Embodiment 1

[0027] Embodiment 1 of the present invention: a method for virtual reality walking control based on inertial sensors, such as figure 1 shown, including the following steps:

[0028] S1, using inertial sensors to track the orientation and posture of the human torso;

[0029] S2, obtain the orientation and attitude angle of the current human torso by calculating the integral of the angular velocity value of the gyroscope in time (specifically, at first, the gyroscope can obtain the direction perpendicular to the ground by means of the magnetometer to measure the earth's magnetic field; Secondly, the gyroscope can measure the angular acceleration value, and the angular velocity value can be obtained by integrating the angular acceleration value in time; again, the angular value can be obtained by integrating the angular velocity value in time; finally, the angular value and Comparing the previously obtained direction perpendicular to the ground, the orientation and attitude angl...

Embodiment 2

[0032] Embodiment 2: a kind of method that carries out virtual reality walking control based on inertial sensor, comprises the following steps:

[0033] S1, using inertial sensors to track the orientation and posture of the human torso;

[0034] S2, use the acquired human torso orientation to control the moving direction of the virtual world characters; at the same time, use the obtained attitude angle to control the walking action of the virtual world characters—use the forward, backward, left, and right inclinations of the human torso to control the virtual world in one-to-one correspondence The character's forward, backward, leftward translation, rightward translation; and use the forward tilt angle, backward tilt angle, left tilt angle, right tilt angle of the human body to control the forward speed, backward speed, and leftward translation speed of the virtual world character in one-to-one correspondence , right pan speed.

Embodiment 3

[0036] Embodiment 3: a kind of method that carries out virtual reality walking control based on inertial sensor, such as figure 1 So, include the following steps:

[0037] S1, using inertial sensors to track the orientation and posture of the human torso;

[0038] S2. Obtain the orientation and attitude angle of the current human torso by calculating the integral of the angular velocity value of the gyroscope in time; use the acquired orientation of the human body torso to control the moving direction of the virtual world character; at the same time use the obtained attitude angle to control the walking of the virtual world character action.

[0039] A system for implementing the above method based on inertial sensors for virtual reality walking control, such as figure 2 As shown, it includes: an inertial sensor 1 and a computing control platform 2. The inertial sensor 1 is connected to the computing control platform 2. The inertial sensor 1 is used to track the orientation...

Abstract

The invention discloses a virtual reality walking control method and system based on an inertia sensor. The method comprises the following steps: S1, tracking the orientation and the attitude of a human trunk by use of the inertia sensor; and S2, controlling the movement direction of a virtual world figure by use of the obtained orientation of the human trunk, and at the same time, controlling the walking motion of the virtual world figure by use of an obtained attitude angle. According to the invention, a strong dizzy feeling brought to a user by the difference between visual perception and body perception is overcome; at the same time, a whole device is small in size (far smaller than an omnidirectional mobile platform, a treadmill and a space motion capture device) and is quite low in price, thereby being suitable for household consumption and entertainment; and besides, walking control is performed on the virtual world figure by use of the technology provided by the invention, special restrictions are eliminated, movement of any distances in random directions in a virtual reality world can be realized.

Description

technical field [0001] The invention relates to a method and system for virtual reality walking control based on an inertial sensor, and belongs to the technical field of virtual reality. Background technique [0002] In a virtual reality environment, users need to move and roam in the virtual world. The common methods of mobile control are as follows: [0003] 1. Direction control buttons: The user controls the direction and speed of movement by controlling the buttons, joysticks, etc. on the handle, keyboard buttons and other equipment. This method is cheap and reliable, but after the user wears the head-mounted display device, he has a highly immersive visual experience. When using the buttons to control movement and steering, the vestibular organ that perceives the motion state of the body does not perceive the corresponding movement. The difference between perception and physical perception will bring a strong sense of dizziness to the user; [0004] 2. Omni-direction...
