf{High-Diversity}: The dataset contains various cars from over 100 brands, collected under three distinct lighting conditions, including reflective, standard, and dark. Additionally, we offer detailed car parsing maps for each instance to promote research in car parsing tasks. Moreover, we remove background point clouds and standardize the car orientation to a unified axis for the reconstruction only on cars and controllable rendering without background. We benchmark 3D reconstruction results with state-of-the-art methods across different lighting conditions in 3DRealCar. Extensive experiments demonstrate that the standard lighting condition part of 3DRealCar can be used to produce a large number of high-quality 3D cars, improving various 2D and 3D tasks related to cars. Notably, our dataset brings insight into the fact that recent 3D reconstruction methods face challenges in reconstructing high-quality 3D cars under reflective and dark lighting conditions. \textcolor{red}{\href{https://xiaobiaodu.github.io/3drealcar/}{Our dataset is here.}}
