This paper introduces an intelligent intersection crossing assist system for The Blind based on Freescale K60.On the basis of a detailed analysis of the needs of the blind man when they across the street, it use IAR6.3 development platform for programming, design based on hardware module based on Freescale K60 chip,detects whether there exist obstacles within a distance in front by means of ultrasonic and infrared and achieve zebra video image by OV7725 Hawkeye camera. The Laboratory test results show that the system could ensure that blind people can walk on the center of zebra and avoid obstacles, will be helpful to assist blind people to across the street.
