Virtual helmet lens interval adjusting method and device

Abstract

The invention relates to the virtual reality technology and discloses a virtual helmet lens interval adjusting method and device. The method is characterized by shooting human eyes through miniature cameras slantly arranged on lens frames respectively, and carrying out eyeball detection on the obtained human eyes to obtain eyeball positions in human eye images; and adjusting the positions of the lenses according to the obtained eyeball positions until the human eyes are overlapped with the center positions of the lenses respectively. The interval between the two lenses of a virtual helmet is allowed to be adjusted automatically according to the pupil distance of a user, so that the virtual helmet can be adaptive to pupil widths of different users automatically in the using process, and a best use experience is provided for the user.

Description

technical field [0001] The invention relates to virtual reality technology, in particular to a method for adjusting the distance between two lenses in a virtual helmet. Background technique [0002] The virtual helmet is a helmet-mounted stereoscopic display that uses people's left and right eyes to obtain information differences and guides users to produce a feeling of being in a virtual environment. The display principle is that the left and right eye screens display the images of the left and right eyes respectively, and the human eyes will generate a three-dimensional feeling in the brain after obtaining this information with differences. [0003] The principle of the virtual helmet is to enlarge the image produced by the small two-dimensional display through the optical system. Specifically, the light emitted by the small display passes through the convex lens so that the image is refracted to produce a similar distant effect. Use this effect to zoom in on nearby obje...

Problems solved by technology

[0005] The existing adjustment method is mainly manual adjustment, and the user generally needs to adjust it several times. After each adjustment, he wears a virtual helmet to try it out, so as to judge whether the distance between the lenses is appropriate. This operation method is cumbersome and complicated.

And for general users, it is difficult to judge the accuracy of the spacing, and it is difficult to accurately match the two lenses with the user's pupils, which affects the user's viewing effect

What's more, when some users or users are using it for the first time, due to the complexity of this adjustment method, they will directly use it without adjusting it, which will seriously reduce the user's comfort, thereby affecting the user's experience.
