Abstract

The invention discloses a refractive information measuring method, which comprises the following steps of: acquiring a plurality of fundus images of a current to-be-measured human eye and shooting parameters of the fundus images; calculating the eye fundus image definition of the eye fundus image, and extracting a data point set of the eye fundus image according to the eye fundus image definition and the shooting parameters; inputting the extracted data point set into a prior model, and estimating corresponding model parameters in the prior model; and substituting the model parameters into a diopter calculation function to calculate refraction information of the human eyes. The invention also discloses a refractive information measuring device and a computer readable storage medium, and provides a refractive information calculation scheme based on a small number of fundus images with different definitions, and the refractive information is calculated in the currently collected small number of fundus images with different definitions. The refraction information of the human eyes is estimated and calculated according to the model parameters in the prior model, so that the image acquisition time is shortened, and the measurement precision of the refraction information of the eyes is also improved.

Description

technical field [0001] The invention relates to the technical field of fundus refraction measurement, in particular to a method, device and computer-readable storage medium for refraction information measurement. Background technique [0002] In recent years, the incidence of myopia has remained high worldwide. A number of research results have shown that the retinal peripheral refractive state may be related to the occurrence and development of central myopia. Accurate and rapid measurement and evaluation of peripheral refractive status with appropriate technology is the basis of in-depth research. At present, there are refraction measurement methods on the market, including retinoscopy optometry, window optometry and aberration measurement, but these methods are complicated to operate, take a long time to measure, and are time-consuming and labor-intensive. Moreover, in the process of measuring refractive information, since many images need to be taken, the exposure time...
