Background technique

Virtual reality technology is a virtual world that can be created and experienced. Users generate a simulated environment through a simulation system. This environment has an interactive three-dimensional environment generated by a multi-resource information fusion technology such as a computing graphics system and a hardware system, that is, a virtual environment.

With the development of social economy, computers have become an important part of people's lives, and man-machine interface technology has become an important subject that people care about. Therefore, in recent years, virtual reality technology has become the focus of people's attention. It has been widely used in urban planning and construction and brought significant benefits, so as to show the immersion and interaction of the virtual reality system of the planning scheme, and the user can feel the scene in the experience process. Realistic and lifelike feeling impact, or immersive feeling, real-time access to relevant information of the project in the virtual environment through the data interface, so it is convenient for large-scale engineering planning and design, and it is beneficial for managers to assist in the design and planning of various schemes Evaluate.

At present, with the popularization of vehicles, each of us needs to master driving skills. In the existing technology, the use of the steering wheel to actually operate the vehicle for driver's license assessment or driving drills has become more and more backward, which not only wastes the user's time and experience, but also has insufficient training facilities. Perfect, so we need to use virtual reality technology for driving drills, so that users can achieve good driving of the vehicle in a short time.

Scene construction unit: provide logic simulation models and functional modules for the driver in the vehicle, the scene construction unit at least includes a virtual reality helmet that the driver needs to wear, and the scene construction unit has a graphics unit with dynamic elements in the VR virtual scene ;

VR virtual scene realization unit: based on VR technology, the graphics unit in the scene construction unit is read to generate a simulation model and an operation simulation space for driver training, and the driver wears a virtual reality helmet for driver's license examination and drill simulation; the scene construction unit Real-time data communication with data storage unit and VR virtual scene realization unit respectively;

The motion tracking module is used in the virtual reality helmet to carry out real-time positioning tracking and recording of the driving state of the car and the driver's operating state. The phase relationship of the surface displacement transmits the information to the data storage unit, and the data storage unit checks the data information with the correct emergency action information stored in it, and judges and counts whether the error range of the two is within the set value. If it is within the set range, the emergency action of the driver has passed the examination.

Preferably, the motion tracking module uses a three-axis gyroscope and a displacement sensor

Preferably, a verification module is arranged in the data storage unit.

Due to the adoption of the above technical solution, the present invention provides a vehicle driving training and assessment system based on virtual reality technology. The user enters the vehicle and puts on a virtual reality helmet, turns on the system for training mode, and the scene construction unit provides the VR virtual scene. The graphics unit of the dynamic elements, through the VR virtual scene realization unit, simulates the virtual reality space. During the process, the driver experiences a variety of driving assessment situations, and at the same time, the driver's gestures and foot movements respond accordingly. , the data storage unit judges the driver's action response based on the actual action and the action stored in it, and all the processes of the system are realized based on virtual reality technology, which eliminates the actual operation process in the actual driver assessment process and saves manpower physical resources.
