A visual blind-guiding method is disclosed, which includes the following steps: (1) shooting a black-and-white image, and extracting profile information from the black-and-white image to reduce detail elements and refine the image, so as to obtain an object profile signal; (2) according to ergonomic features, converting the object profile signal into a serial signal, and conveying the serial signal to an image feeling instrument, where the image feeling instrument converts the serial signal into a mechanical tactile signal to emit feeler pin stimulation, an intermittent picture touch mode is used with respect to the speed of touch for vision, and an appropriate human-sensitive feeler pin array is adopted with respect to the quantity, so that the blind can really touch a shape of an object. |
