5. The system of claim 4, wherein the determining vision data for the user from pupil images or eyelid images of both eyes of the user, performs the steps of:
determining the pupil diameter and diopter of the user according to the pupil image of the user;
determining blinking frequencies of the user from the eyelid image of the user;
determining a asthenopia state of the user based on the pupil diameter and blinking frequency of the user, the vision data comprising the diopter scale and the asthenopia state.
6. The system of claim 1, wherein the vision training system further comprises a timing unit communicatively coupled to the display module and the optics module, the timing unit configured to determine whether a cumulative time of movement of the display module and the optics module reaches a preset training time,
when the accumulated time of the movement of the display module and the optical module is less than the preset training time, the vision training control module controls the display module and the optical module to continue to move along the sight line direction of the user;
and when the accumulated time of the movement of the display module and the optical module reaches the preset training time, the vision training control module controls the display module and the optical module to stop moving.
7. The system of claim 1, wherein the vision training system further comprises a guiding unit for guiding the user's eye toward a plurality of preset positions,
and the vision training control module adjusts the preset position according to the maximum value in the comparison result between the vision data and the historical base values of the vision data.
8. The system of claim 1, wherein the optical module comprises: a stereoscopic optical unit, an image pickup unit, an a/D conversion unit, an image processing circuit, and an image output unit, wherein:
the stereoscopic optical unit is used for generating shot object images seen from a plurality of visual angles aiming at the same shot object;
the image pickup unit is used for generating stereo image data according to the shot object image generated by the stereo optical unit;
the A/D conversion unit is used for carrying out A/D conversion on the stereo image data generated by the camera shooting unit to generate digital stereo image data;
the image processing circuit is configured to perform image processing on the digital stereoscopic image data generated by the a/D conversion unit;
the image output unit module is used for outputting the stereo image data after the image processing is executed by the image processing circuit.
