[0062] Such as figure 1 As shown in the schematic flow chart of the first embodiment of the present invention, a method for adjusting the interpupillary distance of a virtual reality helmet includes the following steps:

[0063] S200: the interpupillary distance detection module detects the interpupillary distance of the helmet wearer;

[0064] S300: The calculation module calculates the size of the left and right screen display areas according to the interpupillary distance and the imaging relationship between the human eye and the lens;

[0065] S400: The display displays the left and right screen display areas and positions on the display according to the calculation result of the calculation module.

[0066] Preferably, the method for adjusting the interpupillary distance of a virtual reality helmet further includes the following steps after the step S400:

[0067] S500: When the display is a display screen, the display screen displays a left screen area and a right scre...

[0081] On the basis of Embodiment 1, this embodiment further preferably provides a virtual reality helmet, such as Figure 4 As shown in the schematic diagram of the VR helmet module in the second embodiment of the present invention, the virtual reality helmet includes an adjustment module 150,

[0082] The adjustment module is used for fine-tuning the size and / or position of the left and right screen display areas displayed on the display.

[0083] Preferably, in the virtual reality helmet, the adjustment module 150 includes a controllable resistance screw 155, an ADC digital-to-analog conversion device 156,

[0084] The controllable resistance screw 155 is used to manually adjust the size of the resistance;

[0085] The ADC digital-to-analog conversion device 156 outputs a corresponding voltage according to the adjustment result of the controllable resistance spiral 155 ; the outputted voltage is used to participate in the calculation process of the calculation module 140 ....

[0092] People's faces are different in size, and the interpupillary distance of people is not fixed. The interpupillary distance of children is small, and the interpupillary distance of adults is large, and the interpupillary distance of a person is also changing with the growth of grades. Generally, the interpupillary distance of adult men The distance is between 60-73MM and 53-68MM for women. Physically adjust the distance between the lens and the screen to adjust the interpupillary distance. The overall structure of the product is complicated, the operation is cumbersome, the adjustment is inaccurate and the deviation is large, and the volume and weight of the whole machine are increased. It is easy to fatigue and dizzy when worn for a long time, which is not good for the neck and eyes. healthy.

[0093] In order to solve the appealing problem, this embodiment proposes a new technical solution for adjusting the VR interpupillary distance. Such as Figure 5 It is shown in ...

Abstract

The invention discloses a virtual reality helmet and a method for adjusting the interpupillary distance of the virtual reality helmet, and relates to the technical field of video and image display, in particular to virtual reality equipment with the adjustable interpupillary distance and an adjusting method. The method for adjusting the interpupillary distance of the virtual reality helmet comprises the steps of S200, an interpupillary distance detection module detects the interpupillary distance of a helmet wearer; S300, according to the interpupillary distance and the imaging relation of human eyes and a lens, a calculation module measures and calculates the sizes of a left screen display area and a right screen display area; 3400, according to a calculation result of the calculation module, a displayer displays the left screen display area and the right screen display area and the position in the display.

Description

technical field [0001] This patent application relates to the technical field of video and image display, and in particular to a virtual reality device with adjustable interpupillary distance and an adjustment method. Background technique [0002] Virtual reality (Virtual Reality, hereinafter referred to as VR) technology is based on intelligent computing equipment as the core, combined with sensing technology to generate a realistic virtual environment, through the system simulation of interactive three-dimensional dynamic vision and entity behavior through multi-source information fusion, users can Immerse yourself in that environment. [0003] There are two types of VR immersive experiences. One is angle-oriented immersive experience, which only includes 360° field of view rotation, which can be observed by freely rotating the body or head, such as the mobile phone box of GearVR; the other is The space-oriented immersive experience can not only realize 360° field of view...
