Abstract (in Japanese) (See Japanese page) 
(in English) When visually impaired people walk outside, they often encounter many challenges, such as acquiring information on the surrounding environment, recognizing their current location and even walking along the way. We propose a navigation and guidance system for the visually impaired integrating all the fundamental functions needed to support independent walking. It provides functions of route guidance and adjustment, zebra-crossing detection and guidance, pedestrian traffic signal detection and color identification, and entrance localization of the destination building. We conducted three experiments: zebra-crossing detection, pedestrian traffic signal detection, and entrance of a building's door detection. In the experiment that detected a zebra-crossing, the precision ratio was 0.77, and the recall ratio was 0.65. In the experiment that detected a pedestrian traffic signal, the precision ratio was 0.83, and the recall ratio was 0.76.
