Abstract

The invention provides a head wearing type vision auxiliary system for patients with vision disorder. The head wearing type vision auxiliary system comprises a head wearing type glasses bracket which is used for installing and connecting each part of the system and facilitating a user to wear, a left eye display panel and a right eye display panel which are used for respectively displaying left and right eye images, two-path image collection equipment which is used for collecting the images according to the visual angle of human eyes, various sensors which are used for detecting the external environment and glasses states; a data processing center which is used for overall control of the system, image collection, processing and projection display, reception and processing of data of the sensors and implementation of related image processing algorithms, a matched image processing program which is designed for the patients with vision disorder and used for enhancing the vision of the patients, and a training and rehabilitation program which is designed for treating different vision diseases. The system provided by the invention can be used for collecting reality scenes in real time, and processing the collected images, the images are displayed in a method which is more accepted by the patients with vision disorder and the aim of vision assisting is fulfilled.

Description

technical field [0001] The invention relates to the technical field of visual aids, in particular to a head-mounted visual aid system for visually impaired patients. Background technique [0002] Visual impairment, also known as "visual disability", "visual defect", and "visual impairment", refers to partial or complete impairment of the structure or function of the visual organs (including eyeballs, ophthalmic nerves) and the optic nerve center of the brain due to various reasons. It is manifested by different degrees of visual impairment or narrowing of vision in both eyes, making it difficult to perform work, study and other activities that ordinary people can engage in, thus limiting or hindering normal functions that can be performed according to their age, gender, social and cultural conditions. [0003] According to the estimates of the World Health Organization, there are 40 million to 45 million blind people in the world, and the low-vision population is three times...
