In time, the things in three dimensions is observed without limitation., can be to being physically present in real world in virtual environment
The local and imaginary world is simulated.Using display device, such as display screen or head mounted display, can show virtual
Environment.By display screen, virtual environment can be shown in three dimensions using 3D glasses.By head mounted display, use
Three-dimensional display can show virtual environment in three dimensions.
Visual plant of the virtual reality display system as game of future generation, virtual reality interaction, it is following in medical treatment, army
The field such as thing training and audio-visual amusement will be essential electronic equipment.But such system is still in developing stage, state at present
It is interior that there has been no the product of maturation.
The content of the invention
In order to solve above mentioned problem existing for prior art, the invention provides a kind of virtual reality display system, this is
System can provide virtual scene, allow user to realize the effect of experiencing virtual reality.
The technical solution adopted in the present invention is：A kind of virtual reality display system includes host computer, handle system and head
Head mounted displays, the head mounted display include head fixing device and the body-sensing being arranged in the head fixing device
Detection unit, single-chip microcomputer, video transmission module, left liquid crystal display and right liquid crystal display；The body-sensing detection unit detects user in real time
The acceleration and angular speed of head movement, and being transmitted by SPI interface to the single-chip microcomputer, the single-chip microcomputer is by the acceleration of reading
Degree and angular velocity signal are transmitted to the host computer, the host computer by USB interface is calculated the posture of user's head；Institute
State handle system to be connected with host computer, user controls the action of personage in virtual scene by the handle system；It is described upper
Machine produces corresponding virtual scene and transmitted by HDMI to the video transmission module, and the video transmission module is by people
Image transmitting to the left liquid crystal display and right liquid crystal display that eye can be shown in is shown.
