Referring to fig. 1b, fig. 1b is a schematic flow chart illustrating a method for adjusting a viewing angle according to an embodiment of the present disclosure. The visual angle adjusting method comprises the following steps:

in step 101, the graphical user interface provides a first view angle control area and a second view angle control area, and the second view angle control area includes a view angle height control.

The graphical user interface is displayed as a virtual environment in a game scene, and the virtual environment is provided when an application program runs on a terminal, and can be a simulation environment of a real world, a semi-simulation semi-fictional environment or a pure fictional environment. The target object is a camera model, for example, in the case of an FPS game, the camera model is located on the head or neck of the virtual character when viewed from a first person, and the camera model is located behind the virtual character when viewed from a third person. Part of the game scene is a picture generated by observing the virtual environment by the camera model in a certain view angle direction.

The graphical user interface further includes a first viewing angle control area 11 and a second viewing angle control area 12, wherein the first viewing angle control area 11 and the second viewing angle control area 12 can implement different viewing angle adjustment functions according to a user's non-touch operation.

Specifically, the second viewing angle control area 12 includes a viewing angle height control 121, and the viewing angle height control 121 is used for adjusting the height of the viewing angle. Referring to fig. 1c and fig. 1d, fig. 1c is a first application scenario diagram of a perspective adjustment method provided in the embodiment of the present application, and fig. 1d is a schematic diagram of a world coordinate system in a virtual environment provided in the embodiment of the present application. Taking the example of a user playing a game in an observer view (OB), the virtual environment has a world coordinate system constructed by an X-axis, a Y-axis, and a Z-axis, and therefore the camera model located in the virtual environment also has its corresponding coordinates (X)₁,Y₁,Z₁)。

In step 102, in response to the touch operation applied to the first view angle control area, a projection position of the view angle on a designated plane is adjusted.

The projection position of the viewing angle on the designated plane, that is, the projection position of the camera model on the designated plane, is here the plane 20 constructed by the X axis and the Y axis in the virtual environment. That is, the first viewing angle control area 11 is used to control the front-back and left-right movement of the camera model in the virtual scene.

Referring to fig. 1c and fig. 1d, fig. 1c is a first application scenario diagram of a perspective adjustment method provided in the embodiment of the present application, and fig. 1d is a schematic diagram of a world coordinate system in a virtual environment provided in the embodiment of the present application. Taking the example of a user playing a game in an observer view (OB), the virtual environment has a world coordinate system constructed by an X-axis, a Y-axis, and a Z-axis, and therefore the camera model located in the virtual environment also has its corresponding coordinates (X)₁,Y₁,Z₁). The designated plane here is a plane constructed by the X axis and the Y axis.

Specifically, a wheel control 111 is arranged in the first visual angle control area 11, and a user controls the rocker in the wheel control 111 to move forward, backward, leftward and rightward so as to control the visual angle to move forward, backward, leftward and rightward.

the step of adjusting the projection position of the viewing angle on the designated plane in response to the touch operation applied to the first viewing angle control area includes:

and adjusting the target object to move on the designated plane in the horizontal direction in response to the touch operation acting on the first visual angle control area.

The target object is a camera model, and the projection position of the control view angle on the designated plane, that is, the target object is controlled to move in the horizontal direction (front, back, left and right) on the designated plane.

In step 103, in response to a first operation on the viewing angle height control, the height of the viewing angle perpendicular to the designated plane is adjusted.

The first operation is a pressing operation on the viewing angle height control 121, the viewing angle height control 121 adjusts the position of the camera model on the Z axis according to the pressing duration of the pressing operation, and since the Y axis is divided into a positive half axis and a negative half axis, the corresponding height control 121 may further include a first sub-viewing angle height control 1211 adjusted to the positive half axis of the Z axis and a second sub-viewing angle height control 1212 adjusted to the negative half axis of the Z axis. The height perpendicular to the designated plane is the distance of the camera model from the plane 20 constructed by the X-axis and Y-axis.

In some embodiments, the step of adjusting the height of the perspective perpendicular to the specified plane in response to the first operation on the perspective height control comprises:

and adjusting the height of the target object perpendicular to the specified plane in response to a first operation acting on the visual angle height control.

And adjusting the height of the visual angle perpendicular to the specified plane, namely controlling the target object to move along the positive semi-axis direction or the negative semi-axis direction of the Z axis on the specified plane.

And 104, responding to a second operation which starts from the visual angle height control and acts on the specified area, and adjusting the orientation of the visual angle.

Referring to fig. 1e, fig. 1e is a schematic view of a second application scenario of the method for adjusting a viewing angle according to the embodiment of the present application, where a designated area 13 is used to receive a second operation of a user and adjust a viewing angle orientation according to the second operation. Taking the first operation as a pressing operation as an example, when the user presses the viewing angle height control 121, the function of adjusting the height of the viewing angle height control 121 is implemented, the designated area 13 is displayed on the graphical user interface, and in order to facilitate the user to operate the viewing angle height control 121 and the designated area 13 by using a single finger, the designated area 13 may be set to be the outer side of the viewing angle height control 121, that is, the inner periphery of the designated area 13 is adjacent to the outer periphery of the second viewing angle control area 121. The second response area 12 may be other areas of the graphical user interface except for the first viewing angle control area 11 and the second viewing angle control area 12, and the outer periphery of a specific designated area may be a circle or a polygon, which is not limited herein.

In some embodiments, the graphical user interface provides a first perspective control area and a second perspective control area, the second perspective control area including a perspective height control, comprising:

in some embodiments, please refer to fig. 1f, where fig. 1f is a schematic rotation diagram of a rotation angle of a camera model according to an embodiment of the present disclosure. The view angle direction of the lens 30 in the camera model can be adjusted by rotating the U-axis and the R-axis. Based on second operations of different operation modes, the second operations can be divided into two types, the first type is that a user slides a finger pressing the visual angle height control element 121 to the designated area 13, namely the second operation is continuous with the first operation, so that the transition from the adjustment of the visual angle height to the adjustment of the visual angle rotation is smoother, and the operations are more coherent; the second is that the user lifts the finger that pressed the viewing angle height control 121 and presses the designated area 13 for a designated period of time. Therefore, the way of rotating the view angle of the camera model is different for different operation modes, and the following description is divided into two modes.

Referring to fig. 1g, regarding that the second operation is a sliding operation of sliding from the height control to the designated area, fig. 1g is a third application scenario diagram of the viewing angle adjusting method according to the embodiment of the present application. In some embodiments, the step of adjusting the orientation of the viewing angle in response to the second operation that starts at the viewing angle height control and acts on the designated area comprises:

(1) acquiring a touch position of a second operation in the designated area and a reference point position in the graphical user interface;

(2) determining a current sliding direction of a second operation based on the touch position and the reference point position;

(3) and determining the target orientation of the visual angle according to the current sliding direction, and adjusting the orientation of the visual angle according to the target orientation.

The rotation mode of the camera model can be divided into rotation around the U axis only, and rotation around the U axis and the R axis, based on the working mode of rotation around the U axis only, the touch position of the sliding operation corresponding to the terminal device can be obtained in real time, and the sliding direction (namely the current sliding direction) of the sliding operation of the user is determined according to the touch position and the reference point position on the graphical user interface.

For example: the touch coordinates are (X2, Y2), the reference point is the coordinates (X3, Y3) of the center point of the viewing angle height control 121, and then the sine value of the angle can be determined according to | (Y2-Y3) |/| (X2-X3) |, the angle is determined according to the sine value, and then the current sliding direction is determined. And determining the orientation corresponding to the current sliding direction as the target orientation of the visual angle, and controlling the camera module to rotate around the U axis until the lens orientation of the camera module is overlapped with the target orientation.

In some embodiments, a mapping relationship between the current sliding direction and the viewing angle orientation may be set, so that after the current sliding direction is determined, the corresponding viewing angle orientation is determined as the target orientation according to the mapping relationship.

For example, the touch coordinates are (X2, Y2), the coordinates of the center point of the viewing angle height control 121 are (X3, Y3), a sine value of an angle can be determined according to | (Y2-Y3) |/| (X2-X3) |, the angle is determined according to the sine value, the current sliding direction is determined, a mapping relation between the viewing angle direction and each sliding direction can be established in advance, and the target direction of the viewing angle is determined according to the mapping relation after the current sliding direction is determined.

In some embodiments, as shown in fig. 1h, fig. 1h is a schematic view of a fourth application scenario of the method for adjusting a viewing angle provided in this embodiment of the present application. When the sliding operation from the viewing angle height control 121 to the designated area 13 is detected, the display position of the viewing angle height control 121 on the graphical user interface is adjusted according to the touch position of the second operation.

The position of the center point of the controllable viewing angle height control element 121 moves along with the second operation, so that the viewing angle height control element 121 moves along with the second operation, and a user can visually feel the sliding operation.

In some embodiments, the step of determining the current sliding direction of the second operation based on the touch position and the position of the reference point includes:

(1) determining a current sliding direction and a current sliding distance of a second operation based on the touch position and the position of the reference point;

(2) the step of determining the target orientation of the view angle according to the current sliding direction and adjusting the orientation of the view angle according to the target orientation comprises:

(3) and determining the target orientation of the visual angle according to the current sliding direction and the current sliding distance, and adjusting the orientation of the visual angle according to the target orientation.

The camera module which can rotate around the U axis and the R axis in the working mode can acquire the touch position of the sliding operation on the terminal equipment in real time, determine the sliding direction (current sliding direction) and the sliding distance (current sliding distance) of the sliding operation of the user according to the touch position and the reference point position on the graphical user interface, and adjust the visual angle direction of the camera model in real time based on the current sliding direction and the current sliding distance. Specifically, the touch position is a touch coordinate of the user touching the screen, and the reference point position may be a center point coordinate of the viewing angle height control 121.

Specifically, in order to enable the user to achieve an accurate adjustment effect according to the viewing requirement, the distance between the touch coordinate and the central point coordinate can be calculated according to and according to the pythagorean theorem after the current sliding direction is determined, namely the current sliding distance. And determining the visual angle rotation angle of the visual angle in the visual angle direction corresponding to the current sliding direction according to the current sliding distance. And determines the orientation of the angle of view rotation in the direction of view rotation as the target orientation.

In some embodiments, the step of determining the target orientation of the view according to the current sliding direction and the current sliding distance includes:

(1.1) determining the current sliding direction as a viewing angle rotating direction;

(1.2) acquiring a maximum angle by which the viewing angle is rotatable in the viewing angle rotating direction, and a maximum distance by which the second operation is slidable in the current sliding direction;

(1.3) determining a view angle rotation angle based on the current sliding distance, the maximum distance, and the maximum angle;

and (1.4) determining the target orientation of the visual angle according to the visual angle rotating direction and the visual angle rotating angle.

After the current sliding direction is determined, the lens of the camera model can be controlled to rotate in the current sliding direction, and the specific rotating mode can rotate around the U shaft, so that the lens of the camera model can rotate.

The angle of the lens of the camera model raised in the view angle rotation direction can be determined by acquiring the maximum angle rotatable in the view angle rotation direction, for example, 90 °, and the maximum distance slidable in the current sliding direction, for example, 6cm, of the second operation, and determining the target orientation based on the sliding distance, the maximum distance, and the maximum angle.

When the visual angle rotating angle is determined, the lens of the camera model can be controlled to rotate according to the visual angle rotating angle, and the specific rotating mode can rotate around the R axis so that the lens of the camera model can be lifted.

In some embodiments, the step of determining the target orientation of the viewing angle according to the viewing angle rotation direction and the viewing angle rotation angle comprises:

(1.1) determining a distance ratio of the current sliding distance to the maximum distance;

and (1.2) determining a view angle rotation angle according to the distance ratio and the maximum angle, and determining the orientation of the target according to the current sliding direction and the view angle rotation angle.

Wherein if the maximum angle rotatable in the viewing angle rotation direction is 90 °, and the maximum distance by which the second operation can slide in the current sliding direction is 6cm, and the current sliding distance is 2cm, the distance ratio of the current sliding distance to the maximum distance is 1/3, and the maximum angle is 90 °, the viewing angle rotation angle is 90 ° × 1/3 ═ 30 °. Therefore, the target orientation is the orientation with the angle as the viewing angle rotation angle in the viewing angle rotation direction corresponding to the current sliding direction.

In some embodiments, the method further comprises:

(1.1) if the sliding operation of moving from the specified area to the visual angle height control is detected, acquiring the stay time of the sliding operation in the visual angle height control;

(1.2) comparing the stay time with a preset time to obtain a comparison result;

(1.3) if the comparison result shows that the staying time is longer than the preset time, adjusting the height of the visual angle vertical to the specified plane;

(1.4) if the comparison result shows that the stay time is less than the preset time, judging whether the second operation is detected;

(1.5) if the second operation is detected, returning to the step of acquiring the touch position of the second operation in the designated area and the reference point position in the graphical user interface until the second operation cannot be detected.

In order to avoid that the lens lifting angle is adjusted to be too high, so that the user passes through the first control when performing the sliding operation in the opposite direction, and the lens lifting angle is not adjusted but the camera model is moved, therefore, a preset time duration may be set, and how to adjust the viewing angle of the target object is further determined by comparing the size relationship between the stay time duration of the second operation in the viewing angle height control 121 and the preset time duration.

Specifically, if the dwell time is longer than the preset time, it may be determined that the user currently wants to adjust the vertical height of the camera model on the designated plane, and if the dwell time is shorter than the preset time, it may not be determined which adjustment mode the user currently wants to perform, so as to determine whether to detect the second operation of moving from the viewing angle height control 121 to the designated area 13; if the second operation is detected, returning to the step of acquiring the touch position of the sliding operation in the designated area and the reference point position in the graphical user interface until the second operation cannot be detected.

In some embodiments, the method further comprises:

if the second operation cannot be detected after the sliding operation is moved from the designated area 13 to the viewing angle height control 121, the designated area 13 is not displayed.

If the second operation cannot be detected, that is, it is determined that the user has lifted the finger, and the screen of the terminal device is no longer touched, the state of each control in fig. 1c is restored, that is, the designated area 13 is not displayed.

In some embodiments, in response to a second operation on the response area, the step of adjusting the viewing direction of the target object according to the second operation includes:

(1.1) acquiring the pressing position, the pressing duration and the reference point position in the graphical user interface of the pressing operation in the designated area;

(1.2) determining a viewing angle rotation direction based on the pressing position and the reference point position;

(1.3) determining a visual angle rotation angle corresponding to the pressing duration according to a preset mapping relation;

The difference between the pressing operation and the sliding operation for determining the rotation direction of the target view angle is as follows: the visual angle rotation angle is determined by the pressing time length in the pressing operation. By determining the mapping relation between the pressing duration and the visual angle rotation angle in advance, the corresponding visual angle rotation angle can be determined when the pressing duration of the user is obtained. For example: the pressing time period is 1s, the viewing angle is rotated by 30 °, the pressing time period is 2s, and the viewing angle is rotated by 60 °.

As can be seen from the above, in the embodiment of the present application, a first viewing angle control area and a second viewing angle control area are provided through a graphical user interface, where the second viewing angle control area includes a viewing angle height control; responding to touch operation acting on the first visual angle control area, and adjusting the projection position of the visual angle on a designated plane; adjusting the height of the visual angle perpendicular to the designated plane in response to a first operation on the visual angle height control; and responding to a second operation which starts from the visual angle height control and acts on the designated area, and adjusting the orientation of the visual angle. Therefore, different operations are performed on the visual angle height control piece, multiple different visual angle adjusting functions (adjusting the visual angle height and the visual angle orientation) are achieved, complexity of visual angle adjusting operations is reduced, and visual angle adjusting efficiency is improved.

The method described in connection with the above embodiments will be described in further detail below by way of example.

Referring to fig. 2, fig. 2 is another schematic flow chart of a method for adjusting a viewing angle according to an embodiment of the present application, in which the second operation is an example of a sliding operation, and a specific flow of the method may be as follows:

in step 201, the graphical user interface provides a first view angle control area and a second view angle control area, and the second view angle control area includes a view angle height control.

Specifically, the second viewing angle control area 12 includes a viewing angle height control 121, and the viewing angle height control 121 is used for adjusting the height of the viewing angle. Referring to fig. 1c and fig. 1d, fig. 1c is a first application scenario diagram of a perspective adjustment method provided in the embodiment of the present application, and fig. 1d is a schematic diagram of a world coordinate system in a virtual environment provided in the embodiment of the present application. Taking the example of a user playing a game in the observer view (OB), the virtual environment has a world coordinate system constructed by an X-axis, a Y-axis and a Z-axis,the camera model located in the virtual environment therefore also has its corresponding coordinates (X)₁,Y₁,Z₁)。

In step 202, in response to the touch operation applied to the first view angle control area, the adjustment target object is moved in the horizontal direction on the designated plane.

Specifically, a wheel control 111 is arranged in the first visual angle control area 11, and a user controls the rocker in the wheel control 111 to move forward, backward, leftward and rightward so as to control the visual angle to move forward, backward, leftward and rightward. The target object is a camera model, and the projection position of the control view angle on the designated plane, namely the control target object, moves in the horizontal direction (front, back, left and right) on the designated plane.

In step 203, the height of the target object perpendicular to the specified plane is adjusted in response to the first operation acting on the viewing angle height control.

Specifically, the target object is a camera model, and the height of the view angle perpendicular to the designated plane is adjusted, that is, the target object is controlled to move on the designated plane in the positive semi-axis direction or the negative semi-axis direction of the Z-axis.

In step 204, the touch position of the second operation in the designated area and the reference point position in the graphical user interface are obtained.

In step 205, a current sliding direction and a current sliding distance of the second operation are determined based on the touch position and the position of the reference point.

In order to enable a user to achieve an accurate adjustment effect according to a watching requirement, after the current sliding direction is determined, the distance between the touch coordinate and the coordinate of the central point is calculated according to the Pythagorean theorem, namely the current sliding distance. And determining the visual angle rotation angle of the visual angle in the visual angle direction corresponding to the current sliding direction according to the current sliding distance. And determines the orientation of the angle of view rotation in the direction of view rotation as the target orientation.

In step 206, the current sliding direction is determined as the viewing angle rotating direction.

The angle of the lens of the camera model raised in the view angle rotation direction can be determined by acquiring the maximum angle rotatable in the view angle rotation direction, for example, 90 °, and the maximum distance slidable in the current sliding direction, for example, 6cm, of the second operation, and determining the target orientation based on the sliding distance, the maximum distance, and the maximum angle. When the visual angle rotating angle is determined, the lens of the camera model can be controlled to rotate according to the visual angle rotating angle, and the specific rotating mode can rotate around the R axis so that the lens of the camera model can be lifted.

In step 207, the maximum angle by which the viewing angle is rotatable in the viewing angle rotating direction and the maximum distance by which the second operation is slidable in the current sliding direction are acquired.

For example, if the maximum angle rotatable in the viewing angle rotation direction is 90 °, and the maximum distance by which the sliding operation can slide in the current sliding direction is 6cm, and the current sliding distance is 2cm, the distance ratio of the current sliding distance to the maximum distance is 1/3.

In step 208, a viewing angle rotation angle is determined based on the current sliding distance, the maximum distance, and the maximum angle.

For example, if the maximum angle is 90 ° and the distance ratio is 1/3, the viewing angle rotation angle is 30 ° as 90 ° × 1/3.

In step 209, the target orientation of the viewing angle is determined according to the viewing angle rotation direction and the viewing angle rotation angle.

Wherein, after determining visual angle turned angle, the accessible control camera model's camera lens rotates according to visual angle turned angle, and specific rotation mode accessible is rotatory around the R axle to make camera model's camera lens lift.

In step 210, if a sliding operation moving from the designated area to the viewing angle height control is detected, a staying time of the sliding operation in the viewing angle height control is obtained.

In order to avoid that the lens lifting angle is adjusted to be too high, so that the user passes through the first control when performing the sliding operation in the opposite direction, and the lens lifting angle is not adjusted but the camera model is moved, therefore, a preset time duration may be set, and how to adjust the viewing angle of the target object is further determined by comparing the size relationship between the stay time duration of the second operation in the viewing angle height control 121 and the preset time duration. Therefore, in this step, the stay time period of the sliding operation within the first response region is acquired, for example, 4 s.

In step 211, the staying time is compared with a preset time to obtain a comparison result.

For example, if the preset time is 5s and the stay time is 4s, the comparison result indicates that the stay time is less than the preset time; if the staying time is 6s, the comparison result shows that the staying time is longer than the preset time.

In step 212, if the comparison result indicates that the staying time is longer than the predetermined time, the height of the viewing angle perpendicular to the designated plane is adjusted.

If the staying time length is longer than the preset time length, the vertical height of the camera model on the specified plane, which is currently to be adjusted by the user, can be judged.

In step 213, if the comparison result indicates that the staying time is less than the predetermined time, it is determined whether the second operation is detected.

If the staying time length is less than the preset time length, the current adjustment mode to be performed by the user cannot be judged, and therefore whether the sliding operation of moving from the first response area to the second response area is detected or not is judged.

In step 214, if the second operation is detected, the step of obtaining the touch position of the second operation in the designated area and the reference point position in the graphical user interface is returned to until the second operation cannot be detected. .

If the second operation is detected, returning to the step of acquiring the touch position of the second operation in the designated area and the reference point position in the graphical user interface until the second operation cannot be detected.
