Advanced Topic 45 of 49 Graphics, Vision & Media

SLAM

Building a map while tracking location simultaneously.

How it works

Simultaneous localization and mapping estimates a robot's pose while building a map from sensors (visual, LiDAR) using filters or graph optimization, with loop closure to correct drift.

Where it is used

Robots, AR, drones.

Common pitfall

Drift accumulates without loop closures.

Where it fits in the course

SLAM is topic 45 of 49 in Graphics, Vision & Media, rated Advanced. It follows Structure from Motion. The next topic is Augmented and Virtual Reality.
