Alternatively, the controller 130 in the vision inspection apparatus 100 provided by the foregoing embodiment generates the i-th-level visually recognizable information and controls the display 110 to present the i-th-level visually recognizable information.

As shown in FIG. 1, the detection process of one cycle includes, but is not limited to, steps S101-S103:

s101: and acquiring the limb image information of the user aiming at the ith-level visual identifiable information.

Alternatively, the body image information of the user for the i-th visually recognizable information is acquired by the camera 120 in the vision detecting apparatus 100 provided in the foregoing embodiment, and is sent to the controller 130.

S102: determining whether the limb image information matches the ith-level visually identifiable information; if the visual identification information is matched with the visual identification information, generating and displaying i + 1-th-level visual identification information, and detecting in the next period until a detection end condition is met; and if not, generating and displaying the ith-level visual identification information and/or the (i-1) th-level visual identification information of the other direction, and carrying out detection of a subsequent cycle until a detection end condition is met.

Alternatively, the controller 130 in the vision detecting device 100 provided by the foregoing embodiment generates the detection result information corresponding to the current-stage visually recognizable information and controls the display 110 to present the detection result information.

Alternatively, the evaluation quality of the visually recognizable information may be a size of a character label, and the smaller the size of the character label, the more excellent the evaluation quality; conversely, the smaller the size of the character, the better the evaluation. The rating of the visually recognizable information may also be other discriminative ratings, such as: the density of the pattern lines, the similarity of the pattern color to the background color, and the like. Correspondingly, the thicker the pattern lines are, the better the evaluation quality is; the more similar the pattern color and the background color are, the more excellent the evaluation is.

According to the vision detection method provided by the embodiment, the visual identification information is displayed for the user, the limb image information of the user aiming at the visual identification information is acquired, and the vision detection result information is output according to the limb image information and the visual identification information and the analysis rule provided by the application, so that the machine detection mode of vision detection is favorably realized. The machine detection can replace the current manual vision detection, so that the cost of manual detection can be effectively reduced; the machine detection is beneficial to being realized by family electronic equipment or even personal portable electronic equipment, and has extremely low requirement on detection places, thereby effectively overcoming the problem of detection region limitation existing in manual detection, and the machine detection has high flexibility and strong interest, and the detection experience obtained by a user is better.

Optionally, the limb image information includes, but is not limited to: at least one of finger pointing information, arm pointing information, leg pointing information, and head pointing information. For example, the user bends the index finger, middle finger, ring finger, and small finger into a fist shape, and holds the thumb upright, and at this time, the direction of the thumb (left, right, upward, downward, or the like) is used as the direction information in the body image information.

In some possible embodiments, in the step S102, the ith-level visually recognizable information and/or the i-1-level visually recognizable information in another direction is generated and displayed, and the detection of the subsequent cycle is performed until the detection end condition is met, as shown in fig. 2, including but not limited to the steps S201 to S204:

Alternatively, another i-th-level visually recognizable information is generated by the controller 130 in the vision detecting device 100 provided by the foregoing embodiment, and the display 110 is controlled to present another i-th-level visually recognizable information. For example, the ith-level visually recognizable information is "E", another ith-level visually recognizable information is "", and the "E" is the same size as "".

S202: acquiring the image information of the other limb of the ith-level visually recognizable information of the user aiming at the other direction.

In this embodiment, after it is determined that the limb image information does not match the i-th level visual recognizable information, the i-th level visual recognizable information in the other direction is provided with the same evaluation goodness and badness, rather than immediately reducing the evaluation goodness and badness level of the visual recognizable information, which is beneficial to providing a user with a selection opportunity again, and can effectively reduce negative effects caused by invalid detection judgment due to user misoperation or failure of the vision detection device 100 to acquire the limb image information. And the times of unnecessarily reducing the evaluation quality level of the visual recognizable information are reduced, the vision detection period can be shortened, and the vision detection efficiency is improved.

In some possible embodiments, in the step S204, the i-1 th-level visually recognizable information is generated and displayed, and the detection of the next cycle is performed until the detection end condition is satisfied, as shown in fig. 3, including but not limited to the steps S301 to S303:

s301: visually recognizable information of level i-1 is generated and presented.

Alternatively, the controller 130 in the vision inspection device 100 provided by the foregoing embodiment generates visually recognizable information of the i-1 st level and controls the display 110 to present the visually recognizable information of the i-1 st level. For example, the ith-level visually recognizable information is "E", and the i-1 th-level visually recognizable information may be "E" or "" which is one size smaller than the ith-level visually recognizable information.

S302: and acquiring further limb image information of the user aiming at the i-1 level visual identifiable information.

Alternatively, the camera 120 in the vision inspection apparatus 100 provided in the foregoing embodiment acquires further limb image information of the user with respect to the i-1 st visually recognizable information and sends the further limb image information to the controller 130.

S303: if the image information of the other limb is determined not to be matched with the i-1 level visual identifiable information, determining whether the unmatched times reach the set times or not; and if the set times are reached, determining that the detection end condition is met.

Alternatively, the controller 130 in the vision testing apparatus 100 provided in the foregoing embodiment determines whether the image information of another limb matches the i-1 th visually recognizable information, and the controller 130 determines whether the number of mismatches reaches a set number of times, and if the set number of times is reached, the controller 130 also determines that the test end condition is satisfied.

In this embodiment, by determining whether the number of mismatches reaches the set number as a determination that the detection end condition is satisfied, it is possible to avoid excessive periodic detection, which is beneficial to saving resources of an execution device (e.g., the vision detecting device 100 provided in the foregoing embodiment).

Optionally, the unmatched setting times can be freely set according to needs, and the setting times can be automatically adjusted according to habits of users by using a machine learning technology.

In some possible embodiments, in the step S204, the i-1 th-level visually recognizable information is generated and displayed, and the detection of the next cycle is performed until the detection end condition is satisfied, as shown in fig. 4, including but not limited to the steps S401 to S403:

For example, the ith-level visually recognizable information is "E", and the i-1 th-level visually recognizable information may be "E" or "" which is one size smaller than the ith-level visually recognizable information.

S402: and acquiring further limb image information of the user aiming at the i-1 level visual identifiable information.

Alternatively, the controller 130 in the vision detecting device 100 provided by the foregoing embodiment generates the detection result information corresponding to the current-stage visually recognizable information and controls the display 110 to present the detection result information.

In another vision testing method provided in this embodiment, visually recognizable information and answer information for a user to select are displayed to the user, and after limb image information of the user for the visually recognizable information is obtained, it is first determined whether the limb image information is valid limb image information, that is, it is determined whether the limb image information can be mapped to the answer information and whether the mapped answer information meets a set time, so as to be used as a determination basis for determining whether the limb image information is valid limb image information. This is beneficial for providing a more diverse detection experience for the user.

For example, the user performs a corresponding body motion with respect to the visually recognizable information displayed by the display 110, the camera 120 captures the body motion and converts the body motion into body image information, the controller 130 receives the body image information and then controls the display 110 to display a corresponding cursor, and the user moves the body according to the position of the cursor displayed by the display 110 (the position of the cursor relative to the answer information) so that the cursor enters the selection frame of the answer information and keeps the set time, at this time, the controller 130 can determine whether the body image information is valid body image information, and continue the subsequent determination.

After confirming whether the limb image information is effective limb image information, outputting vision detection result information according to the limb image information and the visual identifiable information and the analysis rule provided by the application, thereby being beneficial to realizing a machine detection mode of vision detection. The machine detection can replace the current manual vision detection, so that the cost of manual detection can be effectively reduced; the machine detection is beneficial to being realized by family electronic equipment or even personal portable electronic equipment, and has extremely low requirement on detection places, thereby effectively overcoming the problem of detection region limitation existing in manual detection, and the machine detection has high flexibility and strong interest, and the detection experience obtained by a user is better.

Alternatively, the answer information may be a combination of information including a correct answer and at least one incorrect answer. For example, the visually recognizable information currently presented is "E" with the right opening, the answer information may include a correct answer "→" and a wrong answer "→", and of course, the wrong answer "←" and/or the wrong answer "↓" may be added to the answer information as necessary.

Alternatively, the answer information may be presented simultaneously with the visually identifiable information.

Optionally, the visually identifiable information is displayed first, and then the answer information is displayed. For example, the display 110 first presents the visually identifiable information for a period of time (e.g., 10 seconds), and then the display 110 presents only the answer information until the user selection is complete; alternatively, the display 110 may first display the visually recognizable information for a period of time, and then the display 110 may simultaneously display the visually recognizable information and the answer information until the user selection is completed.
