R3ST (Realistic 3D Synthetic Trajectories)
收藏资源简介:
R3ST是由罗马大学团队开发的合成3D数据集,旨在为交通分析和轨迹预测研究提供高质量数据支持。该数据集包含超过8万帧的合成图像,涵盖多种城市交叉路口场景,并集成了来自真实无人机航拍数据(SinD数据集)的车辆轨迹。数据集通过Blender构建虚拟环境,采用真实轨迹驱动车辆运动,同时提供实例分割、深度图和边界框等多模态标注。其创新之处在于将合成数据的可控性与真实人类驾驶行为相结合,主要应用于自动驾驶模型训练、轨迹预测算法评估和智能交通系统研究。
R3ST is a synthetic 3D dataset developed by the research team at Sapienza University of Rome, designed to provide high-quality data support for traffic analysis and trajectory prediction research. This dataset contains over 80,000 frames of synthetic images covering various urban intersection scenarios, and integrates vehicle trajectories sourced from real drone aerial photography data (the SinD dataset). The virtual environment is built using Blender, with vehicle movements driven by real trajectories, and it also provides multi-modal annotations including instance segmentation, depth maps and bounding boxes. Its core innovation lies in combining the controllability of synthetic data with real human driving behaviors, and it is mainly applied to autonomous driving model training, trajectory prediction algorithm evaluation and intelligent transportation system research.

数据集简介
R3ST是一个合成3D数据集,旨在通过生成合成3D环境并集成从真实无人机镜头记录的鸟瞰数据集SinD中提取的真实世界轨迹,来弥补合成数据与真实轨迹之间的差距。该数据集推进了道路车辆轨迹预测的研究,提供了准确的多模态真实标注和真实的人类驾驶车辆轨迹。
核心特点
- 真实轨迹:与通常由AI驱动或基于规则的算法决定车辆运动的典型合成数据集不同,R3ST集成了源自SinD数据集(一个具有从真实无人机镜头提取的精确车辆位置标注的鸟瞰数据集)中两个场景的真实世界车辆轨迹。
- 合成环境:通过使用Blender渲染创建的虚拟交叉口生成。
- 多模态标注:利用Vision Blender计算额外的多模态标注,可用于一系列计算机视觉应用。同时,直接从Blender世界环境中导出场景中每个对象的3D边界框,并将其投影到图像平面上以获得2D边界框。
应用与评估
- 主要应用:用于训练和评估用于交通分析及提高道路安全的计算机视觉模型,特别是在轨迹预测领域。
- 标注类型:提供实例分割和单目深度估计的定性结果示例。实例分割结果使用YOLO-Seg和SAM2在线演示获得,单目深度估计使用在KITTI上预训练的AnyDepth和Pixelformer Large执行。

Existing real datasets fit real-world scenarios, capturing authentic road object behaviors, however, they typically lack precise ground-truth annotations. In contrast, synthetic datasets play a crucial role, allowing for the annotation of a large number of frames without additional costs or extra time. However, a general drawback of synthetic datasets is the lack of realistic vehicle motion, since trajectories are generated using AI models or rule-based systems. In this work, we introduce R3ST (Realistic 3D Synthetic Trajectories), a synthetic dataset that overcomes this limitation by generating a synthetic 3D environment and integrating real-world trajectories derived from SinD, a birds-eye-view dataset recorded from drone footage. The proposed dataset closes the gap between synthetic data and realistic trajectories, advancing the research in trajectory forecasting of road vehicles, offering both accurate multimodal ground-truth annotations and authentic human-driven vehicle trajectories.
