Photoacoustic conversion method, photoacoustic conversion system, photoacoustic conversion equipment and storage medium for blind people

The invention relates to the field of photoproduction conversion, in particular to a photoacoustic conversion method, system and device for the blind and a storage medium. Judging whether the blind person passes through the sidewalk or not based on the motion trail; if the blind person passes through the sidewalk, the position distance of the sidewalk closest to the blind person is obtained; judging whether the position distance is smaller than a preset distance or not; if the position distance is smaller than the preset distance, obtaining the color of a signal lamp; and based on the color of the signal lamp, acquiring sound information so that the blind can pass through the signal lamp based on the sound information. The sound information is generated according to the color of the signal lamp, and the blind can determine whether the signal lamp can pass currently according to the sound information, thereby guaranteeing the travel safety of the blind. And moreover, special intersections can be identified, an
