Research and Design of VR Based Unmanned Aerial Vehicle Model and Database

: In response to the application of drones in real life, drones are more susceptible to interference and influence from various external factors such as weather, site, airspace, etc. during flight operations or related tasks. Not only can they not guarantee the completion of expected goals or tasks, but they are also prone to problems such as falling, collision, or accidental injury caused by the unstable state of drones. The drone flight simulation, virtual training, and drone database system developed based on VR technology has improved the safety, diversity, and instability of drones in practical applications, and reduced the interference of external adverse factors on drone flight. A comprehensive drone model database system has been established. This provides effective guarantees for the application and implementation of drones in various fields.


VR technology 2.1 VR Technology Concept
The concept of VR technology (Virtual Reality, also known as VR) is a practical technology developed in the 20th century. The earliest person to propose this concept was Jaron Lanier, the founder of VPL in the United States. VR is also known as "virtual reality" or "spiritual realm technology". The specific implementation is to use computer graphics systems and various display control interface devices to generate an interactive 3D environment on the computer, thereby creating a virtual world. Virtual reality has the characteristics of interactivity, imagination, and immersion, covering multiple disciplines such as computer software and hardware technology, robotics technology, sensing technology, artificial intelligence, and behavioral psychology. It is the ultimate manifestation and application form of multimedia. Virtual reality technology provides participants with simulated contact with visual, auditory, tactile, and other senses, allowing users to observe and experience things in 3D space in real-time without limitations.

Innovative scenarios for drone applications
Virtual reality technology can apply computers, software, and interactive peripherals to build virtual drone models and application scenarios, enabling people to complete drone control and execute various tasks as in real life . The virtual reality t e c h n o l o g y b a s e d o n the Internet provides a low-cost and convenient online drone learning and exploration environment for drone enthusiasts, providing innovative and reliable new ways for the research and application of drones in various fields. It can effectively promote the innovation and application development of drones in the field of virtual reality.

Has a wide range of applications
In traditional drone operations, it is difficult for different regions, departments, and projects to quickly fit together in a short period of time. The collaboration between different drones is poor, and the flexibility of the fit is low. It is extremely easy to encounter issues such as asynchronous data transmission, delayed reception, and ineffective cooperation among departments. By combining virtual reality technology with drone big data, the precise display of city level panoramic operation status and cooperation ability can break space and time constraints, achieve centralized management and resource optimization of regional drones, unified scheduling and remote control.

Has high flexibility
Traditional industrial drones have many limitations. In the military and industrial fields, they are often limited by issues such as size, affordability, and concealment. However, in daily use, they are also limited by environmental conditions, human interference, self-recovery ability, and other factors. When performing refined tasks, there are extremely high requirements for the technological level and accuracy of drones. By using virtual reality technology, in the system simulation of interactive 3D dyna mic scenes

Safe and efficient application practice process
Unmanned aerial vehicles are prone to accidents caused by uncontrollable personal use, and unexpected events may occur during industrial operations, resulting in property damage or personal injury, and may lead to secondary injuries. Using virtual reality technology, anticipate various possible emergencies in advance and conduct simulation exercises without considering aircraft explosions, casualties, and property losses. At the same time, the combination of virtual reality and drones can greatly improve the personal safety of participants in many dangerous and prone to casualties areas such as traffic patrols, urban patrols, counter-terrorism and riot prevention, urban and forest firefighting, reconnaissance and pursuit.

Effective cost savings
Drones themselves have high costs, and when used by individuals or teams, not only should their high cost be considered, but also their application scenarios, safety, and other issues. There are often problems such as high cost, single scenario, low reusability, and the vulnerability of unmanned aerial vehicles to damage. Using virtual reality technology to conduct homework exercises only requires consideration of initial investment, with almost zero cost in the later stages and no limitatio n on the number of training sessions. And there is no need to consider the cost of drones, as well as various component damage or updates and unexpected situations during the use of drones. Greatly reduces the potential losses and costs that may occur during the practical process.

The ground system can detect and receive telemetry information from the UAVs, thereby sending information commands to the UAVs. The UAVs then take actions based on the received commands. The training data testing and optimization system mainly collects, stores, analyzes and evaluates various data and problems that need to be generated during the execution of flight missions by drones, and continuously optimizes them to find the optimal solution for drone execution of various tasks and effectively avoid various problems that may arise in practice. It mainly includes three aspects: pre training data preparation, data collection during training, and post training data analysis optimization.

Conclusion
With the increasing development of science and technology, the application of unmanned aerial vehicles has become an important content in various fields. However, due to the vulnerability of drones to damage, high costs, and significant environmental factors, there are certain difficulties in the actual task training of drones. At the same time, there are also some bottlenecks in the development of drone technology.
