Description
Technical Field
The invention belongs to the technical field of military exercises, and particularly relates to an immersive parallel training system.
Background
1. Army infantry virtual training
In 2011, the united states army took 5 years and cost 5700 ten thousand dollars to develop a DSTS (discrete Soldier Training System). And then updating and upgrading the system step by step according to VR technology development. By utilizing VR glasses, a firearm simulator and a leading CryEngine game engine, the system can build a full immersion type virtual environment with human-computer interaction effect, and can enable soldiers to carry out real combat simulation before putting into actual combat.
DSTS has certain limitations: firstly, the system must be used in a fixed place where a plurality of information acquisition devices are arranged; secondly, only 9 ginseng training can be supported at most; thirdly, the trainee can only move within the range of 10 feet by 10 feet (3.048m by 3.048 m); and fourthly, the VR training mode lacks a real scene.
2. Virtual shooting training system of New York police department
In 2019, in 4 months, hundreds of police officers in new york, usa tested VR virtual shooting training systems developed by V-Armed corporation and louisiana state university, which allowed multiple trainees to move in a large open space and experience various realistic scenarios through head displays, body sensors, and weapon props. Although this technology is currently being tested by the New York police department, it is likely to become a general training system for use by law enforcement nationwide.
The system relies on a commercial three-dimensional rendering engine to provide realistic VR visual images, sound effects, and other sensory experiences, and aims to bring the same mental and physical challenges as real situations, even to the trainee with a surge in epinephrine. As in the real world, trainees can shout each other or communicate through gestures. The commander can view the training from any angle at any time and then replay the picture for duplication.
Compared with DSTS, the system makes some progress, such as breaking through the limit of the number of trainees and the activity range of the trainees at the same time, and the trainees can move freely in a fixed place; however, the method still has the defects that the VR training mode is lack of reality when the method is used in a fixed place.
