Driving simulator with stereoscopic vision follow-up function

Abstract

The invention relates to a driving simulator with a stereoscopic vision follow-up function. The driving simulator comprises a computer, a simulated driving platform, a projector and a vision follow-up device, wherein the computer is provided with driving simulation software, an output signal of the simulated driving platform is input to the computer, the vision follow-up device comprises a sight monitoring device, a rotating holder and a stepping motor which is used for driving the rotating holder to rotate, the sight monitoring device comprises a rotating-angle sensor which is used for monitoring the head rotation of a driver, an output signal of the sight monitoring device is input to the computer, the projector is arranged on the rotating holder, the stepping motor is controlled by the computer, and the output signal of the sight monitoring device can be used for changing an angle between a virtual camera and a virtual vehicle through the computer. According to the driving simulator disclosed by the invention, stereoscopic vision is supplied for the driver in the driving simulator, and the stereoscopic vision is not in distortion.

Description

[0001] technical field [0002] The invention relates to a driving simulator, in particular to a driving simulator with visual follow-up function. Background technique [0003] At present, stereoscopic movies use vision to shoot the scene from the perspective of the photographer, but in the simulator, the driver is in the simulated cab, constantly moving, and the vision is constantly changing. The objects seen by the driver have different visual differences, but the fixed simulation The utensil has the same visual difference to all object visions, if the fixed vision is adopted, a better three-dimensional effect cannot be achieved. Due to the visual rotation of the human vision during the observation process, the change of the pupil focal length leads to the change of the observation distance. The present invention uses the sensor to track the driver's head movement and the change of the focus of the pupil to adjust the visual angle difference of the visual image and improve...

Problems solved by technology

At present, the simulated driver method is used to experience the driving simulation, but the stereo vision used is to use the front as the visual object, resulting in an immersive body mechanics perception effect that is not realistic enough.

Compared with ordinary monocular vision simulators, the user's left and right eyes see two plane images with parallax, and synthesize them in the brain to generate stereoscopic vision perception, which can enhance the reality of the virtual environment. Stereoscopic display technology , but if the head moves, the visual objects of the two eyes change, and the visual vanishing point also changes. If the visual objects and visual vanishing points are fixed in the process of simulating a 3D image, the stereoscopic vision will be obtained distortion
