Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1 is a flowchart illustrating a method for protecting safety in a virtual reality game according to an exemplary embodiment, where as shown in fig. 1, the method for protecting safety in a virtual reality game is used in a safety protection device in a virtual reality game, where the safety protection device in a virtual reality game may be specifically a television, a PC, a game machine, and the like, and the method for protecting safety in a virtual reality game includes the following steps.

In step S11, the position of an object within the shooting range of the camera and the body feature information of the user are acquired.

In this embodiment, a camera needs to be installed on the safety protection device in the virtual reality game, and the type of the camera is not limited, for example, a termite camera, a camera carried by a PC, and the like. After a user starts a virtual reality game, the camera can automatically acquire an image in a shooting range, the shot image comprises an object and a user in the shooting range, then the object and the person in the shooting range are identified according to the image, and the position of the object in the shooting range and the body characteristic information of the user are determined. Wherein the physical characteristic information of the user comprises at least one or a combination of the following information: the height of the user, the length of the legs, and the length of the arms.

In step S12, the limb movement that the user needs to perform within the preset time is acquired.

After the virtual reality game starts, the body motions of the user within a preset time may be periodically acquired according to a preset period, for example, the body motions are acquired every 5 seconds, and then the preset time is 5 seconds, after the virtual reality game starts, the body motions that the user needs to perform within 1 second to 5 seconds are acquired at 1 st second, then the body motions that the user needs to perform within 6 seconds to 10 th second are acquired at 6 th second, and so on, and the body motions of the user are acquired in units of 5 seconds.

In step S13, an initial position of the user within the shooting range is acquired, the initial position being a position of the user at a start time of a preset time.

The initial position of the user in the shooting range is obtained according to the image by acquiring the image of the user at the starting moment of the preset time, for example, the preset time is from 1 st second to fifth second, and then the initial position is the position of the user at the 1 st second.

In step S14, the movement range of the user when performing each limb movement is calculated according to each limb movement of the user within a preset time, the initial position and the body characteristic information.

After the initial position of the user is determined, the moving direction of the user can be determined according to the limb actions of the user, for example, the user wants to perform a jumping movement to the left in the first second, then the moving direction of the user can be determined as the leftward movement according to the limb actions of the user, after the moving direction is determined, a moving distance needs to be determined, and the moving distance is related to the limb actions and characteristic information of the user, for example, the size of a jumping step for an adult with the height of 1.8 m is greatly different from the size of a jumping step for a child with the height of 0.8 m, and therefore, the maximum moving distance of the user in the moving direction needs to be determined according to the limb actions and the characteristic information of the user. For example, for a jump left motion, the maximum movement distance for the user to jump left is determined based on the height and/or leg length of the user. Since the user itself also occupies a certain space and the user may have some deviation when performing a certain limb movement, for example, for a jumping movement to the left, the user is not necessarily along the right left direction, and may move a little bit forward or backward, the initial position, the moving direction and the maximum moving distance of the user need to be considered when determining the moving range, and these factors need to be considered in order to determine a more accurate and reasonable moving range, and the moving range of the user is a three-dimensional space.

In step S15, it is determined whether the user has collided with the object in the photographing range while performing each limb movement, based on the movement range of the user while performing each limb movement and the position of the object in the photographing range.

In one implementation manner, whether the moving range of the user in the first body movement is overlapped with the position of the object in the shooting range is judged, and if the moving range of the user in the first body movement is overlapped with the position of the object in the shooting range, it is determined that the user collides with the object in the shooting range in the first execution movement. Alternatively, if the movement range of the user when performing the first body motion does not overlap with the position of the object in the imaging range, it is determined that the user does not collide with the object in the imaging range when performing the first body motion. Here, the first limb movement is not particularly limited to any one limb movement, and the first limb movement is any one of limb movements that need to be performed within a predetermined time.

In step S16, if the user collides with an object in the imaging range while performing any one of the body movements, a prompt message is issued to avoid the user from colliding.

In this embodiment, the prompt message may include only text message, only voice message, or both text message and voice message. The user is prompted through the text information and the sound information that collision is possible when a certain action is executed, and the user adjusts the position of the user according to the prompt information, so that collision is avoided.

According to the safety protection method in the virtual reality game, the position of an object in the shooting range of a camera, the body characteristic information of a user, the body actions required by the user in the preset time and the initial position of the user at the starting moment of the preset time are obtained, then the moving range of the user in the process of carrying out each body action is determined according to each body action, the initial position and the body characteristic information of the user in the preset time, further, whether the user collides with the object in the shooting range when carrying out each body action is determined according to the moving range of the user in the process of carrying out each body action and the position of the object in the shooting range, and if the collision happens, prompt information is sent. By sending prompt information to the user, the user can be prevented from colliding with objects in the shooting range.

Fig. 2 is a flowchart illustrating a method for security protection in a virtual reality game according to another exemplary embodiment, and this embodiment explains in detail a manner of determining a moving range of a user when performing each limb action on the basis of the embodiment illustrated in fig. 1. As shown in fig. 2, the method for protecting safety in a virtual reality game of the present embodiment includes the following steps.

In step S201, the position of an object within the shooting range of the camera and the body feature information of the user are acquired.

In step S202, the limb movement that the user needs to perform within the preset time is acquired.

In step S203, an initial position of the user within the shooting range is acquired, the initial position being a position of the user at a start time of a preset time.

In step S204, a three-dimensional coordinate system is established with the initial position as the origin.

The direction of the X-axis of the three-dimensional coordinate system is the left side of the user, -the direction of the X-axis is the right side of the user, -the direction of the Y-axis is in front of the user, -the direction of the Y-axis is behind the user, the direction of the Z-axis is perpendicular to the ground upwards, -the direction of the Z-axis is perpendicular to the ground downwards. Or the direction of the X axis is the right side of the user, -the direction of the X axis is the left side of the user, the direction of the Y axis is the back of the user, and the direction of the-Y axis is the front of the user.

In step S205, the maximum moving distance of the user in each direction of the three-dimensional coordinate system when performing each limb action is determined according to each limb action and the body feature information.

Taking the example that the user jumps from the initial position to the left, then the maximum moving distance in the directions of the X-axis, the Y-axis, the-Y-axis, and the Z-axis of the three-dimensional coordinate system is greater than 0, and the maximum moving distance in the directions of the-X and-Z-axes is 0. The maximum moving distance in the X axis, the Y axis, the-Y axis and the Z direction is determined according to the limb action and the body characteristic information of the user.

In step S206, a cube made up of the maximum movement distances in the respective directions of the three-dimensional coordinate system when the user performs each limb movement is determined as the movement range of the user when performing each limb movement.

For each limb pass, after determining the maximum moving distance of the user in each direction of the three-dimensional coordinate system when the user performs the limb action, the maximum moving distance in each direction of the three-dimensional coordinate system forms a cube, and the space occupied by the cube is the moving range of the user when the user performs the limb action.

In step S207, it is determined whether the user collides with the object in the photographing range when performing each body motion, based on the movement range of the user when performing each body motion and the position of the object in the photographing range.

In this embodiment, the position of the object in the shooting range is also a cube formed by the space occupied by the object, so that the cube formed by the maximum moving distance of the user in each direction of the three-dimensional coordinate system when performing each body motion can be compared with the cube formed by the space occupied by the object in the shooting range, and if there is overlap between the two cubes, it is determined that the user collides with the object in the shooting range when performing a certain body motion. If there is no overlap between the two cubes, it is determined that the user does not collide with an object within the photographing range when performing a certain action.

In step S208, if the user collides with an object in the imaging range while performing any one of the body movements, a prompt message is issued.

In this embodiment, the position of an object within a shooting range of a camera, the body characteristic information of a user, the limb actions required by the user within a preset time, and the initial position of the user at the starting time of the preset time are obtained, then, a three-dimensional coordinate system is established with the initial position as an origin, the maximum moving distance of the user in each direction of the three-dimensional coordinate system when executing each limb action is determined according to each limb action and the body characteristic information, and a cube formed by the maximum moving distances of the user in each direction of the three-dimensional coordinate system when executing each limb action is determined as a moving range. And further determining whether the user collides with the object in the shooting range when executing each limb action according to the moving range of the user when executing each limb action and the position of the object in the shooting range, and if so, sending prompt information. By sending prompt information to the user, the user can be prevented from colliding with objects in the shooting range.

As shown in fig. 3, the method for protecting safety in a virtual reality game of the present embodiment includes the following steps.

In step S301, a game start instruction is received.

The game starting command is input by a user through an input device, for example, the user clicks a game starting button with a mouse or a finger, and after the user clicks the starting button, the safety protection device in the virtual reality game receives the game starting command.

In step S302, a camera is started to capture images of an object and a user within a shooting range according to a game start instruction.

The safety protection device in the virtual reality game can automatically start the camera after receiving a game starting instruction.

In step S303, the position and body feature information of the object within the shooting range are determined from the shot image.

In step S304, the limb movement that the user needs to perform within the preset time is acquired.

In step S305, an initial position of the user within the shooting range is acquired, the initial position being a position of the user at a start time of a preset time.

In step S306, a movement range of the user in performing each limb movement is determined according to each limb movement, the initial position and the body characteristic information of the user within a preset time.

In step S307, it is determined whether the user collides with the object in the photographing range when performing each limb movement, based on the movement range of the user when performing each limb movement and the position of the object in the photographing range.

In step S308, if the user collides with an object in the imaging range while performing any one of the body movements, a prompt message is issued.
