Fig. 11. GNSS/LiDAR integration final result: GNSS positioning based on WLS-NE without covariance estimation. The small circles represent the pose graph for further graph optimization. The colored points indicate the point clouds from the graph SLAM.

Fig. 12. GNSS/LiDAR integration final result: GNSS positioning based on WLS-NE with covariance estimation. The small circles represent the pose graph for further graph optimization. The colored points indicate the point clouds from the graph SLAM. The GNSS is integrated with LiDAR only when the covariance of GNSS positioning is less than 20 meters.

Fig. 8. Satellite numbers in top panel. Covariance estimation in button panel: The conventional covariance estimation is indicated in red dots. The proposed covariance estimation is indicated in blue dots. The GNSS positioning error using the WLS-NE is represented in black dots (ground truth for covariance).
