Portable traffic light distinguishing method for color blindness and color amblyopia people

Abstract

The invention discloses a portable traffic light distinguishing method for color blindness and color amblyopia people. When color blindness and color amblyopia people pass through an intersection provided with a traffic light, a rear camera of a portable device is aligned with the traffic light at the intersection first, and the position of the traffic light on a screen is determined by means of touching the screen with a finger; next, a traffic light recognition system of the device judges the color of the traffic light at the position determined by means of finger touching through a related algorithm of machine vision and digital image processing, and feeds back a recognition result to a user in the forms of screen text prompting and loudspeaker broadcasting at the same time. The portable traffic light distinguishing method has the advantages that color blindness and color amblyopia people are assisted in correctly judging the traffic light, and the defect that color blindness and color amblyopia people can only judge the traffic light according to the relative position of the traffic light is overcome; meanwhile, color blindness and color amblyopia people can also be helped greatly to judge color information quickly and correctly on other occasions.
