摘要

We present an application for mobile phones to detect indoor signs and help in localization. Because it depends only on device capabilities, it is flexible and unconstrained. Detection is accomplished online by keygraph matching between sign images collected offline and the image from a mobile camera phone. After detection we apply a simple localization method based on a comparison between the detected sign and a dataset, consisting of images of the whole environment taken at different positions. We show the results obtained using the application in a local indoor environment.
