Chapter 3. Tracking

Tracking refers to the dynamic determination of spatial properties at runtime.

In this chapter, we explain general characteristics of tracking and discuss various tracking technologies. We begin with stationary systems, continue with mobile sensors, and discuss optical tracking in detail. Finally, we give a brief introduction to fusion of tracking data from multiple sensors.
