Design and implementation of blind sidewalk recognition system based on FPGA

With the popularity of blind sidewalk construction in the city, the blind sidewalk can greatly facilitate the daily travel of blind man. However, in reality, some blind sidewalks often become disrepair, which is not convenient for the blind man to recognize. Some blind sidewalks are also occupied, which brings certain danger to the daily travel of the blind man. To solve this problem, this paper presents a video image blind identification system based on FPGA. The system uses Altera's DE2 development board as a hardware platform, and collects images through the CMOS image sensor, and realizes the real-time monitoring and recognition of the blind road environment, and provides voice prompts for the dangerous sidewalk sections.
