| Outline of Final Research Achievements |
We developed systems to support the life activities of visually impaired people based on image processing. The research themes are as follows: (1) Development of white cane systems equipped with RGBD sensors: We developed systems that can recognize chairs, stairs, elevators, etc. using small and lightweight depth measuring sensors. (2) Development of object recognition methods using smartphones: We have developed recognition methods of escalators and restroom marks based on time-varying image processing and CNN, respectively. (3) Implementation of user experiments: The user experiments were conducted by blindfolded people to confirm the effectiveness of the proposed systems.

| Academic Significance and Societal Importance of the Research Achievements |
視覚障がい者を支援するシステムの開発は１９６０年代から行われているが，その多くは障害物を避けて歩くことのみが主眼で，周辺に存在する物体が何であるのか（例えば，椅子なのかドアなのか）を伝えることはできなかった．本研究で開発した支援システムは画像処理技術を使って環境中の物体を認識し，視覚障がい者に情報提供することができるので，その生活レベルの向上に貢献することができる．
