step 101: and presetting optotypes with different ideal distances and different sizes corresponding to different preset vision grades in the wearable equipment.
Different preset vision grades correspond to different ideal distances and visual targets with different sizes. For example: the ideal distance corresponding to 5.0 vision is 0.5m, the corresponding optotype size is A, the ideal distance corresponding to 4.0 vision is 0.4m, and the corresponding optotype size is B. The ideal distance is not particularly limited by the embodiments of the present invention.
Step 102: and determining the vision grade tested by the user so as to determine the ideal distance corresponding to the preset vision grade.
Step 103: and under the condition that the user performs vision test, outputting and displaying a visual target with the size corresponding to the preset vision grade in a screen of the wearable device.
The scaling relationship of the optotypes is shown in fig. 2.
The preset vision level may be preset in the wearable device by the user, where the preset vision level may be set to 5.0, 4.0, and 3.0, and this is not particularly limited in the embodiment of the present invention.
Step 104: an actual distance of the user from a screen of the wearable device is determined.
The actual distance between the user and the screen of the wearable device can be measured based on distance measuring devices such as ultrasonic distance measuring devices, infrared distance measuring devices, laser distance measuring devices and the like.
The infrared distance measuring sensor is a sensing device, is a measuring system using infrared rays as a medium, and has the advantages of wide measuring range and short response time. The infrared distance measuring sensor is provided with a pair of infrared signal transmitting and receiving diodes, a beam of infrared light is transmitted by the infrared distance measuring sensor LDM301, a reflection process is formed after the infrared distance measuring sensor LDM irradiates an object, the infrared distance measuring sensor LDM reflects the infrared distance measuring sensor LDM to the sensor and receives signals, and then data of time difference between transmitting and receiving are received by CCD image processing. The distance of the object is calculated after being processed by the signal processor.
Ultrasonic waves are often used for measuring distances because of strong directivity, slow energy consumption and long propagation distance in a medium, and for example, a distance meter, a level meter and the like can be realized by ultrasonic waves. The ultrasonic detection is often relatively rapid and convenient, the calculation is simple, and the real-time control is easy to realize.
Laser distance measuring (laser distance measuring) measures distance using a laser as a light source. And are classified into a continuous laser and a pulse laser according to the way the laser operates. Helium neon, argon ion, krypton cadmium and other gas lasers work in a continuous output state and are used for phase type laser ranging; the double heterogeneous gallium arsenide semiconductor laser is used for infrared distance measurement; solid lasers such as ruby and neodymium glass are used for pulse type laser ranging. The laser range finder not only can work day and night but also can improve the range finding precision compared with a photoelectric range finder because of the characteristics of good monochromaticity, strong directivity and the like of laser and the integrated electronic circuit.
Step 105: and measuring the sight line distance between the eyes of the user and the depth-of-field camera through the depth-of-field camera.
Depth of field camera and range unit set up the upper end and the lower extreme at wearable equipment to can detect user's line of sight distance and actual distance.
Step 106: and under the condition that the line-of-sight distance is not equal to the actual distance, outputting second prompt information for adjusting the line-of-sight distance.
Fig. 3 is a schematic diagram showing the line-of-sight distance and actual distance test. 1 is the depth of field camera, 2 is the range unit, and 3 is the user's eye position. The method comprises the steps of determining a face image of a user through a depth-of-field camera, identifying the positions of eyes in the face image of the user, and determining the linear distance between the positions of the eyes and the depth-of-field camera as the line-of-sight distance of the user.
When the line of sight distance equals to the actual distance, or line of sight distance + error parameter equals to the actual distance approximately, then can confirm that user's sight is perpendicular with wearable equipment's screen, and the eyesight test is more accurate.
And when the line-of-sight distance is greater than the actual distance, the fact that the line of sight of the user is not perpendicular to the screen is indicated, second prompt information for adjusting the line-of-sight distance is output, and the user moves the arm upwards or downwards based on the second prompt information to adjust the line-of-sight distance to be equal to the actual distance.
In a specific implementation manner of the present invention, the step 106 may include:
substep A1: and under the condition that the line-of-sight distance is not equal to the actual distance, determining a second adjusting parameter according to the actual distance and the line-of-sight distance.
Substep A2: and generating and outputting second prompt information according to the second adjusting parameter.
For example: and determining that the sight line distance between the sight line of the user and the screen is 70cm, outputting prompt information for moving the arm when the ideal distance is 50cm, and adjusting the arm by the user so as to adjust the sight line distance and monitor the relation between the sight line distance and the ideal distance in real time to ensure that the sight line distance is equal to the ideal distance.
Step 107: and outputting first prompt information for adjusting the distance under the condition that the ideal distance is not consistent with the actual distance.
Under the condition that the ideal distance is inconsistent with the actual distance, determining a first adjustment parameter of the actual distance according to the ideal distance; and generating and outputting first prompt information according to the first adjusting parameter.
For example: the distance between the user and the screen of the wearable device is 0.55m, the ideal distance corresponding to the preset eyesight is 0.5m, and then a first adjustment parameter is generated according to the ideal distance and the actual distance, wherein the first adjustment parameter is 0.05m moving towards the direction close to the screen.
The first reminder message may be "move 0.05m in the direction of the screen of the wearable device. "
Step 108: and adjusting the actual distance to be consistent with the ideal distance according to the first prompt information.
And the user adjusts the actual distance between the user and the screen based on the first prompt message.
Step 109: the adjusted distance is compared to the ideal distance.
Step 110: and outputting prompt information with proper distance under the condition that the adjusted distance is consistent with the ideal distance.
And after the user adjusts the distance between the user and the screen, determining the actual distance between the user and the screen again, and outputting prompt information with proper distance under the condition that the actual distance is consistent with the ideal distance.
Step 111: the vision of the user is determined.
In a specific implementation manner of the present invention, the step 111 may include:
substep C1: and receiving vision test instructions input by a user.
Substep C2: and determining the vision of the user according to the vision test instruction.

Or when the user sees clearly, outputting a vision test instruction of 'ending the test', thereby determining the vision of the user.
The vision testing instruction may be, in addition to the voice information, gesture information, limb information, and the like of the user, and this is not particularly limited in the embodiment of the present invention.
Or after the verification of the actual distance and the ideal distance is passed, pushing an actually measured feedback result interface;
and after receiving the vision measurement feedback result, determining the vision of the user.
The actual measurement feedback interface comprises function buttons for starting testing, not clearly seeing, clearly seeing and the like, and a user touches the function buttons.
