Abstract

Augmented reality is a technology-enabled interactive environment that enhances real-world environments with online objects coexisting in the same space, and has been applied to various fields including industry, medicine, personal assistance, and others. The purpose of this study is to develop an indoor guidance method based on augmented reality, using a smartphone. Such a method requires a simple algorithm in order to run its application using the limited resources available on a smartphone. In the study, two-dimensional online objects, for instance, directional arrows with texts, are superimposed onto inner building surfaces for guiding the user. Two methods, a perspective distortion correction method using the vanishing point in the scene and a stable vanishing point detection method, have been developed for simple registration of online objects. The vanishing point detection method have solved the common issue of slight jitter in the videos despite maintaining a fixed camera position by employing a particle filter.
