Head mounted display
The invention discloses a head mounted display which comprises a main frame, a perspective type optical display system, a main control system and a binocular three-dimensional visual system. The perspective type optical display system comprises an image display module, an optical amplification system and a fine adjusting mechanism. The binocular three-dimensional visual system shoots a target object in front of the human eyes and acquires the distance between the target object and the human eyes through a parallax principle distance measuring method. The main control system controls the perspective type optical display system to automatically adjust the distance from the virtual image to the human eyes according to the obtained distance from the target object to the human eyes, therefore, the comfortableness of eye using when a user uses image displayers is ensured, and eyestrain can be relieved. Further, in the augmented reality application, when the depth of field changes, the distance between the virtual image and the human eyes is adjusted automatically to enable the virtual image to fit with the actual environment, the enhanced display effect can be truly achieved, and user experience can be enhanced greatly.
