Distance Estimation Methods for Smartphone-Based Navigation Support Systems

Abstract

Distance estimation is a key element of a navigation system. Various methods and instruments are used in distance estimation procedures. The methods and instruments used usually depend on the contexts of the application area. This paper compares the accuracy of five practical distance estimation methods that can be used on portable devices. Some of the methods selected for this study have currently not yet been used in the context of navigation systems. The experimental results show that Rule 57 and AR based distance estimation methods hold great potential for the practical application of navigation support as they provide adequate accuracy and computational efficiency.
