Embodiment 1

[0131] The following takes the data collection and processing of a certain tester as an example to illustrate the implementation process of this method. After selecting a certain tester for data collection, first let him wear an eye tracker and adjust the equipment to a normal working state. The experiment time is three minutes. In a natural state, the eye movement data for this period of time is continuously collected.

[0132] Perform the various preprocessing described in step S201 on the eye image collected at a certain moment, including image processing such as grayscale, denoising, and histogram equalization, to obtain Image 6 The image of the preprocessing result shown in (a) is obtained after edge detection Image 6 Figure (b). Then perform the ellipse fitting described in step S202 above on the edge part of the image in (b) to obtain an elliptical eye image, such as Image 6 (C) shown in the figure.

[0133] After obtaining the elliptical eye image, the eyelid distance me...

Abstract

The invention relates to a glasses wearing comfort evaluation method based on an eye movement technology. The method comprises the following steps: acquiring eye movement data and eye pictures of a subject within a period of time, processing the acquired eye images to calculate eyelid spacing abnormal time percentage and blinking frequency, and establishing a multiple linear regression model according to the eyelid spacing abnormal time percentage and the blinking frequency to judge the comfort degree of the glasses. According to the invention, through a large amount of subjective sampling andexperiments, the influence of eyelid spacing and blinking frequency on the wearing comfort of glasses is quantitatively studied. A sample database and a multivariate linear regression model are established, a comfort judgment score interval is obtained. A quantitative standard is provided for subsequent glasses wearing comfort judgment, and then a multivariate linear regression model can be obtained according to the multivariate linear regression model.

Description

Technical field [0001] The invention relates to a method for evaluating the wearing comfort of glasses, in particular to a method for evaluating the wearing comfort of glasses based on eye movement technology. Background technique [0002] Eye movement technology is a technology that analyzes and studies the individual's inner cognitive experience by recording the changes in the eye movement trajectory while extracting data such as fixation point, fixation time, blinking time, and pupil position. An eye tracker is an instrument that uses eye movement technology to record various eye movement characteristics of people when processing visual information. Since the 1960s, with the rapid development of camera technology, infrared technology and microelectronics technology, especially It is the application of computer technology that has promoted the research and development of high-precision eye trackers and greatly promoted the application of eye movement research in various discipl...
