step three, photo synthesis: filling the pictures shot in the step two into the template selected in the step one according to the corresponding number positions through a picture filling module (21), watching the pictures, deleting unqualified pictures with poor shooting effects or because a patient does not watch the unqualified pictures of the observation lamp according to requirements, controlling the observation lamp (17) of the corresponding number position of the pictures to light up, shooting again until the pictures which accord with the corresponding number position information are obtained, blocking the left eye with an eye shield when the situation that two eyes in the pictures have obvious squinting for observation in different directions exists, repeating the operation of the step two and the step three through the right eye, obtaining the nine-eye pictures of the right eye with different visual angles, blocking the right eye with the eye shield, repeating the operation of the step two and the step three through the left eye, obtaining the nine-eye pictures of the left eye with different visual angles, then integrating the three groups of pictures in the same direction under different states into the nine-palace format picture filling template in the step one, namely, the left-eye picture and the right-eye picture are placed at the upper part and the lower part of the binocular picture in an equal scaling-down mode;

step four, information storage: the identity information and the diagnosis information of the patient are recorded into the correct picture template in the step three through the patient information importing module (22), and are imported into the information storage module (6) for storage after confirmation and storage.
