Problems solved by technology

[0006] The traditional measurement method of object image inequality is limited to measuring the regular difference in the horizontal and vertical meridian directions in the symmetrical image inequality, and the data and conclusions obtained from the measurement are relatively one-sided
It is difficult to make accurate qualitative and quantitative measurements of the object image difference in the oblique meridian direction, the image anisotropy with object image rotation, and the asymmetrical image anisotropy by the traditional image anisotropy measurement method, which makes some object images Unable to obtain accurate disease description and targeted treatment for patients

Abstract

The invention discloses an object image unequal measurement method based on a multi-control-point mode. The method comprises the following steps: 1), respectively presenting sighting mark graphs withthe same size and shape in front of a left eye and a right eye in a binocular split-view state, and placing four or more control points on each sighting mark graph; and (2) displacing the control points in a mode of dragging the control points until a detected person feels that all the control points in front of the left eye coincide with the control points at the corresponding positions in frontof the right eye; and calculating the displacement value of each control point to obtain an unequal image measurement result. Compared with a traditional image unequal measurement method, the method provided by the invention can measure object image size change rates and the object image rotation angles in multiple meridian directions.

Description

technical field [0001] The invention relates to the field of ophthalmology measurement, and more specifically, to a method for measuring object-image anisotropy based on a plurality of control points. Background technique [0002] Anisotropy between the two eyes is also known as anisotropy or binocular aberration in ophthalmology. This is when the retinal images of the two eyes are different in size or shape. The most advanced visual function of human beings is the binocular stereoscopic vision produced by the fusion of binocular object images in the visual center. The establishment of binocular stereoscopic vision depends on the aberration of the incoming object images of the two eyes. It is easier to fuse into a stereo image through the visual center. If the anisotropy of the two eyes exceeds the normal range, after the conduction enters the visual center, a series of visual and systemic symptoms will be caused according to the degree of difference between the two eyes. ...
