1. Highly realistic 3D underground environment

Utilizes 3D scanning and model reconstruction technology to achieve high-precision restoration of underground scenes and facilities.

2. Realistic simulation of operational tools

Employs physical scanning and photogrammetry techniques to accurately present actual operational tools in the virtual environment.

3. Physical effects simulation

Simulates physical effects such as gravity and collision of tools, making operations more lifelike.

4. Interactive operation

Supports hand tracking, allowing users to operate tools with virtual hands to complete various tasks.

5. Process recording and evaluation

Records every step of the trainee's operations in the virtual environment, providing automatic scoring and prompts.

6. Multi-angle observation and assessment

Offers multiple perspectives to observe the trainee's operation process, enabling evaluation from different angles.

7. Operational data analysis

Collects training data from all trainees and performs algorithmic analysis to derive operational models.

8. Pattern recognition and comparison

Uses pattern recognition technology to compare differences between trainee operations and expert operations.

9. Operation diagnosis and suggestions

Intelligently analyzes operational steps and provides targeted diagnostics and skill improvement recommendations.

This system can effectively enhance the quality of underground operation training and reduce safety risks.

System Features:

1. User login and permission authentication;

2. The system includes training mode and assessment mode. In assessment mode, the system can submit user assessment results to the backend management system;

3. Supports user interaction with virtual equipment in the virtual environment using VR controllers;

4. Allows users to navigate the system using controller operations;

5. The system supports text and voice prompts for operations;

The system enables six degrees of freedom (6DoF) interactive operations with VR controllers in a realistic 3D environment.

Technical Approach:

The system is developed using the Unreal Engine, leveraging PBR materials to create a realistic virtual reality representation of the underground working environment. Particle systems are used to simulate effects such as water spraying and dust during operations.
