The invention relates to various fields of deep learning algorithm, eye movement acquisition algorithm, intelligent data analysis, psychology and the like, in particular to an eye movement data acquisition method and an intelligent data analysis method.

Background

The mental disease includes not only a disease caused by congenital mental injury but also a mental disease caused by endocrine disorder, excessive stress, or the like. In the case of depression, mild depression does not appear to be largely independent of normal persons in daily life, but if uncontrolled and untreated, it may develop into major depression with hallucinations, delusions, etc., and its serious consequences are difficult to estimate.

With the rapid development and maturity of the stereo eye movement data acquisition method and the intelligent data analysis method, a suitable research tool is provided for the correlation analysis method of the eye movement data and the mental system diseases provided by the field.

Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings and examples.

As shown in fig. 1, the method for analyzing the correlation between the eye movement data and the mental system diseases specifically includes the following steps:

step 1: establishing a healthy control group sample as control group eye movement data, namely: recruiting healthy users to carry out a task video watching experiment (video shooting comprising a plurality of setting situations to achieve a diversity watching task, wherein each setting situation has psychological preference and mainly inspects mental diseases on one aspect) and recording eye movement data (shooting eyeball movement video), wherein the healthy users cover a wide age range and education degree, and the proportion of men and women is guaranteed to be 1:1 distribution as much as possible;

step 2: providing a 'visual field limitation' watching device with the same condition as that of a healthy contrast group for a test user, and acquiring a large amount of diverse eye movement data of the same test user through different types of watching 'tasks' set under various situations;

and step 3: performing multipoint positioning and standard eye shape conversion on both eye sockets by using a deep learning algorithm on eye movement data of all users under different situations, extracting pupils and irises by using a deep convolution neural network combining U-Net and Squeezenet, using the extracted information for reconstructing 3D eyeball information (simulation), finally combining with stereoscopic video content to realize real-time extraction of a fixation point and a sight line saccade track, and performing statistical classification on the extracted information (such as situation, a fixation area, fixation time, saccade time, a sight line track range and the like);

and 4, step 4: analyzing and comparing eye movement data of a test user under different situations with healthy control group data under the situations by using an intelligent algorithm (K-Means algorithm and SVM algorithm), determining the difference value and the proportion of the average gaze time (saccade time) of the test user and the healthy control group, confirming the matching degree of a gaze area and a sight line track of the test user and the control group, and finally outputting in the form of characters and pictures to provide visual eye movement data for doctors;

and 5: and establishing an intelligent enlarged sample system, and if the test user is finally confirmed to be healthy by a doctor, automatically classifying and uploading the eye movement data of the test user to a healthy control group data sample, so that the healthy control group eye movement data sample is enlarged, and a more reliable comparison task is provided for the next user.

And performing segmentation processing and fixation position extraction, extracting fixation time from the heat map obtained by the segmentation processing, and extracting fixation position labels according to the fixation positions.

The technology adopted by the invention mainly comprises a three-dimensional eye movement acquisition algorithm and an intelligent data analysis method. Through cooperation with professional medical experts, the invention designs a self neural disease analysis method, a user can carry out comfortable diagnosis under non-invasive conditions by participating in a task eye movement video experiment, videos set in multiple situations can give different psychological hints to the user, so that the user diseases are researched more specifically, the eye movement data of the user is compared and analyzed with health contrast group data through an intelligent data analysis system, the analyzed result is displayed by pictures and text contents, a doctor can conveniently and visually pre-diagnose the user, and finally, if the user is diagnosed as healthy, the system can automatically supplement user information to the health contrast group, and a wider health contrast sample is provided for the user to be detected next time.

The method combines the eye movement data acquisition method and the intelligent data analysis method, and provides a new objective method for the examination of mental diseases; in addition, through the application of the correlation analysis method of the eye movement data and the mental system diseases, doctors can have a preliminary judgment and understanding on own patients, so that the follow-up inquiry or treatment can be performed more specifically.
