Abstract

Embodiments of the invention provide a focal length control device and method and VR glasses. The device includes a focal length measuring module, a focal length changing module and a rendering module. The focal length control device measures the focal length value of human eyes through the focal length measuring module, and sends the focal length value to the focal length changing module and the rendering module. The focal length changing module controls the focal length of the device according to the received focal length value of the human eyes. The rendering module is used to perform fuzzy processing on a display image according to the received focal length value of the human eyes. The focal length control device uses the focal length measuring module, the focal length changing module and the rendering module to put the human eyes' focal length, a 3D screen and a display in the same plane and create a depth-of-field effect, so that the display screen is more in line with the actual scene seen by the human eyes, and the dizziness due to the vergence-accommodation conflict of human eyes is alleviated.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of virtual reality, and in particular to a focus control device, method and VR glasses. Background technique [0002] Virtual Reality (English: Virtual Reality, referred to as: VR) technology is an important direction of simulation technology, VR display is to use the head-mounted display device to close people's vision and hearing to the outside world, and guide users to create a feeling of being in a virtual environment. in the feeling. [0003] The VR display adopts a binocular stereo vision display mode, and a fixed focal length is set so that different images seen by the user's two eyes are displayed on different displays. A three-dimensional sense is created in the brain after different information, and the image is imaged in space by using the convergence of the eyes (that is, when the eyes stare at an object that moves closer to the front, the pupils constrict and the eyes ...
