Optical lens structure of wearable virtual-reality headset capable of displaying three-dimensional scene

Abstract

The invention discloses an optical lens structure of a wearable virtual-reality headset capable of displaying three-dimensional scene. Two lenses of the left eye and the right eye are same in structure and both comprise double convex positive lenses and crescent negative lenses coaxially mounted at intervals. The double convex positive lenses close to the human eyes are mounted on a fixed temple, the crescent negative lenses are mounted on a movable temple, a guide rail is arranged on the inner wall of the fixed temple, and the movable temple is mounted on the guide rail movably. A display screen in front of the crescent negative lens is connected on the front portion of the fixed temple by a connecting frame, and the two lens structures are spaced by an intermediate partition. The two lenses are made of different kinds of optical plastics, and the optical surfaces of the front side and the rear side are aspheric surfaces. The optical lens structure can adjust diopter, a user can see the content on the screen without wearing glasses, chromatic aberration and distortion of the single lens are eliminated, the images inputted into a left screen and a right screen are not necessary to be preprocessed, image frames are improved and the user can see common left-right split-screen stereoscopic movies.

Description

Technical field [0001] The invention relates to an optical lens design with adjustable diopter, in particular to an optical lens structure of a wearable virtual reality helmet that presents a three-dimensional scene. Background technique [0002] Virtual Reality (VR) technology is a computer-generated, interactive, and immersive visual virtual environment proposed in the 1980s. It can generate a variety of virtual environments as needed and is widely used in urban planning. , Driving training, interior design and other fields. 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 enlarged screen through the eyepieces. For images, the sensor senses the changes of the human head to adjust the images on the left and right screens, so that the human eye can ...

Problems solved by technology

However, this method cannot solve the problem of blurred edge images, and will cause a drop in frame rate, which will bring dizziness to users

[0004] At present, there is still a problem that people with myopia generally cannot wear glasses when using virtual reality helmets. The general solution is to put the display screen close to the eyepiece, but the range of myopia that can be adjusted in this way is very limited, and generally can only be adjusted to 400 degrees of myopia. People who use it, and as the screen gets closer to the eyepiece, the pixels that the user can see will decrease, and the sense of immersion will decrease

[0005] Therefore, the structure of the eyepiece needs to take into account many factors, such as myopia range, interpupillary distance range, pupil size, acceptable deformation range, human eye resolution limit, screen size and resolution, etc., and there is currently a lack of a comprehensive consideration. and eyepiece lenses with good immersion
