Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings, not all of them.
Example one
Fig. 1 is a flowchart of a method for determining a photographic object according to an embodiment of the present invention, where this embodiment is applicable to a case of determining a target photographic object in a multimedia resource, and is particularly applicable to a case of determining a target photographic object in a game screen, and the method may be executed by a device for determining a photographic object, where the device may be implemented by hardware and/or software, and the method specifically includes the following steps:
and S110, determining a first target object to be shot.
Wherein the first target object can be understood as a main reference object in the current game scene. The first target objects include, but are not limited to, player characters, game monsters, game Non-Player characters (NPCs), skill and scene buildings. It is noted that player-manipulated characters include, but are not limited to, characters and animals; scene buildings include, but are not limited to, natural landscapes such as mountains, sky and grasslands, and real buildings such as churches and fountains; the skill may be an active skill or a passive skill released by the player manipulating the character or game monster.
It should be noted that the current game scene may be a game scene displayed on the client of the target player. For example, the current game scene may be an interaction scene between a plurality of player-controlled characters, an interaction scene between a player-controlled character and an NPC, a battle scene between a player-controlled character and a BOSS, a battle scene between a plurality of player-controlled characters, or a scene in which a player-controlled character appreciates a scene building. In the current game scene, at least one other object may be included in addition to the first target object to be photographed, and therefore, it is necessary to determine the first target object to be photographed from the current game scene.
Specifically, the first target object to be photographed may be determined based on a scene type of a current game scene and/or attribute information of the object.
The scene type of the current game scene can be an interactive scene, a battle scene or a scenery scene. For example, interaction scenes among a plurality of player control characters and interaction scenes between the player control characters and the NPC are interaction scene types; the combat scenes between the player control role and the BOSS and between the plurality of player control roles are all of combat scene types; the player controls the character to enjoy the scene of the scene building as the scene.
Different scene types are provided with corresponding first target objects. For example, the first target object to be photographed corresponding to the interactive scene may be a player control character of a target player; the first target object to be shot corresponding to the battle scene can be a player control character of a target player or a game monster; the first target object to be photographed corresponding to the scene may be a player-operated character of the target player or a scene building. Specifically, the scene type of the current game scene is determined, and the first target object to be shot is determined based on the scene type.
For example, the battle scene can be further divided into scenes corresponding to various game copies, such as the ruins of the dragon, the gold houses and other copies, and the first target objects corresponding to different copies are different. Corresponding scene identifications can be distributed for the subdivided game scenes, and corresponding object identifications of the first target object are set for different scene identifications in advance. When a first target object to be shot of a current game scene needs to be determined, a scene identification of the current game scene is identified, a corresponding object identification is determined based on the scene identification of the current game scene, and an object conforming to the object identification is identified in the current game scene and serves as the first target object to be shot.
In another embodiment, a player manipulation character of a target player in a current game scene may be determined as a first target object to be photographed. And if the current game scene does not contain the player control role of the target player, determining the BOSS as a first target object to be shot. And if the current game scene does not contain the player control role and the BOSS of the target player, determining a first target object to be shot based on the attribute information of the other player control roles.
And S120, determining at least one second target object based on the first target object and a preset distance upper limit threshold.
The preset upper distance threshold may be understood as a maximum object distance between the second target object and the first target object. The application does not limit the specific value of the distance upper threshold. Specifically, an object whose distance from the first target object is less than or equal to a preset distance upper limit threshold is determined as the second target object. The second target object may be understood as a candidate object to be photographed close to the first target object. The number of the second target objects in this embodiment may be one or more.
In one embodiment, a sphere region may be determined with the first target object as a center and a preset distance upper threshold as a radius, and each object in the sphere region may be determined as the second target object. In another embodiment, an orientation marking line is established based on the orientation direction of the first target object, an angle range is determined based on the orientation marking line, a fan-shaped area with the vertex of the first target object is created in the angle range, and each object in the fan-shaped area is determined as the second target object.
It should be noted that the preset distance upper limit threshold corresponding to different first target objects may be different. The distance upper threshold may be determined based on attribute information of the first target object. Wherein, the attribute information includes but is not limited to attack attribute information and volume information, wherein the attack information includes but is not limited to general attack distance, active skill attack distance and passive skill trigger distance. Specifically, the distance upper threshold may be equal to any one of a general attack distance, an active skill attack distance, and a passive skill trigger distance of the first target object. Alternatively, the preset upper threshold of the distance corresponding to the first target object may be equal to any one of the three distances plus a preset distance adjustment value.
Alternatively, the distance upper threshold may be determined based on volume information of the first target object. The larger the volume of the first target object, the larger the distance upper threshold. For example, the volume of the BOSS is usually much larger than that of the player-operated character, and the distance upper threshold corresponding to the BOSS should be much larger than that corresponding to the player-operated character.
In another embodiment, the distance upper threshold may also be determined based on the scene type of the current game scene.
Optionally, determining at least one second target object based on the first target object and a preset distance upper threshold, including: calculating an object distance between the first target object and at least one target object to be selected; and if the object distance is less than or equal to the preset distance upper limit threshold, determining the target object to be selected as a second target object.
The target object to be selected may be each object except the first target object in the current game scene. Specifically, an object distance between each candidate target object and the first target object is calculated, and the second target object is determined based on the object distance of each candidate target object. The object distance may be understood as a euclidean distance between each candidate target object and the first target object, i.e., a straight-line distance. Alternatively, the object distance may be determined based on the collision box, the root node, or the feature point of each object and the first target object.
Specifically, collision boxes of a first target object and other objects than the first target object are acquired, respectively, and object distances of the first target object and the other objects are calculated based on position information of the collision boxes. Or, root nodes or feature points of the first target object and other objects except the first target object are respectively acquired, and the object distance between the first target object and the other objects is calculated based on the position information of the root nodes or the feature points. The root node can be understood as a key node on the subject body, such as a hand, a foot, and the like; the feature point may be a point on the subject's body that is closest or farthest to the first target subject, or a center of gravity, center, or centroid of the subject, or the like.
In these alternative embodiments, the object distance between the first target object and the at least one candidate target object is calculated; and if the object distance is less than or equal to the preset distance upper limit threshold, determining the target object to be selected as a second target object so as to determine the second target object based on the object distance, thereby accurately determining the second target object.
And S130, determining a target shooting object based on the first target object and at least one second target object.
The target shooting object can be understood as a key object in the current game scene, namely an object to be shot. The number of target photographic subjects may be one or more.
In one embodiment, the number of the target photographic objects is plural, the first target object may be determined as the target photographic object, and the target photographic object may be determined based on at least one of attribute information of the second target object, orientation information of the first target object and the second target object, and a scene type of a current game scene.
The attribute information includes, but is not limited to, type information, volume information, blood volume information, rareness information, and grade information. The type information indicates a type corresponding to the second target object, for example, a player character, a parietal monster, a BOSS, an NPC, a building, and the like. The rarity information may be rarity of the second target object, such as rarity of BOSS, rarity of a player-operated character, rarity of NPC, rarity of a scene building, or the like, and may also be rarity of weapons or equipment worn by the second target object. The level information may be a level corresponding to the second target object, such as a level of a player manipulating a character or a level of BOSS, and the level information may also be a level corresponding to a weapon or equipment worn by the second target object.
Specifically, the second target object of the player character type or the BOSS type may be determined as the target photographic object. Or, a second target object satisfying at least one of the attributes of the largest volume, the largest blood volume, the highest rareness degree, and the highest rank is determined as the target photographic object.
The orientation information may be orientation direction information of a target portion of the first target object or the second target object, for characterizing an overall orientation direction of the object. The target part may be a part such as a hand, a foot, a back, or a face. The corresponding orientation angles may be determined based on the orientation information, resulting in orientation angles of the target portions of the first and second target objects, the overall orientation direction of the object being characterized by the orientation angles. Specifically, the orientation angle difference is determined based on the orientation angles of the first target object and each second target object, and the second target object with the orientation angle difference smaller than a preset angle difference threshold value is determined as the target shooting object.
According to the technical scheme of the embodiment, a first target object to be shot is determined; determining at least one second target object based on the first target object and a preset distance upper limit threshold; the target photographic object is determined based on the first target object and at least one second target object. According to the technical scheme of the embodiment of the invention, the first target object is determined, the second target object is further determined based on the first target object and the preset distance upper limit threshold, and the target shooting object is determined based on the first target object and the second target object, so that the determination of the key object of the game scene is realized, and the problem that the key object in the game scene cannot be shot in the prior art is solved.

S220, determining at least one second target object based on the first target object and a preset distance upper limit threshold.
And S230, determining volume information of the at least one second target object, and determining at least one third target object based on the volume information.
Wherein the volume information may be determined based on a volume size of a collision box or bounding box of the second target object. In particular, a second target object exceeding a preset volume threshold may be determined as a third target object. The preset volume threshold may be determined according to attribute information of the first target object or a scene type of a current game scene, which is not limited in this application. The number of the third target objects in this embodiment may be one or more.
In a game scene, the BOSS in a battle scene and the scene building in a scenery scene are both large in volume. For example, the current game scenario is that a player-controlled character is about to fight a BOSS, a plurality of corner monsters are beside the BOSS, the volume of the BOSS is much larger than that of each corner monster, and if the first target object is the player-controlled character, the second target object is the BOSS and each corner monster, the third target object is the BOSS.
In another embodiment, the second target objects may be sorted based on the volume information of the second target objects, an ordered list with gradually decreasing volume size is generated, the first second target object in the list is determined as the third target object, or the top N second target objects in the list are determined as the third target object. For example, the number of the BOSSs in the battle scene is multiple, and the size of the volume differs little, each BOSSs may be a third target object.
And S240, determining a target shooting object based on the first target object and the third target object.
Specifically, the target photographic object may include the first target object and all the third target objects; the first target object and a part of the third target object may also be included, and the target photographic object is determined based on the orientation information of the first target object and the third target object, for example. And determining a third target object with the orientation angle difference smaller than a preset angle difference threshold value as a target shooting object.

Wherein explanations of the same or corresponding terms as those of the above embodiments are omitted.
Referring to fig. 3, the method for determining a photographic subject according to the present embodiment includes the following steps:
and S310, determining a first target object to be shot.
S320, determining at least one second target object based on the first target object and a preset distance upper limit threshold.
And S330, determining the first target object and a second target object closest to the first target object as target shooting objects.
Wherein, the distance between the second target object and the first target object may be the distance between the root nodes or feature points of the first target object and the second target object, and the root nodes may be key nodes such as hands, feet, etc.; the feature point may be a point on the subject's body that is closest or farthest to another subject, or the subject's center of gravity, center, or centroid, etc. In one embodiment, the distance between the first target object and the second target object may be a distance between a point on the body of the first target object closest to the second target object and a point on the body of the second target object closest to the first target object.
Specifically, the distance between the first target object and each second target object is determined, and the second target object closest to the first target object and the first target object are determined as target shooting objects. For example, in the current game scenario, a player-controlled character is about to fight against the BOSS, and a plurality of corner monsters are further arranged behind the BOSS, in this case, if the first target object is the player-controlled character, the second target object is the BOSS and the corner monsters, the second target object closest to the player-controlled character is the BOSS, and the target shooting objects are the player-controlled character and the BOSS.
According to the technical scheme, the first target object and the second target object which is closest to the first target object are determined as the target shooting objects, so that the target shooting objects are accurately determined, and the accuracy of the target shooting objects is improved.
Example four

Wherein explanations of the same or corresponding terms as those of the above embodiments are omitted.
Referring to fig. 4, the method for determining a photographic subject according to the present embodiment includes the following steps:
and S410, determining a first target object to be shot.
And S420, determining at least one second target object based on the first target object and a preset distance upper limit threshold.

The motion information includes, but is not limited to, a moving distance, a moving speed, a moving direction, and an instantaneous acceleration of the second target object within a set time. The moving speed refers to an average moving speed of the second target object within a set time. In the present embodiment, the at least one third target object may be determined based on at least one of a moving distance, a moving speed, a moving direction, and an instantaneous acceleration of the second target object.
Optionally, determining a second target object with the largest moving distance, moving speed or instantaneous acceleration within a set time as a third target object; and/or determining a second target object with the moving direction facing to the first target object as a third target object. For example, in the current game scenario, each player-controlled character fights with the BOSS, the first target object is the BOSS, each player-controlled character may rush to the BOSS when releasing skills, and at this time, the player-controlled character with the largest moving distance, moving speed or instantaneous acceleration may be determined as the third target object, and/or the player-controlled character with the moving direction toward the BOSS may be determined as the third target object.
Optionally, determining at least one third target object based on the motion information includes: at least one third target object is determined based on the amount of change in the motion information.

Specifically, the second target object whose movement speed or movement distance has the largest variation is determined as the third target object. Or, determining a second target object of which the variation of the moving speed is greater than a preset speed variation threshold or the variation of the moving distance is greater than a preset distance variation threshold as a third target object. The specific numerical values of the preset speed change threshold and the preset distance change threshold are not limited in the application.
For example, when each player control character fights the BOSS in the current game scenario, the first target object is the BOSS, and when each player control character attacks the BOSS, some player control characters may instantaneously move to the vicinity of the position of the BOSS through the skill after the cooling time of the skill is over, and at this time, although the variation of the movement speed of the some player control characters may be small, the variation of the movement distance is large, and the player control character with the large variation of the movement distance may be determined as the third target object. Alternatively, in the process of preparing to release the move skill or release the move, some of the player characters may accelerate toward the BOSS, and at this time, the variation of the moving speed of the some of the player characters is large, and the player character with the large variation of the moving speed may be determined as the third target object.
In these alternative embodiments, the determination of the at least one third target object based on the variation amount of the motion information enables accurate determination of the third target object, and further, enables accurate determination of the target photographic object.

The position information of the second target object may be position information of the second target object in the current game scene, and may be understood as coordinates of the second target object in the current game scene. Specifically, the sitting position information of the second target object in the current game scene may be determined based on the root node or the feature point of the second target object. For example, the coordinates corresponding to the head of the second target object are determined as the coordinates of the second target object, so as to obtain the position information of the second target object.
In one embodiment, the coordinates of the second target object in the current game scene may be determined based on the three-dimensional space coordinate axis by establishing the three-dimensional space coordinate axis based on the display range of the current game scene.

The preset area may be an area preset in the current game scene, such as: a cylinder region centered at the BOSS; or a sector area with the scene building as a vertex. The size and shape of the preset area can be adjusted according to actual requirements. The preset position may be understood as a preset coordinate, such as a certain coordinate in the vicinity of the NPC. Specifically, the position information of at least one second target object is determined, and the second target object located in the preset area or at the preset position is determined as a third target object.
The position information of the second target object may be a relative position between the second target object and the first target object, including but not limited to a relative distance and/or a relative angle to the first target object. Specifically, the position information of at least one second target object is determined, and the second target object whose relative distance is within a preset distance range or whose relative angle satisfies a preset angle range is determined as a third target object. It should be noted that the preset distance range and the preset angle range can be adjusted according to actual requirements, and the specific numerical values of the preset distance range and the preset angle range are not limited in the present application.
