To help the blind person walk independently ,an ETA system based on DSP (digital signal processor) was designed . The function and the basic structure of the system were introduced ,the hardware design and system software working process were described in detail .The system was based on the real‐time image processing ,which realized image acquisition ,processing , and voice prompt function without using the PC .Compared with the traditional equipment ,the guide precision is improved ,and compared with the large electronic system or global positioning system (GPS) ,the cost is saved .The small‐sized system is por‐table ,whose effectiveness is verified in the experiments .
