Kimera-Multi-Data: A large-Scale Multi-Robot Dataset for Multi-Robot SLAM
Description:
Platforms
We use a single set of camera intrinsic and extrinsic parameters for all the robots. The parameters follow the Kimera-VIO format and can be downloaded below.
Data format
The datasets are in compressed rosbag format. For best results, decompress the rosbags before usage.
rosbag decompress *.bagGround Truth
The ground truth trajectory is generated using GPS and total-station assisted LiDAR SLAM based on LOCUS and LAMP. The process is described in further detail in our paper. You can download the ground truth trajectory and reference point cloud below.
