Low-vision head-mounted electronic auxiliary vision equipment and image modification method thereof

Abstract

The invention discloses low-vision head-mounted electronic auxiliary vision equipment and an image modification method thereof, the low-vision head-mounted electronic auxiliary vision device comprises a user input unit, at least one image capturing unit, a storage unit, a processing unit and a display unit, and images outside the visual field of a user captured by the at least one image capturing unit are marked as at least two external areas; the processing unit is configured to modify the image of any external area to form an image contour which can be displayed on the display unit in the field of view of a user, and the user input unit is configured to select the image contour of the external area required by the user to be displayed on the display unit in the field of view of the user. Compared with the prior art, the user can autonomously select the required image contour of the external area according to own needs and display the image contour on the display unit in the own visual field of the user, the visual-field-deficient user can intuitively operate the equipment to expand the visual field range of the visual-field-deficient user, and the life quality is improved.

Description

technical field [0001] The invention relates to the field of intelligent medical devices, in particular to a low-vision head-mounted electronic auxiliary vision device and an image modification method thereof. Background technique [0002] Low vision (low vision) usually refers to visual dysfunction that cannot be improved by surgery, drugs or general optometry, mainly including decreased vision and narrowed visual field. The causes of low vision vary greatly among different age groups. According to foreign data, among people under the age of 29, congenital eye diseases account for the vast majority of causes, and they are, in order, congenital ocular structural defects and nystagmus, congenital cataract, macular dystrophy, congenital optic nerve Atrophy, albinism, primary retinitis pigmentosa, post-lens fibrous hyperplasia, etc.; among people aged 30 to 59, they are optic atrophy, primary retinitis pigmentosa, diabetic retinopathy, macular dystrophy, Myopic retinopathy, e...

Problems solved by technology

[0005] In order to solve the technical problem that the low-vision head-mounted electronic visual aids in the prior art do not have the function of improving the field of vision, the purpose of the present invention is to provide a kind of field of view requirements for different low-vision users, which can be operated independently to realize the user's own field of vision. Head-mounted electronic aided vision device and image modification method in which scenery enters user's own visual field through image modification function
