In this lecture, we will take a look at some different localization methods. We distinguish between local and global methods.

Localization methods are grouped into two categories: Global and Local.

Global:

• Give a location with respect to the world
• Often inaccurate compared to local methods
• For example: GPS or Wi-Fi hotspots

Local:

• Give a location with respect to local sensor feedback
• Can be highly accurate compared to global methods
• For example laser scanner and on-board cameras
