Embodiment

[0031] The method for dynamic and static stereo vision test described in the embodiment of the present invention, such as figure 1 shown, including the following steps:

[0032] Step S1, the computer system receives the preset stereoscopic speed and parallax value, and generates a stereoscopic test image, and the stereoscopic test image includes a plurality of visual marks;

[0033] In the embodiment of the present invention, such as figure 2 As shown, the stereoscopic test image includes four visual targets, and the four visual targets are distributed on the upper, lower, left, and right sides of the stereoscopic test image. Each visual target is composed of a plurality of squares randomly distributed with random points, and the diameter of each visual target is The size is 1°, and the distance between the center of each optotype and the screen center of the computer system is 1.5°.

[0034] Among them, each optotype is composed of random distribution of multiple squares c...

Abstract

The invention relates to the technical field of computers, aims to solve the problem of low accuracy of an existing stereoscopic vision test method, and provides a dynamic and static stereoscopic vision test method and a terminal. The dynamic and static stereoscopic vision test method comprises the following steps: receiving a preset stereoscopic vision speed and parallax value, and generating a stereoscopic vision test image; receiving first test information, generating a first stereoscopic vision test result, if the first stereoscopic vision test result is qualified, adjusting the parallax value of the specified sighting target in a stepped manner, receiving second test information, and generating a second stereoscopic vision test result; and if the second stereoscopic vision test resultis qualified, controlling the parallax value of a specified sighting mark to be continuously increased from zero to a preset parallax value, adjusting the parallax value of the specified sighting mark to be zero, controlling the parallax value of the specified sighting mark to be continuously increased from zero to the preset parallax value, controlling all the sighting marks to move horizontallyin random directions in this way, ad receiving third test information; and generating a stereoscopic test result according to the first test information, the second test information and the third test information.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to a dynamic and static stereo vision test method and a terminal. Background technique [0002] Stereoscopic vision can be divided into static stereoscopic vision and dynamic stereoscopic vision according to whether the stimulus target contains motion information. Clinically, static stereoscopic examination is usually used to evaluate the patient's stereoscopic vision function, but objects in life are not always in a static state, such as driving a car , playing ball, and avoiding impact objects all rely on the dynamic stereoscopic function of the human eye. This depth perception formed by dynamic stimuli is dynamic stereoscopic vision. The relationship between dynamic stereopsis and static stereopsis is an issue we are interested in. In clinical practice, we often encounter some patients who are "stereoblind" through static stereopsis assessment and express that they stil...
