Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which this application belongs.
At present, the eye box of the intelligent glasses based on the free-form surface binocular display scheme is small, so that the intelligent glasses cannot be compatible with the interpupillary distance range of all people (the interpupillary distance range of human eyes: 57-76 mm). In order to be compatible with pupil distance ranges of different groups, ensure an eyebox of an intelligent glasses display system and improve the accuracy of depth information, a pupil distance detection and adjustment control method needs to be provided for a free-form surface display scheme.
The question as to how large the eyebox is to fit is obviously at least as large as the human pupil. Especially in smart glasses (e.g., AR, VR glasses), the human eye needs to view the image by moving on the optical module, so the eyebox size is extended by at least several millimeters in each direction.
In addition, to support a more accurate interpupillary distance adjustment function, the eyebox also needs to be larger. Generally, the method for adjusting the interpupillary distance can be classified into a mechanical physical method or an optical adjustment method, the former method is implemented by moving an optical element, but the moved element is bulky and easy to damage and is not suitable for a wearable device such as smart glasses, and the latter method needs to increase the width of the eyebox by 10mm to 20 mm. In addition, increasing the eyebox size also faces some other challenges, such as: the larger the eyebox, the larger the size of the optical module, and even more light output is required to maintain the perceived brightness.
The related technical terms of the embodiment of the application are as follows:
pupil distance: the distance between the pupils of both eyes.
A micro-actuator: a micro-actuator that converts some form of energy into mechanical energy.
Displacement sensor of grating ruler: when two gratings with equal grating pitch are installed in parallel and the nicks of the two gratings have a small included angle, a plurality of light and dark stripes are formed on the gratings, the stripes are called moire stripes and are arranged along the direction almost perpendicular to the grating stripes. The moire fringe has the following three characteristics: 1. the displacement of the moire fringes is proportional to the displacement of the grating; 2. the moire fringes have the displacement amplification effect; 3. moire fringes have the effect of averaging out the grating errors. The photoelectric element can convert the light intensity change when the moire fringe moves into an electric signal, the signal can display the displacement in a digital form, the displacement is equal to the product of the pulse and the grid distance, and the measurement resolution is equal to the grid distance.
Magnetic grid displacement sensor: and a displacement sensor for measuring by using the magnetic action of the magnetic grid and the magnetic head.

The binocular display module 100 is disposed on the binocular module bracket 200, and forms a display system of the smart glasses with the image source module 500, and the display system may also be referred to as an optical system. The image source module 500 includes a left screen 510 and a right screen 520, the left screen 510 is used for displaying a left-eye image source picture, the right screen 520 is used for displaying a right-eye image source picture, and the image source pictures of the left screen 510 and the right screen 520 enter the eyes of the user through the optical modules in the binocular display module 100.
In the embodiment of the present application, the binocular display module 100 is a free-form surface binocular display module, which includes a left/right eye display module, and the free-form surface optical module has a better optical display effect.
Interpupillary distance detection module 300 is used for detecting the interpupillary distance of the user who wears intelligent glasses to send user's interpupillary distance to display control module, display control module is used for controlling interpupillary distance adjustment module 400.
Specifically, in the above-mentioned intelligent glasses that this application embodiment provided, interpupillary distance detection module 300 can adopt infrared ray eye movement to track the subassembly, and after the user wore intelligent glasses, infrared ray eye movement tracked the pupil that the subassembly can the automatic tracking user eyeball, and then automatic measurement obtains user's both eyes interpupillary distance.
Specifically, this infrared ray eye moves and tracks subassembly includes left eye and tracks subassembly and right eye and track the subassembly, and left eye tracks subassembly and right eye and tracks the subassembly and all comprise an infrared camera and an infrared LED light filling lamp. As shown in fig. 1, the detection scan range of the left/right eye tracking assembly is S.
The pupil distance adjusting module 400 is configured to adjust a distance between the left screen 510 and the right screen 520 in the image source module 500, so as to adjust a system pupil distance of the display system, and when the system pupil distance matches with the user pupil distance, the stereoscopic image and the real scene that the user sees can be displayed in a normally superimposed manner.
The display control module is arranged in obtaining the system interpupillary distance of display system among the above-mentioned intelligent glasses to calculate the interpupillary distance difference between user's interpupillary distance and the system interpupillary distance, and according to distance between left screen 510 and the right screen 520 in the image source module 500 is adjusted to interpupillary distance difference control interpupillary distance adjusting module 400, until the interpupillary distance difference between user's interpupillary distance and the system interpupillary distance is in predetermineeing the within range, this predetermined scope can be set for according to actual conditions, for example can set for 0, also need user's interpupillary distance and system interpupillary distance the same, also can set for a less error range, this application does not limit.
Specifically, in the above smart glasses provided in this embodiment of the present application, as shown in fig. 1, the interpupillary distance adjusting module 400 may include: micro-displacement mechanism 410, displacement sensor 420, and guide rail 430.
The micro-displacement mechanism 410 and the displacement sensor 420 are disposed on the guide rail 430, and the left screen 510 and the right screen 520 of the image source module 500 are disposed at two ends of the micro-displacement mechanism 410, respectively.
The micro-displacement mechanism 410 is configured to convert a pupil distance difference between a user pupil distance and a system pupil distance into a target displacement distance between the left screen 510 and the right screen 520 in the imaging source module according to the magnification of the display system in the smart glasses, and control the left screen 510 and the right screen 520 in the imaging source module to approach or leave the target displacement distance along the guide rail 430 in the horizontal direction. The target displacement distance refers to a distance that needs to be moved based on a current distance between the left screen 510 and the right screen 520, and the distance between the left screen 510 and the right screen 520 after the adjustment is the current distance plus or minus the target displacement distance.
For example, if the system pupil distance is the same as the user pupil distance, no pupil distance adjustment is needed; if the system interpupillary distance is smaller than the user interpupillary distance, controlling the left screen 510 and the right screen 520 in the image source module to move away from the target in the horizontal direction along the guide rail 430 to increase the system interpupillary distance; and the system interpupillary distance is larger than the user interpupillary distance, the left screen 510 and the right screen 520 in the image source module are controlled to be close to the target displacement distance in the horizontal direction along the guide rail 430 so as to reduce the system interpupillary distance.
It can be seen that, through adjusting the target displacement distance between left screen 510 and the right screen 520 in this application, utilize display system to enlarge target displacement distance in the intelligent glasses to enlarge the distance between the left/right display frame in the display system, with the user interpupillary distance of adaptation, therefore the intelligent glasses that this application provided can adjust the position of both sides image source screen display content according to different wearers' interpupillary distance, thereby realize the accurate control of stereo image degree of depth information.
The displacement sensor 420 is used to detect the displacement between the left screen 510 and the right screen 520 in the image source module. Specifically, when the displacement sensor 420 detects that the displacement of the left screen 510 and the right screen 520 approaching to each other or keeping away from each other in the image source module does not reach the target displacement distance, the display control module continuously controls the micro-displacement mechanism 410 to perform the interpupillary distance adjustment until the displacement sensor 420 detects that the displacement of the left screen 510 and the right screen 520 approaching to each other or keeping away from each other in the image source module reaches the target displacement distance, and thus the intelligent glasses provided by the application can read the displacement data of the image source screens on the two sides through the displacement sensor to perform the high-precision interpupillary distance adjustment.
According to the human eye imaging principle, the interpupillary distance is a base line for capturing the depth information of the stereoscopic image through the binocular vision of a person, and because closed-loop control is realized through interpupillary distance adjustment in the method, the adjustment precision is high, accurate stereoscopic image depth information can be obtained through calculation according to the accurate interpupillary distance, and therefore high-precision interaction can be realized.
In the above-mentioned intelligent glasses that this application embodiment provided, displacement sensor 420 can adopt grating ruler displacement sensor or magnetic grid displacement sensor, and resolution ratio more than or equal to 0.005mm, great resolution ratio has ensured the precision that displacement sensor detected to the high accuracy of interpupillary distance regulation has been ensured.
In the above smart glasses provided in the embodiments of the present application, the micro-displacement mechanism 410 includes a micro-actuator 411 and a transmission mechanism 412; specifically, the transmission mechanism 412 may adopt a flexible hinge, and the driving stroke of the micro-actuator 411 is greater than or equal to 0.2mm, and may be of the type: piezoelectric, electromagnetic or excitation types.
The micro actuator 411 is used to drive the transmission mechanism 412 so as to drive the left screen 510 and the right screen 520 in the image source module to approach or move away from each other along the guide rail 430 in the horizontal direction through the transmission mechanism 412.
Due to the amplification effect of the display system in the intelligent glasses, the micro-actuator 411 is only needed to drive the left screen 510 and the right screen 520 in the image source module to mutually approach or leave a small distance along the guide rail 430 in the horizontal direction through the transmission mechanism 412, so that the larger pupil distance can be adjusted, and the occupied space of the pupil distance adjusting mechanism is small.
In the above-mentioned intelligent glasses of this application, only need adjust like source screen position when adjusting the interpupillary distance, rather than whole display system, use micro actuator and the flexible hinge that weight is lighter to combine to control like source screen horizontal direction to remove to need not too big drive stroke, consequently occupation space is little, thereby make intelligent glasses reach light in weight, small technological effect. According to other embodiments of the present application, the micro-displacement mechanism 410 and the displacement sensor 420 may be integrated on the glass substrate of the image source screen to further reduce the occupied space.
Among the above-mentioned intelligent glasses of this application, utilize infrared ray eye to move tracking subassembly detection interpupillary distance information, utilize displacement sensor to carry out image source screen displacement closed loop and detect, can realize that user's interpupillary distance reaches unanimity with the benchmark of two mesh display screens to realize that high accuracy augmented reality shows and is mutual.
