Embodiment 1

The embodiment provides a steering control method for adjusting scene information that a target object faces in a virtual scene. As shown in FIG. 1, the steering control method of this embodiment includes:

S101. After receiving the steering triggering instruction, determine, according to the position of the target object in the real scene and the steering angle indicated by the steering triggering instruction, the position of the target object in the virtual scene after the steering position is turned according to the steering angle;

S102. Adjust the scene information that the corresponding character faces in the virtual scene according to the position of the target object in the virtual scene according to the steering angle.

In this embodiment, the target object may be a person, such as a controller of a virtual game. In an exemplary embodiment, the target object changes the scene information in the seen virtual scene by moving in a real scene; or, in the virtual scene, there is a character corresponding to the target object, and the target object is in the real scene. Motion control corresponds to the movement of the character in the virtual scene.

In this embodiment, when the steering triggering command is received, the position of the user in the real scene does not need to be turned, and only the position of the character corresponding to the user in the virtual scene needs to be adjusted, so that the user turns to the corresponding character in the virtual scene. , causing the user to turn through the scene that the corresponding character sees in the virtual scene.

In this embodiment, the position of the target object in the real scene can be determined by the positioning device. The positioning device may adopt a binocular positioning method or a laser positioning method, which is not limited in this application.

Wherein, at least two positioning devices may be disposed on the target object. At least two positioning devices are arranged at different positions on the target object. For example, taking the target object as the controller of the virtual game as an example, the two positioning devices can be respectively the handle locator, and the two handle locators can be respectively held by the left and right hands of the virtual game controller; or, two positioning The device can be a handle locator and a head locator respectively. The handle locator can be held by one hand of the virtual game controller, and the head locator can be worn on the head of the virtual game controller. However, this application is not limited thereto.

In an exemplary embodiment, the number of positioning devices may be three, one of which may be mounted on the head mounted display device, and the other two positioning devices may be mounted on the two handles, respectively. In this way, the user can grasp the position of the real scene by holding the two handles and wearing the head.

Wherein, the positioning device can determine the position in the real scene by the positioning signal transmitted by the receiving signal transmitter (for example, the signal transmitting base station). For example, a preset spatial coordinate system can be determined in a real scene. In an example, taking the signal transmitter as a cuboid, the origin of the preset space coordinate system may be the center of gravity of the signal transmitter, and the first coordinate axis (for example, referred to as the X axis) may be perpendicular to the side panel of the signal transmitter. The second coordinate axis (for example, referred to as the Z axis) may be perpendicular to the front panel of the signal transmitter, and the direction pointing to the front side of the front panel is the positive direction of the second coordinate axis, the positive direction of the first coordinate axis and the second coordinate axis The positive direction satisfies the right hand rule, and the third coordinate axis (for example, the Y axis) is perpendicular to the plane defined by the first coordinate axis and the second coordinate axis. There are a plurality of ways for setting the preset space coordinate system, which is not limited in this application. In practical applications, the preset spatial coordinate system can be determined according to the actual situation of the actual scene and the positioning method adopted.

In the above example, the positioning signal transmitted by the signal transmitter may include: a first laser plane signal, a second laser plane signal, and an ultrasonic signal. Wherein, the first laser plane signal and the second laser plane signal are rotated and emitted, and the rotation axes of the two may be perpendicular to each other. The signal transmitter can transmit a synchronization signal, an ultrasonic signal, a first laser plane signal, and a second laser plane signal in each signal period. The positioning device can obtain the time of receiving the synchronization signal, the time of receiving the laser plane signal, and the time of receiving the ultrasonic signal according to the time of receiving the signals, and the corresponding algorithm can be used to calculate the positioning device in the preset space coordinate system. coordinate.

Wherein, S101 can include:

Determining, according to the coordinates of the at least two positioning devices in the real scene and the steering angle, the coordinates of the at least two positioning devices in the virtual scene after the corresponding object in the virtual scene is turned according to the steering angle.

In this embodiment, the preset spatial coordinate system (hereinafter referred to as the first coordinate system) in the real scene in which the target object is located may be identical or different from the spatial coordinate system (hereinafter referred to as the second coordinate system) in the virtual scene. When the first coordinate system and the second coordinate system are inconsistent, there may be a conversion relationship between the two. That is, the coordinates in the first coordinate system can obtain the corresponding coordinates in the second coordinate system by the conversion relationship.

When the first coordinate system and the second coordinate system are coincident, the position in the virtual scene, that is, the coordinates in the second coordinate system, can be determined according to the coordinates of the positioning device in the first coordinate system.

When there is a conversion relationship between the first coordinate system and the second coordinate system, according to the coordinates of the positioning device in the first coordinate system and the above conversion relationship, the position of the positioning device in the virtual scene can be obtained, that is, in the second coordinate system. The coordinates in .

Taking two positioning devices D1 and D2 as an example, the coordinates of the positioning device D1 in the first coordinate system when receiving the steering trigger command are used as the replacement origin; according to the replacement origin and the steering angle, it is determined that the target object is in the first coordinate system. After the steering is performed, the coordinates of the two positioning devices D1, D2 in the first coordinate system; when the first coordinate system is consistent with the second coordinate system in the virtual scene, determining that the positioning devices D1, D2 are in the first coordinate system The coordinates are the coordinates of the two positioning devices D1 and D2 after the target object is turned in the corresponding character in the virtual scene. For example, when the steering angle is 180 degrees, after the steering, since the coordinates of the positioning device D1 are the replacement origin, the coordinates of the positioning device D1 are unchanged, and the coordinates of the positioning device D2 become the replacement origin with the coordinates of the positioning device D1. The position after turning to the degree. When the first coordinate system is inconsistent with the second coordinate system in the virtual scene, the coordinates of the assumed target object in the real scene may be calculated according to the coordinates of the positioning device D1 and D2 in the first coordinate system, and then the coordinates are calculated. The coordinate is obtained according to the conversion relationship mapping to obtain the coordinates of the positioning devices D1 and D2 in the virtual scene; or, the positioning device D1 can be calculated according to the coordinates of the positioning device D1 and D2 in the first coordinate system and the conversion relationship between the two coordinate systems. D2 is the coordinate in the second coordinate system in the virtual scene, and then the coordinates of the positioning devices D1, D2 are steered in the second coordinate system to obtain the coordinates after the steering. However, this application is not limited thereto.

In an exemplary embodiment, S101 may further include:

Determining, according to the coordinates of the at least two positioning devices in the real scene and the steering angle, the posture of the at least two positioning devices in the virtual scene after the corresponding object is turned according to the steering angle in the virtual scene.

In an exemplary embodiment, after S102, the method of the embodiment may further include: when the target object moves in the real scene, according to the coordinates of the at least two positioning devices in the real scene when the target object is in the real-time position, receiving Determining the coordinates of at least two positioning devices in the virtual scene when the target object is in the real-time position by the coordinates and the steering angle of at least one of the at least two positioning devices when the triggering command is turned. In this example, the scene information of the target object in the virtual scene may be further adjusted according to the coordinates of the at least two positioning devices in the virtual scene when the target object is in the real-time position. That is, according to the real-time moving coordinates of the target object in the real scene, the scene information that the target object faces in the virtual scene is dynamically adjusted.

After the target object is turned in the corresponding character in the virtual scene, the target object in the virtual scene is rotated because the target object does not turn in the real scene, so that the scene after the target object is turned to the target object can be seen.

Wherein, when the target object is steered in the virtual scene corresponding character, when the target object moves, if the first coordinate system and the second coordinate system are consistent, the coordinates of the positioning device in the first coordinate system may be changed according to the target object and The initial displacement origin determines the coordinates of the positioning device in the second coordinate system after the target object is turned.

If the first coordinate system and the second coordinate system are inconsistent, the coordinate of the positioning device in the first coordinate system and the replacement origin may be first calculated, and the coordinates of the positioning device in the first coordinate system after the target object is turned in the real scene are calculated. Then, the coordinate is mapped according to the conversion relationship to obtain the coordinates of the positioning device in the second coordinate system in the virtual scene; or, the positioning device in the virtual scene may be calculated according to the coordinates and the conversion relationship of the positioning device in the first coordinate system. The coordinates in the second coordinate system are then steered by the coordinates of the positioning device in the second coordinate system of the virtual scene to obtain the coordinates after the steering. However, this application is not limited thereto.

The steering control method of the present embodiment can be applied to head display or to a control device independent of the head display and the handle. However, this application is not limited thereto.

In an exemplary embodiment, a steering trigger button may be provided on the handle, or a steering trigger button may be provided on the head display, and the user may press the steering trigger button when a scene requiring the user to turn around occurs. For example, when the steering trigger button on the handle is pressed, the handle can send a steering trigger command to the head display or control device.

In an exemplary embodiment, depending on the steering angle, a plurality of steering trigger buttons may be correspondingly disposed on the handle or the head, or a combination button may be set on the handle or the head to allow the user to set the steering angle.

In an exemplary embodiment, the steering angle may be 180 degrees, however, this application is not limited thereto. In practical applications, the steering angle that needs to be processed by the solution of the present application may be set according to actual conditions, for example, the steering angle may be greater than 180 degrees.

It should be noted that, in this embodiment, taking a steering angle of 180 degrees as an example, after the target object performs a 180 degree turn in the corresponding character in the virtual scene, in the virtual scene, the target object corresponds to the scene facing the character. In addition to the positional shift, the attitude also has a 180 degree rotation.

The solution of the present application will be described below by way of an example.

In this example, the target object is the user, and the number of positioning devices is three, one of which is mounted on the head display and the other two are mounted on the handle as an example. In a real-life scenario, a signal transmitting base station is provided. The signal transmitting base station defines the X, Y, and Z axes of the real space, and establishes a spatial coordinate system (corresponding to the first coordinate system described above). The positioning device determines the coordinates in the spatial coordinate system by receiving a positioning signal transmitted by the base station. In this example, the first coordinate system and the second coordinate system in the virtual scene are identical as an example. In the virtual scene, the target object (user) corresponds to a human character, the positioning device mounted on the head display corresponds to the position of the human head, and the positioning device mounted on the handle corresponds to the position of the human hand.

In this example, when a scene in which a turn is desired occurs, the user can press the trigger device, which can be a button on the handle or a button on the head display or the like.

In this example, the scheme in which the present application is executed by the head is taken as an example for explanation. After the trigger device is pressed, a steering trigger command is generated for the head display.

The position conversion is started after the head display receives the steering trigger command. As shown in Fig. 2, the original position of the head display is T ₀ , and the original positions of the two handles are A ₀ and B ₀ , wherein T ₀ is set as the replacement origin of the new coordinate system, and when the steering angle is 180 degrees, the user is After the corresponding character (human) in the virtual scene is turned, in the virtual scene, the human head position becomes T ₀ ', and the positions of the two hands become A ₀ ' and B ₀ ', respectively.

As shown in Fig. 2, the coordinates of T ₀ are (X ₀ , Y ₀ , Z ₀ ), the coordinates of A ₀ are (X _A0 , Y _A0 , Z _A0 ), and the coordinates of B ₀ are (X _B0 , Y _B0 , Z _B0 ). The A ₀ 'point coordinates are (X _A0 ', Y _A0 ', Z _A0 '), and the B ₀ 'point coordinates are (X _B0 ', Y _B0 ', Z _B0 ').

When the steering angle is 180 degrees, it is calculated that:

X _A0 '=2X ₀ -X _A0 , Y _A0 '=Y _A0 ,Z _A0 '=2Z ₀ -Z _A0 ;

X _B0 '=2X ₀ -X _B0 , Y _B0 '=Y _B0 ,Z _B0 '=2Z ₀ -Z _B0 ;

T ₀ '=(X ₀ , Y ₀ , Z ₀ ).

At the same time, the user's posture corresponding to the character (human) in the virtual scene also rotates 180 degrees.

The scene information faced by the corresponding character (human) in the virtual scene is further adjusted according to the coordinates and posture of the head display and the two handles in the virtual scene when the user performs the position conversion.

In this example, after the user's corresponding character is turned in the virtual scene, the user moves in the real scene, corresponding to the movement of the user's corresponding character (human) in the virtual scene, such as the head display and the handle in the real scene from FIG. 2 The positions T ₀ , A ₀ and B _{0 are} moved to the positions T ₁ , A ₁ and B ₁ as shown in FIG. 3 , and the coordinates of the two handles in the real scene are A ₁ (X _A1 , Y _A1 , Z, respectively). _A1 ), B ₁ (X _B1 , Y _B1 , Z _B1 ), the coordinates of the head display are T ₁ (X _T1 , Y _T1 , Z _T1 ). Corresponding to the coordinates of the corresponding character hand in the virtual scene are A ₁ '(X _A1 ', Y _A1 ', Z _A1 '), B ₁ '(X _B1 ', Y _B1 ', Z _B1 '), the head The coordinates are T ₁ '(X _T1 ', Y _T1 ', Z _T1 ').

When the steering angle is 180 degrees, it is calculated that:

X _A1 '=2X ₀ -X _A1 , Y _A1 '=Y _A1 , Z _A1 '=2Z ₀ -Z _A1 ;

X _B1 '=2X ₀ -X _B1 , Y _B1 '=Y _B1 , Z _B1 '=2Z ₀ -Z _B1 ;

X _T1 '=2X ₀ -X _T1 , Y _T1 '=Y _T1 , Z _T1 '=2Z ₀ -Z _T1 .

According to the calculated coordinates of the head and the two handles in the virtual scene when the user is in the real-time position, the scene information faced by the corresponding character (human) in the virtual scene is further adjusted.

In summary, in this embodiment, the user-oriented role steering is implemented in the virtual scenario, and the user does not need to be redirected in the real-life scenario, thereby avoiding the problem that the user cannot be located due to the user's steering in the real-life scenario, thereby improving the user experience.
