Embodiment 1

[0059] refer to figure 1 , the embodiment of the present application provides a control method of a vision correction instrument, the method comprising:

[0060] Step 101, acquire the user's visual EEG data through the EEG signal acquisition module.

[0061] In the embodiment of the present application, the EEG signal acquisition module is a module installed on the VR head-mounted display device of the vision correction instrument, which includes EEG electrodes for contacting the user's scalp when the user wears the VR head-mounted display device To collect the user's EEG simulation signal. The EEG simulation signal is the electric wave change at the cerebral cortex when the user's brain is active. Usually, the human brain will generate electrophysiological activity on the surface of the cerebral cortex or scalp when performing specific activities or receiving specific stimuli.

[0062] And the embodiment of the present application just collects the user's EEG signal through...

Embodiment 2

[0073] refer to figure 2 , the embodiment of the present application provides another control method of a vision correction instrument, the method comprising:

[0074] Step 201, acquire visual EEG data based on the collected event-related potentials through the EEG signal acquisition module.

[0075] In the embodiment of the present application, event related potential (ERP, event related potential) is a user brain control signal that can well reflect the user's brain cognitive activity, and its acquisition process does not need to be like the steady state visual evoked potential (SSVEP , steady state visual evoked potential) is an incentive target that is set to flash at a certain frequency. At the same time, it does not require a lot of training like the motor imagery signal, which improves the accuracy of the lens position where the user's line of sight is clear.

[0076] Step 202, performing filtering and de-noising processing on the visual EEG data of the user.

Abstract

The invention provides a vision correction instrument control method, device and system and a computer storage medium, and relates to the field of data processing. The method comprises the following steps: acquiring visual electroencephalogram data of a user through an electroencephalogram signal acquisition module; obtaining a network average aggregation coefficient according to the visual electroencephalogram data of the user; when the network average aggregation coefficient is greater than a network average aggregation coefficient threshold, performing the step of obtaining the visual electroencephalogram data of the user; when the network average aggregation coefficient is smaller than or equal to the network average aggregation coefficient threshold, allowing a current lens position to be used as a lens position where the sight of the user is clear; and controlling the lens to move according to the lens position where the sight of the user is clear. According to a scheme of the invention, the vision correction effect of pseudomyopia can be improved; and meanwhile, invalid power consumption of the lens in a position range where the sight of the user is clear is avoided.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a control method of a vision correction instrument, a vision correction instrument and a computer storage medium. Background technique [0002] Pseudomyopia is a common type of myopia due to excessive use of the eyes that causes the continuous contraction of the ciliary muscle of the eye to spasm and increase the thickness of the lens. For this kind of pseudomyopia, the patient can restore normal vision by relaxing the eye muscles in time. However, if the patient ignores the false myopia for a long time, it may deteriorate into true myopia. [0003] In addition to dealing with some artificial myopia treatment methods for pseudomyopia in the prior art, a vision corrector based on VR (Virtual Reality, virtual reality) technology can also be used to train the patient's eyeball internal and external rotation ability to exercise eye muscles and correct vision. ...
