Description

Technical Field

[0001] The present invention relates to the field of virtual reality technology, and in particular to an object distance control method for a virtual reality device and a controller thereof, and a virtual reality device. Background Art

[0002] Virtual Reality (VR) technology is a computer-generated, interactive, immersive visual virtual environment proposed in the 1980s. It can generate a variety of virtual environments as needed.

[0003] In recent years, with the development of computer computing power and various types of sensors, various types of virtual reality helmets have appeared on the market. They are basically composed of a display screen or a mobile phone and a pair of eyepieces. The human eye can see the magnified image on the display screen through the eyepieces. The sensor senses the changes in the human head and adjusts the images in the left and right display screens, so that the human eye can see a three-dimensional, interactive visual image. However, in order to improve the effect, most of them adopt a closed structure, which causes myopic users to wear their own glasses first and then wear VR glasses when using VR devices, which makes the user easily tired and inconvenient to wear. In order to enable myopic users to see the image on the display screen clearly without wearing their own glasses, the prior art manually adjusts the distance between the lens and the user's eyes by the user. However, in the manual adjustment process, the manual adjustment amplitude is not easy to control, so that the adjustment accuracy is not high, and the user may not be able to adjust to a clearer result after many adjustments, thereby reducing the user's experience.

When the first connecting portion 15 moves up and down relative to the second shell 212, the sealing ring 14 always seals the first connecting portion 15 and the second shell 212, so that the entire lens device is always in a sealed state, thereby preventing dust from accumulating on the lens 13, thereby further improving the clarity of the VR video viewed by the user and further enhancing the user's experience.

For example, Figure 3 is a cross-sectional view of the lens device before adjustment. After the lens holder 11 is adjusted to move upward H relative to the lens barrel 21, the cross-sectional view of the lens device after adjustment is as follows: Figure 4 shown.

[0042] As a second aspect of the present application, the present application provides an object distance control method based on a virtual reality device. Figure 5 FIG. 1 is a flow chart of a method for controlling object distance based on a virtual reality device provided by an embodiment of the present application. Figure 5 As shown, the object distance control method based on virtual reality equipment includes the following steps:

[0043] Step S10: Obtaining the degree information of the user's refractive error;

[0044] Specifically, the refractive error degree information includes myopia degree information and hyperopia degree information. The user's myopia degree information includes the user's left eye myopia degree and the right eye myopia degree. The user's left eye myopia degree and the right eye myopia degree may be the same or different. Similarly, the hyperopia degree information also includes the user's left eye hyperopia degree information and the right eye hyperopia degree information. The user's left eye hyperopia degree and the right eye hyperopia degree may be the same or different.

[0045] There are several ways to obtain the user's refractive error degree information (such as hyperopia degree information or myopia degree information):

[0046] (1) When the user uses the virtual reality device for the first time, the user's refractive error degree information (such as myopia degree information) is the myopia degree information directly input by the user. For example, the user inputs the myopia degree of the left eye and the myopia degree of the right eye respectively, and the myopia degree information of the user can be obtained.

[0047] (2) When it is not the first time for the user to use the virtual reality device, and it is the first time for the user to use the virtual reality device, the user information of the user has been stored, and the user information includes the user's identity information, facial information, and refractive error degree information (such as hyperopia degree information or myopia degree information). Therefore, when the user uses the virtual reality device again, the facial recognition unit in the virtual reality device can recognize the user's facial information, thereby identifying the user's identity information, and determine the user's refractive error degree information based on the user's identity information, such as the user's left eye myopia degree and the right eye myopia degree.

[0048] Step S20: calculating the actual displacement value of the lens movement according to the corresponding relationship between the relative position between the lens holder and the lens barrel and the degree information of the refractive error, the degree information of the refractive error of the user, and the current relative position between the lens holder and the lens barrel;

[0049] Specifically, when calculating the actual displacement value of the lens movement, the actual displacement value and the calculation process of the actual displacement value are closely related to the specific structural design of the lens device.

[0050] For example, for Figure 1-Figure 4 For the lens device shown in the figure, step S20 is to calculate the displacement value of the lens holder 11 moving up and down relative to the lens barrel 21 , that is, to calculate the distance H that the lens holder 11 moves upward relative to the lens barrel 21 .

[0051] Specifically, the distance that the lens holder 11 can move up and down relative to the lens barrel 21 is provided with a moving thread, that is, the relative position between the lens holder 11 and the lens barrel 21 includes an upper limit position and a lower limit position, that is, the lens holder 11 moves upward relative to the lens barrel 21 as far as the upper limit position, and the lens holder 11 moves downward relative to the lens barrel 21 as far as the lower limit position.

[0052] For the convenience of calculation: the corresponding relationship between the relative position between the lens holder 11 and the lens barrel 21 and the degree information of the refractive error can be set, specifically: (1) when the virtual reality device is used by a myopic user, the lower limit position can be determined as the relative position between the lens holder 11 and the lens barrel 21 when the user's myopia is 0; the upper limit position can be determined as the relative position between the lens holder 11 and the lens barrel 21 when the user's myopia is 800 degrees; when the lens holder 11 moves up and down by a distance h1 relative to the lens barrel 21, the myopia increases or decreases by a1 degree; (2) when the virtual reality device can be used by both myopic and hyperopic users, the middle position of the moving thread can be determined as the time when the user's myopia is 0. The myopic user can adjust the lens holder 11 to move upward relative to the lens barrel 21, with the middle position as the starting position. When it moves upward by h2, the corresponding myopia increases by a2 degrees; the hyperopic user can adjust the lens holder 11 to move downward, with the middle position as the starting position. When it moves downward by h3, the corresponding hyperopia increases by a3 degrees. (3) When the virtual reality device is used by a hyperopic user, the upper limit position can be determined as the relative position between the lens holder 11 and the lens barrel 21 when the hyperopia degree is 0; the lower limit position can be determined as the relative position between the lens holder 11 and the lens barrel 21 when the user's hyperopia degree is 500 degrees.

[0053] Specifically, when calculating the actual displacement value of the lens movement in step S20, the calculation can be based on the correspondence between the relative position between the lens holder 11 and the lens barrel 21 and the degree information of the refractive error, the relative position between the front lens holder 11 and the lens barrel 21 can be adjusted, and the degree information of the refractive error of the user can be used together for calculation. For example, the correspondence between the relative position between the lens holder 11 and the lens barrel 21 and the degree information of refractive error is: the lower limit position is determined to be the relative position between the lens holder 11 and the lens barrel 21 when the user's myopia degree is 0; the upper limit position is the relative position between the lens holder 11 and the lens barrel 21 when the user's myopia degree is 800 degrees; when the lens holder 11 moves up and down a distance h1 relative to the lens barrel 21, the myopia degree increases or decreases by a1 degree; before adjustment, the position of the lens holder 11 relative to the lens barrel 21 is: the lens holder 11 is located at the lower limit position, at this time, the actual displacement value of the lens movement, that is, the actual displacement value of the lens holder 11 relative to the lens barrel 21, can be calculated according to the correspondence between the myopia degree information, the relative position between the lens holder 11 and the lens barrel 21, and the degree information of refractive error.

[0054] Step S30: According to the actual displacement value of the lens movement, the lens adjusting device is controlled to adjust the lens bracket 11 to move up and down relative to the lens barrel 21 to adjust the distance between the lens and the user's eyes.

[0055] After the actual displacement value of the lens holder 11 relative to the lens barrel 21 is calculated in step S20, the lens holder 11 can be regulated to move up and down relative to the lens barrel 21 according to the actual displacement value. Specifically, whether to move up or down, and how to control the moving parts in the lens device to move in order to achieve the actual displacement value of the lens holder 11 relative to the lens barrel 21 can be determined according to the specific structure of the lens device. For example, the lens device adopts Figure 1-Figure 4 When the lens device shown in the figure is used, the rotation direction and number of rotations of the transmission motor 31 can be calculated according to the actual displacement value required to be moved.

[0056] The corresponding relationship between the relative position between the lens holder 11 and the lens barrel 21 and the degree information of the refractive error is as follows: the lower limit position is determined to be the relative position between the lens holder 11 and the lens barrel 21 when the user's myopia degree is 0; the upper limit position is the relative position between the lens holder 11 and the lens barrel 21 when the user's myopia degree is 800 degrees; when the lens holder 11 moves up and down a distance h1 relative to the lens barrel 21, the myopia degree increases or decreases by a1 degree; before adjustment, the position of the lens holder 11 relative to the lens barrel 21 is as follows: the lens holder 11 is located at the lower limit position, when the actual displacement value H of the lens holder 11 relative to the lens barrel 21 is calculated according to the corresponding relationship between the user's myopia degree information, the relative position between the lens holder 11 and the lens barrel 21 and the degree information of the refractive error, it can be determined according to the actual displacement value H that the transmission motor 31 needs to rotate n1 circles clockwise to drive the lens holder 11 to move upward by the actual displacement value H relative to the lens barrel 21, and the lens device before and after adjustment is as follows Figure 3 as well as Figure 4 shown.

[0057] The object distance adjustment method provided by the present application automatically calculates the actual displacement value of the lens holder that needs to be moved relative to the lens barrel according to the refractive error degree information input by the user when the user with refractive error uses the virtual reality device, and then adjusts the movement of the lens holder relative to the lens barrel according to the actual displacement value, thereby adjusting the distance between the lens barrel and the user's eyes, so that the user with refractive error can see a clear display image on the display screen without wearing corrective glasses (such as myopia glasses or hyperopia glasses), thereby improving the user experience. Since the adjustment is automatic, the actual displacement value of the adjustment is also accurately calculated according to the refractive error degree information, thereby increasing the accuracy of the adjustment compared to manual adjustment by the user.

[0058] In one embodiment of the present application, Figure 6 As shown, step S30 (controlling the lens control device to control the lens holder to move up and down relative to the lens barrel according to the actual displacement value of the lens movement) specifically includes the following steps:

[0059] Step S301: controlling the lens adjusting device to adjust the lens holder to move to a first position relative to the lens barrel for the first time according to the displacement value of the lens movement;

[0060] Step S302: when the lens holder is moved relative to the lens barrel, first feedback information is generated, and the first feedback information is used to indicate that the control is completed;

[0061] Step S303: whether information indicating that the displayed image is clear is received;

[0062] When the user sees the first feedback information, the lens device after the first adjustment can be used, and the user can give feedback on whether the display image is clear (i.e., whether the display image is clear). For example, when the user can see the display image on the display screen clearly, the user can click a button indicating that the display image is clear (e.g., a confirmation key), i.e., the user inputs the image clarity information. When the user receives the image clarity information input by the user, the adjustment is ended. When the user sees the first feedback information, the lens device after the first adjustment is used. When the user sees that the display image on the display screen is blurry, the user can click a button indicating that the display image is clear (e.g., click a continue adjustment button or an unclear button or a negative key), and it can be determined that the user needs to adjust again. At this time, the adjustment needs to be continued, i.e., step S304 is executed.

[0063] Step S304: Based on the preset displacement value, the lens adjusting device is controlled to adjust the lens holder to move to the second position relative to the lens barrel with the first position as the starting point;

[0064] Specifically, the preset displacement value may be pre-set, for example, the preset displacement value corresponds to a preset adjustment degree, that is, fine-tuning the position of the lens holder relative to the lens barrel to fine-tune the distance between the lens and the user's eyes.

[0065] Specifically, the preset adjustment degree may be 30-50 degrees.

[0066] Step S305: after the lens holder has completed its movement relative to the lens barrel, second feedback information is generated, and the second feedback information is used to indicate that the control is completed.

[0067] When the user sees the second feedback information, the user can provide feedback on whether the displayed image is clear (i.e., whether the user receives the information on whether the displayed image is clear). For example, when the user can see the displayed image on the display screen clearly, the user can click a button indicating that the displayed image is clear (e.g., a confirmation button), i.e., the user inputs the information on the clear image. When the user receives the information on the clear image input by the user, the control is terminated. When the user sees the second feedback information, the lens device after the second control is used. When the user sees that the displayed image on the display screen is blurry, the user can click a button indicating that the displayed image is clear (e.g., a continue control button or an unclear button or a negative button), i.e., the user inputs the information on continuing the control or the information on the unclear image. It can be determined that the user needs to control again. At this time, the control needs to be continued, i.e., steps S303 to S305 are executed.

[0068] When the user sees the second feedback information, the user uses the lens device after the second adjustment. When the user sees that the display screen is blurry, the user can click the continue adjustment button or the unclear button. That is, the user inputs the continue adjustment information or the unclear picture information, and it can be determined that the user needs to adjust again. At this time, it is necessary to continue the adjustment, that is, execute steps S303-S305, until the display screen seen by the user is clear, and end the adjustment, that is, step S306.

[0069] That is, when fine-tuning the position of the lens holder relative to the lens barrel, the fine-tuning may be performed multiple times until the display image seen by the user is clear, that is, steps S303 to S305 may be performed once or repeatedly. Each time the fine-tuning is performed, the position of the lens holder relative to the lens barrel after the last fine-tuning is used as the starting point for fine-tuning the preset displacement value.

[0070] In one embodiment of the present application, when step S306 ends the regulation, the user will use the regulated virtual reality device to experience virtual reality. When the experience is completed, the user can input information indicating that the task is completed (for example, click a completion button). When the task completion information input by the user is received, step S307 is executed.

[0071] Step S307: when receiving the task completion information input by the user, recording the position of the lens holder relative to the lens barrel;

[0072] The position of the lens holder relative to the lens barrel is the position of the lens holder relative to the lens barrel when the user can see a clear display image after adjustment from step S301 to step S306.

[0073] Step S308: Bind the position of the lens holder relative to the lens barrel with the user information of the user and store them as the user information of the user.

[0074] The position of the lens holder relative to the lens barrel is bound to the user's personal information and stored as the user's user information, and the personal information may include the user's facial information and other identity information. When the user uses the virtual reality device again next time, after identifying the user, the position of the lens holder corresponding to the user relative to the lens barrel can be determined, and the lens holder can be automatically adjusted to the position without having to perform steps S301 to S306 again, thereby reducing the complexity of use and improving the user experience.

[0075] In one embodiment of the present application, Figure 7 As shown, after step S10 and before step S20, the object distance control method further includes the following steps:

[0076] Step S101: Determine whether the lens holder is in an initial position. The initial position is the position of the lens relative to the lens barrel when the user has normal refraction. For example, when the virtual reality device is used by a myopic user, the lower limit position can be determined as the relative position (i.e., the initial position) between the lens holder 11 and the lens barrel 21 when the user's myopia is 0.

[0077] When it is determined that the lens holder is located at the initial position, step S20 (calculating the actual displacement value of the lens movement according to the correspondence between the relative position between the lens holder and the lens barrel and the degree information of the refractive error, the degree information of the refractive error of the user, and the current relative position between the lens holder and the lens barrel) may specifically include the following steps:

[0078] Step S201: calculating the actual displacement value of the lens movement according to the corresponding relationship between the relative position between the lens holder and the lens barrel and the degree information of the refractive error and the degree information of the refractive error of the user.

[0079] When it is determined that the lens holder is not located at the initial position, step S20 (calculating the actual displacement value of the lens movement according to the correspondence between the relative position between the lens holder and the lens barrel and the degree information of the refractive error, the degree information of the refractive error of the user, and the current relative position between the lens holder and the lens barrel) may specifically include the following steps:

[0080] Step S202: calculating the actual displacement value of the lens movement according to the correspondence between the relative position between the lens holder and the lens barrel and the degree of refractive error information, the current relative position, the initial position and the degree of refractive error information of the user; or

[0081] Step S203: controlling the lens holder to move to an initial position;

[0082] When the lens holder moves to the initial position, step S201 is executed, that is, the actual displacement value of the lens movement is calculated according to the corresponding relationship between the relative position between the lens holder and the lens barrel and the degree information of the refractive error and the degree information of the refractive error of the user.

[0083] In another embodiment of the present application, Figure 8 As shown, after step S30 (controlling the lens control device to control the lens holder to move up and down relative to the lens barrel according to the actual displacement value of the lens movement), the object distance control further includes the following steps:

[0084] Step S40: When the user finishes using the virtual reality device, the lens holder is controlled to be adjusted to the initial position. The initial position is the position of the lens relative to the lens barrel when the user has normal refraction. For example, when the virtual reality device is used by a myopic user, the lower limit position can be determined as the relative position (i.e., the initial position) between the lens holder 11 and the lens barrel 21 when the user's myopia is 0.

[0085] When another user uses the virtual reality device again, the lens holder is in the initial position. Therefore, there is no need to determine whether the lens holder is in the initial position, and step S201 can be directly executed: the actual displacement value of the lens movement is calculated according to the correspondence between the relative position between the lens holder and the lens barrel and the refractive error degree information and the refractive error degree information of the user.

[0086] In another embodiment of the present application, Fig. 9 As shown, before step S10 (obtaining the degree information of the user's refractive error), the object distance adjustment method further includes the following steps:

[0087] Step S1: Obtaining user's facial recognition information;

[0088] Step S2: determining whether the user is using the virtual reality device for the first time based on the user's facial recognition information;

[0089] Specifically, every time a user uses the virtual reality device for the first time, the user's facial recognition information will be saved as the user's personal information, and the user's personal information will be stored in the memory. The method for determining whether the user is using the virtual reality device for the first time may be: searching the user's facial recognition information in the memory, and when personal information matching the user's facial recognition information is found, it can be determined that the user is not using the virtual reality device for the first time. When no personal information matching the user's facial recognition information is found, it can be determined that the user is using the virtual reality device for the first time.

[0090] When the judgment result in step S2 is yes, that is, the user is using the virtual reality device for the first time, then step S3 is executed, that is, the facial recognition information of the user is stored as the personal information of the user. In this case, step S10 (obtaining the degree information of the refractive error of the user) specifically includes step S102: obtaining the degree information of the refractive error input by the user, that is, when the user is using the virtual reality device for the first time, the degree information of the refractive error of the user is input by the user himself.

[0091] When the judgment result in step S2 is no, that is, it is not the first time for the user to use the virtual reality device, step S4 is executed at this time, that is, the user's personal information is determined based on the user's facial recognition information. In this case, step S10 (obtaining the user's refractive error degree information) specifically includes step S103: searching for the user's refractive error information based on the user's personal information. Because when the user uses the virtual reality device for the first time, the user's personal information (such as facial recognition information) and the refractive error degree information are bound and stored as the user's user information, that is, when the user's personal information is determined, the user's refractive error degree information can be determined. The user does not need to enter his or her own refractive error degree information, and the virtual reality device can automatically adjust the position of the lens holder relative to the lens barrel.

[0092] Specifically, the user's facial recognition information may include but is not limited to: the user's lip information and / or the user's pupil distance information and / or the user's face information. Step S1 (obtaining the user's facial recognition information) specifically includes the following steps:

[0093] Step S11: Obtaining the user's lip information; and / or

[0094] Specifically, the user's lip information can be acquired by photographing through a first camera device disposed in the lens device.

[0095] Step S12: Obtaining the user's pupil distance information; and / or

[0096] Specifically, the pupil distance information of the user can be obtained by taking a pupil photo of the user through a second camera device disposed in the lens device, and then analyzing and calculating the pupil distance information of the user based on the pupil photo of the user.

[0097] Step S13: Obtaining the user's facial information;

[0098] Specifically, the user's facial information can be acquired by photographing a third camera device disposed in the lens device.

[0099] As a third aspect of the present application, the present application also provides an object distance control controller based on a virtual reality device, Fig.10FIG. 1 is a schematic diagram of a structure of an object distance control controller based on a virtual reality device provided in an embodiment of the present application. Fig.10 As shown, the object distance control controller 1 includes:

[0100] The data acquisition unit 11 acquires the myopia degree information of the user; that is, the data acquisition unit 11 is used to execute step S10 in the above-mentioned object distance control method based on virtual reality equipment.

[0101] The calculation unit 12 is used to calculate the actual displacement value of the lens movement according to the correspondence between the relative position between the lens holder and the lens barrel and the degree information of the refractive error, the degree information of the refractive error of the user, and the current relative position between the lens holder and the lens barrel; that is, the calculation unit 12 is used to execute step S20 in the above-mentioned object distance control method based on the virtual reality device.

[0102] The control unit 13 is used to control the lens control device to control the lens holder to move up and down relative to the lens barrel according to the actual displacement value of the lens movement, so as to adjust the distance between the lens and the user's eyes. That is, the control unit 13 is used to perform step S30 in the object distance control method based on the virtual reality device.

[0103] In one embodiment of the present application, Fig.11 As shown, the control unit 13 includes:

[0104] The control module 131 is used to control the lens control device to control the lens holder to move to the first position relative to the lens barrel for the first time according to the displacement value of the lens movement, and when receiving the continuous control information input by the user, based on the preset displacement value, the lens control device is controlled to control the lens holder to move to the second position relative to the lens barrel based on the first position as the starting point; that is, the control module 131 executes step S301 and step S304 in step S30 of the object distance control method based on the virtual reality device described above. That is, the relative position between the lens holder and the lens barrel is adjusted once or multiple times until the user can see a clear display image.

[0105] The feedback module 132 is used to receive the continued control information input by the user, and generate feedback information when the lens holder is moved relative to the lens barrel. That is, when the control module 131 completes the control of the lens holder relative to the lens barrel, the control completion information is given to the user, and the user verifies the display screen on the display screen according to the feedback information. If the display screen is clear, the confirmation key can be pressed. If the display screen is not clear, the negative key can be pressed, and the control module 131 will control the position of the lens holder relative to the lens barrel again. That is, the feedback module 132 is used to execute step S302 and step S305 in step S30 of the object distance control method based on the virtual reality device described above.

[0106] In another embodiment of the present application, Fig.12 As shown, the control unit 13 also includes: a storage module 133, which is used to bind the position of the lens holder relative to the lens barrel with the user's personal information and store it as the user information of the user after the feedback module 132 generates the task completion information. Among them, the object distance control controller also includes: a facial recognition unit 14, which is communicatively connected with the storage module 133, and the facial recognition unit 14 is used to recognize the user's facial recognition information and send the user's facial recognition information to the storage module 133.

[0107] That is, when the user completes the experience of the virtual reality device, the storage module 133 binds the user's personal information (including the user's facial information, the user's refractive error degree information) and the position of the lens holder relative to the lens barrel and stores them as the user's user information (that is, the user's user information includes the user's personal information and the position of the lens holder relative to the lens barrel). When the user uses the virtual reality device again next time, the user's face can be recognized to determine the user's facial information, and then the personal information is determined based on the facial information, and the position of the lens holder relative to the lens barrel is determined. After the position of the lens holder relative to the lens barrel is determined, the lens holder can be regulated according to the real-time position of the lens holder relative to the lens barrel when the user wears the virtual reality device and the position of the lens holder relative to the lens barrel, so that the lens holder moves to the position.

[0108] Specifically, Fig.12 As shown, the facial recognition unit 14 specifically includes but is not limited to: a first camera device 141, used to take a picture of the user's lips; and / or a second camera device 142, used to take a picture of the user's eye pupil; and / or a third camera device 143, used to take a picture of the user's face.
