The target object is an object to be subjected to force analysis, and the object to be analyzed may be a moving object or a stationary object, which may be determined according to an actual situation.
Illustratively, the mobile terminal takes a picture of an object to be analyzed from multiple angles to acquire an omnidirectional image of the object to be analyzed. The number of the shot pictures can be any number of pictures according to the fact that the shot images are subject to the acquisition of all characteristics of the object to be analyzed, and the invention is not limited herein.
And acquiring a 3D model generated according to the omnibearing image of the target object, and displaying the 3D model of the target object in an AR interface.
Exemplarily, the mobile terminal may acquire a 3D model of an object to be analyzed generated according to a photographed image, and load the 3D model on an opened AR interface, where the 3D model on the AR interface may have the same proportional size as the object to be analyzed, so that a user has a real viewing experience.
And 103, responding to the user operation aiming at the 3D model, and setting stress parameters aiming at the 3D model.
After the 3D model of the target object is displayed on the AR interface, the stress parameters of the 3D model are set in response to the operation of the user on the AR interface. In specific implementation, after a user can see the 3D model of the object to be analyzed on the AR interface, touch operation is performed on the 3D model, and the mobile terminal sets stress parameters of the 3D model in response to the touch operation of the user.
For example, a user may trigger to open an AR page in a mobile APP, an AR scene may be initialized when the page is opened, specifically, an AR view under a corresponding AR engine may be initialized, and a 3D model is loaded, and the user may set a stress parameter of the 3D model by touch on the AR interface.

After the user touches the AR interface to determine the stress state of the 3D model, clicking is started, and the AR interface demonstrates the track and the direction of the stress motion of the object to be analyzed.

Referring to fig. 2, a flowchart of steps of another AR-based physical analysis method provided in the embodiment of the present invention is shown, and is applied to a terminal device, where the method specifically includes the following steps:
Specifically, the mobile terminal carries out all-dimensional shooting on the object to be analyzed, the shot image is sent to the server, and the server can generate a 3D model with the same proportion size as the object to be analyzed according to the shot image and stores the 3D model as a URL link.
Illustratively, after the server acquires a picture shot in all directions, a 3D object is created by using an API interface newly provided by the MacOS system according to the acquired picture. Creating the 3D object includes: creating a photogrammetry session, wherein a URL with the required level of detail to point to the output location and model required for the generated USDZ format file is created first, and then using the request and the URL to point to the directory containing the image to create the object; creating a session of the 3D object, monitoring and providing state update related to the object creation process in the background by using the RealityKit, calling a process (requests:) for starting the session after receiving the state update, processing pictures in the background by using the RealityKit, generating a 3D model for shooting the object, and notifying when the processing is completed or fails. The completed process generates a 3D model of the subject, stored as a URL link.

In a specific implementation, the server may return the generated URL link to the user, and the user downloads and stores the 3D model locally through the URL link, opens an AR page in the application program of the mobile terminal, and loads the 3D model file stored locally.
And 204, acquiring the motion state of the target object determined according to the image.
For example, a motion state detection model may be utilized to perform static and dynamic object determination on an object in a captured picture to determine a motion state of the object to be analyzed.
And step 205, adding a corresponding rigid body to the 3D model according to the motion state of the target object.
In a specific implementation, a corresponding rigid body may be added to the 3D model according to the motion state of the object to be analyzed, giving the model physical properties. The rigid bodies can be divided into static rigid bodies and dynamic rigid bodies, the static rigid bodies do not move along with the change of external force, and the dynamic rigid bodies move along with the model according to the stress condition. If the object to be analyzed is in a static state, adding a static rigid body to the 3D model; and if the object to be analyzed is in a motion state, adding a dynamic rigid body to the 3D model.
For example, the user may perform a touch input operation on the AR page, add a rigid body to the 3D model, and generate a corresponding collision boundary. The collision boundary may be the size of the original model, or the size of the boundary may be adjusted by a user through manual drag control, which may be determined according to the actual situation, and the embodiment of the present invention is not limited to this.
In response to a user operation on a 3D model of an object to be analyzed, the magnitude and direction of a force are added to the 3D model, and a force type parameter is set. In a specific implementation, as shown in fig. 3, a schematic diagram of setting of stress parameters of an AR interface according to an embodiment of the present invention is shown, where a circle in the diagram is a 3D model, a square outside the circle is a physical rigid body of the 3D model, a user can see the 3D model of an object to be analyzed on the AR interface, then perform a touch operation on the 3D model, and a mobile terminal sets the stress parameters of the 3D model in response to the touch operation of the user.
In the embodiment of the present invention, the method may further include: setting a stress type in response to an operation of setting the stress type for the 3D model; setting the stress size in response to an operation of setting the stress size for the 3D model; and setting the stress direction in response to the operation of setting the stress direction for the 3D model.
Exemplarily, as shown in fig. 4, a schematic diagram of an option bar of a kind of an AR interface force according to an embodiment of the present invention is shown, where a circle in the diagram is a 3D model, a square outside the circle is a physical rigid body of the 3D model, and an AR interface where the 3D model is located may include an option bar providing a kind of a force, and when a user operates as a click or input operation on the option bar, the kind and magnitude of the force are determined; when the user operation is a sliding operation on the 3D model, the stress direction of the 3D model is determined.
For example, the option bar of the AR interface may include gravity, pressure, electric field force, magnetic field force, and the like, and the user may click the option bar to select the type of force according to the actual situation, and touch input determines the magnitude of the force, and may select the 3D model by clicking the 3D model. And controlling the stress direction of the 3D model according to the gesture operation of sliding the screen by the user.
It should be understood by those skilled in the art that the above-described user operation manner is merely an example of the present invention, and those skilled in the art may set the user operation manner by using other user operation methods, and the embodiment of the present invention is not limited herein.
In the embodiment of the present invention, the method may further include: and adding and displaying corresponding interface elements in the 3D model according to the stress parameters of the 3D model.
In order to distinguish the type, the size and the direction of the stress of the object to be analyzed, corresponding interface elements are added to the 3D according to specific stress parameters of the 3D model and are displayed on an AR interface. For example, the user adds the set force to the 3D model through a model composed of dotted lines, sets parameters such as damping coefficients, and simulates the object motion and collision effect.
As an example, the interface elements corresponding to different kinds of forces are different, the different interface elements may be arrows with different shapes or colors, or straight lines, or curved lines, or a combination thereof, and the user may select the different interface elements to represent that the 3D model is subjected to different types of forces, for example, the user may select blue arrows to represent the gravity of the 3D model and red arrows to represent the pressure of the 3D model.
For example, in the physical teaching, when the force of the moving charge in the magnetic field needs to be analyzed, a user can click an interface element corresponding to the magnetic field in an option bar of the AR interface, add a blue magnetic field to the 3D model of the moving charge, and set the magnetic field strength and direction; clicking an interface element corresponding to gravity, adding red gravity to the 3D model of the motion charge, touch-controlling the input gravity and the motion charge speed, clicking and sliding the 3D model, giving the 3D model a speed direction, and further simulating the motion track of the motion charge in a magnetic field, and more intuitively analyzing the stress condition of the motion charge in the magnetic field, thereby facilitating better learning and understanding of students.
It should be understood by those skilled in the art that the form of the interface element described above is merely an example of the present invention, and those skilled in the art may set other forms of interface elements, which may be determined according to practical situations, and the embodiment of the present invention is not limited to this.
And step 207, when the AR interface displays the 3D models corresponding to the target objects, controlling the 3D models to move according to the stress parameters of the 3D models.
After the stress parameters of the 3D model are set, the mobile terminal can control the 3D model to simulate the motion state of the target object according to the stress parameters, and the motion trail of the target object is displayed on the AR interface.
In the embodiment of the invention, the AR interface can display the 3D models of the target objects, the mobile terminal can control the 3D models to move according to the stress parameters of the 3D models, and the interactive pictures of the 3D models are displayed on the AR interface.
For example, in physical teaching, when stress conditions and motion conditions of two objects colliding with each other need to be displayed, firstly, the colliding object and the collided object are shot in a multi-angle and all-around mode, shot images are uploaded to a server, the server generates 3D models of the colliding object and the collided object according to the images, after the 3D models of the colliding object and the collided object are loaded on an AR interface, stress parameters are set for the 3D model of the colliding object and the 3D model of the collided object respectively, interface elements are added, and then stress conditions and motion tracks of the 3D model of the colliding object and the 3D model of the collided object are displayed on the AR interface.
In addition, the 3D model of the object to be analyzed can also simulate the condition of external force increase, for example, the 3D model of the stressed object to be analyzed can be used for simulating the condition of external force increase, and then the scene when the object to be analyzed collides is received, the image of another object can be shot in all directions again, the 3D model of another object is generated, the 3D model of the object to be analyzed and the 3D model of the object to be analyzed are displayed on the same AR interface, the stress parameter of the 3D model of the other object is set, new acting force is added to the 3D model of the object to be analyzed, and then the process that the motion trail of the object to be analyzed changes after the new added force and the process of interaction with the 3D model of the other object can be displayed on the AR interface.
It should be understood by those skilled in the art that the above-mentioned manner of representing the motion trajectories of the plurality of 3D models is only an example of the present invention, and those skilled in the art may use other representation methods to represent the motion trajectories, and the present invention is not limited herein.
