Most of the previously proposed systems are based on global positioning system (GPS) sensors. However, the accuracy of low-cost versions is insufficient for pedestrian use. Furthermore, GPS-based systems are confined to outdoor navigation and experience severe signal losts in urban areas. This paper presents a new approach for localizing a person by using a single-body-mounted camera and computer vision techniques. Instantaneous accurate localization and heading estimates of the person are computed from images as the user progresses along a memorized path. A portable prototype has been tested for outdoor as well as indoor pedestrian use. Experimental results demonstrate the effectiveness of the vision-based localization: the accuracy is sufficient for making it possible to guide and maintain the blind person within a navigation corridor less than 1 m wide along the intended path. In combination with a suitable guiding interface, such a localization system will be convenient to assist the visually impaired in their everyday movements outdoors as well as indoors. <\/jats:p>","DOI":"10.1142\/s0219467810003937","type":"journal-article","created":{"date-parts":[[2010,12,6]],"date-time":"2010-12-06T09:10:55Z","timestamp":1291626655000},"page":"481-496","source":"Crossref","is-referenced-by-count":32,"title":["OUTDOOR\/INDOOR VISION-BASED LOCALIZATION FOR BLIND PEDESTRIAN NAVIGATION ASSISTANCE"],"prefix":"10.1142","volume":"10","author":[{"given":"SYLVIE","family":"TREUILLET","sequence":"first","affiliation":[{"name":"Institut PRISME, Universit\u00e9 d'Orl\u00e9ans Ecole Polytechnique, 12 rue de Blois, 47067 Orl\u00e9ans, France"}]},{"given":"ERIC","family":"ROYER","sequence":"additional","affiliation":[{"name":"LASMEA, Universit\u00e9 Blaise Pascal, Campus des C\u00e9zeaux, 63177 Aubi\u00e9re, France"}]}],"member":"219","published-online":{"date-parts":[[2012,4,30]]},"reference":[{"key":"rf3","doi-asserted-by":"crossref","first-page":"506","DOI":"10.1109\/IEMBS.1996.651838","volume":"2","author":"Makino H.","journal-title":"Proc.
