“…Figure 11 shows the path generated by the exploration algorithm and the map generated by driving the path. The black dots and orange lines show the map generated by SLAM [12] and SLAM's position estimate when the LiDAR maximum distance is 50 m. The green dots and purple line show the map generated by SLAM and the SLAM's position estimate when the LiDAR maximum distance is 10 m. Both conditions are the result of adjusting only the maximum LiDAR range on the same dataset. We can see that the error is significant in situations where the sensor's performance is limited.…”

“…Hermann et al, (1977) first consider system observability in the control field. Nowadays, this theory is widely applied in many other fields (Wang et al, 2018;Lee et al, 2020). The observability matrix is computed and if the matrix rank is full, it indicates that the positioning system is observable.…”
