Description
This dataset provides LiDAR-IMU sequences for evaluating odometry estimation performance in situations where LiDAR data becomes completely degenerated. A Livox Avia was used to record point cloud and IMU data, and the LiDAR was moved while facing to a flat wall. A camera rigidly attached to the LiDAR was used to observe visual fiducial tags (Apriltags) placed on the wall to measure the ground truth trajectory of the LiDAR.
