Embodiment Construction

[0020] In order to make the solution of the present invention clearer and easier to implement, so as to highlight the advantages and objectives of the present invention, the implementation is described and illustrated in detail.

[0021] 101: Building an EEG platform

[0022] The composition of the ERP experimental platform includes: 2 high-performance computers, Neuroscan signal amplifier, three-dimensional display (stimulus presentation device), 32 conductive electrode cap (Ag-AgCl electrode, distributed according to the international 10-20 system), polarized three-dimensional glasses.

[0023] The stereoscopic display is a Changhong stereoscopic TV with a resolution of 1366×768 and a refresh rate of 60Hz, and uses E-prime2.0 to present image stimulation. The subjects were required to wear polarizing stereoscopic glasses and Neuroscan's 64 conductive electrode cap (impedance less than or equal to 5KΩ. The distance between the test subject and the display screen was 3 times t...

Abstract

The invention relates to an evaluation analysis method for three-dimensional viewing fatigue resulting from three-dimensional motion-in-depth. The method comprises the following steps of processing a test three-dimensional image material image, and enabling a target to carry out periodic reciprocating uniform motion in a parallax range of plus or minus 1 degree, wherein the uniform motion is divided into different motion speed levels; dividing subjective evaluation criteria to obtain score levels; analyzing subjective evaluation results of testees; measuring electroencephalograms of the testees before and after the testees view the three-dimensional motion-in-depth namely before and after fatigue, and extracting three basic frequency bands of eight brain regions; and carrying out comparison analysis on various brain region indexes under different fatigue situations, and comparing results with the subjective evaluation results, thereby obtaining the most effective electroencephalogram index for measuring the three-dimensional viewing fatigue resulting from three-dimensional motion-in-depth.

Description

Technical field: [0001] The invention relates to the field of stereoscopic image quality evaluation. Background technique: [0002] 3D TV can bring an immersive feeling and a better visual experience, the so-called 3D era has come. However, watching 3D TV for a long time will cause some physical or psychological symptoms: visual fatigue, dizziness, nausea, etc. [1]. In order to solve this problem, it is very necessary to find a suitable index to measure stereopsis fatigue. The traditional measurement method is to use subjective evaluation, mainly in the form of psychophysical method and questionnaire survey [2] [3]. the goal of. And the evaluation standards are not yet unified. Therefore, it is urgent to propose an objective index to measure stereopsis fatigue. The advantage of objective evaluation is that it is simple to operate and easy to implement. The disadvantage is that it is often far from the results obtained by subjective evaluation, cannot cover all three-dim...
