At present, science and technology have become an important step in the reform and development of sports, promoting the vigorous development of sports in our country. From the perspective of virtual computer technology, this paper applies virtual computer technology to modern training and designs a training system for volleyball players based on virtual reality technology. First, collect the sports data of the athletes, use the virtual reality perception interaction model to input the data into the virtual environment generation unit, perform data fusion under the control of the simulation management module, and combine the database in the sports simulation volleyball training data unit and the sports in the image card Behavioral interpretation, simulating 3D modeling based on User settings within the 3D Model Processor. The test results show that the system helps to improve the training effect of athletes, saves the cost of sports training, and has high practical application value.
