The invention discloses a wearable blind assisting system and method for converting an image into sound. The system comprises an image acquisition module, an image processing and audio conversion module and an audio output module. The image acquisition module is used for acquiring environmental information in a visual range of a user; the image processing and audio conversion module comprises an image processing unit and an audio conversion unit, the image processing unit is used for preprocessing the environment image, and the audio conversion unit is used for converting the preprocessed image into audio data, wherein the pixel points on different horizontal lines in the image correspond to different sound frequencies, and the pixel points with different brightness or the pixel points with different distances in the image correspond to different volumes; and the audio output module is used for playing the generated audio data. The wearable blind assisting system is simple in structureand convenient for the b
