Snail Radar Dataset

4D radars are increasingly favored for odometry and mapping of autonomous systems due to their robustness in harsh weather and dynamic environments. Existing datasets, however, often cover limited areas and are typically captured using a single platform. To address this gap, we present a diverse large-scale dataset specifically designed for 4D radar-based localization and mapping. This dataset was gathered using three different platforms: a handheld device, an e-bike, and an SUV, under a variety of environmental conditions, including clear days, nighttime, and heavy rain.

Brief description

A dataset collected by 4D radars, stereo cameras, and lidars. The preprint paper describing the dataset is at arXiv.

Quick start

The dataset can be downloaded from either OneDrive or Baidu Netdisk(百度网盘) 提取码: 3141.

We provided zipped rosbags and zipped data folders.

The 44 sequences of our dataset are repeatedly collected at 8 places with three platforms in diverse weather/lighting conditions. The place shorthands bc=basketball court, sl=starlake, ss=software school, if=info faculty, iaf=info and arts faculty, iaef=info, arts, and engineering faculty, st=starlake tower, 81r=August 1 road. The platforms H=handheld, E=ebike, S=SUV. The weather and lighting condition is clear and daytime unless specified. Different to other sequences of the info and arts faculty, the 20240113/2 sequence's route is anticlockwise.

Usage

The source code to create the rosbags from the raw data and vice versa and the calibration data are available at here.
