AI Technical Summary
Technical Problem
Existing EEG acquisition headbands lack positioning guidance during wear, leading to inaccurate electrode positioning, affecting the quality of EEG signal data, and requiring adjustment by others.
Method used
By acquiring facial images of the user, a 3D model of the head is created, the 3D points are determined and matched with the positioning points of the headband, and image and voice guidance is provided to help the user adjust the electrode position independently.
Benefits of technology
It enables non-professional users to independently and accurately position the EEG headband, reducing reliance on professionals and improving the accuracy of electrode positioning and the quality of EEG signal data.

Abstract
This invention provides a method and related device for wearing and positioning an EEG acquisition headband. The method includes: acquiring an initial facial image; establishing a three-dimensional head model based on the initial facial image; determining three-dimensional points based on the initial facial image, wherein the three-dimensional points are points on the three-dimensional model; acquiring point images based on the three-dimensional head model, wherein the point images are projection images of the three-dimensional model, the point images include target points, the target points correspond one-to-one with the three-dimensional points, and the target points and the three-dimensional points have a projection relationship; acquiring positioning points, wherein the positioning points are points on the headband; matching the three-dimensional points with the positioning points and acquiring matching information; and displaying the initial facial image and a guidance image based on the matching information.
