Problems solved by technology

The disadvantage of this solution is that the changes of brightness and contrast make the text more obvious, but for some special low-vision groups, only the changes of brightness and contrast cannot get clear enough images

Abstract

The invention discloses a naked-eye three-dimensional display method for characters and aims to provide a method which can separate the characters from a background and output the characters to a naked-eye display device in a three-dimension manner. The method comprises the following steps of: (a) acquiring an image; (b) preprocessing the acquired image; (c) separating the characters from the background in the image; (d) vectorizing, magnifying and typesetting the separated characters; (e) generating a left-right-eye image by a binocular parallax method; and (f) generating an image which can be displayed by the naked-eye three-dimensional display device by interframe parity interleaving. Three-dimensional data with strong contrast can be acquired by the steps, so that all people with low vision can clearly see the displayed data. The method is suitable for all the people with low vision, such as presbyopia, astigmatism, amblyopia and the like.

Description

technical field [0001] The invention relates to a naked-eye three-dimensional display method for characters, in particular to a method for separating characters from a background and three-dimensionally outputting them to a naked-eye display device. Background technique [0002] People with low vision, especially those with amblyopia and presbyopia, have various degrees of obstacles when reading ordinary printed materials such as books and newspapers. However, traditional magnifying glasses, reading glasses and other products have insufficient magnification, poor clarity, and text edge recognition. Difficulty, edge deformation and other problems have seriously affected the reading activities and daily life of people with low vision. However, the existing technologies are often based on optical performance forms, or simple two-dimensional magnification devices, which cannot be coordinated with users' real-time reading, and the speed, clarity, and text edge recognition effects...
