This paper proposes a solution using embedded system to provide navigation for the blind or visually impaired persons.Integrating with the high performance fix-point DSP ADSP-BF533 and video codec SAA7113,a hardware platform using as image processing is designed while recognition algorithms implemented on ported embedded operation system and optimizing methods are given.Results of experiment suggest that this system has good real-time property and recognition accuracy,which can serve the blind’s need for walking outdoors independently.
