Description

Technical Field

[0001] The present invention relates to the technical field of vision detection, and particularly to an intelligent glasses interaction method and system. Background Art

[0002] The eyes are an important organ of human beings. Through the eyes, people can see the beautiful things in the outside world. However, with the increasing pressure of people's study, work and life, eyesight has been severely damaged. In this case, the examination of eyesight is extremely important. If problems are detected, early intervention can be carried out to protect the eyes. There are usually two methods for eyesight examination: (1) The eye chart, which is divided into a far vision chart and a near vision chart. Usually, the far vision chart given by hospitals is the E-shaped eye chart at a distance of five meters. When the eyesight measured by the eye chart is poor, less than 1.0, the near vision chart can also be measured. The distance of the near vision chart is usually 30 cm. If 1.0 can be read, it means that the far vision is problematic and the near vision is good, that is, myopia. If the far vision chart is good and the near vision chart is poor, it means hyperopia or presbyopia; (2) Refraction measurement. A computer refractometer can measure the degree of a normal adult. By trying on relevant lenses according to the degree to improve eyesight, the refractive state of the patient can be measured more accurately. However, the existing eyesight examinations all require the cooperation of eyesight examination personnel, which is time-consuming and laborious, and the examination efficiency is not high, wasting resources and reducing the accuracy of the examination results to a certain extent.

[0003] Prior art one, CN201310608989.X, an eyesight examination instrument and an eyesight examination method, including an eye chart display device, a lens with a function of extending the observation distance of the human eye, and a box with a definite shape; the eye chart display device and the lens with a function of extending the observation distance of the human eye are installed in the box with a definite shape; the box with a definite shape is provided with an observation hole in front of the lens with a function of extending the observation distance of the human eye. Although the distance at which the human eye sees the eye chart is extended by using the lens with a function of extending the observation distance of the human eye as the standard distance for eyesight examination, which can solve the problems of eyesight examination restricted by manpower and environmental conditions and realize real-time hands-held eyesight examination, it lacks the initiative to examine eyesight, making the examined object passively undergo the examination. Moreover, due to some objective factors of the eyesight examination personnel (such as language, speaking strength and speech rate, etc.), the examined object cannot accurately obtain the information of the eye chart, reducing the efficiency of eyesight examination.

[0004] Prior Art Two, CN201610866738.5, a device for vision examination, includes a bracket, a gear assembly and an occlusion assembly. The occlusion assembly includes a first occlusion board and a second occlusion board. The first occlusion board and the second occlusion board are located on both sides of the bracket. The first occlusion board and the second occlusion board are respectively installed on two rotating rods of the bracket. The gear assembly includes a first gear, a second gear and a third gear. The first gear, the second gear and the third gear are all bevel gears. The rotating rod can rotate together with the first occlusion board and the second occlusion board. The end of the rotating rod connected to the first occlusion board is installed with the first gear, and the end of the rotating rod connected to the second occlusion board is installed with the second gear. The first gear and the second gear are simultaneously meshed with the third gear. Although it is convenient to wear to occlude one eye to achieve vision detection and ensure the accuracy of the examination, there is a lack of interactivity between the examinee and the vision detector, resulting in poor interaction ability, which affects the efficiency of vision examination to a certain extent.

[0005] Prior Art Three, CN201780017914.0, a vision examination method, a vision examination instrument and a download server storing a program of the vision examination method. The vision examination method includes the following steps: displaying a visual target image and a plurality of reference images; receiving a response corresponding to the visual target image; and judging whether the reference image determined by the response is the same shape as the visual target image among the plurality of reference images. In addition, one of the plurality of reference images has the same shape as the visual target image. Although accurate vision examination can be performed, this vision examination instrument lacks cooperation with glasses during vision examination, resulting in poor interaction ability.

[0006] Currently, in Prior Art One, Prior Art Two and Prior Art Three, the examinee is made to undergo the examination passively. Due to objective factors, the examinee cannot accurately obtain the information of the vision chart, which reduces the efficiency of vision examination. Moreover, there is a lack of interactivity between the examinee and the vision detector, resulting in poor interaction ability, which affects the efficiency of vision examination to a certain extent. Therefore, the present invention provides an intelligent glasses interaction method and system, which realizes voice interaction between the glasses and the vision examination instrument through the voice interaction function, enables the vision chart information to be accurately transmitted to the examinee, and enhances the interactivity between devices.

[0008] The examinee wears glasses, turns on the power of the glasses, and under the control of the voice interaction device, the projector projects a certain character in the vision examination form onto the screen.

[0009] The examinee speaks the voice of the orientation of the character on the screen, and the receiver receives the voice and transmits it to the voice interaction device for recognition.

[0010] The voice interaction device emits a voice signal to continue recognizing characters. The voice signal is played by the player.

If the light intensity reaches the preset light threshold, continue to project; if the light intensity does not reach the preset light threshold, perform light compensation;

[0014] The projector filters the character image to be projected and retains the edge information of the characters on the visual acuity chart.

[0015] Optionally, the process of the voice interaction device for recognition includes:

[0018] When the error rate exceeds the first preset threshold, automatically move up one line of the characters on the visual acuity chart;

[0019] When the accuracy rate of the feedback voice reaches the second preset threshold, record the visual acuity result of the examined object.

[0020] Optionally, when the error rate exceeds the first preset threshold, the visual acuity chart starts to let the examined object read the characters in the previous line. If the error rate still exceeds the first preset threshold, continue to move up until reaching the top line of the visual acuity chart; when the correct rate reaches the second preset threshold, the line where the current character is located is the visual acuity value of the examined person, and the visual acuity value is displayed.

[0021] Optionally, the process of the voice interaction device comparing the feedback voice with the opening direction of the pre-stored characters includes:

[0022] The voice interaction device pre-stores the voice of the opening direction of each character on the visual acuity chart; each voice corresponds to the character on the visual acuity chart one by one;

[0023] When the feedback voice reaches the voice interaction device, compare the pre-stored current character voice with the feedback voice. When the waveforms and spectra of the pre-stored current character voice and the feedback voice are the same, it proves that the feedback voice is correct, otherwise the feedback voice is incorrect.

[0026] The player receives a voice signal for continuing to recognize characters;

[0027] The player plays the voice signal for continuing to recognize characters sent by the voice interaction device according to the adjusted volume.

[0028] Optionally, the process of the player adjusting the volume of the player according to the sound decibels includes:

[0029] Collect the changes in the surrounding environmental sounds through a sound sensor;

[0030] Generate the change in the environmental sound signal at the current time according to the change and generate a sensing signal;

[0038] First, the subject wears glasses and turns on the power of the glasses. Under the control of the voice interaction device, the projector projects a certain character in the visual acuity chart onto the curtain. Then, the subject speaks the voice of the orientation of the character on the curtain, and the receiver receives the voice and transmits it to the voice interaction device for recognition.

[0051] Embodiment 1

[0052] As Figure 1 shown, the embodiment of the present invention provides an intelligent glasses interaction method, including the following steps:

[0053] S100: The object to be examined wears the glasses, turns on the power of the glasses, and under the control of the voice interaction device, the projector projects a certain character in the visual acuity test chart onto the screen;

[0054] S200: The object to be examined speaks the voice of the orientation of the character on the screen, the receiver receives the voice, and conveys it to the voice interaction device for recognition;

[0055] S300: The voice interaction device sends out a voice signal to continue recognizing the character, the voice signal is played by the player, and the voice interaction device continues to control the projector according to a preset program, and outputs the recognition result of the visual acuity test chart to the terminal;

[0056] The working principle and beneficial effects of the above technical solution are as follows: In this embodiment, first, the object to be examined wears glasses and turns on the power of the glasses. Under the control of the voice interaction device, the projector projects a certain character in the visual acuity test chart onto the screen. Then, the object to be examined speaks the voice of the orientation of the character on the screen, and the receiver receives the voice and transmits it to the voice interaction device for recognition. Finally, the voice interaction device sends out a voice signal to continue recognizing the character. The voice signal is played by the player, and the voice interaction device continues to control the projection according to the preset program. Finally, the recognition result of the visual acuity test chart is output to the terminal. The distance between the object to be examined and the screen in the above solution is preset in advance and does not need to be adjusted. By setting the voice interaction device, the interaction function of the glasses is realized, the character is automatically projected, and the result is automatically recognized, realizing the automatic display and automatic recognition of the visual acuity test chart, saving the complexity of manual participation, and improving the intelligence of the system. By setting the projector and the voice interaction device, the interactivity of the visual acuity tester is realized. The glasses in this embodiment utilize the frame of the glasses and do not involve the structure of the lens. The projector, voice interaction device, receiver, and player are installed on the frame of the glasses, and the device is used by wearing it. The devices are centrally set on the frame, and each device works automatically to realize the automation of visual acuity inspection. By setting the receiver and player on the glasses, the intelligence of the glasses (the glasses worn by the object to be examined during visual acuity inspection) is improved, and the participation of the examiner is not required. Only the object to be examined can complete it alone, simplifying the visual acuity inspection procedure, improving the visual acuity inspection efficiency, effectively improving the interactivity of the glasses, and also improving the accuracy and precision of visual acuity inspection.

[0057] Embodiment 2

[0058] As Figure 2 shown, on the basis of Embodiment 1, the process of light compensation of the projector provided by the embodiment of the present invention includes:

[0059] S101: Start the light compensation module under the control of the projector;

[0060] S102: The light compensation module feeds back the light intensity to the projector through the light sensor. The projector judges the light intensity. If the light intensity reaches the preset light threshold, continue to project; if the light intensity does not reach the preset light threshold, perform light compensation;

[0061] S103: The projector filters the character image to be projected and retains the edge information of the characters in the visual acuity test chart.

[0062] The working principle and beneficial effects of the above technical solution are as follows: In this embodiment, the light compensation module is first started under the control of the projector; secondly, the light compensation module feeds back the light intensity to the projector through the light sensor, and the projector judges the light intensity. If the light intensity reaches the preset light threshold, projection continues; if the light intensity does not reach the preset light threshold, light compensation is performed; finally, the projector filters the character image to be projected and retains the edge information of the characters on the visual acuity chart. The above solution realizes that the characters projected by the projector can be clearly displayed through the light compensation module, greatly reducing the problem that the visual acuity examination of the examined object is inaccurate due to the objective factor of light, and further improving the accuracy of the visual acuity examination results. The visual acuity tester also anticipates the light intensity to ensure that the light is within a reasonable threshold range, ensuring that the examined object can obtain the best light. After the light compensation, the characters are projected. Since the light compensation has been performed previously, the characters seen by the examined object are clearer. The projector preprocesses the characters on the visual acuity chart, mainly performing filtering. Through filtering, the noise of the character image is eliminated, and the edge information of the characters for visual acuity examination is retained, ensuring that the characters on the visual acuity chart projected by the projector are complete and will not affect the accuracy of the visual acuity examination results.

[0063] Embodiment 3

[0064] Based on Embodiment 2, the filtering model adopted by the projector provided by the embodiment of the present invention for filtering the character image is as follows:

[0065]

[0066] Among them, F(i,j) represents the gray value of the character image before filtering at the coordinate (i,j), represents the gray value of the character image after filtering at the coordinate (x,y), r represents the window radius of the filter, and Ω r,x,y represents the set of pixel coordinates within a square region with side length (2r + 1) centered at (x,y), and ω r (i,j) represents the gray similarity weight of the coordinate (i,j), and σ d and σ r respectively represent the spatial standard deviation and the gray standard deviation.

[0067] The working principle and beneficial effects of the above technical solution are as follows: The projector filters the character image to be projected and retains the edge information of the characters on the visual acuity chart. Through the above filtering model, filtering is realized, the noise in the character image is removed, the edge information of the characters is retained to the greatest extent, the integrity and accuracy of the character image are improved, the gray value of the character image is maintained, the accuracy of the visual acuity examination results is guaranteed, and the experience and comfort of the examined object are also improved.

[0072] S203: When the error rate exceeds the first preset threshold, automatically move up one line of the characters on the vision test chart;

[0073] S204: When the accuracy rate of the feedback voice reaches the second preset threshold, record the vision result of the object to be examined.

[0075] Example 5

[0076] On the basis of Example 4, the process of the voice interaction device provided by the embodiment of the present invention for comparing the feedback voice with the opening direction of the pre-stored characters includes:

[0077] The voice interaction device pre-stores the voice of the opening direction of each character on the vision test chart; each voice corresponds to a character on the vision test chart one by one;

[0078] When the feedback voice reaches the voice interaction device, the currently stored character voice is compared with the feedback voice. When the waveform spectra of the currently stored character voice and the feedback voice are consistent, it proves that the feedback voice is correct; otherwise, the feedback voice is incorrect.

[0079] The working principle and beneficial effects of the above technical solution are as follows: In this embodiment, first, the voice interaction device pre-stores the voices of the opening directions of each character in the visual acuity chart; each voice corresponds to a character in the visual acuity chart. Second, when the feedback voice reaches the visual acuity tester, the currently stored character voice is compared with the feedback voice. When the waveform spectra of the currently stored character voice and the feedback voice are consistent, it proves that the feedback voice is correct; otherwise, the feedback voice is incorrect. By comparing the waveform spectra of the voices, the verification of whether the feedback voice is correct is realized. The preset voices corresponding to the characters improve the efficiency of feedback voice recognition, eliminate the complexity of multiple judgments and comparisons, and are fast and accurate.
