more specifically, a predetermined rule may be set for determining the vision level of the user.
The predetermined rules may include determining the user's vision level to be the vision level corresponding to the tagged test character 2331 when the user-entered direction matches the orientation of the tagged test character 2331.
Further, when the detection picture 231 includes 1-n lines of detection characters 232, where the m-th line of detection characters 232 includes a detection characters 232, m is greater than or equal to 1 and less than or equal to n, a is greater than 1, and m is a natural number, the predetermined rule further includes performing x on the m-th line of detection characters 2321A secondary label, and the number of times the user inputs the instruction information on the tape-label-check character 2331 is y when the instruction information input by the user matches the orientation of the tape-label-check character 23311And y is1/x1And when the vision level of the user is more than or equal to 50%, determining the vision level of the user as the vision level corresponding to the detection character 232 in the mth row.
Preferably, x is1Is odd, more preferably, x is1Equal to 3 or 5.
Preferably, in x1In the secondary identification process, the identified detection character 2331 is not repeated.
Further, the predetermined rule further includes x for the m +1 th line detection character 2322A secondary logo, and the user inputs indication information to the logo check character 2331, the number of times when the indication information input by the user matches the orientation of the logo check character 2331 is y2And y is2/x2Less than 50%, i.e., satisfying y simultaneously1/x1Not less than 50% and y2/x2If the vision level is less than 50%, the vision level of the user is determined to be the vision level corresponding to the m-th row detection character 232.
Preferably, x is2Is odd, more preferably, x is2Equal to 3 or 5.
At x2In the secondary identification process, the identified detection character 2331 is not repeated.
S17: writing the vision level of the user into a user database;
the vision detection system of the invention inquires the user information matched with the user basic information in the user database after inputting the user basic information, automatically generates the detection picture and generates the detection character with the identification, the user only needs to input the indication information, the system can determine the vision level of the user according to the direction and the indication information of the detection character with the identification, and automatically writes the vision level of the user into the user database, on one hand, the vision level is convenient for managing the user, on the other hand, the automatic detection on the vision and the automatic input of the detection result are realized, the vision condition of the user is convenient to track and monitor, meanwhile, the automatically generated detection picture can be flexibly adjusted to adapt to different detection requirements, such as an E table and a C table, and in addition, different detection pictures can be generated each time to prevent the user from influencing the detection result through.
In addition, the vision detection system can be arranged on a cloud server, or the data analysis and processing of a large number of users can be realized in modes such as big data analysis and cloud computing, so that higher value is realized.
In addition, other modifications within the spirit of the invention will occur to those skilled in the art, and it is understood that such modifications are included within the scope of the invention as claimed.
