Problems solved by technology

However, the covering method often causes amblyopia in the healthy eye on the opposite side of the amblyopia due to long-term covering and affects the stereoscopic vision and fusion function of both eyes.
[0004] The existing image processing method is for a single image, and does not have the function of processing the same image into different levels of display content according to the characteristics of both eyes. Therefore, it cannot be applied to VR application scenarios where the physiological parameters of the eyes are different.
[0005] On the other hand, the traditional image processing method does not have the characteristics of parameterized continuous adjustment of the image processing effect, so it cannot adapt to the fine-tuning ability under different eye conditions, so it cannot be effectively applied in the field of eye medicine

Embodiment 1

[0052] The individual adjustment of embodiment 1 color

[0053] Specific steps are as follows:

[0054] 1. Obtain eye parameters

[0055] 2. Obtain the value of each pixel of the image (there are many ways to express the color of pixels, the calculation method below uses RGB expression as an example)

[0056] 3. Calculate the value of each pixel, as follows:

[0057] According to the configuration parameters of the left and right eyes, the color intensity of the image is adjusted, so that the color intensity of the image received by the left and right eyes is different. The specific process is to perform pixel-level calculation on the image so that the image presents different color effects according to different parameters, the method is as follows:

[0058] The input parameter is the information intensity parameter percentage P of the left and right eyes ([0, 1] range)

[0059] Its characteristic is that when P is 1, the image has the original color presentation, when P ...

Embodiment 2

[0069] Individual adjustment of embodiment 2 contrast

[0070] Specific steps are as follows:

[0071] 1. Obtain eye parameters

[0072] 2. Get the value of each pixel of the image

[0073] 3. Calculate the value of each pixel, as follows:

[0074] According to the configuration parameters of the left and right eyes, the contrast intensity of the image is adjusted, so that the light and dark intensity of the image received by the left and right eyes are different. The specific process is to calculate the pixel level of the image so that the image can show different brightness effects according to different parameters. The method is as follows:

[0075] The input parameter is the information intensity parameter percentage P of the left and right eyes ([0, 1] range)

[0076] Its feature is to use the P value to redistribute the color gamut of the image. The larger the P value, the more obvious the color contrast of the image, and the smaller the P value, the corresponding re...

Embodiment 3

[0081] Embodiment 3 Individual adjustment of image size

[0082] Specific steps are as follows:

[0083] 1. Obtain eye parameters

[0084] 2. Get the value of each pixel of the image

[0085] 3. Calculate the value of each pixel, as follows:

[0086] According to the configuration parameters of the left and right eyes, the size of the image is adjusted, so that the size of the image received by the left and right eyes is different.

[0087] The input parameter is the information intensity parameter percentage P of the left and right eyes ([0, 1] range)

[0088] Its characteristic is that the larger the P value, the larger the image area, and the smaller the P value, the smaller the image area. When P is 1, the image has the original size, when P is 0, the image area is 0, and when P is an intermediate value, the effect of the image changes linearly.

[0089] This method adopts the interpolation method to carry out the scaling calculation of the image, and its process is a...

Abstract

The invention provides a parameter processing method of a 3D image system for treating amblyopia, the 3D image system and a device. A 3D image includes a left parallax image and a right parallax imagerespectively corresponding to the left eye and the right eye of a human body, wherein the left eye only can see the left parallax image; the right eye only can see the right parallax image; and parameters of the left parallax image and the right parallax image are separately adjusted independently according to requirements of users. By means of the parameter processing method provided by the invention, parameter change of the left parallax image and the right parallax image of the 3D image is not limited any longer; according to own characteristics of amblyopia patients, the size, the brightness, the gray level, the colour saturation and the contrast ratio of all or part pictures of left and right screens can be freely adjusted; amblyopia eyes can be sufficiently trained and treated in atargeted manner; and furthermore, health eyes can be protected.

Description

technical field [0001] The invention belongs to the field of medical equipment and image processing, and relates to a parameter processing method of an image system for treating amblyopia. Background technique [0002] Amblyopia is a common eye disease in children in ophthalmology. It is a state of visual function decline that occurs in infants and young children when they fail to receive appropriate visual stimulation due to various reasons such as perception, movement, conduction, and visual center, which affects visual development. , mainly manifested as low vision and binocular single vision dysfunction. [0003] The common treatment method for treating amblyopia is covering method, which is divided into complete and partial covering. The purpose is to cover the good eye and force the weak eye to focus and perform fine work. However, the covering method often causes amblyopia to occur in the healthy eye on the opposite side of the amblyopia due to long-term covering an...
