[0050] As shown in Figure 1 An image preview method according to an embodiment of the present application includes the following steps:

[0051] Step 101, performing three-dimensional processing on a target image received in the process of video call to obtain a three-dimensional model corresponding to the target image;

[0052] Step 102, displaying the three-dimensional model in a first three-dimensional space; the first three-dimensional space is composed of images in a first scene collected by a terminal camera at a first time, and the first time is the time when the target image is received;

[0053] Step 103, displaying prompt information on the interface of the video call, the prompt information being used to indicate a first operation for viewing the target image;

[0054] Step 104: When the first operation is detected, the display interface of the terminal is switched to the target image displayed in a second three-dimensional space; the second three-dimensional space is composed of images of the first scene captured by the terminal camera at a second moment, and the second moment is the moment when the first operation is received.

[0055] Optionally, receiving the target image includes one of the following:

[0056] The target image received via an instant messaging application;

[0057] the target image received via SMS;

[0058] the target image received via Bluetooth;

[0059] By transmitting the received target image.

[0060] Optionally, the camera is a rear camera of the terminal;

[0061] The first scene is the environment scene where the user is currently located.

[0062] like Figure 2 As shown, when a target image is received during a video call, a thumbnail B of the target image is displayed on the interface A of the video call;

[0063] like Figure 3 As shown, in the video call interface, the prompt information is displayed near the thumbnail of the target image, and the prompt information displays the user operation required to view the target image.

[0064] The image preview method of the embodiment of the present invention can place the target image in the three-dimensional model by performing three-dimensional processing on the target image received during the video call; can display the virtual target image in a real three-dimensional scene by displaying the three-dimensional model in the first three-dimensional space; can enable the user to view the target image according to the prompt information by displaying the prompt information; and can switch the display interface to the target image displayed in the second three-dimensional space according to the first operation trigger, so that the target image can be displayed in the real second three-dimensional space, thereby establishing a corresponding relationship between the target image and the first scene, and the viewing operation of the target image is simple, thereby improving the user's immersive viewing experience of the target image.

[0065] Optionally, performing three-dimensional processing on a target image received during a video call to obtain a three-dimensional model corresponding to the target image includes:

[0066] acquire a photo frame three-dimensional model;

[0067] replace an image area in the photo frame three-dimensional model with the target image to obtain the three-dimensional model;

[0068] The image area is a texture picture in the photo frame three-dimensional model.

[0069] Optionally, the photo frame three-dimensional model is a pre-prepared model saved in the terminal.

[0070] As shown in Figure 4 the image area in the photo frame three-dimensional model is a separate texture picture, and the texture picture in the photo frame three-dimensional model D is replaced with the target image F to obtain the three-dimensional model.

[0071] The image preview method in the embodiment of the present application, through the three-dimensional processing of the target image, superimposes the target image in the photo frame three-dimensional model to obtain the three-dimensional model; and displays the target image in the first three-dimensional space through the three-dimensional model, that is, places the virtual three-dimensional model in the real three-dimensional space (the first scene), and improves the experience of the user in immersive viewing of the target image.

[0072] Optionally, displaying the three-dimensional model in the first three-dimensional space comprises:

[0073] constructing a coordinate system according to the position of the terminal at the first time point;

[0074] in the case that there is a plane in the image in the first three-dimensional space, displaying the three-dimensional model by fitting the plane;

[0075] in the case that there is no plane in the image in the first three-dimensional space, displaying the three-dimensional model according to the coordinate system at a preset spatial position.

[0076] In the embodiment of the present application, the scene corresponding to the first three-dimensional space is indoor, and there are many planes (such as tables, chairs, cabinets, and walls) in the image in the first three-dimensional space, and at this time, the three-dimensional model can be displayed by fitting on a selected one of the planes.

[0077] In the embodiment of the present application, the scene corresponding to the first three-dimensional space is outdoor, and the environment in the first three-dimensional space is relatively complex, and it is possible that no plane can be detected, and at this time, the three-dimensional model is displayed according to the coordinate system at a preset spatial position.

[0078] The image preview method of the embodiment of the present application can save the target image in a real three-dimensional scene (the first three-dimensional space) by displaying the target image in the first three-dimensional space, thereby improving the user's immersive viewing experience of the target image.

[0079] like Figure 5 As shown, constructing a coordinate system based on the position of the terminal at the first moment includes:

[0080] Establishing the coordinate system with the position of the terminal at the first moment as the origin, the first direction as the X-axis, the second direction as the Y-axis, and the third direction as the Z-axis;

[0081] The first direction is a direction perpendicular to the left and right frames of the terminal, the second direction is a direction perpendicular to the upper and lower frames of the terminal, and the third direction is a direction perpendicular to the terminal display screen.

[0082] In the embodiment of the present application, the preset spatial position is 45 degrees to the left of the Z axis in the coordinate system and is 0.5 m away from the terminal.

[0083] In the embodiment of the present application, the position of the terminal refers to the position of the center of gravity of the terminal, or the position of the terminal refers to the position of the center of the camera module of the terminal; it depends on the specific needs or the shape design of the terminal.

[0084] The image preview method of the embodiment of the present application establishes the coordinate system through the position of the terminal at the first moment, thereby being able to determine whether the terminal has moved or rotated, and providing a position and posture comparison standard for detecting the first operation.

[0085] Optionally, when the first operation is detected, switching the display interface of the terminal to the target image displayed in the second three-dimensional space includes:

[0086] When it is detected, based on the real-time acquired position information of the terminal, that an angular deviation between the terminal and a first coordinate axis of the coordinate system is greater than or equal to a preset angle, determining that the first operation has been received; the first coordinate axis is an X-axis, a Y-axis, or a Z-axis;

[0087] The display interface of the terminal is switched from the video call to the target image displayed in the second three-dimensional space, and the video call interface is hidden or reduced.

[0088] In the embodiment of the present application, the first coordinate axis is the Z axis; that is, the first operation is an operation of rotating the terminal around the Y axis by an angle greater than or equal to a preset angle.

[0089] It should be noted that if the first coordinate axis is the Z axis and the first operation is to rotate the terminal about the Y axis, the image of the first scene captured by the rotated camera is only an image captured at a different angle, and the captured image is still consistent with the actual scene.

[0090] If the first coordinate axis is the X-axis, and the first operation is rotating the terminal around the Z-axis, then after the rotation, the image of the first scene captured by the camera is rotated compared to the real scene, causing the constructed three-dimensional space to be inconsistent with the real scene, affecting the user's immersive experience;

[0091] If the first coordinate axis is the Y axis, the first operation is to rotate the terminal around the X axis. After the rotation, the image of the first scene captured by the camera is rotated compared to the real scene, resulting in the constructed three-dimensional space being inconsistent with the real scene, affecting the user's immersive experience.

[0092] Therefore, in the embodiment of the present application, the first coordinate axis is the Z axis.

[0093] like Figure 6 As shown, the display interface of the terminal is switched from the video call to the target image F displayed in the second three-dimensional space E, the video call interface is reduced, and displayed in the form of a thumbnail G on the viewing interface of the target image.

[0094] The image preview method of the embodiment of the present application can complete the viewing of the target image by rotating the terminal (the first operation), which is simple to operate and improves the user experience of viewing the image.

[0095] Optionally, the method further includes:

[0096] When it is detected that the angular deviation between the terminal and the first coordinate axis is less than a preset angle based on the position information of the terminal acquired in real time, the display interface of the terminal is switched to the video call.

[0097] In an embodiment of the present application, after the user previews the target image, the terminal is restored to its original position, that is, rotated back to the original position of the coordinate system; at this time, the viewing of the target image is completed, and the display interface of the terminal is switched back to the video call interface through this operation.

[0098] Optionally, the method further includes:

[0099] After receiving the target image, obtaining image information collected by the camera in real time;

[0100] The coordinate system and the second three-dimensional space are corrected according to the image information.

[0101] It should be noted that after the terminal receives the target image, image acquisition of the first scene by the camera is continuously performed, and as the terminal moves, the coordinate system and the second three-dimensional space are corrected according to image information collected by the camera, so that the constructed three-dimensional space is more consistent with the real first scene, thereby improving the immersive experience of the user.

[0102] Optionally, the method further includes:

[0103] The target position and the target pose at which the target image is displayed in the second three-dimensional space are saved to the target position of the terminal.

[0104] It should be noted that saving the target image not only saves the target image, but also saves the target position and the target pose of the target image in the second three-dimensional space.

[0105] The image preview method of the embodiment of the application can enable the user to still immerse in viewing the target image in the first scene when the user views the target image again subsequently, by saving the target position and the target pose at which the target image is displayed in the second three-dimensional space.

[0106] Optionally, the method further includes:

[0107] A second operation is received in the first scene; the second operation is used to access the target image in the target position;

[0108] The target image is displayed in a third three-dimensional space according to the target position and the target pose; the third three-dimensional space is the same as or different from the second three-dimensional space.

[0109] It should be noted that the third three-dimensional space being the same as or different from the second three-dimensional space can be understood as that the first scene is collected in different positions and / or at different angles to form a three-dimensional space.

[0110] In the embodiment of the application, the second operation is received in the first scene, and then the terminal collects images of the first scene by the camera, so as to reconstruct the third three-dimensional space, and display the target image in the target position and the target pose in the third three-dimensional space.

[0111] In the second scenario, the second operation is received in the embodiment of the present application. Since the terminal cannot collect image information in the first scenario, the three-dimensional space cannot be constructed for the first scenario, and the target image cannot be displayed in the three-dimensional space corresponding to the first scenario. Therefore, the target image can only be displayed or cannot be displayed.

[0112] The image preview method in the embodiment of the present application can restore the first scenario in which the user is located when the target image is received, and the display effect of the target image in the first scenario through the access to the target image in the target position in the first scenario, thereby improving the immersive experience of the user.
