Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention provides a method and a device for switching visual angles and a computer readable storage medium. The viewing angle switching device may be integrated in an electronic device, and the electronic device may be a server or a terminal.

The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as cloud service, a cloud database, cloud computing, a cloud function, cloud storage, Network service, cloud communication, middleware service, domain name service, security service, Network acceleration service (CDN), big data and an artificial intelligence platform. The terminal may be, but is not limited to, a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, and the like. The terminal and the server may be directly or indirectly connected through wired or wireless communication, and the application is not limited herein.

For example, referring to fig. 1, taking an example that the viewing angle switching device is integrated in the electronic device, the electronic device displays a game picture at a current viewing angle, where the current viewing angle includes an object viewing angle and a scene viewing angle, the game picture includes a viewing angle switching control, a virtual object acquired at the object viewing angle and a virtual scene acquired at the scene viewing angle, and in response to a viewing angle switching operation for the viewing angle switching control, a viewing angle parameter of the current viewing angle is acquired, then a switching type of the viewing angle switching operation is determined according to the viewing angle parameter, and then the object viewing angle and the scene viewing angle are adjusted based on the switching type, so as to obtain a target viewing angle, and a target game picture at the target viewing angle is switched and displayed.

The game screen may be a game screen corresponding to a shooting game, and the shooting game may include all games that use hot weapons to perform remote attacks, such as a First-person shooting game (FPS) and a third-person shooting game.

The field of view (FOV) is also commonly referred to as an angular field of view (anglioview), and mainly refers to an angular range in which a camera can receive images in a general environment. In an optical instrument, a lens of the optical instrument is used as a vertex, an included angle is formed by two edges of the maximum range through which an object image of a measured object can pass through the lens, and the visual angle can be called as a visual angle. The size of the field angle determines the field range of the optical instrument, and the larger the field angle, the larger the field of view, and the smaller the optical magnification. In colloquial terms, the object is not captured in the lens beyond this angle, meaning that the object is not present in the field of view.

The visual angle switching can be understood as changing the visual angle, for example, in a shooting game, the sighting telescope is opened and closed, when the sighting telescope is opened, the visual angle needs to be changed from large to small, so that the sighting telescope can be more clearly focused on other players needing to be attacked, after the attacking is completed, the sighting telescope needs to be closed, at the moment, the visual angle needs to be changed from small to large, so that the surrounding environment can be more accurately seen, and the sighting telescope is used for defending or avoiding the attack of other players and the like.

Wherein, in response to the condition or state indicating that the executed operation depends on, when the dependent condition or state is satisfied, the executed operation or operations may be in real time or may have a set delay; there is no restriction on the order of execution of the operations performed unless otherwise specified.

The following are detailed descriptions. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

In this embodiment, a description will be given of a perspective switching device, which may be specifically integrated in an electronic device, where the electronic device may be a server or a terminal; the terminal may include a tablet Computer, a notebook Computer, a Personal Computer (PC), a wearable device, a virtual reality device, or other smart devices capable of switching viewing angles.

A method of view switching, comprising:

displaying a game picture under a current visual angle, wherein the current visual angle comprises an object visual angle and a scene visual angle, the game picture comprises a visual angle switching control, a virtual object acquired under the object visual angle and a virtual scene acquired under the scene visual angle, responding to the visual angle switching operation aiming at the visual angle switching control, acquiring the visual angle parameter of the current visual angle, determining the switching type of the visual angle switching operation according to the visual angle parameter, adjusting the object visual angle and the scene visual angle based on the switching type, obtaining a target visual angle, and switching and displaying the target game picture under the target visual angle.

As shown in fig. 2, the specific flow of the method for switching the viewing angle is as follows:

101. and displaying the game picture at the current visual angle.

The current view angle may include an object view angle and a scene view angle, and therefore, a game picture at the current view angle is mainly formed by acquiring a virtual object and a virtual scene through the object view angle and the scene view angle by using two different cameras, as shown in fig. 3.

The game screen includes a view switching control, a virtual object collected from an object view, and a virtual scene collected from a scene view, for example, taking a game as a shooting game as an example, the game screen may be as shown in fig. 4, and includes a virtual object 41, a virtual scene 42, and a view switching control 43.

The object view angle may be a view angle for capturing a virtual object by a first camera mounted behind a single character object of a player, the object view angle is mainly used for capturing a virtual object in a game picture, and after the first camera captures the virtual object through the object view angle, an image of the captured virtual object may be displayed in the game picture, wherein, as shown in fig. 4, the virtual object 41 may be a partial or whole object of the character object of the player and a selected gun. The scene view angle may be a view angle used for capturing a virtual scene by a second camera mounted behind a single character of a player, and the scene view angle is mainly used for capturing the virtual scene in a game picture, and when the second camera completes capturing the virtual scene through the scene view angle, an image of the captured virtual scene may be displayed in the game picture, where, as shown in fig. 4, the virtual scene 42 may be a scene other than a player character object and a selected firearm in the game picture, and the virtual scene may include an external environment, a building, a vehicle, other player objects, and the like.

For example, the player may operate a user operation page of the game client to trigger the game client to display the game screen at the current viewing angle, for example, the player may trigger the game screen at the current viewing angle to display by operating a login page of the game client. Where the login page may include entry controls for the player's account number and password, and login controls. A player inputs an account and a password through an input control, then a login control is triggered, at the moment, a player setting page can be displayed at a game client side, the player setting page can comprise a player character selection control, a firearm selection control, a game map selection control and a game starting control, each game map corresponds to a game virtual scene, and after the player selects a player character, a firearm and a game map, the game starting control is triggered, and a game picture at the current view angle can be displayed at the game client side.

102. And responding to the visual angle switching operation aiming at the visual angle switching control, and acquiring the visual angle parameter of the current visual angle.

The view angle parameter may include view angle values of an object view and a scene view angle in the game picture at the current view angle, and may also be understood as a FOV value of the object view and the scene view angle in the game picture at the current time, that is, a value of the field angle.

For example, when a player needs to open or close a sighting telescope or switch a mechanical sighting telescope during a game, at this time, a current viewing angle in a game picture needs to be switched, and at this time, the player can perform a viewing angle switching operation on the current viewing angle by triggering a viewing angle switching control. And responding to the switching operation aiming at the visual angle switching control, acquiring the visual angle values of the object visual angle and the scene visual angle in the game picture under the current visual angle and the game engine type corresponding to the game picture, and taking the visual angle values of the object visual angle and the scene visual angle as the initial visual angle parameters of the current visual angle. The game engine refers to a core component of some written editable computer game systems or some interactive real-time image application programs. These systems provide game designers with the various tools required to compose games, with the goal of allowing game designers to easily and quickly program games without starting from zero. Most support various operating platforms, such as Linux, Mac OS X, microsoft Windows. The game engine comprises the following systems: rendering engines (i.e., "renderers," including two-dimensional and three-dimensional graphics engines), physics engines, collision detection systems, sound effects, scripting engines, computer animation, artificial intelligence, network engines, and scene management.

Comparing the game engine type corresponding to the obtained game page with a preset engine type, and when the game engine type is the same as the preset game engine type, taking the initial view angle parameter as the view angle parameter of the current view angle, for example, taking the type of the preset game engine as a nonreal (a game engine) as an example, and when the type of the game engine corresponding to the game picture is also nonreal, at this time, the initial view angle parameter can be directly taken as the view angle parameter of the current view angle. When the game engine type is different from the preset game engine type, the initial view angle parameter is converted into a target view angle parameter corresponding to the preset game engine type, for example, also taking the preset game engine type as unity, when the game engine type corresponding to the game picture is unity (another game engine), at this time, the game engine type corresponding to the game picture is different from the preset game engine type, the initial view angle parameter under unity needs to be converted into the target view angle parameter under unity, and the converted target view angle parameter can be used as the view angle parameter of the current view angle. The specific conversion formula can be shown as formula (1), and specifically can be as follows:

wherein x is an initial view parameter in unity, and y is a target view parameter in unity.

103. And determining the switching type of the visual angle switching operation according to the visual angle parameters.

Here, the switching type may be understood as a type of changing the current view, for example, the view parameter of the current view may be changed from small to large or from small to large, and thus, the switching type may include increasing view switching and decreasing view switching. The increasing of the view angle switching may be to switch the current view angle to a view angle larger than the current view angle, and the decreasing of the view angle switching may be to switch the current view angle to a view angle smaller than the current view angle, for example, taking switching of the view angle as turning on or turning off the scope, the switching type corresponding to the change of the view angle parameter of the current view angle from small to large may be to turn off the scope, and conversely, the switching type corresponding to the change of the view angle parameter of the current view angle from large to small may be to turn on the scope.

For example, a preset view parameter threshold for determining the switching type may be obtained, for example, the preset view parameter threshold may include a preset object view threshold and a preset scene view threshold. The view angle parameter of the current view angle is compared with a preset view angle parameter threshold, for example, an object view angle value and a scene view angle value can be extracted from the view angle parameter, the object view angle value is compared with the preset object view angle threshold, and the scene view angle value is compared with the preset scene view angle threshold.

When the view angle parameter exceeds the preset view angle parameter threshold, determining that the switching type of the view angle switching operation is reduced view angle switching, for example, when any one of the object view angle value and the scene view angle value exceeds the corresponding preset view angle parameter threshold, for example, when the object view angle value exceeds the preset object view angle threshold and the scene view angle value also exceeds the preset scene view angle threshold, determining reduced view angle switching of the switching type of the view angle switching operation; or, when the object view value exceeds the preset object view value and the scene view value does not exceed the preset scene view threshold, the switching type of the view switching operation may be determined to be reduced view switching; alternatively, when the object view value does not exceed the preset object view value and the scene view value exceeds the preset scene view threshold, the switching type of the view switching operation may also be determined to be reduced view switching.

When the view angle parameter does not exceed the preset view angle parameter threshold, it is determined that the switching type of the view angle switching operation is switching of the increased view angle, for example, when the object view angle value does not exceed the preset object view angle threshold and the scene view angle value does not exceed the preset scene view angle threshold, at this time, it may be determined that the switching type of the view angle switching operation is switching of the increased view angle.

104. And adjusting the object visual angle and the scene visual angle based on the switching type to obtain the target visual angle.

The adjustment of the object view angle and the scene view angle may be understood as changing view angle values of the object view angle and the scene view angle, that is, changing FOV values of the object view angle and the scene view angle.

For example, a first view value of an object view and a second view value of a scene view may be screened from the view parameters, and the first view value and the second view value may be adjusted based on the switching type to obtain a target view, which may specifically be as follows:

and S1, screening out a first view angle value of the object view angle and a second view angle value of the scene view angle from the view angle parameters.

For example, a first view angle value of the object view angle and a second view angle value of the scene view angle are screened out from the view angle parameters, for example, the object view angle value of the object view angle and the scene view angle value of the scene view angle may be screened out from the view angle parameters, and the object view angle value and the scene view angle value may be respectively used as the first view angle value and the second view angle value.

And S2, adjusting the first visual angle value and the second visual angle value based on the switching type to obtain a target visual angle value.

For example, an adjustment type for adjusting the first view value and the second view value and the target view value may be determined based on the switching type, wherein the adjustment type may be a view increasing adjustment and a view decreasing adjustment. For example, when the switching type is switching to increase the angle of view, it may be determined that the adjustment type for adjusting the first angle of view value and the second angle of view value is adjustment to increase the angle of view, and conversely, when the switching type is switching to decrease the angle of view, it may be determined that the adjustment type for adjusting the first angle of view value and the second angle of view value is adjustment to decrease the angle of view. And screening out a target view angle value which needs to be adjusted according to the first view angle value and the second view angle value from the game view angle data set according to the switching type, wherein the target view angle value can comprise a target view angle value of an object view angle and a target view angle value of a scene view angle, and the target view angle value of the object view angle and the target view angle value of the scene view angle can be the same or different.

And adjusting the first view angle value and the second view angle value to a target view angle value according to the adjustment type to obtain a target view angle. The adjustment types may include a viewing angle increase adjustment and a viewing angle decrease adjustment, which are specifically described below:

and C1, when the adjustment type is the visual angle increasing adjustment, adding the first visual angle value and the second visual angle value to the target visual angle value to obtain the target visual angle.

For example, when the adjustment type is view increase adjustment, the first view value and the second view value are compared, when the first view value and the second view value are the same, the first view value and the second view value can be directly added to the target view value to obtain the target view value, the view corresponding to the target view value is used as the target view, for example, when the target view value is 90, the first view value and the second view value are 35, the first view value and the second view value can be increased from 35 to 90 by using a constant speed or a non-constant speed to obtain the target view.

When the first view angle value and the second view angle value are different, a first view angle difference value between the first view angle value and the second view angle value is calculated, then, based on the first view angle difference value, the first view angle value and the second view angle value are added to a target view angle value, for example, when the first view angle value exceeds the second view angle value, based on the first view angle value, the first view angle value is adjusted to be the same as the first view angle value, and the adjusted second view angle value and the first view angle value are added to the target view angle value. Adding the adjusted second view angle value and the adjusted first view angle value to the target view angle value to obtain the target view angle, for example, calculating a second view angle difference between the first view angle value and the target view angle value, determining an increase speed of adding the adjusted second view angle value and the adjusted first view angle value to the target view angle value according to the second view angle value, and adding the adjusted second view angle value and the adjusted first view angle value to the target view angle value based on the increase speed to obtain the target view angle.

Optionally, when the first viewing angle value does not exceed the second viewing angle value, at this time, the first viewing angle value is adjusted to be equal to the second viewing angle value only by using the same method, and then the adjusted first viewing angle value and second viewing angle value are added to the target viewing angle value together, so that the target viewing angle can be obtained. The adjustment speed and the increase speed are also determined by using the difference between the first viewing angle value and the second viewing angle and the difference between the second viewing angle value and the target viewing angle value, in the same manner as the above method.

Wherein, in case that the first and second viewing angle values are different, the first and second viewing angle values are added to the target viewing angle, to illustrate a specific example, for example, taking the first viewing angle value 35, the second viewing angle value 45, and the target viewing angle value 75 as examples, the difference between the first viewing angle value and the second viewing angle value is first calculated to be 10, then, based on the difference 10, an adjustment speed for adjusting the first viewing angle value to 45, which may be a constant speed or a variable speed, then, the first viewing angle value is adjusted to 45 according to the adjustment speed, then, the difference value between the second viewing angle value and the target viewing angle value is calculated to be 30, and it is determined that the adjusted first viewing angle value 45 and the first viewing angle value 45 are simultaneously increased to 75 according to the difference value 30, at this time, the viewing angle corresponding to the first viewing angle value and the second viewing angle value, which are both 75, may be taken as the target viewing angle.

And C2, when the adjustment type is view angle reduction adjustment, reducing the first view angle value and the second view angle value to the target view angle value to obtain the target view angle.

For example, when the adjustment type is viewing angle reduction adjustment, the first viewing angle value and the second viewing angle value are compared, and when the first viewing angle value and the second viewing angle value are the same, the first viewing angle value and the second viewing angle value are reduced to the target viewing angle value, for example, when the first viewing angle value and the second viewing angle value are both 75 and the target viewing angle value is 35, the first viewing angle value and the second viewing angle value are directly reduced to 35 at a constant speed or a variable speed, and the viewing angle corresponding to the first viewing angle value and the second viewing angle value with the viewing angle value of 35 is taken as the target viewing angle. The speed of change for reducing the first and second view angle values to 35 may be determined from the difference between the first or second view angle value and the target view angle value.

Alternatively, when the first view angle value and the second view angle value are different, a third view angle difference value between the first view angle value and the second view angle value may be calculated, and then, the first view angle value and the second view angle value may be reduced to the target view angle value based on the third view angle difference value, for example, when the first view angle value exceeds the second view angle value, a first reduction speed at which the first view angle value is reduced to the second view angle value may be determined according to the third view angle difference value, and then, the first view angle value may be reduced to the second view angle value at the first reduction speed. And continuously calculating a fourth visual angle difference value of the first visual angle value and the target visual angle value, determining a second reduction speed for reducing the first visual angle value and the reduced second visual angle value to the target visual angle value according to the fourth visual angle difference value, then continuously adopting the second reduction speed, reducing the first visual angle value and the reduced second visual angle value to the target visual angle value, and taking the visual angle corresponding to the first visual angle value and the second visual angle value reduced to the target visual angle value as the target visual angle, thereby obtaining the target visual angle.

When the first view angle value does not exceed the second view angle value, the method may be adopted to reduce the second view angle value to the first view angle value, and then reduce the first view angle value and the reduced second view angle value together to the target view angle value, and the reduction speeds of the two times may be determined based on the third view angle difference and the fourth view angle difference, respectively.

The first reduction speed and the second reduction speed may be the same or different, and the first reduction speed and the second reduction speed may be constant or variable.

105. And switching and displaying the target game picture under the target visual angle.

For example, the virtual object and the virtual scene at the target view angle may be collected to obtain the target game picture, for example, the target virtual object at the object view angle adjusted to the target view angle value may be collected by the first camera, the target virtual scene at the scene object view angle adjusted to the target view angle value may be collected by the second camera, the virtual object in the game picture may be replaced by the target virtual object, and the virtual scene in the game picture may be replaced by the target virtual object, so that the target game picture at the target view angle may be obtained. And switching the game picture to a target game picture, for example, switching the game picture displayed on the game client under the current visual angle to the target game picture under the target visual angle, thereby completing the visual angle switching in the game picture.

As can be seen from the above, in the embodiments of the present invention, after a game picture at a current viewing angle is displayed, the current viewing angle includes an object viewing angle and a scene viewing angle, the game picture includes a viewing angle switching control, a virtual object collected at the object viewing angle, and a virtual scene collected at the scene viewing angle, a viewing angle parameter of the current viewing angle is obtained in response to a viewing angle switching operation for the viewing angle switching control, a switching type of the viewing angle switching operation is determined according to the viewing angle parameter, the object viewing angle and the scene viewing angle are adjusted based on the switching type to obtain a target viewing angle, and a target game picture at the target viewing angle is switched and displayed, because the scheme collects the virtual object and the virtual scene through the object viewing angle and the scene viewing angle provided by different cameras, the virtual object viewing angle and the virtual scene are in pictures corresponding to different viewing angles, and when the viewing angle is switched, the object viewing angle and the scene are respectively adjusted, therefore, the flexibility of the display range of the virtual scene and the virtual object after the visual angle is switched is greatly improved, and the display effect of the picture after the visual angle is switched can be greatly improved.

The method described in the above examples is further illustrated in detail below by way of example.

In this embodiment, the visual angle switching device is specifically integrated in an electronic device, the electronic device is a terminal, a game corresponding to a game screen is an FPS game, a visual angle switching control is an aiming control, and switching types are closing of an aiming lens (hereinafter, referred to as closing of a lens) and opening of the aiming lens (hereinafter, referred to as opening of a lens) for example.

As shown in fig. 5, a method for switching a viewing angle specifically includes the following steps:

201. and the terminal displays the game picture at the current visual angle.

For example, a player may operate a login page of a game client to trigger the terminal to display a game screen at a current viewing angle, for example, the player inputs an account and a password through an input control, and then triggers the login control, the terminal may display a player setting page at the game client, the player may select a player character, a gun, and a game map on the player setting page, and then trigger a start game control, and the terminal may display the game screen at the current viewing angle.

202. And the terminal responds to the visual angle switching operation aiming at the aiming control to acquire the visual angle parameter of the current visual angle.

For example, when a player needs to perform an operation of opening or closing the mirror during a game, the player can perform a switching operation on the current viewing angle by triggering the aiming control. The terminal responds to the switching operation aiming at the aiming control, can acquire the visual angle values of the object visual angle and the scene visual angle in the game picture under the current visual angle and the game engine type corresponding to the game picture, and takes the visual angle values of the object visual angle and the scene visual angle as the initial visual angle parameters of the current visual angle. Comparing the game engine type corresponding to the acquired game page with a preset engine type, taking the preset game engine type as nonreal as an example, when the game engine type corresponding to the game picture is nonreal, at this time, the initial view angle parameter can be directly used as the view angle parameter of the current view angle; when the game engine type corresponding to the game screen is unity, the initial perspective parameter in unity needs to be converted into the target perspective parameter in unity, and the converted target perspective parameter can be used as the perspective parameter of the current perspective, and the specific conversion formula can be referred to as formula (1).

203. And the terminal determines the switching type of the visual angle switching operation according to the visual angle parameters.

For example, the terminal may obtain a preset view parameter threshold for determining the switching type, where the preset parameter threshold may include a preset object view threshold and a preset scene view threshold, extract an object view value and a scene view value from the view parameter, compare the object view value with the preset object view threshold, and compare the scene view value with the preset scene view threshold.

When any one of the object view angle value and the scene view angle value exceeds a corresponding preset view angle parameter threshold, for example, when the object view angle value exceeds a preset object view angle threshold and the scene view angle value also exceeds a preset scene view angle threshold, a switching type of the view angle switching operation can be determined to be turned off; or, when the object view value exceeds the preset object view value and the scene view value does not exceed the preset scene view threshold, the switching type of the view switching operation may also be determined to be off; or, when the object view value does not exceed the preset object view value and the scene view value exceeds the preset scene view threshold, the switching type of the view switching operation may also be determined to be off.

When the object view angle value does not exceed the preset object view angle threshold value and the scene view angle value does not exceed the preset scene view angle threshold value, the switching type of the view angle switching operation can be determined to be open mirror.

204. And the terminal screens out a first view angle value of the object view angle and a second view angle value of the scene view angle from the view angle parameters.

For example, the terminal may screen an object view value of the object view and a scene view value of the scene view from the view parameters, and use the object view value as a first view value and the scene view value as a second view value, respectively.

205. The terminal determines an adjustment type and a target view value for adjusting the first view value and the second view value based on the switching type.

For example, when the switching type is on-mirror, the terminal may determine that the adjustment type for adjusting the first view angle value and the second view angle value is view angle increase adjustment, and conversely, when the switching type is off-mirror, the terminal may determine that the adjustment type for adjusting the first view angle value and the second view angle value is view angle decrease adjustment. And screening out a target view angle value which needs to be adjusted according to the first view angle value and the second view angle value from the game view angle data set according to the switching type, wherein the target view angle value can comprise a target view angle value of an object view angle and a target view angle value of a scene view angle, and the target view angle value of the object view angle and the target view angle value of the scene view angle can be the same or different.

206. And when the adjustment type is visual angle increasing adjustment, the terminal increases the first visual angle value and the second visual angle value to the target visual angle value to obtain the target visual angle.

For example, when the adjustment type is view increase adjustment, the terminal needs to compare the first view value with the second view value, and increase the first view value and the second view value to the target view value according to the comparison result, so as to obtain the target view, which may specifically be as follows:

(1) the first viewing angle and the second viewing angle have the same value.

For example, when the first angle of view and the second angle of view are the same, the terminal may directly add the first angle of view and the second angle of view to the target angle of view, so as to obtain a target angle of view, take the angle of view corresponding to the target angle of view as the target angle of view, for example, take the first angle of view and the second angle of view as 35 and the target angle of view as 75, directly add the first angle of view and the second angle of view to 75 at a constant speed or at a variable speed, and take the angle of view corresponding to the first angle of view and the second angle of view as the target angle of view, where the angle of view is 75.

(2) The first viewing angle is different from the second viewing angle.

For example, when the first view angle value and the second view angle value are different, a first view angle difference value between the first view angle value and the second view angle value is calculated, when the first view angle value exceeds the second view angle value, an adjustment speed for adjusting the second view angle value is determined according to the first view angle difference value, and the second view angle value is adjusted based on the adjustment speed so that the adjusted second view angle value is the same as the first view angle value. And calculating a second visual angle difference value between the first visual angle value and the target visual angle value, determining the increasing speed of increasing the adjusted second visual angle value and the adjusted first visual angle value to the target visual angle value according to the second visual angle value, and increasing the adjusted second visual angle value and the adjusted first visual angle value to the target visual angle value based on the increasing speed to obtain the target visual angle.

Optionally, when the first viewing angle value does not exceed the second viewing angle value, at this time, the first viewing angle value is adjusted to be equal to the second viewing angle value only by using the same method, and then the adjusted first viewing angle value and second viewing angle value are added to the target viewing angle value together, so that the target viewing angle can be obtained. The adjustment speed and the increase speed are also determined by the difference between the first viewing angle value and the second viewing angle and the difference between the second viewing angle value and the target viewing angle value.

207. And when the adjustment type is visual angle reduction adjustment, the terminal reduces the first visual angle value and the second visual angle value to a target visual angle value to obtain a target visual angle.

For example, when the adjustment type is view reduction adjustment, the terminal needs to compare the first view value with the second view value, and reduce the first view value and the second view value to the target view value according to the comparison result, so as to obtain the target view, which may specifically be as follows:

(1) the first viewing angle value and the second viewing angle value are the same.

For example, when the first view angle value and the second view angle value are the same, the terminal may reduce the first view angle value and the second view angle value to the target view angle value, and take the view angle corresponding to the target view angle value as the target view angle, for example, taking the first view angle value and the second view angle value as 75 and the target view angle value as 35 as an example, directly reduce the first view angle value and the second view angle value to 35 at a constant speed or at a variable speed, and take the view angle corresponding to the first view angle value and the second view angle value with the view angle value of 35 as the target view angle.

(2) The first view value and the second view value are different.

For example, when the first viewing angle value and the second viewing angle are different and the first viewing angle value exceeds the second viewing angle value, the terminal may calculate a third viewing angle difference value between the first viewing angle value and the second viewing angle value, determine a first reduction speed at which the first viewing angle value is reduced to the second viewing angle value based on the third viewing angle difference value, and then reduce the first viewing angle value to the second viewing angle value using the first reduction speed. And continuously calculating a fourth visual angle difference value of the first visual angle value and the target visual angle value, determining a second reduction speed for reducing the first visual angle value and the reduced second visual angle value to the target visual angle value according to the fourth visual angle difference value, then continuously adopting the second reduction speed, reducing the first visual angle value and the reduced second visual angle value to the target visual angle value, and taking the visual angles corresponding to the first visual angle value and the second visual angle value reduced to the target visual angle value as target visual angles so as to obtain the target visual angles.

Optionally, when the first view angle value and the second view angle value are different and the first view angle value does not exceed the second view angle value, the terminal may also reduce the second view angle value to the first view angle value by using the above method, and then reduce the first view angle value and the reduced second view angle value together to the target view angle value, where the reduction speeds of the two times may be determined based on the third view angle difference value and the fourth view angle difference value, respectively.

208. And the terminal switches and displays the target game picture under the target visual angle.

For example, the terminal may acquire, by the first camera, a target virtual object at an object viewing angle adjusted to a target viewing angle value, acquire, by the second camera, a target virtual scene at a scene object viewing angle adjusted to the target viewing angle value, replace the virtual object in the game screen with the target virtual object, and replace the virtual scene in the game screen with the target virtual object, thereby obtaining a target game screen at the target viewing angle. And switching the game picture displayed on the terminal at the current visual angle into a target game picture at the target visual angle, thereby completing the process of single mirror opening or closing operation of the player.

The process of completing the single mirror opening or closing by the player may be as shown in fig. 6, and the specific process may also be understood as that after the player triggers the aiming control, it needs to determine whether the view angle switching is in the change from mirror opening to mirror closing or in the change from mirror closing to mirror opening, that is, the mirror opening or mirror closing in the switching type, and the mirror opening is in the change from mirror closing to mirror opening, and similarly, the mirror closing is in the change from mirror opening to mirror closing. And then, acquiring two cameras according to a blueprint and a scene blueprint configured on the virtual object and the firearm, wherein the first camera corresponds to the virtual object and the firearm, and the second camera corresponds to the virtual scene, and judging whether the view angle values of the two cameras are consistent at the current moment according to the current FOV values of the two cameras, namely the first view angle value and the second view angle value.

For example, taking fig. 7 as an example of a mirror closing operation, the viewing angle parameter of the current viewing angle of the image (a) in fig. 7 may be that the first viewing angle value is 91.5, the second viewing angle value is 80, and the target viewing angle value of the target viewing angle of the image (b) in fig. 7 is 75, at this time, the first viewing angle value is changed at a constant speed or at a variable speed by using a certain speed (which may be determined or preset according to a difference between the first viewing angle value and the second viewing angle value), and when the first viewing angle value changes to a time equal to 80, the first viewing angle value and the second viewing angle value change to 75. When the two cameras finish moving, the process of opening or closing the mirror once can be finished, and at the moment, the game picture displays the virtual object and the virtual scene which are acquired by the two cameras under the target view angle value.

As can be seen from the above, after the terminal of this embodiment displays a game picture at a current viewing angle, where the current viewing angle includes an object viewing angle and a scene viewing angle, the game picture includes a viewing angle switching control, a virtual object collected at the object viewing angle, and a virtual scene collected at the scene viewing angle, acquires a viewing angle parameter of the current viewing angle in response to a viewing angle switching operation for the viewing angle switching control, determines a switching type of the viewing angle switching operation according to the viewing angle parameter, adjusts the object viewing angle and the scene viewing angle based on the switching type to obtain a target viewing angle, and switches and displays a target game picture at the target viewing angle, because the scheme collects the virtual object and the virtual scene through the object viewing angle and the scene viewing angle provided by different cameras, the virtual object and the virtual scene are in pictures corresponding to different viewing angles, and when the viewing angle is switched, the object viewing angle and the scene are respectively adjusted, therefore, the flexibility of the display range of the virtual scene and the virtual object after the visual angle is switched is greatly improved, and the display effect of the picture after the visual angle is switched can be greatly improved.
