Problems solved by technology

When adjusting the diopter, because the human eye prefers to see objects at close range, it is very likely that the observed image will be drawn very close, that is, the virtual image is very close, which will cause eye fatigue at close range

Embodiment Construction

[0044] In order to further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] refer to Figure 3 to Figure 5 .

[0046] Embodiment 1 of the present invention, such as Figure 4 As shown, the object distance is adjusted by adjusting the distance between the optical lens and the display screen. According to the above formula, when the display screen is at the focus of the optical system, the virtual image distance is infinite. When the distance between the adjustment lens and the display screen becomes smaller, the virtual image distance also gradually decreases, so that the virtual image can be imaged in the far point visible to the human eye, and then the position of the virtual image can be precisely adjusted as needed. The specific adjustment steps are as follows:

Abstract

The invention belongs to the technical field of virtual reality equipment, and particularly relates to a method for accurately adjusting a diopter of virtual reality glasses. According to a principle that pixels of different colors of a display element of the virtual reality equipment are located in the same optical system and are imaged at different positions in front of and behind a retina of each human eye through the human eye, a position relation between a virtual image position and a human eye visible far point is accurately adjusted according to different image sharpness of a sighting mark of a display screen; and a feedback mechanism is accurately provided through the difference of definition changes of the human eyes to different color pixels so that the human eyes are in a state of less adjustment, the refraction load of the human eyes is reduced, and the burden of ciliary muscles is decreased. And the method enables the human eyes to relax while a virtual reality glasses device is applied, and the purpose of protecting the eyes is achieved.

Description

technical field [0001] The invention belongs to the technical field of virtual reality equipment, and in particular relates to a method for precisely adjusting the diopter of virtual reality glasses. Background technique [0002] Virtual Reality (Virtual Reality) glasses equipment or Augmented Reality (Augmented Reality) glasses equipment are devices that rely on optical technology and computer image technology processing methods. The former can create a completely virtual and immersive image scene that is out of reality, and the latter can Generate images and information superimposed on real-world scenes. These two (hereinafter collectively referred to as virtual reality devices) are very popular research application fields and directions in recent years, and are considered to be the next generation of mobile terminal devices. [0003] In recent years, due to the popularization of electronic devices, the rate of myopia in the population has gradually increased, and the vis...
