Abstract

The invention discloses an eye diopter measurement device, the acquisition module is used to acquire the spot array image of the eye to be measured, and the first calculation module is used to calculate the horizontal vector and the vertical vector of the spot array image, which are respectively recorded as the first horizontal vector and the second A vertical vector, the second calculation module is used to construct the first matrix with the first horizontal vector and the first vertical vector, construct the second matrix with the second horizontal vector and the second vertical vector, and construct the third matrix, the third calculation module It is used to calculate the diopter of the eye to be tested according to the preset relationship satisfied by the third matrix and the diopter. The eye diopter measurement device disclosed in the present invention converts the image information into a matrix according to the obtained eye spot array image to be measured, and obtains the diopter information by calculating the matrix orthogonal transformation. Compared with the existing method, the calculation process of obtaining the eye diopter More simplified, which helps to improve measurement efficiency.

Description

Technical field [0001] The present invention relates to the field of eye detection, and in particular, to an eye diopter measuring device. Background technique [0002] The role of the eye refractive light is referred to as refractive. The eye is a visual organ that is adapted to the stimulus. From the optical angle, the eye can be seen as an optical system, the external object emits or reflects light, and after the eyeball will generate refraction, a clear reduction image is formed on the retina. However, the adjusted eyes will cause parallel light incident into the eyeball to the front or rear of the retina, thereby forming refractive. The refractive capacity of the eye is used to use diopter, and the refractiveness is the reciprocal of the distant distance of the eye. [0003] In the prior art, the method of measuring the eye diopter is to use the Sharkhartman wave pre-sensor to acquire the spot array image of the eye, map the spot array image to an ellipse, and obtain the ref...
