Embodiment Construction

[0047] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0048] figure 1 is a flowchart of a method for detecting a visual field defect according to an embodiment of the present invention. Such as figure 1 As shown, the method includes:

[0049] Step S110, displaying a standard image that matches the field of view of a specific user. For example, the standard image can be acquired by the user wearing glasses with a camera, or it can be stored in advance, and the standard image can be retrieved and displayed to the user when the visual field defect is detected. It is also possible, for example, for the user to wear glasses with a dis...

Abstract

The invention relates to the field of image processing, in particular to a method and device for detecting defects of visual field. The method comprises the following steps of displaying a standard picture, wherein the standard picture is matched with the view field of a specific user; receiving a tagging indication in accordance with a specific region in the standard picture; and tagging the specific region in the standard picture according to the tagging indication, wherein the specific region indicates the region of the defects of visual field. Through the adoption of the method and the device disclosed by the invention, an ordinary patient can be assisted to voluntarily detect the defects of visual field.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for detecting visual field defects. Background technique [0002] Augmented Reality (AR) technology is a technology that calculates the position and angle of an image in real time, superimposes corresponding images, videos, and 3D models on the image, and then fuses the virtual world with the real world. The AR client can perform real-time image recognition on the user's offline environment in combination with the image recognition materials directly stored locally, and display the location of the identified specific offline target in the real scene according to the pre-configured Enhanced performance displays the corresponding impression data. [0003] Defect of visual field refers to damage to the visual field. The field of vision is the vision outside the fovea of ​​the macula. Visual field defect is a medical condition that may indicate that the patient ...
