Tracking Systems: Calibration, Hardware, and Peripherals

Abstract

A single sensor that tracks the user’s pose is usually not sufficient for the creation of compelling augmented reality (AR) owing to system drift, noise, and tracking errors. Recent systems thus combine tracking information from multiple sensors, such as red green blue and infrared cameras, accelerometers, and depth sensors, to improve the illusion of an augmented world. In this chapter, we first introduce calibration methods, tracking sensors, and hardware that can track objects of interest, followed by a discussion of methods that can align the information gathered by these sensors.
