Image Recognition to Improve Positioning in Smart Urban Environments

Conference paper
Part of the Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering book series (LNICST, volume 318)


This paper describes a solution and algorithm to enhance positioning in outdoor environments with high buildings to be used in a mobile application to aid visually impaired people for navigation purposes. We used an image recognition algorithm and adjusted the android app algorithm to decrease the initial error average of 85 m (without any correction from GPS obtained signal) to a 5 m error, in the final version of our solution.
