At present, the AR technology has few application scenes in a multi-player shooting game, for example, a spaceship battle game participated by multiple players, each user can control a matched virtual spaceship through a carried AR device, and in a similar application scene, how to enable the game to have a more vivid effect through the AR technology is a technical problem to be discussed in the disclosure.
Based on the research, the present disclosure provides a method for displaying a shooting trajectory, which can determine trajectory information of a bullet fired by a virtual aircraft by acquiring pose data of each AR device in a target real scene in real time, and pose control data and bullet firing control data of the AR device for the matched virtual aircraft, and further generate fused trajectory display data for at least one bullet of the AR device for each AR device according to the pose data of the AR device and the trajectory information of the bullet fired by each virtual aircraft, that is, multiple users can respectively see the trajectory of the bullet fired by the virtual aircraft through the respective AR devices, so that the AR technology can be applied to the field of multiplayer games, and users at different positions can see the trajectory of the bullet from different viewing angles, thereby making the display more realistic.
To facilitate understanding of the present embodiment, a detailed description is first given of a method for displaying a shooting track disclosed in the embodiments of the present disclosure, and an execution subject of the method for displaying a shooting track provided in the embodiments of the present disclosure is generally a computer device with certain computing power, where the computer device includes, for example, a server or other processing devices. In some possible implementations, the method for presenting a shot trajectory may be implemented by a processor calling computer-readable instructions stored in a memory.
Referring to fig. 1, a flowchart of a method for displaying a shooting trajectory according to an embodiment of the present disclosure is shown, where the method includes the following steps S101 to S103:
s101, acquiring pose data of each AR device in the associated AR device group in a target real scene in real time, and pose control data and bullet shooting control data of each AR device for the matched virtual aircraft.
For example, each AR device in the associated AR device group may commonly experience the same AR scene content, and in an application scene, the AR devices may select the same AR experience package to enter a multi-player interactive AR scene, for example, for an AR scene of a game class, each AR device may enter the same AR room to experience the AR scene by logging in an AR game account, so that the AR devices entering the same AR room may serve as the associated AR device group.
For example, the pose data of the AR device in the target reality scene may include a position and/or a display angle of a display component for displaying the virtual operation object when the user holds or wears the AR device.
The display component of the AR device specifically refers to a component used for displaying a virtual operation object in the AR device, for example, when the AR device is a mobile phone or a tablet, the corresponding display component may be a display screen, and when the AR device is AR glasses, the corresponding display component may be a lens used for displaying a virtual aircraft.
For example, the embodiment of the present disclosure may determine the pose data of each AR device through a real scene image of the AR device taken for a target real scene, which will be explained later.
For example, the virtual operation object matched with each AR device may be a virtual aircraft to be controlled and selected after the AR device logs in an AR account, for example, an AR scene is an airship battle scene, where each AR device may select a virtual battle airship to be controlled and select a number of the matched virtual battle airship after logging in the AR account, so that the AR device may send pose control data and bullet launching control data for the virtual battle airship with the matched number to a server during an AR experience.
The pose control data may comprise position control data and/or attitude control data for the virtual aircraft, wherein the position control data may determine a target position to which the virtual aircraft is flying, and the attitude control data may determine a flight attitude of the virtual aircraft.
Illustratively, the bullet firing control data includes, but is not limited to, one or more of the following:
data indicating whether the virtual aircraft fired the bullet, data of the type of bullet fired, and corresponding shot force data when the bullet was fired.
And S102, determining track information of bullets launched by each virtual aircraft based on the pose control data for the virtual aircraft and the bullet launching control data for the virtual aircraft.
For each virtual aircraft, the pose data of the virtual aircraft can be determined based on the pose control data for the virtual aircraft, and then based on the bullet firing control data for the aircraft, whether the virtual aircraft has fired a bullet, the type of fired bullet, the firing power, and the like can be determined.
By combining the pose data of the virtual aircraft and the related data of the bullets launched by the virtual aircraft, the bullet launched by the virtual aircraft at which pose, the type and shooting strength of the launched bullet can be determined, so that the track information of the bullet launched by the virtual aircraft can be determined.
Illustratively, if any virtual aircraft launches a bullet with a range of 1 meter to the east, the trajectory information of the bullet launched by any virtual aircraft can be 1 meter of the bullet flown to the east by the virtual aircraft, and of course, in order to make the display effect more realistic, the influence of gravity on the bullet can be considered here, so that the trajectory of the bullet appears to be parabolic.
S103, generating fusion track display data of at least one bullet aiming at each AR device according to the pose data of the AR device and the track information of the bullets launched by each virtual aircraft and sending the fusion track display data to the AR device for display.
The pose data of each AR device in the target real scene are different, so that the viewing fields of view of the target real scene through the AR devices are different, and the presentation special effects of the track of the bullet viewed by each user through the respective AR devices are possibly different.
Illustratively, the associated AR device group may include a first AR device and a second AR device, which are respectively carried by the user a and the user B, and when the user a and the user B can see the same bullet through the respective carried AR devices, for example, see the bullet launched by the virtual aircraft 001, the difference is that when the pose data of the first AR device and the second AR device are different, the viewing angles of the bullet launched by the virtual aircraft 001 seen by the user a and the user B are different, for example, the user a sees the right side of the bullet itself flying, and the user B sees the left side of the bullet itself flying.
In the embodiment of the disclosure, fusion trajectory display data for at least one bullet of the AR device can be generated according to the pose data of the AR device and the trajectory information of the bullets launched by each virtual aircraft, that is, a plurality of users can respectively see the trajectory of the bullets launched by the virtual aircraft through the respective AR devices carried by the users, so that the application of the AR technology in the field of multiplayer games can be realized, and the trajectory of the bullets can be seen from different viewing angles by the users at different positions, thereby enabling the display content to be more vivid.
The above-mentioned S101 to S103 will be explained with reference to specific embodiments.
For the above S101, when acquiring pose data of each AR device in the associated AR device group in the target real scene in real time, as shown in fig. 2, the following S1011 to S1012 are specifically included:
s1011, real scene images shot by each AR device in the associated AR device group aiming at the target real scene are obtained in real time;
and S1012, determining the pose data of the AR equipment in the target real scene based on the real scene image shot by each AR equipment and a pre-established three-dimensional scene model for representing the target real scene.
For example, the three-dimensional scene model may be constructed based on a plurality of sample images of the target real scene captured in advance, specifically, during construction, the three-dimensional scene model may be constructed by extracting feature points in each sample image, after the three-dimensional scene model is generated, the sample image corresponding to each feature point in the three-dimensional scene model may be saved, and the capturing pose of the sample image in the three-dimensional scene model may be stored, so that after the real scene image of the target real scene captured by the AR device is obtained, the feature points may be extracted from the real scene image, the sample image matched with the real scene image is determined based on the extracted feature points, and finally, the pose data of the AR device in the three-dimensional scene model is obtained.
Because the three-dimensional scene model is a model representing the target real scene, the pose data of the AR device in the three-dimensional scene model can be used as the pose data of the AR device in the target real scene.
In addition, the pose data of the AR device may also be determined by a pose sensor mounted to the AR device.
Or, in another embodiment, the real scene image shot by the AR device may be further input into a neural network model for positioning stored in advance, so as to determine the pose data corresponding to the AR device shooting the real scene image.
Specifically, the neural network may be trained based on a plurality of sample images obtained by shooting a real scene in advance, and pose data corresponding to each sample image.
The three-dimensional scene model can be constructed based on a plurality of real scene images shot for the target real scene in advance, and after the construction is completed, the constructed three-dimensional scene model can be corrected through a real two-dimensional map corresponding to the target real scene, so that the three-dimensional scene model representing the target real scene with high accuracy is obtained.
Regarding the above S102, when determining trajectory information of a bullet fired by each virtual aircraft based on the pose control data for the virtual aircraft and the bullet firing control data for the virtual aircraft, as shown in fig. 3, the following S1021 to S1023 may be included:
s1021, determining pose data of each virtual aircraft based on the pose control data for the virtual aircraft;
s1022, determining the initial position, the shooting direction and the shooting strength of the virtual aircraft for shooting the bullet based on the pose data of the virtual aircraft and the bullet shooting control data aiming at the virtual aircraft;
and S1023, determining the track information of the bullets launched by the virtual aircraft based on the initial position, the launching direction and the shooting strength of the bullets launched by the virtual aircraft.
Exemplarily, the initial position of the bullet launched by the virtual aircraft is the position a in the target reality scene, the launching direction is the direction toward the east in the target reality scene, the shooting strength is the selected preset three-level strength, and can be the maximum strength corresponding to the virtual aircraft, then the parabolic shape of the bullet launched by the virtual aircraft can be determined according to the shooting strength and the gravity, and the trajectory information of the bullet launched by the virtual aircraft in the target reality scene can be determined by combining the initial position and the launching direction.
In the embodiment of the disclosure, the trajectory information of the bullet launched by the virtual aircraft in the target real scene can be determined by combining the pose data of the virtual aircraft and the bullet launching control data of the virtual aircraft, so that the trajectory of the bullet launched by the virtual aircraft in the AR scene can be conveniently and intuitively displayed to a user, and the displayed content is more vivid.
For the above S103, when generating, for each AR device, fused trajectory presentation data of at least one bullet for the AR device based on the pose data of the AR device and trajectory information of bullets fired by the respective virtual aircraft, as shown in fig. 4, the following S1031 to S1032 may be included:
s1031, determining fusion track special effect data of at least one bullet based on track information of bullets launched by each virtual aircraft;
s1032, for each AR device, determining fused track showing data of at least one bullet for the AR device based on the pose data of the AR device and the fused track special effect data corresponding to the at least one bullet.
In an application scenario, there may be a scenario where a plurality of virtual aircraft simultaneously fire bullets, where trajectory information of bullets fired by each virtual aircraft in the same time period may be fused based on trajectory information of bullets fired by each virtual aircraft to obtain fused trajectory special effect data of at least one bullet, for example, trajectory information of bullets respectively fired by two virtual aircraft may be simultaneously included, where trajectory information of one bullet is a trajectory fired from an a position to the east, and trajectory information of another bullet is a trajectory fired from a B position to the west, and trajectory information of the two bullets is fused, that is, the fused trajectory special effect data includes trajectory information of the two bullets.
In an implementation manner, as shown in fig. 5, the display method provided in the embodiment of the present disclosure further includes the following steps S501 to S503:
s501, it is determined whether there is at least one target virtually fired bullet hit based on the pose control data for each virtual aircraft and the bullet firing control data for the virtual aircraft.
Specifically, when determining whether there is at least one target virtually fired bullet hit based on the pose control data for each virtual aircraft and the bullet firing control data for the virtual aircraft, it may include:
(1) determining a moving track of each virtual aircraft within a preset time length based on the current pose data of the virtual aircraft and pose control data aiming at the virtual aircraft within the preset time length;
(2) determining whether the moving track of the target virtual aircraft intersects with the flight track of any bullet or not based on the track information of each bullet in the preset time length and the moving track of each virtual aircraft in the preset time length;
(3) upon determining that there is an intersection of the trajectory of movement of the target virtual aircraft with the flight trajectory of any of the bullets, determining that there is at least one target virtual aircraft that was hit by a bullet.
For example, a time period required for the bullet to fall from the shooting may be set to a preset time period here, and within the preset time period, the movement trajectory of each virtual aircraft may be determined based on the current pose data of the virtual aircraft and the pose control data for the virtual aircraft.
In addition, the position of the target virtual aircraft shot by any bullet can be determined according to the corresponding intersection point position of the target virtual aircraft when intersecting with the flight track of the bullet, such as the head, the tail or the middle of the target virtual aircraft can be shot.
S502, when it is determined that at least one target virtual aircraft is shot by a bullet, determining special effect data when the at least one target virtual aircraft is shot by the bullet.
Illustratively, the special effect data may include position data in setting by a bullet, explosion data, and the like.
S503, aiming at each AR device, generating fusion shooting display data aiming at the AR device based on the pose data of the AR device and the special effect data of at least one target virtual aircraft when being hit by a bullet, and sending the fusion shooting display data to the AR device for displaying.
Likewise, because each AR device has different pose data in the target real scene, and thus the viewing field of view for the target real scene by the AR device is also different, and the target virtual aircraft viewed by each user through the respective AR device may also have different special effects when being shot by a bullet, it is necessary to generate, for each AR device, fused shot presentation data for the AR device based on the pose data of the AR device and the special effect data of at least one target virtual aircraft when being shot by a bullet.
Illustratively, the user on the AR device side can view the presentation picture of the target virtual aircraft shot in the own viewing field of view through the fused shooting demonstration data aiming at the AR device.
In a possible implementation manner, the display method provided by the embodiment of the present disclosure further includes:
(1) in response to the fact that the target virtual aircraft is hit by the bullet, updating the pose data of the target virtual aircraft to obtain new pose data corresponding to the target virtual aircraft;
(2) and generating pose change display data of the target virtual aircraft for the AR equipment based on the pose data of the AR equipment and the new pose data corresponding to the target virtual aircraft for each AR equipment, and sending the pose change display data to the AR equipment for display.
Specifically, new pose data corresponding to the target virtual aircraft can be determined based on the shot position of the target virtual aircraft and the shot strength, and the new pose data can be used for representing the position change and/or the posture change of the target virtual aircraft after the target virtual aircraft is shot.
Further, similarly, because the pose data of each AR device in the target real scene are different, the viewing fields of view of the target real scene by the AR devices are also different, and the pose change display data of the target virtual aircraft viewed by each user through the respective AR device after being ejected by a quilt is also different, so that the pose change display data for each AR device needs to be generated based on the pose data of the AR device and the new pose data of the target virtual aircraft after being ejected by the quilt.
Illustratively, the user on the AR device side can view a presentation picture of the pose change of the target virtual aircraft after being shot in the viewing field of the user through the pose change presentation data for the AR device.
