Embodiment 1

[0025] figure 1 It is a flow chart of a method for simulating visual impairment provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the method mainly includes the following steps:

[0026] Step 11, collecting images of real scenes.

[0027] Step 12. According to the type of visual impairment selected by the user, the corresponding algorithm is retrieved from the visual impairment simulation image algorithm repository, and the parameters of the algorithm are adjusted according to the severity of the disease.

[0028] In the embodiment of the present invention, the type of visual impairment selected by the user includes: one or more of myopia, hyperopia, astigmatism, higher order aberrations, amblyopia, cataract, and presbyopia. For example, images of myopia, hyperopia, and presbyopia can be simulated by Gaussian blur, and high-order aberrations can be simulated by changing the wavefront aberration.

[0029] Step 13: Process the image of the real sc...

Abstract

The invention discloses a visual impairment simulation method and device. The method comprises the following steps: acquiring an image of a real scene; calling a corresponding algorithm from a visual impairment simulation image algorithm storage library according to a visual impairment type selected by a user, and adjusting algorithm parameters according to corresponding severity of an illness; processing the image of the real scene according to the corresponding algorithm and the adjusted algorithm parameters; and displaying the processed image of the real scene to realize visual impairment simulation. Through adoption of the method and the device disclosed by the invention, the real scene image can be subjected to simulation processing, and the processed image can be displayed to the user in real time, so that the user can feel visual impairment more intuitively and really, and a better demonstration effect is provided.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a visual impairment simulation method and device. Background technique [0002] According to the "International Classification of Diseases-Tenth Edition" (updated and revised in 2006), the quality of vision can be divided into four grades: 1. Normal vision, 2. Moderate visual impairment, 3. Severe visual impairment, 4. Blindness disease. Worldwide, around 285 million people are visually impaired: 39 million are blind and 246 million are visually impaired. Among them, the number of visually impaired people in developing countries accounts for about 90% of the world. [0003] At present, there is no relevant technology for visual impairment simulation in the prior art, and users with normal vision cannot accurately and intuitively experience the feelings of patients with visual impairment. Contents of the invention [0004] The purpose of the present invention is to p...
