Color blindness detection method and device

Abstract

The invention discloses a color blindness detection method and device, and belongs to the technical field of detection. The method comprises the following steps: obtaining various preset color matching schemes, wherein each color matching scheme is used for detecting one type of color blindness, and each color matching scheme comprises accent colors and change colors; obtaining a color vision test pattern corresponding to each color matching scheme; when any one color vision test pattern is adopted to carry out a color blindness test on a tested person, according to a grid color change time sequence in the color vision test pattern, changing each grid in the color vision test pattern into the change colors from the accent colors one by one, and obtaining the eyeball position of the tested person when each grid changes colors; fitting an obtained color point movement track and an obtained eyeball movement track to obtain a first degree of fitting; according to the first degree of fitting, judging the color blindness type of the tested person. According to the method, the eyeball movement track of the tested person and the color point change track on the color vision test pattern are subjected to correlation analysis, the color blindness type of the tested person can be quantificationally analyzed, and color blindness detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a method and device for detecting color blindness. Background technique [0002] Color blindness is a kind of congenital color vision disorder. Color blind patients cannot distinguish various colors or a certain color in the natural spectrum; color blindness has poor ability to distinguish colors. Although color blind patients can see the colors that normal people see, they cannot recognize colors. The ability of the patient is slow or very poor. When the light is dark, some of them are almost as color-blind as patients, or show color vision fatigue. In people's production and life, especially in the fields of transportation, medicine, textile, instrumentation and art, if the color cannot be distinguished normally, it will bring great inconvenience. Therefore, color blindness detection has become a testing item for routine physical examination in my country. [0003] At presen...

AI Technical Summary

Problems solved by technology

When these methods are used for inspection, the subjects are extremely susceptible to interference from doctors and the external physical environment, so that the test results cannot quantitatively reflect the degree of color vision impairment of the subjects

And in many detection methods, due to the differences in the detection standards and methods themselves, the versatility and scientificity are poor

In addition, some color-blind patients will forcefully memorize the answers to the color vision test chart in order to pass the physical examination in order to obtain a motor vehicle driver's license or certain professional admission qualifications, etc., which will eventually cause adverse consequences
