In the present specification, a focusing method is provided, and the present specification relates to a focusing apparatus, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

Fig. 1 shows a flowchart of a focusing method provided in an embodiment of the present specification, which specifically includes the following steps:

step 102: a target object in the display image is determined, and an envelope box of the target object is determined.

In practical application, with the rapid development of computer technology, image display is closely related to people's life and work, and when a user works and entertains through an intelligent device, an image picture is displayed on an interface of the intelligent device, and the image picture comprises various objects. Generally, a focal distance is set for all objects in an image frame for observation, however, the distances and sizes between the objects are different, some objects in the observed image frame are clear and some objects may be blurred through the set focal distance, and when a certain object in the image frame needs to be observed carefully, the details of the object may not be seen clearly.

The focusing method provided by the specification can determine a target object in a display image and determine an envelope box of the target object; then, adjusting the center point of the envelope box along the diagonal direction of the envelope box; adding an observation camera to the target object at the adjusted central point, and determining the shooting posture of the observation camera according to the target area of the target object; and then controlling the observation camera to observe the target object in the shooting posture. In this case, if a target object in the display image is desired to be observed in detail, the observation position of the observation camera of the target object may be determined according to the size of the target object, an observation camera is added to the observation position for the target object, the observation angle of the observation camera is determined according to the target area to be observed, and then the observation camera is controlled to observe the target object at the observation angle at the observation position, so that, for any object in the display image, if the details of the object are desired to be observed carefully, the object may be clearly displayed by adding the observation camera to the object at the corresponding position, thereby ensuring that each object in the display image can be observed clearly.

Specifically, the display image is an image currently displayed by the terminal device, the display image may include at least one object, and the target object is any one of the at least one object included in the display image, where the object refers to an object and/or a person included in the display image. The envelope box of the target object refers to a quadrangular prism shape which just can wrap the target object, and the size of the envelope box represents the size of the target object.

In an optional implementation manner of this embodiment, a corresponding selection control may be set in advance for each object included in the display image, when a user wants to carefully observe an object in the display image, the selection control corresponding to the object is triggered, and the object is determined as a target object, where a specific implementation process for determining the target object in the display image may be as follows:

receiving a selection instruction for an object included in a display image;

It should be noted that the selection instruction is an instruction triggered by an operation of selecting a certain object, where the operation of selecting the object may be clicking the object, clicking a selection control corresponding to the object, or selecting a function option triggered by a right key.

In the description, for any object in the display image, if the user wants to carefully observe an object in the display image, the user can select the object, so that an observation camera can be added to the object at a corresponding position in the following process, the object is clearly displayed, and each object in the display image can be clearly observed.

Further, if the selected target object has been selected previously, the observation position to which the observation camera is added and the shooting posture of the observation camera should have been previously determined for the target object, so that the stored observation position (center point) and shooting posture can be directly obtained without performing subsequent operations of determining the envelope box of the target object, thereby determining the observation position, and thus after determining the target object in the display image and before determining the envelope box of the target object, it can also be determined whether the target object has been selected previously, which is implemented as follows:

In the specific implementation process, a corresponding relation table among the object identifier, the central point and the shooting posture can be stored in advance, after the target object is determined, the object identifier of the target object is searched in the corresponding relation table among the object identifier, the central point and the shooting posture, and if the object identifier of the target object can be searched, the central point and the shooting posture corresponding to the searched object identifier are determined as the target central point and the target shooting posture; and if the object identification of the target object cannot be found, determining that the target object does not have a corresponding target central point and a corresponding target shooting posture.

For example, the table of correspondence between the pre-stored object identifier, the center point, and the shooting posture is shown in table 1 below, assuming that the determined target object is object 2 and the object identifier of object 2 is B identifier, the object identifier of object 2 is found in the table of correspondence between the object identifier, the center point, and the shooting posture shown in table 1 below, at this time, the B center point and the B shooting posture corresponding to the B identifier in table 1 below are determined as the target center point and the target shooting posture of object 2, an observation camera is subsequently added to object 2 directly at the B center point, and the observation camera is controlled to observe object 2 in the B shooting posture. Or, assuming that the determined target object is the object 4, the object identifier of the object 4 is a D identifier, and the object identifier of the object 4 is not found in the correspondence table among the object identifier, the central point, and the shooting posture shown in the following table 1, at this time, the operation step of subsequently determining the envelope box of the object 4 is continuously performed.

TABLE 1 table of correspondences between object identifiers, center points and photographing postures

Object identification	Center point	Shooting posture
			A sign	Center point A	Posture of A shooting
B sign	Center point of B	Posture of B shooting
			C mark	Center point of C	C shooting attitude

It is worth mentioning that if the target object has the corresponding target center point and the corresponding target shooting posture, the target center point and the target shooting posture corresponding to the target object can be directly obtained, the observation camera is added to the target object at the target center point, the observation camera is controlled to observe the target object in the target shooting posture, subsequent determination steps are not needed, and for the same target object, the observation position where the observation camera is added to the same target object and the shooting posture of the observation camera do not need to be repeatedly determined, so that repeated useless operation is avoided, the efficiency of observing the target object is improved, and processing resources are saved.

Step 104: and adjusting the center point of the envelope box along the diagonal direction of the envelope box.

Specifically, on the basis of determining a target object in a display image and determining an envelope box of the target object, the center point of the envelope box is further adjusted along the body diagonal direction of the envelope box. The body diagonal line of the envelope box is a connecting line connecting two vertexes of the upper bottom surface and the lower bottom surface of the envelope box, which are not on the same side surface.

In an optional implementation manner of this embodiment, because the envelope box is in a quadrangular prism shape, there should be 4 body diagonals in the envelope box, and a body diagonal can be arbitrarily selected from the 4 body diagonals to adjust the center point of the envelope box, so that the center point of the envelope box is adjusted along the direction of the body diagonal of the envelope box, and the specific implementation process may be:

determining a target adjusting direction for adjusting along a diagonal line of a target body, wherein the target adjusting direction is a forward direction or a reverse direction of the diagonal line of the target body;

and adjusting the target distance of the central point of the envelope box along the target adjusting direction, wherein the target distance is a preset multiple of the length of the body diagonal.

Specifically, the center point of the envelope box is adjusted by a target distance, that is, the center point of the envelope box is moved by the target distance along a target adjustment direction, the target distance represents a movement distance of the center point of the envelope box, and the distance is related to the length of the body diagonal of the envelope box, wherein a specific correlation coefficient may be set, that is, the length of the body diagonal of the envelope box is a preset multiple, and the preset multiple may be set in advance, for example, 1.1, 1.2, 1.3, and the like.

It should be noted that the target body diagonal is any one of the 4 body diagonals of the envelope box. In addition, the center point divides the body diagonal into 2 segments, the center point moves along the upper half segment, i.e., moves upward, and the center point moves along the lower half segment, i.e., moves downward, i.e., one segment moves upward, the other segment moves downward, the direction is determined to be upward as the forward direction, and the direction is determined to be downward as the reverse direction. When the central point of the envelope box is actually adjusted, a target adjustment direction can be determined according to an area to be observed, if the upper half part of a target object is to be observed carefully, the forward direction can be determined as the target adjustment direction, namely, the central point of the envelope box moves upwards, so that an observation camera is arranged above the target object; if one wants to carefully observe the lower half of the target object, the reverse direction may be determined as the target adjustment direction, i.e. the center point of the envelope box is moved downwards, such that the observation camera is arranged below the target object.

In this specification, a target body diagonal line may be determined from a plurality of body diagonal lines of the envelope box, then a target adjustment direction for adjustment along the target body diagonal line is further determined, and then the center point of the envelope box is moved by a target distance along the target adjustment direction, so that an observation camera for observing the target object may be subsequently constructed around the target object, for carefully observing details of the target object.

Step 106: and adding an observation camera for the target object at the adjusted central point, and determining the shooting posture of the observation camera according to the target area of the target object.

Specifically, on the basis of adjusting the central point of the envelope box along the body diagonal direction of the envelope box, an observation camera is further added to the adjusted central point as the target object, and the shooting posture of the observation camera is determined according to the target area of the target object. The target area refers to an area to be observed carefully, such as the top, the upper half, the lower half, the bottom, and the like of a target object, the shooting posture refers to the pitch angle of the observation camera, the angle is positive and represents an upward looking angle, the angle is negative and represents a downward looking angle, and the specific angle of the pitch angle is not limited in this specification, and the pitch angle may be positive 30 degrees, positive 40 degrees, positive 60 degrees, negative 30 degrees, negative 40 degrees, negative 60 degrees, or the like.

It should be noted that, after the observation camera is added to the target object at the adjusted central point, the pitch angle of the observation camera may be determined according to the target area to be observed, and if the upper half or the top of the target object is to be observed carefully, the pitch angle of the observation camera may be set to a negative angle, that is, the observation camera looks down at the target object; if one wants to carefully observe the lower half or bottom of the target object, the pitch angle of the observation camera may be set to a positive angle, i.e., the observation camera looks up at the target object.

In addition, the target region may also be a region where the adjusted central point (the position of the observation camera) is located relative to the target object, that is, the pitch angle of the observation camera may also be determined according to the relative position of the observation camera and the target object, and if the observation camera is located above the target object, if the target object is to be observed carefully, the pitch angle of the observation camera needs to be set to a negative angle, that is, the observation camera looks down at the target object; if the observing camera is located below the target object, if the target object is intended to be observed carefully, the pitch angle of the observing camera needs to be set to a positive angle, that is, the observing camera looks up and down at the target object.

In this specification, after the observation camera is added to the target object at the adjusted central point, the shooting posture of the observation camera can be determined according to the target area of the target object, so that the observation position and the observation angle at which the target object can be carefully observed can be determined, and the target object can be clearly displayed.

In an optional implementation manner of this embodiment, a shooting posture corresponding to the target area may be stored in advance, and at this time, the shooting posture of the observation camera is determined according to the target area of the target object, and a specific implementation process may be as follows:

determining a target shooting attitude corresponding to the target area according to a corresponding relation between the pre-stored area identification and the shooting attitude;

It should be noted that, a corresponding shooting posture may be set in advance for each area identifier, and a corresponding relationship between the area identifier and the shooting posture is stored for subsequently determining the shooting posture of the observation camera. In specific implementation, the area identifier of the target area may be searched in the correspondence table between the area identifier and the shooting posture, if the area identifier of the target area can be found, the shooting posture corresponding to the found area identifier is determined as the shooting posture of the observation camera, and if the area identifier of the target area cannot be found, the default shooting posture may be determined as the shooting posture of the observation camera, where the default shooting posture may also be preset, for example, 0 degree.

For example, the table of correspondence between the pre-stored area identifier and the shooting attitude is shown in table 2 below, and assuming that the area identifier of the determined target area is the top, the area identifier of the target area is found in the table of correspondence between the area identifier and the shooting attitude shown in table 2 below, and at this time, the minus 30 degrees corresponding to the area identifier in table 2 below being the top is determined as the shooting attitude of the observation camera.

Table 2 correspondence table between area identification and shooting attitude

Region identification	Shooting posture
		On the upper part	Minus 30 degree
Lower part	Plus 30 degrees

In an optional implementation manner of this embodiment, the input shooting posture may also be received, and the shooting posture of the observation camera is determined according to the target area of the target object at this time, where the specific implementation process may be as follows:

receiving a pitch angle input for a target area;

the pitch angle is determined as the shooting attitude of the observation camera.

It should be noted that, the user may also manually input a pitch angle for the target area to control the shooting posture of the observation camera. In the present specification, the pitch angle preset for the target area may be determined as the shooting attitude of the observation camera through a pre-stored correspondence table between the area identifier and the shooting attitude, and the pitch angle input according to the actual scene may also be determined as the shooting attitude of the observation camera, and the determination manner is flexible and changeable, and is capable of adapting to different scenes, thereby ensuring the observation effect of the target object.

Furthermore, after the central point of the observation camera is determined and constructed for the target object and the shooting posture of the observation camera is determined, the central point can be correspondingly stored, so that subsequent query is facilitated.

It is worth to be noted that, in this specification, after the central point of the observation camera is determined and constructed for the target object and the shooting posture of the observation camera is determined, the corresponding relationship among the target object, the central point and the shooting posture can be stored, so that when the target object is subsequently determined, the stored central point and the shooting posture can be directly obtained, that is, for the same target object, only one time of determining the central point and the shooting posture is needed, thereby avoiding repeated useless operations, improving the efficiency of observing the target object, and saving processing resources.

Step 108: the observation camera is controlled to photograph the posture observation target object.

Specifically, on the basis that the observation camera is added to the target object at the adjusted central point and the shooting posture of the observation camera is determined according to the target area of the target object, the observation camera is further controlled to observe the target object in the shooting posture.

In an optional implementation manner of this embodiment, the observation camera is controlled to observe the target object in the shooting posture, and a specific implementation process may be as follows;

and controlling the observation camera to shoot the gesture, and acquiring and displaying the picture data of the picture where the target object is located.

It should be noted that the observation camera is constructed at the adjusted central point, so that the observation camera is actually controlled at the adjusted central point to determine the pitch angle, and the image data of the image where the target object is located is acquired and displayed.

Fig. 2 is a flowchart illustrating another focusing method provided in an embodiment of the present disclosure, which specifically includes the following steps:

step 202: receiving a selection instruction for an object included in the display image, and determining the object indicated by the selection instruction as a target object.

Step 204: whether the target object has the corresponding target center point and the target shooting posture is determined, if yes, step 212 is executed, and if not, the following step 206 and step 210 are executed.

Step 206: and determining an envelope box of the target object, and adjusting the central point of the envelope box along the body diagonal direction of the envelope box.

Step 208: and adding an observation camera for the target object at the adjusted central point, determining the shooting posture of the observation camera according to the target area of the target object, and storing the corresponding relation among the target object, the central point and the shooting posture.

Step 210: the observation camera is controlled to photograph the posture observation target object.

Step 212: directly acquiring a target central point and a target shooting posture corresponding to the target object, adding an observation camera for the target object at the target central point, and controlling the observation camera to observe the target object at the target shooting posture.

In the focusing method provided by this specification, if a target object in a display image is desired to be observed in detail, the target object may be selected, the observation position of the observation camera of the target object is determined according to the size of the target object, an observation camera is added to the observation position of the target object, the observation angle of the observation camera is determined according to a target area to be observed, and then the observation camera is controlled to observe the target object at the observation position at the observation angle.

The foregoing is a schematic solution of a focusing method according to the present embodiment. It should be noted that the technical solution of the focusing method belongs to the same concept as the technical solution of the focusing method shown in fig. 1, and details of the technical solution of the focusing method shown in fig. 2, which are not described in detail, can be referred to the description of the technical solution of the focusing method shown in fig. 1.

The following will further describe the focusing method with reference to fig. 3 by taking an application of the focusing method provided in this specification in a game scene as an example. Fig. 3 shows a processing flow chart of a focusing method applied to a game scene provided in an embodiment of the present specification, and specifically includes the following steps:

step 302: a selection instruction for an object included in the game screen is received, and the object indicated by the selection instruction is determined as a target object.

In practical applications, with the rapid development of computer technology, games have become an important part of people's entertaining life, and when a player operates a game through a game terminal, the game terminal displays a game picture related to the current game progress in real time, and the game picture includes various objects. Generally, a focal length is set for all objects in a game picture for observation, however, the distances and sizes of the objects are different, some objects in the observed game picture are clear and some objects may be blurred through the set focal length, and when a certain object in the game picture needs to be observed carefully, the details of the object may not be seen.

The focusing method provided by the present specification may receive a selection instruction for an object included in a game screen, and determine the object indicated by the selection instruction as a target object; then determining an envelope box of the target object, and adjusting the central point of the envelope box along the body diagonal direction of the envelope box; adding an observation camera to the target object at the adjusted central point, and determining the shooting posture of the observation camera according to the target area of the target object; thereafter, the observation camera is controlled to photograph the posture observation target object. In this case, if a target object in the game screen is desired to be observed in detail, the target object may be selected, the observation position of the observation camera of the target object is determined according to the size of the target object, an observation camera is added to the observation position for the target object, the observation angle of the observation camera is determined according to the target area to be observed, and then the observation camera is controlled to observe the target object at the observation angle at the observation position.

Specifically, the game screen refers to a screen currently displayed during the progress of the game, and the object refers to an article or a character displayed in the game screen.

In the description, for any object in the game picture, if a user wants to carefully observe an object in the game picture, the object can be selected, so that an observation camera can be added to the object at a corresponding position in the follow-up process, the object can be clearly displayed, and each object in the game picture can be clearly observed.

Step 304: determining whether the target object has a corresponding target center point and a corresponding target capturing gesture, if yes, executing step 312, and if not, executing

step

306 and 310.

It should be noted that, if the selected target object has been selected before, the observation position to which the observation camera is added and the shooting posture of the observation camera should have been determined before for the target object, so that the stored observation position (central point) and shooting posture can be directly obtained, i.e. step 312 is directly performed, and the operation step related to determining the envelope box of the target object to determine the observation position (i.e. step 306 and 310) does not need to be performed any more. Therefore, aiming at the same target object, the observation position of the observation camera and the shooting posture of the observation camera are not required to be repeatedly determined, repeated useless operation is avoided, the efficiency of observing the target object is improved, and processing resources are saved.

Step 306: and determining an envelope box of the target object, and adjusting the central point of the envelope box along the body diagonal direction of the envelope box.

Step 308: and adding an observation camera to the target object at the adjusted central point, determining the shooting posture of the observation camera according to the target area of the target object, and storing the corresponding relation among the target object, the central point and the shooting posture.

In this specification, after the observation camera is added to the target object at the adjusted central point, the shooting posture of the observation camera can be determined according to the target area of the target object, so that the observation position and the observation angle at which the target object can be carefully observed are determined, and the target object can be clearly displayed.

Step 310: and controlling the observation camera to shoot the posture observation target object.

Step 312: directly acquiring a target central point and a target shooting gesture corresponding to a target object, adding an observation camera for the target object at the target central point, and controlling the observation camera to observe the target object at the target shooting gesture.

For example, fig. 4 is a schematic diagram of a game screen provided in an embodiment of this specification, where the game screen includes objects "tree", "lamp", and "house", assuming that a selected target object is a "lamp", an envelope box of the "lamp" is determined, then a center point of the envelope box is adjusted along a diagonal direction of a body of the envelope box, an observation camera is added to the adjusted center point of the "lamp", and assuming that a determined shooting posture of the observation camera is minus 30 degrees, the observation camera is controlled to observe the "lamp" at the adjusted center point by minus 30 degrees, so as to obtain the game screen schematic diagram shown in fig. 5.
