In this embodiment, description will be made from the viewpoint of a viewing angle adjusting apparatus which can be integrated in a computer device having a storage unit and a microprocessor mounted thereon and having arithmetic capability.
Referring to fig. 1b, fig. 1b is a 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 viewing angle control region and a second viewing angle control region, wherein the second viewing angle control region comprises a viewing angle height control.
The graphical user interface displays a virtual environment in a game scene, wherein the virtual environment is a virtual environment provided when an application program runs on a terminal, and can be a simulation environment for a real world, a semi-simulation and semi-fictitious environment or a pure fictitious environment. The target object is a camera model, for example, an FPS game, which is positioned at the head or neck of the virtual character when at a first person viewing angle and behind the virtual character when at a third person viewing angle. The partial game scene is a picture generated by observing the virtual environment through 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 the user's non-touch operation.
Specifically, the second viewing angle control area 12 includes a viewing angle height control 121, and the name implies that the viewing angle height control 121 is used to adjust the height of the viewing angle. Referring to fig. 1c and fig. 1d, fig. 1c is a schematic diagram of a first application scenario of the viewing angle 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 using an observer viewing angle (OB) to play a game, the virtual environment has a world coordinate system constructed with an X-axis, a Y-axis, and a Z-axis, and thus the camera model located in the virtual environment also has its corresponding coordinates (X 1 ,Y 1 ,Z 1 ）。
In step 102, the projection position of the viewing angle on the designated plane is adjusted in response to the touch operation applied to the first viewing angle control region.
Wherein the projection position of the view angle on the specified plane, i.e. the projection position of the camera model on the specified plane, the specified plane here is the plane 20 constructed by the X-axis and the Y-axis in the virtual environment. I.e. the first view control area 11 is used to control the movement of the camera model back and forth, left and right in the virtual scene.
Referring to fig. 1c and fig. 1d, fig. 1c is a schematic diagram of a first application scenario of the viewing angle 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 using an observer viewing angle (OB) to play a game, the virtual environment has a world coordinate system constructed with an X-axis, a Y-axis, and a Z-axis, and thus the camera model located in the virtual environment also has its corresponding coordinates (X 1 ,Y 1 ,Z 1 ). The designated plane here is a plane constructed by the X-axis and the Y-axis.
Specifically, the wheel disc control 111 is disposed in the first view angle control area 11, and the user controls the rocker in the wheel disc control 111 to move forwards, backwards, leftwards and rightwards so as to control the view angle to move forwards, backwards, leftwards and rightwards.
In some embodiments, the content displayed by the user graphical interface is an environment picture when the target object observes the virtual environment in a preset viewing angle direction;
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 region includes:
and adjusting the target object to move horizontally on the designated plane in response to the touch operation acted 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, namely, the movement of the target object in the horizontal direction (front, back, left and right) on the designated plane is controlled.
In step 103, the height of the viewing angle perpendicular to the designated plane is adjusted in response to a first operation on the viewing angle height control.
The first operation is a pressing operation on the view angle height control 121, where the view angle height control 121 adjusts a position of the camera model on the Z axis according to a 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 view angle height control 121 may further include a first sub-view angle height control 1211 adjusted to the positive half axis of the Z axis and a second sub-view angle height control 1212 adjusted to the negative half axis of the Z axis. The height perpendicular to the specified plane is the distance of the camera model from the plane 20 constructed by the X-axis and the Y-axis.
In some embodiments, the step of adjusting the height of the viewing angle perpendicular to the designated plane in response to a first operation of the viewing angle height control comprises:
in response to a first operation acting on the perspective height control, a height of the target object perpendicular to the designated plane is adjusted.
The target object is a camera model, and the height of the visual angle perpendicular to the appointed plane is adjusted, namely the target object is controlled to move along the positive half axis direction or the negative half axis direction of the Z axis on the appointed plane.
Step 104, responding to a second operation starting from the visual angle height control and acting on the designated area, and adjusting the orientation of the visual angle.
Referring to fig. 1e, fig. 1e is a schematic diagram of a second application scenario of the viewing angle adjustment method provided in the embodiment of the present application, where the designated area 13 is configured to receive a second operation of a user, and adjust a viewing angle direction 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 achieved, 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 one finger, the designated area 13 may be set as 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 12. The specific area 13 may be other areas of the gui except the first viewing angle control area 11 and the second viewing angle control area 12, and the periphery of the specific area may be circular or polygonal, which is not limited herein.
In some embodiments, the graphical user interface provides a first viewing angle control region and a second viewing angle control region, the second viewing angle control region comprising a viewing angle height control, comprising:
in some embodiments, referring to fig. 1f, fig. 1f is a rotation schematic diagram of a rotation angle of a camera model according to an embodiment of the present application. The viewing angle direction of the lens 30 in the camera model can be adjusted by rotating the U-axis and the R-axis. Based on the second operation of different operation modes, the second operation can be divided into two types, wherein the first type is that a user slides a finger pressing the visual angle height control 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 operation is more continuous; the second is that the user lifts the finger pressing the view height control 121 and presses the designated area 13 for a designated period of time. Therefore, the mode of rotating the view angle of the camera model is different for different operation modes, and the following two modes are described.
For the second operation, which is a sliding operation performed by sliding the height control to the designated area, please refer to fig. 1g, fig. 1g is a schematic diagram of a third application scenario of the viewing angle adjustment 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 a second operation initiated by the viewing angle height control and acting on the designated area includes:
(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 the 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 only, 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 (i.e. the current sliding direction) of the sliding operation of the user can be determined according to the touch position and the reference point position on the graphical user interface.
For example: the touch coordinates are (X2, Y2), and the reference point position is the center point coordinates (X3, Y3) of the view angle height control 121, so that the sine value of the angle can be determined according to the | (Y2-Y3) |/| (X2-X3) |, the angle can be determined according to the sine value, and the current sliding direction can be further determined.

In some embodiments, as shown in fig. 1h, fig. 1h is a schematic diagram of a fourth application scenario of the viewing angle adjustment method provided in the embodiments of the present application. When a sliding operation from the view angle height control 121 to the designated area 13 is detected, the display position of the view angle height control 121 on the graphical user interface is adjusted according to the touch position of the second operation.
The center point position of the controllable viewing angle height control 121 moves along with the second operation, so that the viewing angle height control 121 moves along with the second operation, and the user intuitively experiences 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 of the second operation and a current sliding distance of the second operation based on the touch position and the position of the reference point;

(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 is rotatable around a U axis and an R axis for a working mode, a touch position of a sliding operation corresponding to a terminal device can be obtained in real time, a sliding direction (i.e., a current sliding direction) of the sliding operation of a user and a sliding distance (a current sliding distance) are determined according to the touch position and a reference point position on a graphical user interface, and a viewing angle direction of the camera module is adjusted in real time based on the current sliding direction and the current sliding distance. Specifically, the touch position is a touch coordinate of a user touch on the screen, and the reference point position may be a center point coordinate of the view angle height control 121.
Specifically, in order to enable the user to achieve the effect of accurate adjustment according to the watching requirement, after the current sliding direction is determined, the distance between the touch control coordinate and the center point coordinate is calculated according to the Pythagorean theorem, namely the current sliding distance. And then determining the view angle rotation angle of the view angle in the view angle direction corresponding to the current sliding direction according to the current sliding distance. And the orientation of the viewing angle rotation angle in the viewing angle rotation direction is determined as the target orientation.
In some embodiments, the step of determining the target orientation of the viewing angle according to the current sliding direction and the current sliding distance includes:
(1.1) determining the current sliding direction as a viewing angle rotation direction;
(1.2) acquiring a maximum angle at which the viewing angle is rotatable in the viewing angle rotation direction, and a maximum distance at which the second operation is slidable in the current sliding direction;
(1.3) determining a viewing angle rotation angle based on the current sliding distance, the maximum distance, and the maximum angle;
(1.4) determining a target orientation of the viewing angle based on the viewing angle rotation direction and the viewing angle rotation angle.
After the current sliding direction is determined, the lens of the camera model can be controlled to rotate towards the current sliding direction, and the specific rotation mode can rotate around the U axis so that the lens of the camera model can rotate.
The angle of elevation of the lens of the camera model in the direction of view rotation can be determined by the current sliding distance in such a way that a maximum angle rotatable in the direction of view rotation is obtained, for example 90 °, and a maximum distance slidable in the current sliding direction by the second operation, for example 6cm, and the target orientation is determined based on the sliding distance, the maximum distance and the maximum angle.
When the rotation angle of the visual angle is determined, the lens of the camera model can be controlled to rotate according to the rotation angle of the visual angle, and the specific rotation mode can rotate around the R axis so as to enable the lens of the camera model to 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 includes:
(1.1) determining a distance ratio of the current sliding distance to the maximum distance;
and (1.2) determining a visual angle rotation angle according to the distance ratio and the maximum angle, and determining a target orientation according to the current sliding direction and the visual angle rotation angle.
Wherein if the maximum angle rotatable in the viewing angle rotation direction is 90 °, and the maximum distance slidable in the current sliding direction by the second operation is 6cm, and the current sliding distance is 2cm, the distance ratio of the current sliding distance to the maximum distance is 1/3, the maximum angle is 90 °, and the viewing angle rotation angle is 90 ° x 1/3=30°. The target orientation is thus the orientation in which the angle in the viewing angle rotation direction corresponding to the current sliding direction is the viewing angle rotation angle.
In some embodiments, the method further comprises:
(1.1) if the sliding operation moving from the designated 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 residence time with a preset time to obtain a comparison result;
(1.3) if the comparison result shows that the stay time length is longer than the preset time length, adjusting the height of the visual angle vertical to the appointed plane;
(1.4) if the comparison result shows that the residence time is less than the preset time, judging whether the second operation is detected;
and (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 too high, the user passes through the first control when performing the sliding operation in the opposite direction, so that the lens lifting angle is not adjusted but the camera model is moved, a preset duration may be set, and how to adjust the view angle of the target object may be further determined by comparing the size relationship between the residence duration of the second operation in the view angle height control 121 and the preset duration.
Specifically, if the stay time length is longer than the preset time length, it may be determined that the user is currently about to adjust the vertical height of the camera model on the designated plane, and if the stay time length is shorter than the preset time length, it may not be determined what adjustment mode the user is currently about to perform, so as to determine whether the second operation of moving from the view angle height control 121 to the designated area 13 is detected; and 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 moves from the designated area 13 to the view angle height control 121, the designated area 13 is not displayed.
If the second operation cannot be detected, it is determined that the user lifts the finger, and the screen of the terminal device is not touched any more, so that the state of each control in fig. 1c is restored, that is, the designated area 13 is not displayed.
For the manner in which the user lifts the finger pressing the view height control of the first control and presses the designated area for the designated period of time, in some embodiments, the step of adjusting the view direction of the target object according to the second operation in response to the second operation for the response area includes:
(1.1) acquiring a pressing position, a pressing duration of the pressing operation in the designated area, and a reference point position in the graphical user interface;
(1.2) determining a viewing angle rotation direction based on the pressing position and the reference point;
(1.3) determining the visual angle rotation angle corresponding to the pressing duration according to a preset mapping relation;
(1.4) determining a target orientation of the viewing angle based on the viewing angle rotation direction and the viewing angle rotation angle.
The difference between the pressing operation and the sliding operation for determining the rotation direction of the target viewing angle is that: the angle of view rotation is determined in the pressing operation by the pressing time period. The mapping relation between the pressing time length and the visual angle rotation angle is determined in advance, so that when the pressing time length of a user is obtained, the corresponding visual angle rotation angle can be determined. For example: the viewing angle is rotated 30 ° when the pressing time period is 1s, and is rotated 60 ° when the pressing time period is 2 s.
As can be seen from the above, the embodiment of the present application provides a first viewing angle control area and a second viewing angle control area through the gui, where the second viewing angle control area includes a viewing angle height control; responding to the touch operation acted on the first visual angle control area, and adjusting the projection position of the visual angle on the appointed plane; adjusting a height of the viewing angle perpendicular to the designated plane in response to a first operation acting on the viewing angle height control; the orientation of the viewing angle is adjusted in response to a second operation initiated at the viewing angle height control and acting on the designated area. Therefore, by carrying out different operations on the visual angle height control, various different visual angle adjusting functions (adjusting the visual angle height and the visual angle direction) are realized, the complexity of visual angle adjusting operation is reduced, and the visual angle adjusting efficiency is improved.
The methods described in connection with the above embodiments are described in further detail below by way of example.
Referring to fig. 2, fig. 2 is another flow chart of the method for adjusting a viewing angle according to the embodiment of the present application, and the present embodiment is an example of using the second operation as a sliding operation, and the specific flow chart of the method may be as follows:
in step 201, the graphical user interface provides a first viewing angle control area and a second viewing angle control area, wherein the second viewing angle control area comprises a viewing angle height control.
The graphical user interface displays a virtual environment in a game scene, wherein the virtual environment is a virtual environment provided when an application program runs on a terminal, and can be a simulation environment for a real world, a semi-simulation and semi-fictitious environment or a pure fictitious environment. The target object is a camera model, for example, an FPS game, which is positioned at the head or neck of the virtual character when at a first person viewing angle and behind the virtual character when at a third person viewing angle. The partial game scene is a picture generated by observing the virtual environment through the camera model in a certain view angle direction.
Specifically, the second viewing angle control area 12 includes a viewing angle height control 121, and the name implies that the viewing angle height control 121 is used to adjust the height of the viewing angle. Referring to fig. 1c and fig. 1d, fig. 1c is a schematic diagram of a first application scenario of the viewing angle 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 using an observer viewing angle (OB) to play a game, the virtual environment has a world coordinate system constructed with an X-axis, a Y-axis, and a Z-axis, and thus the camera model located in the virtual environment also has its corresponding coordinates (X 1 ,Y 1 ,Z 1 ）。
In step 202, the target object is adjusted to move in the horizontal direction on the designated plane in response to the touch operation applied to the first viewing angle control region.
Wherein the projection position of the view angle on the specified plane, i.e. the projection position of the camera model on the specified plane, the specified plane here is the plane 20 constructed by the X-axis and the Y-axis in the virtual environment. I.e. the first view control area 11 is used to control the movement of the camera model back and forth, left and right in the virtual scene.
Referring to fig. 1c and 1d, fig. 1c is a schematic view of an embodiment of the present application Fig. 1d is a schematic diagram of a world coordinate system in a virtual environment according to an embodiment of the present application. Taking the example of a user using an observer viewing angle (OB) to play a game, the virtual environment has a world coordinate system constructed with an X-axis, a Y-axis, and a Z-axis, and thus the camera model located in the virtual environment also has its corresponding coordinates (X 1 ,Y 1 ,Z 1 ). The designated plane here is a plane constructed by the X-axis and the Y-axis.
Specifically, the wheel disc control 111 is disposed in the first view angle control area 11, and the user controls the rocker in the wheel disc control 111 to move forwards, backwards, leftwards and rightwards so as to control the view angle to move forwards, backwards, leftwards and rightwards. The target object is a camera model, and the projection position of the control view angle on the designated plane, namely the movement of the target object in the horizontal direction (front, back, left and right) on the designated plane is controlled.
In step 203, the height of the target object perpendicular to the specified plane is adjusted in response to a first operation acting on the perspective height control.
The first operation is a pressing operation on the view angle height control 121, the view 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 the corresponding height control 121 may further include a first sub-view angle height control 1211 adjusted to the positive Z axis and a second sub-view angle height control 1212 adjusted to the negative Z axis because the Y axis is divided into the positive half axis and the negative half axis. The height perpendicular to the specified plane is the distance of the camera model from the plane 20 constructed by the X-axis and the Y-axis.
Specifically, the target object is a camera model, and the height of the visual angle perpendicular to the designated plane is adjusted, namely, the target object is controlled to move along the positive half-axis direction or the negative half-axis direction of the Z axis on the designated plane.
In step 204, the touch location of the second operation within the designated area and the reference point location within the graphical user interface are obtained.
For example, the touch coordinates are (X2, Y2), the coordinates of the center point of the view angle height control 121 are (X3, Y3), the sine value of the angle can be determined according to the | (Y2-Y3) |/| (X2-X3) |, the angle can be determined according to the sine value, the current sliding direction can be further determined, and the mapping relationship between the view angle orientation and each sliding direction can be established in advance, so that after the current sliding direction is determined, the target orientation of the view angle can be determined according to the mapping relationship.
The center point position of the controllable viewing angle height control 121 moves along with the second operation, so that the viewing angle height control 121 moves along with the second operation, and the user intuitively experiences the sliding operation.
In step 205, a current sliding direction of the second operation 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 effect of accurate adjustment according to watching requirements, after determining a current sliding direction, the distance between the touch control coordinate and the center point coordinate is calculated according to the Pythagorean theorem, namely the current sliding distance. And then determining the view angle rotation angle of the view angle in the view angle direction corresponding to the current sliding direction according to the current sliding distance. And the orientation of the viewing angle rotation angle in the viewing angle rotation direction is determined as the target orientation.
In step 206, the current sliding direction is determined as the viewing angle rotation direction.
After the current sliding direction is determined, the lens of the camera model can be controlled to rotate towards the current sliding direction, and the specific rotation mode can rotate around the U axis so that the lens of the camera model can rotate.
The angle of elevation of the lens of the camera model in the direction of view rotation can be determined by the current sliding distance in such a way that a maximum angle rotatable in the direction of view rotation is obtained, for example 90 °, and a maximum distance slidable in the current sliding direction by the second operation, for example 6cm, and the target orientation is determined based on the sliding distance, the maximum distance and the maximum angle. When the rotation angle of the visual angle is determined, the lens of the camera model can be controlled to rotate according to the rotation angle of the visual angle, and the specific rotation mode can rotate around the R axis so as to enable the lens of the camera model to be lifted.
In step 207, the maximum angle by which the angle of view is rotatable in the direction of rotation of the angle of view is obtained, and the maximum distance by which the second operation is slidable in the current sliding direction is obtained.
For example, if the maximum angle rotatable in the viewing angle rotation direction is 90 °, and the maximum distance slidable in the current sliding direction by the sliding operation 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, the 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 °, the distance ratio is 1/3, the angle of view rotation is 90 ° ×1/3=30°.
In step 209, a target orientation of the viewing angle is determined based on the viewing angle rotation direction and the viewing angle rotation angle.
When the visual angle rotation angle is determined, the lens of the camera model can be controlled to rotate according to the visual angle rotation angle, and the specific rotation mode can rotate around the R axis, so that the lens of the camera model is lifted.
In step 210, if a sliding operation moving from the designated area to the view angle height control is detected, a stay time of the sliding operation within the view angle height control is obtained.
In order to avoid that the lens lifting angle is too high, the user passes through the first control when performing the sliding operation in the opposite direction, so that the lens lifting angle is not adjusted but the camera model is moved, a preset duration may be set, and how to adjust the view angle of the target object may be further determined by comparing the size relationship between the residence duration of the second operation in the view angle height control 121 and the preset duration. Thus, in this step, the stay length of the sliding operation within the view angle height control is acquired, for example, 4s.
In step 211, the residence time is compared with a preset time to obtain a comparison result.
For example, the preset time length is 5s, the stay time length is 4s, and the comparison result is that the stay time length is smaller than the preset time length; if the residence time is 6s, the comparison result is that the residence time is longer than the preset time.
In step 212, if the comparison result is that the stay time length is longer than the preset time length, the height of the viewing angle perpendicular to the designated plane is adjusted.
If the stay time length is longer than the preset time length, the vertical height of the camera model on the appointed plane can be judged to be adjusted currently by the user.
In step 213, if the comparison result is that the residence time is less than the preset time, it is determined whether the second operation is detected.
If the stay time is less than the preset time, it is impossible to determine what adjustment mode the user wants to perform currently, so as to determine whether a sliding operation of moving the view angle height control to the designated area is detected.
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 gui is returned until the second operation cannot be detected. .
And 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.
As can be seen from the above, the embodiment of the present application provides a first viewing angle control area and a second viewing angle control area through the gui, where the second viewing angle control area includes a viewing angle height control; responding to the touch operation acted on the first visual angle control area, and adjusting the projection position of the visual angle on the appointed plane; adjusting a height of the viewing angle perpendicular to the designated plane in response to a first operation acting on the viewing angle height control; the orientation of the viewing angle is adjusted in response to a second operation initiated at the viewing angle height control and acting on the designated area. Therefore, by carrying out different operations on the visual angle height control, various different visual angle adjusting functions (adjusting the visual angle height and the visual angle direction) are realized, the complexity of visual angle adjusting operation is reduced, and the visual angle adjusting efficiency is improved.
