NTU4DRadLM
收藏资源简介:
NTU4DRadLM是由南洋理工大学电气与电子工程学院创建的多模态数据集,专注于定位与地图构建。该数据集包含6种传感器:4D雷达、热像仪、IMU、3D激光雷达、视觉相机和RTK GPS,适用于低速机器人和高速无人车辆。数据集覆盖了结构化、非结构化和半结构化环境,总长度约17.6公里,大小为50GB。创建过程中,数据集通过两种平台(手推车和汽车)在不同环境中收集,确保了数据的多样性和实用性。该数据集旨在解决在恶劣条件下(如雨、雪、烟雾和雾等)的SLAM问题,推动基于4D雷达、热像仪和IMU的SLAM研究。
NTU4DRadLM is a multimodal dataset developed by the School of Electrical and Electronic Engineering, Nanyang Technological University, focusing on simultaneous localization and mapping (SLAM). This dataset integrates six types of sensors, including 4D radar, thermal imager, IMU, 3D LiDAR, visual camera, and RTK GPS, and is suitable for both low-speed robots and high-speed unmanned ground vehicles. It covers structured, unstructured and semi-structured environments, with a total traversal distance of approximately 17.6 kilometers and a total file size of 50 GB. During the data collection phase, the dataset was gathered across diverse environments using two platforms: a mobile cart and a passenger car, which ensures the diversity and practicality of the collected data. This dataset is intended to address SLAM challenges under harsh conditions such as rain, snow, smoke and fog, and to promote SLAM research based on 4D radar, thermal imagers and IMUs.
