Key Technologies Of Virtual Reality

The key technologies of virtual reality mainly include:

1. Dynamic environment modeling technology

The establishment of the virtual environment is the core content of the VR system. The purpose is to obtain the three-dimensional data of the actual environment, and establish a corresponding virtual environment model according to the needs of the application.

2, real-time 3D graphics generation technology

The technology of 3D graphics generation is relatively mature, so the key is to generate "real time". To ensure real-time, at least the refresh rate of the graphics is not less than 15 frames/second, preferably higher than 30 frames/second.

3, stereo display and sensor technology

The interactive ability of virtual reality depends on the development of stereoscopic display and sensor technology. The existing equipment can not meet the needs. The research of mechanics and tactile sensing devices needs to be further deepened. The tracking accuracy and tracking range of virtual reality devices also need to be improved.

4, application system development tools

The key to virtual reality application is to find suitable occasions and objects. Choosing the right application object can greatly improve production efficiency, reduce labor intensity and improve product quality. To achieve this goal, you need to study the development tools of virtual reality.

5, system integration technology

Since the VR system includes a large amount of sensory information and models, system integration technology plays a vital role. The integration technology includes information synchronization technology, model calibration technology, data conversion technology, data management model, identification and synthesis technology, etc. .
