Table 2.

Approaches to LIDAR-based localization. Examples of existing state-of-the-art algorithms corresponding to each approach are shown in the table. Approaches to 3D localization with a 2D map are not known to the authors, and therefore, this cell is greyed out.

	3D Localization	2D Localization
3D map	DLL, NDT-3D, AMCL3D	NDT-2D, AMCL
2D map	not possible	AMCL, NDT-2D
