Embodiment 1

[0051] Such as figure 1 As shown, the stereoscopic induction method in the random element distribution background mode includes the following steps:

[0052] S1: Initialize the induction duration and set the time threshold;

[0053] S2: Set the background of random element distribution and several induced contours with distance relationship to build a stereoscopic visual space;

[0054] S3: Set the induced contour contrast and adjust the scale value according to the actual situation;

[0055] S4: In the case of increasing the induced contour, the observer observes the stereoscopic vision space to judge whether the hidden stereoscopic image can be stereoscopic and judge the distance relationship between the induced contours; if all judgments are correct, the induced contour is reduced according to the adjusted scale value Contrast; otherwise, increase the induced contour contrast according to the rescale value;

[0056] S5: Judging whether the induced contour contrast reache...

Embodiment 2

[0072] More specifically, on the basis of Example 1, such as Figure 4 As shown, the stereoscopic induction system under the random element distribution background mode is provided, including a processor and a human-computer interaction module, and the human-computer interaction module is electrically connected to the processor; in the processor, a Parameter preset module, random element distribution background generation module, random element distribution background selection module, induced contour generation module, contrast adjustment module, contrast judgment module, timer and stereo vision space construction module; wherein:

[0073] The parameter preset module is used to initialize the timer, that is, initialize the induction duration; set the time threshold, the initial induction contour contrast, the contrast threshold and the adjustment scale value;

[0074] The random element distribution background generating module is used to generate a random element distribution ...

Abstract

According to the stereo vision induction method in the random element distribution background mode, the contrast ratio of the induction contour is adjusted in real time according to the judgment of an observer within a certain time threshold value, and stereo vision of the observer under a certain contrast ratio can be repeatedly induced and stimulated; by setting the adjustment scale value, higher-precision induction of binocular stereoscopic vision can be realized; meanwhile, due to the arrangement of the distribution backgrounds of the random elements with different difficulty levels, the induction of stereoscopic vision with different levels can be realized, and the applicability is high. The invention further provides a stereoscopic vision guidance system in the random element distribution background mode. The stereoscopic vision guidance system includesa processor which is provided with a parameter presetting module, a random element distribution background generation module, a random element distribution background selection module, an induction contour generation module, a contrast adjustment module, a contrast judgment module, a timer and a stereoscopic vision space construction module, and a man-machine interaction module. The stereo-vision induction method is realized in a random element distribution background mode;.

Description

technical field [0001] The present invention relates to the technical field of stereopsis training, and more specifically, relates to a method and system for inducing stereopsis in a random element distribution background mode. Background technique [0002] The establishment process of human's visual three-dimensional sense is: two eyes look at an object at the same time, and the eyes of both eyes cross at one point, that is, the point of fixation, and the light points reflected from the point of fixation back to the retina correspond to each other. The center synthesizes a complete image of an object. Not only can you see this point clearly, but you can also distinguish the distance, depth, convexity, etc. between this point and the surrounding objects. The image formed in this way is a three-dimensional image. This kind of vision is also called stereoscopic vision. [0003] Stereo vision is clinically measured by two-dimensional visual targets. There are many types, some ...
