In order to enable the user to have an immersive experience, a virtual scene can be constructed by applying VR technology. The virtual scene is built in two ways: the first is achieved by three-dimensional modeling; the second is to use a panoramic picture instead of the three-dimensional model.

Panoramic pictures, also known as 3D real scenes, are based on real-scene photographs, and are stitched and processed to synthesize viewpoint images, thereby giving a user a feeling of being in a picture environment. In the situation that a VR scene is built by using panoramic pictures, when the VR scene is switched, the scene watched by a user can only be switched to the scene presented by another group of panoramic pictures from the scene presented by one group of panoramic pictures, and the user can not experience the space roaming effect in the scene switching process, so that the immersion of the user is reduced, and the use experience of the user is influenced. Therefore, how to achieve the space roaming effect in the scene switching process to improve the user experience becomes one of the technical problems that needs to be solved at present.

At least one embodiment of the present disclosure provides a scene switching method based on a three-dimensional model and a full sedum empty box, which is applicable to a computing device, and the method includes: constructing a full-sedum empty box and a three-dimensional model, wherein when a first scene is displayed, the panoramic sky box comprises textures corresponding to the first scene, when a second scene is displayed, the panoramic sky box comprises textures corresponding to the second scene, and the first scene is different from the second scene; rendering for display using a first virtual camera in the three-dimensional model during a switch from a first scene to a second scene; in the process of switching from a first scene to a second scene, in the three-dimensional model, the first virtual camera is moved from a first viewpoint position corresponding to the first scene to a second viewpoint position corresponding to the second scene to realize the switching from the first scene to the second scene, wherein the first viewpoint position and the second viewpoint position are different.

Some embodiments of the present disclosure also provide a scene switching apparatus and a storage medium corresponding to the above-described scene switching method.

The scene switching method based on the three-dimensional model and the full sedum aizoon provided by the embodiment of the disclosure can realize switching of different scenes, has a space roaming effect in the scene switching process, has obvious space moving feeling, and improves the use experience of users.

Embodiments of the present disclosure and examples thereof are described in detail below with reference to the accompanying drawings.

At least one embodiment of the present disclosure provides a scene switching method, which may be applied to, for example, virtual house watching and the like. Fig. 1 is a flowchart of an example of a scene switching method according to at least one embodiment of the present disclosure. For example, the scene switching method may be implemented in a software, hardware, firmware, or any combination thereof, and may be loaded and executed by a processor in a device such as a mobile phone, a tablet computer, a notebook computer, a desktop computer, or a network server, so as to implement switching between different scenes, and have a spatial roaming effect during the scene switching process, thereby improving the user experience.

For example, the scene switching method is applicable to a computing device, which includes any electronic device with a computing function, for example, a mobile phone, a notebook computer, a tablet computer, a desktop computer, a web server, and the like, and the scene switching method may be loaded and executed, which is not limited in this respect by the embodiments of the present disclosure. For example, the computing device may include a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), or other Processing units with data Processing capability and/or instruction execution capability, a storage Unit, or other forms of storage units, and the like, and the computing device is installed with an operating system, an application programming interface (e.g., opengl (open Graphics library), Metal, or the like), and implements the scene switching method provided by the embodiments of the present disclosure by running codes or instructions. For example, the computing device may further include a Display component, such as a Liquid Crystal Display (LCD), an Organic Light Emitting Diode (OLED) Display, a Quantum Dot Light Emitting Diode (QLED) Display, a projection component, a VR head-mounted Display device (e.g., VR helmet, VR glasses), and so on, which are not limited in this regard. The display component may display a plurality of scenes (e.g., virtual scenes).

As shown in fig. 1, the scene switching method includes steps S110 to S120.

Step S110: and constructing a full-sedum empty box and a three-dimensional model, wherein when a first scene is displayed, the panoramic sky box comprises textures corresponding to the first scene, when a second scene is displayed, the panoramic sky box comprises textures corresponding to the second scene, and the first scene and the second scene are different.

Step S120: and in the process of switching from the first scene to the second scene, the first virtual camera in the three-dimensional model is used for rendering for display, and in the process of switching from the first scene to the second scene, the first virtual camera is moved from a first viewpoint position corresponding to the first scene to a second viewpoint position corresponding to the second scene in the three-dimensional model so as to realize the switching from the first scene to the second scene, wherein the first viewpoint position and the second viewpoint position are different.

The following description is given by taking an example that the scene switching method based on the three-dimensional model and the all-stonecrop empty box is applied to a virtual house-watching scene, but of course, the method can also be applied to other application scenes such as games and education, and the embodiment of the present disclosure is not limited thereto. For example, the scene switching method described above may be performed when the user performs virtual house viewing through a computing device such as a mobile phone, a computer, or the like.

For step S110, for example, when a single scene is displayed, that is, when a scene change is not performed, a picture of each scene may be displayed by the panoramic sky box. For example, when the first scene is displayed (e.g., before a scene switch is made), the panoramic sky box includes a texture corresponding to the first scene, that is, the first scene may be displayed through the panoramic sky box; when the second scene is displayed (e.g., after the scene switch is completed), the panoramic sky box includes a texture corresponding to the second scene, i.e., the second scene may be displayed through the panoramic sky box.

In the embodiment of the present disclosure, when a scene is not switched, the texture corresponding to the first scene or the texture corresponding to the second scene may be applied to the same full-sedum empty box in the corresponding time period according to a scene to be displayed, so that the first scene and the second scene may be displayed through one full-sedum empty box, that is, the first scene and the second scene may share one full-sedum empty box. It should be noted that the panoramic sky box may also display more scenes, and is not limited to the first scene and the second scene, and the embodiments of the present disclosure do not limit this.

For example, the first scene is a virtual scene that can be observed at a first viewpoint position, and the second scene is a virtual scene that can be observed at a second viewpoint position. For example, in some examples, the first scene and the second scene are different and, accordingly, the first viewpoint location and the second viewpoint location are also different. For example, the first scene and the second scene may be completely different scenes, e.g., the first scene may be located in a living room and the second scene may be located in a bedroom, or, e.g., the first scene may be located at an entrance position of the living room and the second scene may be located at an exit position of the living room; alternatively, the first scene and the second scene have a higher similarity but have a parallax, for example, a certain degree of parallax is generated due to a different viewing angle of the user or a different focusing position of the camera, and the embodiments of the present disclosure are not limited thereto.

For example, the texture corresponding to the first scene represents an image displayed after the panorama acquired in the first scene is attached to the rhodiola sacra empty box, that is, the texture of the rhodiola sacra empty box in the first scene. For example, the texture corresponding to the second scene represents an image displayed after the panorama acquired in the second scene is attached to the rhodiola sacra empty box, that is, the texture of the rhodiola sacra empty box in the second scene.

For example, the first viewpoint location and the second viewpoint location are both located in the full sedum empty box and in the three-dimensional model.

Fig. 2 is a flowchart of a method for constructing a full sedum empty box according to at least one embodiment of the present disclosure. That is, fig. 2 is a flowchart of some examples of step S110 shown in fig. 1. For example, in the example shown in fig. 2, the method of constructing the all-stonecrop empty box includes steps S111 to S1115. A method for constructing a full rhodiola rosea empty box according to at least one embodiment of the present disclosure is described in detail with reference to fig. 2.

Step S111: a first panorama of a first scene is acquired, wherein the first panorama comprises a plurality of first scene pictures at a first picture acquisition position.

Step S112: and acquiring a second panoramic image of the second scene, wherein the second panoramic image comprises a plurality of second scene pictures at the second picture acquisition position.

Step S113: the first viewpoint position is obtained based on the coordinates of the first picture acquisition position.

Step S114: and obtaining a second viewpoint position based on the coordinates of the second picture acquisition position.

Step S115: and constructing the full sedum aizoon blank box based on the first panorama of the first scene or the second panorama of the second scene.

For step S111, for example, the first panorama can be taken at the first picture taking position or rendered based on the first picture taking position. The first panorama is, for example, a group of pictures including a plurality of first scene pictures at the first picture capturing position. For example, the first panorama includes a first scene picture in a plurality of orientations such as front, rear, left, right, up, down, and the like at a first picture acquisition position as a center of a circle, which is taken in a cylindrical manner by moving an angle of the camera. For example, in some examples, when a first picture taking location is located in a room, a camera may be set to the first picture taking location and take a first scene picture (i.e., photograph) of four walls, front, back, left, right, etc., of the first picture taking location and a first scene picture (i.e., photograph) of a ceiling above and a floor below the first picture taking location. For example, the plurality of first scene pictures are seamlessly spliced, so that the first panorama can be obtained. For example, the seamless splicing technique may be implemented by a GPU, which is not described herein.

It should be noted that, in the embodiment of the present disclosure, the first panorama can be obtained by shooting, or can be obtained by drawing (for example, computer drawing or manual drawing) based on the first picture obtaining position, or can be generated by an image algorithm based on the first picture obtaining position, and a specific implementation manner may be determined according to an actual requirement, which is not limited in this embodiment of the present disclosure.

For example, in some examples, the first panorama may include 6 different orientation scene pictures, i.e., 6 orientation scene pictures including front, back, left, right, up, down, etc. at the first picture acquisition location, such that a complete and comprehensive scene may be presented in subsequent steps. For example, in other examples, the first panorama may include 5 first scene pictures of different orientations, i.e., including 5 orientations of front, back, left, right, and top at the first picture acquisition location, and no longer including the first scene picture below the first picture acquisition location. For example, when the first picture taking position is located in a certain room, since the texture of the floor is almost uniform in the room and does not change with the change of the place, and the user does not need to observe the texture of the floor, the first scene picture below the first picture taking position in the first panorama can be omitted, and only the first scene pictures of 5 orientations, front, rear, left, right, and the like, at the first picture taking position can be included, so that the data amount can be reduced.

For example, in step S112, the second panorama can be taken at the second picture taking position or rendered based on the second picture taking position. The second panorama is, for example, a group of pictures, including a plurality of second scene pictures at the second picture capturing position. For example, the second panorama includes pictures of the scene at a plurality of orientations, such as front, rear, left, right, up, down, and the like, at which the second picture is taken, in a cylindrical manner by moving the angle of the camera with respect to the second picture-taking position as a center. Similar to the manner of acquiring the first panorama, the second panorama may be obtained by shooting at the second picture acquiring position, may also be obtained by drawing (for example, computer drawing or manual drawing) based on the second picture acquiring position, and may also be generated by an image algorithm based on the second picture acquiring position, which may be determined according to actual needs, and this is not limited by the embodiments of the present disclosure.

For example, in some examples, the second panorama can include 6 second scene pictures of different orientations, i.e., including 6 orientations of front, back, left, right, up, down, etc., at the second picture acquisition location, such that a complete and comprehensive scene can be presented in subsequent steps. For example, in other examples, the second panorama may include 5 second scene pictures of different orientations, i.e., including 5 orientations of front, back, left, right, and top at the second picture acquisition location, and no longer including the second scene picture below the second picture acquisition location. When the scene pictures below the second picture taking position are omitted from the second panorama and only the second scene pictures of 5 orientations, front, rear, left, right, and top, at the second picture taking position are included, the amount of data can be reduced.

It should be noted that, in the embodiment of the present disclosure, the first panorama may be obtained in the same manner as the second panorama, for example, all the first panorama is obtained by shooting or all the second panorama is obtained by drawing, so that consistency of visual effects of users may be ensured. Of course, the embodiment of the present disclosure is not limited thereto, and the first panorama may be acquired in a different manner from the second panorama to meet diversified application requirements. For example, the first panorama is similar to the second panorama but has parallax, or the first panorama is completely different from the second panorama.

For example, in step S113, the first picture taking position is a location in the actual scene, and the first viewpoint position may be obtained from the coordinates of the first picture taking position. For example, the first viewpoint position is a position in a virtual scene corresponding to an actual scene at the first picture taking position, and thus, the first viewpoint position corresponds to a first picture taking position in the actual scene.

For example, in some examples, a two-dimensional plane map may be generated according to an actual scene, and a coordinate of the first picture obtaining position in the actual scene is labeled to the two-dimensional plane map, where the labeling point is the first viewpoint position. For example, since the user moves in the virtual scene generally horizontally in actual applications, the coordinates of the first picture taking position may be two-dimensional coordinates (i.e., coordinates in the horizontal plane) from which the first viewpoint position is marked in the two-dimensional plan view, which may reduce the amount of data.

Of course, the embodiments of the present disclosure are not limited thereto, and in other examples, the coordinates of the first picture capturing position may also be three-dimensional coordinates (that is, both the coordinates in the horizontal plane and the altitude are included), and accordingly, a three-dimensional stereo map needs to be generated according to the actual scene, and the first viewpoint position is marked in the three-dimensional stereo map according to the three-dimensional coordinates.

For example, in step S114, the second picture taking position is a location in the actual scene, and the second viewpoint position can be obtained from the coordinates of the second picture taking position. For example, the second viewpoint position is a position in a virtual scene corresponding to the actual scene, and the second viewpoint position corresponds to a second picture taking position in the actual scene.

For example, in some examples, similar to the manner of obtaining the first viewpoint position, a two-dimensional plane graph may be generated according to an actual scene, and a coordinate of the second picture obtaining position in the actual scene is labeled to the two-dimensional plane graph, where the labeling point is the second viewpoint position. The coordinates of the acquisition position of the second picture adopt two-dimensional coordinates, and the position of the second viewpoint is obtained by marking a two-dimensional plane graph, so that the data volume can be reduced. Of course, the embodiment of the present disclosure is not limited to this, in other examples, the coordinates of the second picture obtaining position may also be three-dimensional coordinates, and accordingly, a three-dimensional stereo image needs to be generated according to an actual scene, and the second viewpoint position is obtained by marking in the three-dimensional stereo image according to the three-dimensional coordinates.

For example, the first picture acquisition position is different from the second picture acquisition position. For example, the first picture taking location and the second picture taking location may be different locations in the same room, and the first picture taking location and the second picture taking location may also be located in different rooms. For example, the first picture acquisition location may be 1 meter, 2 meters, or any other distance from the second picture acquisition location. Accordingly, the first viewpoint position and the second viewpoint position may be different positions within the same room in the virtual scene, and the first viewpoint position and the second viewpoint position may also be located within different rooms in the virtual scene.

It should be noted that the first picture obtaining position and the second picture obtaining position may also be locations outdoors, and the first viewpoint position and the second viewpoint position may also be positions in an outdoor scene, which may be determined according to actual needs, and the embodiments of the present disclosure are not limited thereto.

For example, in step S115, a hexahedron as shown in fig. 3B is constructed, and when the first scene is displayed, the multiple first scene pictures in the first panorama are attached to different surfaces of the hexahedron, so as to construct a full-stonecrop empty box, so that when the first scene is displayed, the panoramic sky box includes a texture corresponding to the first scene; when the second scene is displayed, the plurality of second scene pictures in the second panoramic picture are attached to different surfaces of the hexahedron, so that the panoramic sky box is reconstructed, and when the second scene is displayed, the panoramic sky box comprises textures corresponding to the second scene. For example, the full sedum empty box may be constructed by performing a rendering operation in a processing unit, such as a graphics processing unit, by calling a graphics program interface (e.g., OpenGL) to attach the plurality of scene pictures in the first panorama to different surfaces of the hexahedron or attach the plurality of scene pictures in the second panorama to different surfaces of the hexahedron.

For example, as shown in fig. 3A, the first panorama or the second panorama includes 6 scene pictures with different orientations, i.e., front, rear, left, right, top, bottom, and the like. For example, scene pictures in different directions, such as front, back, left, right, up, and down, are attached to the surface of the hexahedron in the corresponding direction as shown in fig. 3B, so that the all-stonecrop empty box including different textures in different scenes can be obtained.

For example, as shown in fig. 3C, the full sedum empty box is a cube, and the center of the full sedum empty box is its geometric center, for example, the geometric center is located at the origin of a 3-dimensional coordinate system, i.e., the center of the full sedum empty box is located at the origin of coordinate axes, for example, the origin (0,0,0) of the coordinate axes shown in fig. 3C. The first viewpoint position A and the second viewpoint position B are both located in the panoramic sky box and are located at different positions in the panoramic sky box.

In order to interactively browse a virtual scene, a corresponding visible part in the virtual scene needs to be displayed according to the rotation angle of a user, so when the corresponding scene is presented by using a full sedum empty box, a second virtual camera needs to be arranged in a panoramic sky box, and when the corresponding scene is presented by using a three-dimensional model, a first virtual camera is arranged in the three-dimensional model. For example, the first virtual camera and the second virtual camera are used for rendering a portion visible to a user in a virtual scene, for example, the first virtual camera and the second virtual camera are implemented by corresponding program codes for rendering, which may refer to the design in the art and are not described herein again.

For example, the second virtual camera and the first virtual camera are the same virtual camera, or different virtual cameras. For example, the first virtual camera and the second virtual camera may be two identical cameras or two different cameras, so that the switching between the full sedum aizoon and the three-dimensional model may be more flexible, and of course, the same virtual camera may be used in the full sedum aizoon and the three-dimensional model instead of the first virtual camera and the second virtual camera, which is not limited in this embodiment of the present disclosure. For example, the position of the first virtual camera and the position of the second virtual camera correspond to the actual picture taking positions, respectively. For example, the position of the first virtual camera and the position of the second virtual camera correspond to the first picture taking position and the second picture taking position, respectively.

For example, in this example, when the scene is presented using the full sedentary blank, the scene switching method further includes: when a first scene is displayed, enabling a second virtual camera to be located at a first viewpoint position A corresponding to the first scene in the full sedum aizoon box; when the second scene is displayed, the second virtual camera is positioned at a second viewpoint position B corresponding to the second scene in the all-rhodiola rosea empty box, so that a user can respectively see complete space pictures corresponding to different scenes at different viewpoint positions. As for the method of rendering according to the rotation angle of the user by using the first virtual camera and the second virtual camera, reference may be made to the design in the art and detailed description thereof will be omitted.

For example, in a first scene, the texture of the full sedum empty box includes a plurality of rotated and shifted first scene pictures, and in a second scene, the texture of the full sedum empty box includes a plurality of rotated and shifted second scene pictures. For example, the displacement information of the plurality of first scene pictures and the displacement information of the plurality of second scene pictures are determined according to the coordinates of the first viewpoint position and the coordinates of the second viewpoint position, respectively.

Since the second virtual camera is not located at the center of the all-rhodiola rosea empty box (i.e. the origin of coordinates (0,0,0)), in order to see a complete spatial picture at the corresponding viewpoint position, a plurality of scene photos applied to the texture of the all-rhodiola rosea empty box are also displaced to a certain extent according to the viewpoint position of the second virtual camera, so that the user can see the complete spatial picture when the second virtual camera is located at the first viewpoint position or the second viewpoint position. For example, when a first scene is displayed, displacement information of a plurality of first scene pictures in a first panorama corresponding to the first scene corresponds to displacement information between a first viewpoint position a and a coordinate origin (0,0, 0); when the second scene is displayed, the displacement information of the plurality of second scene pictures in the second panorama corresponding to the second scene corresponds to the displacement information between the second viewpoint position B and the origin of coordinates (0,0, 0).

For example, a photograph taken at the image capturing position may have an inclination, and therefore, a plurality of first scene images and a plurality of second scene images may be subjected to rotation correction, so as to ensure that a scene seen through the virtual camera may be identical to an actual scene, thereby improving user experience.

For example, in some examples, the first and second panoramic views are pictures of a scene of the same room, and thus, the first and second scenes presented by the panoramic sky box are scenes of the same room. Since the first viewpoint position is different from the second viewpoint position, the first scene and the second scene have a certain parallax although located in the same room. For example, in other examples, the first and second panoramic views are pictures of scenes of different rooms, and thus, the first and second scenes presented by the panoramic sky box are scenes of different rooms. In an embodiment of the present disclosure, the first panorama and the second panorama may be any scene pictures, may be pictures of a room (for example, indoor pictures), or may be outdoor pictures, and the embodiment of the present disclosure is not limited to this.

It should be noted that, in the embodiment of the present disclosure, a manner of generating a full sky box by using a first panorama or a second panorama is not limited to the manner described above, and any applicable sky box generation method may be adopted, and only a first scene corresponding to the first panorama or a second scene corresponding to the second panorama is presented in the panoramic sky box, which is not limited in this respect.

It should be noted that, in the embodiment of the present disclosure, the shape of the total sedum empty box is not limited to a cube, and may also be any suitable shape such as a rectangular parallelepiped, a hexagonal prism, and the like, which may be determined according to actual needs, and the embodiment of the present disclosure is not limited to this. For example, in some examples, when the panoramic sky box presents a scene corresponding to a particular shaped room, such as a hexagonal wall instead of a typical four-sided wall, the panoramic sky box may include a hexagonal prism, and accordingly, the first and second panoramic views each include 8 differently oriented scene pictures, with the 8 scene pictures correspondingly fitting onto different surfaces of the hexagonal prism.

It should be noted that, in the embodiment of the present disclosure, when the first panoramic view and the second panoramic view respectively include 6 scene pictures with different orientations, 6 surfaces of the generated panoramic sky box each have a texture; when the first panoramic picture and the second panoramic picture respectively comprise 5 scene pictures with different directions, the surfaces of the 5 directions of the front direction, the rear direction, the left direction, the right direction and the upper direction of the generated all-sky box have textures, and the surface of the lower part has no textures, so that all the panoramic sky boxes are sky domes. For example, when the surface below the panoramic sky box is not textured, an image algorithm may be used to generate an image of the underlying surface, or the underlying surface may be filled with colors.

The general three-dimensional model has the disadvantages of large data volume, high development cost, large file and large rendering calculation amount, so that the blockage is easily caused, the system is delayed, and the like.

For example, in some embodiments of the present disclosure, the three-dimensional model is determined based on wall data of a picture obtaining scene (e.g., a broker actually takes a picture of a room), so that the amount of data required for running the three-dimensional model can be greatly reduced, and thus, the resource occupation space can be reduced, the power consumption of the system can be reduced, the operation is simple, the fluency of the system can be ensured, the jamming can be avoided, and the user experience can be improved. The specific construction method of the three-dimensional model can refer to the design in the field, and is not described herein again.

For example, a building unit may be provided, and the full sedum empty box and the three-dimensional model may be built by the building unit; the building unit may also be implemented, for example, by a Central Processing Unit (CPU), an image processor (GPU), a Tensor Processor (TPU), a Field Programmable Gate Array (FPGA) or other form of processing unit with data processing and/or instruction execution capabilities and corresponding computer instructions. For example, the processing unit may be a general purpose processor or a special purpose processor, may be a processor based on the X86 or ARM architecture, or the like.

For step S120, when the above three-dimensional model display is adopted in the scene switching process, the first panorama and the second panorama need to be applied to the above constructed three-dimensional model. For example, when a trigger event for switching from a first viewpoint position to a second viewpoint position is detected, a first virtual camera in the three-dimensional model is used for rendering for displaying, for example, showing an animation in the process of switching from a first scene to a second scene, so that a spatial roaming effect can be generated in the process of scene switching.

Fig. 4 is a flowchart of a method for applying the first panorama and the second panorama to the three-dimensional model constructed as described above according to at least one embodiment of the present disclosure. For example, as shown in fig. 4, the scene switching method further includes step S121 and step S122.

Step S121: a hybrid texture is obtained based on the first and second panoramas.

Step S122: the hybrid texture is applied to the three-dimensional model.

For step S121, for example, the first panorama and the second panorama are blended according to a certain perspective transformation to obtain a blended texture. That is, the mixed texture includes both the first panorama and the second panorama, for example, by adjusting transparency of the first panorama and transparency of the second panorama in the mixed texture, switching from a first scene corresponding to the first panorama to a second scene corresponding to the second panorama can be realized, and thus a spatial roaming effect can be realized in the three-dimensional model. The specific mixing method can refer to the design in the field and is not described herein.

For step S122, for example, the first panorama and the second panorama included in the mixed texture are applied to the three-dimensional model, and since the depth information is originally included in the three-dimensional model, and then the mixed texture is applied to the corresponding position in the three-dimensional model, the image with the depth information displayed in the three-dimensional model is the same as the image in the photograph, so that distortion caused by position errors of specific scenes such as doors and windows is avoided, thereby improving the reality of display and improving user experience.

For example, in moving the first virtual camera from the first viewpoint position to the second viewpoint position, the transparency of the first panorama in the blended texture is decreased along the time axis, and the transparency of the second panorama in the blended texture is increased along the time axis. For example, the transparency of the first panorama and the transparency of the second panorama are normalized. For example, the transparency of the first panorama decreases from 1 to 0 within a certain period of time, and the transparency of the second panorama increases from 0 to 1 within the same period of time. For example, a transparency of 1 for the first panorama indicates that the first panorama is opaque, and a transparency of 0 for the second panorama indicates that the second panorama is transparent, so the first scene is displayed; for example, a transparency of 1 for the second panorama indicates that the second panorama is opaque, and a transparency of 0 for the first panorama indicates that the first panorama is transparent, which shows the second scene. Therefore, the first scene presented in the three-dimensional model gradually disappears, and the second scene presented in the three-dimensional model gradually appears, so that the first scene corresponding to the first panoramic image is switched to the second scene corresponding to the second panoramic image in the three-dimensional model.

In the embodiment of the disclosure, by implementing the operation method in the three-dimensional model, the scene switching process seen by the user has the switching effect of fade-in and fade-out, and also has the effect of spatial roaming in the scene switching process, thereby improving the user experience.

For example, the transparency of the first panorama and the transparency of the second panorama each vary linearly in time, and thus may have a more uniform switching effect. Of course, the embodiments of the present disclosure are not limited thereto, and the transparency of the first panorama and the transparency of the second panorama may also be nonlinearly changed in time, respectively, to achieve a personalized switching effect.

For example, the transparency of the first panorama and the transparency of the second panorama vary over the same period of time. When the transparency of the first panorama begins to change, the transparency of the second panorama also begins to change. When the transparency of the first panorama is changed, the transparency of the second panorama is also changed.

For example, the time axis includes a time to move the first virtual camera from the first viewpoint position to the second viewpoint position, and a sum of a transparency of the first panorama in the blended texture and a transparency of the second panorama in the blended texture is 1. That is, during the change of the transparency of the first panorama and the transparency of the second panorama, the sum of both is always kept at 1.

For example, in the process of switching from a first scene to a second scene, the transparency of the first panorama is 1 (i.e., the first panorama is opaque) and the transparency of the second panorama is 0 (i.e., the second panorama is transparent) when the first scene is displayed; when the second scene is displayed, the transparency of the first panorama is 0 (i.e., the first panorama is transparent) and the transparency of the second panorama is 1 (i.e., the second panorama is opaque). For example, during a scene cut, when the texture transparency of the first panorama is 0.8, the transparency of the second panorama is 0.2. For example, during a scene cut, when the transparency of the first panorama is 0.5, the transparency of the second panorama is 0.5. For example, after the scene switching is completed, the transparency of the first panorama is 0, and the transparency of the second panorama is 1, and at this time, the user sees the second scene corresponding to the second panorama.

In this way, the transparency of the texture seen by the user (i.e., the superimposed texture of the transparency of the first panorama and the transparency of the second panorama in the mixed texture on the three-dimensional model seen by the user) can be always kept at 1, thereby ensuring the consistency of the visual effect of the user.

For example, before the process of switching from the first scene to the second scene begins, that is, when a single scene (i.e., the first scene) is displayed, the panoramic sky box is used for displaying at this time, for example, the first scene corresponding to the first viewpoint position is displayed by using the second virtual camera in the full sedum sky box.

For example, after the first virtual camera is moved from the first viewpoint position to the second viewpoint position, that is, a single scene (that is, a second scene) is displayed, for example, the second virtual camera in the all-stonecrop empty box is used to display the second scene corresponding to the second viewpoint position, that is, after the scene switching is completed, the three-dimensional model is hidden, and the all-stonecrop empty box is continuously used to display the second scene.

For example, at this time, the second panorama displayed in the three-dimensional model is applied to the full-rhodiola empty box to replace the first panorama on the panoramic sky box, so that after the scene switching is completed, the second scene corresponding to the second panorama is displayed through the full-rhodiola empty box.

For example, as shown in fig. 3C, the first virtual camera is moved from the first viewpoint position to the second viewpoint position in such a manner that: and obtaining a movement vector uAuuBr according to the first viewpoint position A and the second viewpoint position B, and enabling the first virtual camera to move to the second viewpoint position B along the movement vector uAuuBr by taking the first viewpoint position A as an initial point. For example, the moving route of the first virtual camera is a straight line, that is, the first virtual camera moves along a straight line between two points A, B. For example, the first virtual camera may move at a constant speed or at a variable speed, which is not limited in this embodiment of the disclosure. The position transformation algorithm for the first virtual camera may refer to conventional designs and will not be described in detail here.

It should be noted that, in the embodiment of the present disclosure, the operation of changing the transparency of the first panorama and the transparency of the second panorama is performed simultaneously with the operation of moving the first virtual camera from the first viewpoint position to the second viewpoint position. For example, the moving time of the first virtual camera is equal to the changing time of the transparency of the first and second panoramas, and the time when the first virtual camera starts to move is equal to the time when the transparency of the first and second panoramas starts to change. For example, the moving time of the first virtual camera (i.e., the time of the change of the transparency of the first and second panoramas) may be 1s, 5s, 10s, 30s, 1min or any other time, which is a switching time of switching the scene at the first viewpoint position to the scene at the second viewpoint position, which may be determined according to actual needs, and embodiments of the present disclosure are not limited thereto.

In a typical scene switching method, different scenes are realized by different sky boxes, for example, two sky boxes for presenting different scenes are centered at the same point, for example, both at the origin of coordinates, or at different points. Accordingly, the scene switching process is only achieved by moving the virtual camera from one sky box to another. Therefore, in the scene switching process, the user cannot feel the effect of the spatial roaming, and the switching effect is more obtrusive, which is different from the feeling of the user in the actual environment.

In contrast, in the scene switching method provided in the embodiment of the present disclosure, scenes before or after (i.e., when no) scene switching is performed are both displayed by the same panoramic sky box, but are not displayed by different rhodiola rosea empty boxes, and in the scene switching process, the first virtual camera in the three-dimensional model is moved from the first viewpoint position a to the second viewpoint position B, so that an effect of allowing the user to view the animation can be achieved in the scene switching process, and thus the user can have a feeling of spatial roaming, which is similar to the feeling of the user in an actual environment, thereby improving the use experience of the user.

For example, the scene switching method provided by the embodiment of the disclosure can be used for house-watching software. The user browses scenes (virtual scenes) of all rooms through the electronic terminal (such as a mobile phone, a computer and the like), so that the room does not need to be seen on the spot, the room-viewing efficiency is improved, and the user experience is also improved. Of course, the embodiments of the present disclosure are not limited thereto, and the scene switching method may be used in any scene, for example, may also be used in the fields of games, education, and the like, which may be determined according to actual needs, and the embodiments of the present disclosure are not limited thereto.

For example, a control unit may be provided and by means of the control unit, during a switch from a first scene to a second scene, rendering for display using a first virtual camera in the three-dimensional model; the control unit may also be implemented, for example, by a Central Processing Unit (CPU), an image processor (GPU), a Tensor Processor (TPU), a Field Programmable Gate Array (FPGA) or other form of processing unit with data processing and/or instruction execution capabilities and corresponding computer instructions.

At least one embodiment of the disclosure further provides a scene switching method based on the three-dimensional model and the full-rhodiola rosea empty box, and the method is suitable for a computing device. The scene switching method comprises the following steps: constructing a full-sedum empty box and a three-dimensional model, wherein when a first scene is displayed, the panoramic sky box comprises textures corresponding to the first scene, when a second scene is displayed, the panoramic sky box comprises textures corresponding to the second scene, and the first scene is different from the second scene; displaying a first scene by using a full sedum empty box, and executing the following method when an instruction for clicking a click mark of a second scene is received in the first scene: rendering for display by using a first virtual camera in a three-dimensional model, and in the three-dimensional model, moving the first virtual camera from a first viewpoint position corresponding to a first scene to a second viewpoint position corresponding to a second scene to realize switching from the first scene to the second scene, wherein the first viewpoint position and the second viewpoint position are different, the first viewpoint position corresponds to a click mark of the first scene, and the second viewpoint position corresponds to a click mark of the second scene; and after the switching from the first scene to the second scene is executed, displaying the second scene by using a second virtual camera in the full sedum aizoon.

Fig. 5 is a flowchart of another scene switching method according to at least one embodiment of the present disclosure. As shown in fig. 5, the scene switching method includes steps S210 and S240.

Step S210: and constructing a full sedum empty box and a three-dimensional model.

For example, when a first scene is displayed, the panoramic sky box comprises a texture corresponding to the first scene, when a second scene is displayed, the panoramic sky box comprises a texture corresponding to the second scene, and the first scene and the second scene are different. For example, the specific operation process of step S210 may refer to the specific description of step S110, which is not described herein again.

Step S220: the first scene is displayed using the full sedum empty box.

For example, when the location marker is located at the click marker of the first scene, the first scene is displayed using the second virtual camera in the full sedum aizoon. For example, when the scene switching method is performed using a mobile phone or a computer and the respective scenes are displayed, the position mark may be a cursor clicked with a finger on a touch screen, a touch pad, or a mouse, for example.

For example, the location marker is displayed via a display screen of the computing device (e.g., a display screen of a cell phone or a computer).

It should be noted that the position mark and the click mark are not necessarily provided, as long as the full sedum empty box display can be implemented when the scene switching is not performed, and the three-dimensional model display is used when the scene switching is performed, which is not limited by the embodiment of the present disclosure.

For example, the click mark of the first scene corresponds to a first viewpoint position. The cursor is located at the click mark of the first scene, namely, at the first viewpoint position, the single scene display is performed at the moment, and the scene switching does not exist, so that the first scene is displayed by using the second virtual camera in the full sedum aizoon box.

Step S230: when an instruction to click a click marker of a second scene is received in a first scene, rendering for display using a first virtual camera in a three-dimensional model.

For example, when an electrode mark of the second scene is clicked on a display screen of the computing device by finger touch or mouse, the processor of the computing device receives an instruction to click the click mark of the second scene in the first scene, so as to call program code stored in a memory, for example, to perform a corresponding scene switching operation.

For example, when there is an internal ground roaming point, e.g., when the click mark is a small circle on the ground, for example, a finger or mouse may be allowed to click within a certain range at the position of the click mark, e.g., within 15 degrees of the center of the click mark; for example, when there is no ground roaming point, when the click flag is an arrow, for example, a click at the arrow is needed to implement the instruction for triggering the scene change, which is not limited in this embodiment of the present disclosure.

For example, in the three-dimensional model, the first virtual camera is moved from a first viewpoint position corresponding to a first scene to a second viewpoint position corresponding to a second scene to realize the switching from the first scene to the second scene, the first viewpoint position and the second viewpoint position are different, the first viewpoint position corresponds to the click mark of the first scene, and the second viewpoint position corresponds to the click mark of the second scene.

For example, the specific operation process of step S230 may refer to the specific description of step S120 shown in fig. 1, and is not described herein again.

Step S240: and after the switching from the first scene to the second scene is executed, displaying the second scene by using the full sedum aizoon blank box.

For example, after the switching from the first scene to the second scene is performed, that is, when the position mark is located at the click mark of the second scene, the second scene is displayed by using the second virtual camera in the full sedum aizoon box. For example, the position mark is located at the click mark of the second scene, that is, the cursor is located at the second viewpoint position corresponding to the second scene, at this time, the scene switching is finished, that is, the single scene, that is, the second scene is displayed, so that the second scene is displayed by using the second virtual camera in the all-stonecrop empty box.

It should be noted that, in the embodiments of the present disclosure, the flow of the scene switching method provided in the above-mentioned embodiments of the present disclosure may include more or less operations, and these operations may be executed sequentially or in parallel. Although the flow of the scene switching method described above includes a plurality of operations that occur in a specific order, it should be clearly understood that the order of the plurality of operations is not limited. The scene switching method described above may be performed once or may be performed a plurality of times according to a predetermined condition.

The scene switching method based on the three-dimensional model and the full sedum aizoon provided by each embodiment of the disclosure can realize switching of different scenes, has a space roaming effect in the scene switching process, has obvious space moving feeling, and improves the use experience of users.

For example, the scene switching method provided by the foregoing embodiments may be implemented by the scene switching system shown in fig. 6. As shown in fig. 6, the scene switching system 10 may include a user terminal 11, a network 12, a server 13, and a database 14.

The user terminal 11 may be, for example, a computer 11-1, a cellular phone 11-2 shown in fig. 6. It is understood that the user terminal 11 may be any other type of electronic device capable of performing data processing, which may include, but is not limited to, a desktop computer, a laptop computer, a tablet computer, a smart phone, a smart home device, a wearable device, a vehicle-mounted electronic device, a monitoring device, and the like. The user terminal may also be any equipment provided with an electronic device, such as a vehicle, a robot, etc.

The user may operate an application installed on the user terminal 11, the application transmits user behavior data to the server 13 through the network 12, and the user terminal 11 may also receive data transmitted by the server 13 through the network 12. The user terminal 11 may implement the scene switching method provided by the embodiment of the present disclosure by running a sub program or a sub thread.

For example, when the user uses the house-watching software on the user terminal 11, the server 13 transmits the house source information browsed by the user to the user terminal 11 through the network 12, the house source information including a virtual scene of the house source and a three-dimensional model, a full stonecrop box and related data required for presenting the virtual scene. The house watching software on the user terminal 11 displays the virtual scene of the house source, and the user can switch scenes by clicking different viewpoint positions in the virtual scene of the house source. For example, the user terminal 11 may include a touch screen, and thus the user may directly click a position on the screen with a finger to effect switching of scenes. For example, the user terminal 11 may also include a mouse, so that the user clicks the position of the cursor on the screen with the mouse to realize the switching of scenes.

In some embodiments, the processing unit of the user terminal 11 may be utilized to execute the scene switching method provided by the embodiments of the present disclosure. In some implementations, the user terminal 11 may perform the scene switching method using an application built in the user terminal 11. In other implementations, the user terminal 11 may execute the scene switching method provided by at least one embodiment of the present disclosure by calling an application program stored outside the user terminal 11.

In other embodiments, the user terminal 11 transmits a received instruction to click on a click mark (i.e., viewpoint position) of a different scene to the server 13 via the network 12, and the scene switching method is performed by the server 13. In some implementations, the server 13 may perform the scene switching method using an application built in the server. In other implementations, the server 13 may perform the scene change method by calling an application stored outside the server 13.

The network 12 may be a single network or a combination of at least two different networks. For example, the network 12 may include, but is not limited to, one or a combination of local area networks, wide area networks, public networks, private networks, and the like.

The server 13 may be a single server or a group of servers, each connected via a wired or wireless network. A group of servers may be centralized, such as a data center, or distributed. The server 13 may be local or remote.

The database 14 may generally refer to a device having a storage function. The database 13 is mainly used to store various data utilized, generated, and outputted from the user terminal 11 and the server 13 in operation. For example, the database 14 stores a large amount of house source information, the server 13 reads the house source information required by the user from the database 14 and transmits the house source information to the user terminal 11 through the network 12, and the user terminal 11 displays a virtual scene of the house source, thereby facilitating the user to browse and switch scenes. The database 14 may be local or remote. The database 14 may include various memories such as a Random Access Memory (RAM), a Read Only Memory (ROM), and the like. The above mentioned storage devices are only examples and the storage devices that the system can use are not limited to these.

The database 14 may be interconnected or in communication with the server 13 or a portion thereof via the network 12, or directly interconnected or in communication with the server 13, or a combination thereof.

In some embodiments, the database 15 may be a stand-alone device. In other embodiments, the database 15 may also be integrated in at least one of the user terminal 11 and the server 14. For example, the database 15 may be provided on the user terminal 11 or may be provided on the server 14. For another example, the database 15 may be distributed, and a part thereof may be provided in the user terminal 11 and another part thereof may be provided in the server 14.

For example, in some examples, the above-described scene switching method may be applied to a plurality of displaced terminals in a synchronized presentation. For example, when a plurality of users located in different regions want to watch the same house, the scene switching method can be applied to synchronous display of a plurality of different terminals, so that efficient synchronous roaming display can be realized. For example, the plurality of remote terminals may be terminal devices, such as mobile phones or computers, used by different users located in different areas, such as Shanghai, Wuhan and Beijing. For example, the plurality of different users may be a family in different regions simultaneously watching a set of houses for negotiation convenience, or a plurality of users unrelated to each other. For example, the plurality of remote terminals are controlled and displayed by the terminal device as the main control terminal as the controlled terminal. For example, the master control end may be a terminal device used by a broker, for example, in the Shanghai. For example, the broker may perform operations such as displaying the first scene or the second scene and switching the first scene to the second scene on the terminal device used by the broker as the main control end, and correspondingly, when the main control end performs corresponding operations, the computing device may send corresponding operation instructions to the terminal devices serving as the controlled ends located in the other different areas (for example, the shanghai, wuhan, and beijing) to control the terminal devices to simultaneously display the same operation display as the main control end, thereby implementing synchronous display of a plurality of terminals in different places.

For example, in this example, when multiple terminal devices located in different regions and serving as controlled terminals perform synchronous roaming display, it is not necessary to transmit image data with a large data size to the multiple terminal devices, it is only necessary to transmit the image data with the large data size to the terminal device serving as the main control terminal to perform corresponding scene display and switching, and the terminal device serving as the controlled terminal only needs to perform the same display as the main control terminal under the control of an operation instruction sent by the main control terminal, so that the synchronous roaming display of multiple terminals in different places can be realized, thereby effectively reducing the data transmission size, reducing the transmission power consumption, being simple in operation, responding in time, and further improving the user experience.

Fig. 7 is a schematic block diagram of a scene switching apparatus according to at least one embodiment of the present disclosure. For example, in the example shown in fig. 7, the scene switching apparatus 100 includes a construction unit 110 and a control unit 120. For example, these units may be implemented by hardware (e.g., circuit) modules or software modules, and the following embodiments are the same and will not be described again.
