In step S101, a start point position, a destination position, vehicle information, and body information of a target person are acquired. The start point position, the destination position, the vehicle information, and the body information may be acquired through voice input. For example, by means of keywords and data, the "door of the market at the starting point a", "iron notch at the destination B", "car C", and "height 175 cm", wherein the default current position is not input at the starting point position, and the current position can be obtained by the positioning system. The information can be obtained through key input, option selection and the like.
In step S102, route information is acquired according to the starting point position and the destination position, and a virtual reality image corresponding to the route information is acquired according to the route information.
The route information is automatically acquired according to the starting point position and the destination position, and the route information comprises different types of modes such as shortest distance, fastest arrival and the like, and can also be divided into whether the route information comprises an expressway. And then acquiring a virtual reality image corresponding to the route information according to the route information. All virtual reality images corresponding to the route information can be downloaded, or only the virtual reality image of the initial point position and the first part of the route information can be downloaded, and then the virtual reality image corresponding to the next section of the route is obtained in real time according to the change of the virtual position.
In step S103, a gaze focus and a display range are acquired from the vehicle information and the body information.
Specifically, the vehicle information includes vehicle type information and seat height information; the vehicle type information comprises a common car, an SUV (sports utility vehicle), an off-road vehicle, trucks of different models and the like, and can also comprise corresponding brands and specific models, the vehicle type information can be acquired by receiving manual input of a user, and multi-level options can be provided for the user to select and acquire. After the specific model information is acquired, the chassis height, the seat height, the size and angle height of the front window glass and the size and angle height of the side window glass of the vehicle are acquired corresponding to the model information. But may also include top speed, launch rate, etc.
The body information includes head position, height difference information of eyes and seats, and gazing direction. The position of the eyes in the vehicle is determined by the head position and the height difference information of the eyes and the seat, and the position comprises height, angle and the like.

According to the embodiment of the invention, because different vehicles selected by different users are different, the heights of the users are different, and the actual driving pictures are different, the specific virtual reality image is provided for different vehicle information and body information, and the reality of driving simulation is improved. For example, for a user with a high height, the position of eyes is higher than that of a vehicle window, and in addition, the height of a vehicle chassis is higher, images obtained through the vehicle window are richer than those below other users, and the number of images above the vehicle window is less, so that the requirements of actual driving are better met. When the vehicle is initially learned, a user can adapt to the real vehicle more easily, the fear of driving is overcome easily in the initial on-road stage, the user can be familiar with road conditions first, the user is not easy to be nervous, and the adaptation period is shortened.
Further, the adjusting the display content of the virtual reality image according to the gaze focus and the display range includes:
the virtual reality image comprises a first display image within a first distance of the watching focus and a second display image beyond the first distance of the watching focus, and the definition of the first display image is adjusted to be higher than that of the second display image.

The emphasis is given to the user. The first distance can be adjusted according to the distance of the gazing focus, and the first distance can be adjusted according to the proportion of the display content of the virtual reality image, for example, half of the display content is the first display image, and the other parts are the second display images by taking the gazing focus as the center. Similarly, display images with several definition levels can be set, for example, a first display image within a first distance of a focus of attention is an ultra-high definition image, a second display image within a second distance beyond the first distance of the focus of attention is a high definition image, and a third display image beyond the second distance of the focus of attention is a standard definition image. It should be noted that not only the ranges of two-level and three-level definitions can be set, but also ranges of more levels of definitions can be set, such as four levels, five levels, six levels, and the like.
