A kind of hearing instead of vision's guide blind method relates to
electronic information field.The image of about 3 meters in front is collected by camera, and is sent into image to music module simultaneously to carry out image to music conversion, first, the image RGB space is converted to HSV space, and the value of each pixel point H, S, V is obtained.The value of H, S, V is mapped to the parameter of
midi format file of music, there are six mapping
modes, and the best mapping mode is that H value is given to the
pitch parameter of
midi file, S value is given to the volume parameter of
midi file, and V value is given to the
delta-
time parameter of midi file.The midi parameter construction is carried out by the obtained parameter value of midi file, and then the midi music file is obtained.The H, S, V value is matched with volume,
pitch and
delta-
time parameter after mapping, the converted music is obtained, the
human ear listens to this sound, judges the existence condition of the obstacle in front, and the purpose of guide blind is achieved.The hearing instead of vision
algorithm is realized by
programming, and cheap and effective assistance is provided for blind people.
