Vision auxiliary method converting vision information to auditory information

Abstract

The invention provides a vision auxiliary method converting vision information to auditory information. The method includes steps of 1, performing image collection, namely, obtaining images of surrounding environment by using a binocular camera; 2, performing target extraction on obtained image information; 3, utilizing an image analyzing method for obtaining a spatial position (4) of an attention target; 4, utilizing a head-related transfer function for generating 3D sound image signals containing spatial position information of the target object. A blind person can recover the spatial information of the attention target through receiving the sound signals. The method can achieve an aim of helping blind persons avoid barriers in way and providing convenience for blind person travel.

Description

technical field [0001] The invention belongs to the field of machine vision, and in particular relates to a visual aid method for converting visual information into auditory information. Background technique [0002] 70% of the external information that humans come into contact with comes from vision. The loss of vision has caused extreme inconvenience to the life and work of these disabled people. Therefore, people have been working hard to study auxiliary methods to help them make a correct understanding of the surrounding living environment. Using technology to help the visually impaired to expand their ability to live independently and work has gradually become a topic that has attracted much attention. At present, the development of visual aids at home and abroad is still in its infancy, and the number of researchers involved in this field is relatively limited. Although some achievements have been made, its functions still have relatively large limitations. Commonly u...

Problems solved by technology

However, the OIC system can only convert images into sound signals. This method does not conform to human perception habits. Therefore, the invention converts the 3D position information of the target object into a sound signal, and the user judges the spatial position of the target object by listening to the sound signal.
