It uses only one camera, for example, the one of a mobile phone. Visual landmarks, such as frontal and lateral doors, stairs, signs, and fire extinguishers, are employed for localizing the user in the building and for tracing and validating a route for the user’s navigation. The developed system clearly improves the autonomy of persons with a very low vision during indoor navigation. © 2014, Springer-Verlag Berlin Heidelberg.engComputer vision and GIS for the navigation of blind persons in buildingsjournal articlehttps://dx.doi.org/10.1007/s10209-013-0338-8
