[0113] This embodiment provides a wearable blindness aid method that converts images into sounds, and the wearable blindness aid method that converts images into sounds includes:
[0114] S101. Collect environmental information within the user's visual range and preprocess the collected environmental images;
[0115] S102, converting the preprocessed image into audio data; wherein, in the audio data, pixels located on different horizontal lines in the environmental image correspond to different sound frequencies, pixels of different brightness in the environmental image or distances from preset reference points Pixels at different distances correspond to different volumes;
[0116] S103, playing the converted audio data.
[0117] Further, the above-mentioned conversion of the preprocessed image into audio data includes:
[0118] The preprocessed image is converted into left and right channel audio data by the following formula:
