Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. It is to be understood that the described embodiments are merely exemplary of some, and not all, of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without any inventive step, are intended to be within the scope of the present disclosure.
In a conventional VR presentation-enabled device or application, when a user selects to view a VR interface of a target object (such as a certain room), there is often a white screen time before the VR interface of the target object is finally presented to the user, during which the user can only see a blank screen and wait for the final presentation of the VR interface. The white screen time is typically made up of two parts, the time required to build a web page view (webview), and the time required to load and render the VR interface of the target object in the webview. The existence of the white screen time seriously affects the experience of a user watching the VR interface, especially under the condition of poor network environment, the white screen time can be further prolonged, the time of the user waiting for the VR interface is increased, and the user experience is further deteriorated.
Therefore, the present disclosure provides a loading method, device, equipment, medium and computer program product for a virtual reality interface, which can effectively solve the problem of white screen time and greatly improve user experience.
Next, a loading method of a virtual reality interface according to an embodiment of the present disclosure is described first with reference to fig. 1. Fig. 1 shows a flowchart of a loading method 100 of a virtual reality interface according to an embodiment of the present disclosure. The loading 100 may be implemented in software, hardware, firmware or any combination thereof, and may be performed by, for example, a smart phone, a tablet computer, a notebook computer, a desktop computer, a web server, a Personal Digital Assistant (PDA), a smart wearable device, or the like, which is not specifically limited by the embodiments of the present disclosure.
As shown in fig. 1, in step S110, a presentation request for a virtual reality interface of a target object is received. In the disclosed embodiment, the target object may be any object whose virtual reality interface is to be presented, for example, a room of a building or the like. For example, if a user desires to view a virtual reality interface of a building room, a presentation request may be sent through a user interface or control located on the device performing the loading method 100. It should be understood that the target object is taken as a building room as an example, but the embodiments of the present disclosure are not limited thereto, and the target object may be any other object that can use virtual reality technology to show a virtual reality interface thereof.
In step S120, in response to receiving the presentation request, a plurality of images of the target object are acquired. In the disclosed embodiments, the plurality of images of the target object may be a plurality of images representing views of the target object in different orientations, e.g., the plurality of images may include a left view, a right view, a front view, a rear view, a top view, and a plan view, etc. of the target object. In an example where the target object is a building room, the plurality of images may comprise 6 views of the room, namely a left view, a right view, a front view, a rear view, a top view and a top view, the 6 views encompassing all views of the building room. In the embodiment of the present disclosure, the plurality of images of the target object may be acquired by the camera, for example, and may be stored in the storage device or the server in advance, and then in response to receiving the presentation request, the plurality of images may be acquired directly from the storage device or may be quickly loaded from the server.
Then, in step S130, a mask interface including a stereoscopic view of the target object is generated based on the acquired plurality of images, and the mask interface is displayed. In embodiments of the present disclosure, each of the plurality of images of the target object may constitute each of the stereoscopic views of the mask interface, which may present a stereoscopic view of the target object as the plurality of images may represent views of the target object in different orientations. For example, in case the plurality of images comprises 6 views, the mask interface may be a hexahedral interface representing a panoramic stereoscopic view of the target object, wherein each of the 6 views of the target object constitutes one face of the hexahedron. The mask interface may rotate, for example, by itself or by user manipulation, in different directions and speeds to present views of the target object in different orientations.
It should be noted that, although the above description is given by taking an example that the multiple views of the target object include 6 views and the mask interface is a hexahedral interface, the embodiments of the present disclosure are not limited thereto, the multiple views of the target object may include more or fewer views, and the mask interface generated based on the multiple views may also be any polyhedron or any interface with a three-dimensional structure.
Taking the example that the target object is a building room, for example, the plurality of images acquired in step S120 may include 6 views of a left view, a right view, a front view, a rear view, a top view, and a top view of the room, and based on the 6 views, a mask interface including a panoramic stereoscopic view representing the room may be generated, the mask interface being a hexahedron, and the hexahedron may be rotated to show views of the room in various orientations.
After the user sends a request for showing the virtual reality interface of the target object, for example, through a user interface or a control located on the device executing the loading method 100, a mask interface of the target object may be quickly generated through operations of steps S120 and S130 and presented to the user first, so as to avoid that only a white screen interface can be presented to the user before the virtual reality interface of the target object is rendered.
Meanwhile, in step S140, during the presentation of the mask interface, the virtual reality interface of the target object is loaded and rendered. As mentioned above, the generating of the virtual reality interface of the target object may include two processes, i.e., establishing a webview and loading the virtual reality interface rendering the target object in the webview, both of which may be performed in step S140, and step S140 may be performed by a processor of the device executing the loading method 100, for example. Moreover, during the display of the mask interface, the loading and rendering of the virtual reality interface of the target object are performed in the background, so that the display of the mask interface is not influenced, and the user cannot perceive the loading and rendering process.
According to an example of the embodiment of the present disclosure, after the plurality of images of the target object are acquired in step S120, the plurality of images may be stored in a cache; the plurality of images may be directly retrieved from the cache and a virtual reality interface of the rendering target object may be loaded based on the plurality of images in step S140. By multiplexing the acquired images, the speed of generating the virtual reality interface can be further increased, and the loading efficiency is improved.
In step S150, after the rendering of the virtual reality interface of the target object is completed, the mask interface is hidden and the virtual reality interface of the target object is displayed.
As previously described, the mask interface of the target object may be rotated to show the view of the target object in different orientations. Likewise, the virtual reality interface of the target object may also be rotated to present a virtual reality view of the target object in different orientations. In addition, the virtual reality interface of the target object can also be zoomed and the like so as to show virtual reality views of the target object in different orientations at different angles of view. And the virtual reality interface of the target object can also be provided with one or more user interactive modules, so that a user can initiate interactive operation based on the virtual reality interface through the one or more user interactive modules.
After a user sends a display request for a virtual reality interface of a target object, a mask interface of the target object is quickly generated and displayed to the user, the virtual reality interface of the rendered target object is loaded in a background mode during the display period of the mask interface, and after the rendering of the virtual reality interface is completed, the mask interface is hidden and the virtual reality interface is displayed, so that the problem of screen blank time during the loading and rendering of the virtual reality interface can be effectively solved. In addition, in order to further improve the user experience, it is desirable that the user does not perceive the switching process from the mask interface to the virtual reality interface, and it is necessary to enable the mask interface to be seamlessly connected with the virtual reality interface displayed later, so as to make smooth transition.
Specifically, after rendering of the virtual reality interface of the target object is complete, an instruction indicating that rendering of the virtual reality interface is complete may be issued, for example, by webview. In response to receiving the instruction, current visual parameters of a mask interface of the target object may be obtained, wherein the visual parameters may include at least a current field angle, a current azimuth angle, a current steering, a current rotation speed, and so on of the target object in the mask interface. The current field angle may represent a field size or a zoom scale at which the user is currently viewing the target object; the current azimuth may represent a specific azimuth at which the user currently views the target object, for example, in an example where the mask interface is a hexahedral interface, which face of the hexahedron the user views may be represented; as previously mentioned, the mask interface may be rotated, and the current turn and current rotation speed represent the current turn and current rotation speed of the mask interface, or more specifically, the target object in the mask interface.
After the visual parameters of the mask interface of the target object are acquired, the mask interface can be hidden, and the virtual reality interface of the target object is displayed based on the visual parameters, so that the visual effects of the target object in the displayed virtual reality interface and the target object in the mask interface are kept consistent. That is, the target object in the virtual reality interface may be presented with the current field angle, the current azimuth, the current yaw, and the current yaw rate of the target object in the mask interface to keep the field angle, the azimuth, the yaw rate, and the yaw rate of the target object in the virtual reality interface consistent with those of the target object in the mask interface.
Through the operation, the field angle, the azimuth angle, the steering direction, the rotating speed and the like of the target object are kept consistent before and after the mask interface is switched to the virtual reality interface, namely the visual effect of the target object is completely the same for the user, and the mask interface and the virtual reality interface can respond to the same user operation. Thus, the user does not perceive the switch from the mask interface to the virtual reality interface, resulting in an optimal user experience.
The target object is further explained with reference to fig. 2 as a building room. Fig. 2 shows a schematic diagram of an example mask interface and virtual reality interface, according to an embodiment of the present disclosure. In this example, after issuing a virtual reality exhibition request for a certain room, the user first generates a mask interface for the room, which is a hexahedron representing a stereoscopic view of the room, according to the method as described in the above steps S110-S130. The hexahedron may rotate on its own at a set rotational speed, or the user may operate to rotate the hexahedron to view a view of a certain orientation of the room. For example, the user may rotate the hexahedron to see a view of the room in azimuth β, as shown in fig. 2 (a).
During the displaying of the mask interface of the room, the virtual reality interface of the room may be loaded and rendered in the background according to the step S140, and after the rendering is completed, the mask interface is hidden and the virtual reality interface is displayed. As described in the above step S150, before switching from the masking interface to the virtual reality interface, the visual parameters of the masking interface, such as the current field angle, the current azimuth angle, the current steering direction, and the current rotation speed, of the target object may be obtained, and the virtual reality interface displayed later may be made to be consistent with the visual effect in the masking interface. For example, assume that before switching from the mask interface to the virtual reality interface of the room, the user views the room with an angle of view α, an azimuth β, a clockwise direction of rotation, and a rotational speed r, as shown in fig. 2 (a); after switching to the virtual reality interface, the angle of view of the room in the virtual reality interface can be also α, the azimuth angle is also β, the direction of rotation is also clockwise, and the rotation speed is also r, as shown in fig. 2 (b).
Thus, before and after the switch, due to the smooth transition from the mask interface to the virtual reality interface, the visual effect of the room seen by the user is seamless, and the user does not perceive the change of the picture from the mask interface to the real virtual reality interface. The difference is that in the virtual reality interface of the room, the user can perform more operations based on the virtual reality interface, for example, the user can perform operations such as zooming on the room; a watch-with call may be initiated to communicate with the house broker in a room-based virtual reality interface, and so on.
In addition, according to an example of the embodiment of the present disclosure, optionally, the presentation request for the virtual reality interface of the target object received in step S110 may include a configuration protocol parameter, which may indicate whether the loading method as described in steps S120 to S150 is adopted or not, for example, to solve the white screen time problem. If the configuration protocol parameters indicate that the loading method as described in steps S120-S150 is adopted, the operations of steps S120-S150 may be continuously performed; otherwise, steps S120-S130 may be omitted, i.e., the mask interface of the target object is not generated, and the virtual reality interface of the target object is directly loaded and rendered.
According to the loading method of the virtual reality interface, the mask interface of the target object is quickly generated and displayed to a user, meanwhile, the virtual reality interface of the rendering target object is loaded in the background during the display period of the mask interface, after the rendering of the virtual reality interface is completed, the mask interface is hidden and the virtual reality interface is displayed, the problem of screen blank time during the loading and rendering of the virtual reality interface can be effectively solved, and the problem of screen blank time caused by the establishment of webview and the loading and rendering of the virtual reality interface in webview can be effectively solved; meanwhile, the user can not perceive the switching from the mask interface to the virtual reality interface through smooth transition and seamless connection from the mask interface to the virtual reality interface, and therefore user experience is improved to the maximum extent. In particular, the loading method of the virtual reality interface according to the embodiment of the present disclosure is particularly suitable for a situation where a user loads the virtual reality interface of the target object for the first time (i.e., first screen loading), so that the user does not have to face the trouble of the white screen time problem.
A loading apparatus of a virtual reality interface according to an embodiment of the present disclosure is described below with reference to fig. 3. Fig. 3 shows a schematic structural diagram of a loading device 300 of a virtual reality interface according to an embodiment of the present disclosure. As shown in fig. 3, the loading device 300 includes a receiving unit 310, an obtaining unit 320, a presentation unit 330, and a rendering unit 340. The loading device 300 may include other units or components in addition to the four units, but a detailed description thereof is omitted herein since the units or components are not related to the embodiments of the present disclosure. In addition, since part of the functions of the loading device 300 are the same as the details of the steps of the loading method 100 described above with reference to fig. 1, repeated descriptions of the same are omitted here for the sake of simplicity.
The receiving unit 310 is configured to receive a presentation request for a virtual reality interface of a target object. In the disclosed embodiment, the target object may be any object whose virtual reality interface is to be presented, for example, a room of a building or the like. For example, if a user desires to view a virtual reality interface of a building room, a presentation request may be sent through a user interface or control on the loading device 300. It should be understood that the target object is taken as a building room as an example, but the embodiments of the present disclosure are not limited thereto, and the target object may be any other object that can use virtual reality technology to show a virtual reality interface thereof.
The obtaining unit 320 is configured to obtain a plurality of images of the target object in response to receiving the presentation request. In the disclosed embodiments, the plurality of images of the target object may be a plurality of images representing views of the target object in different orientations, e.g., the plurality of images may include a left view, a right view, a front view, a rear view, a top view, and a plan view, etc. of the target object. In an example where the target object is a building room, the plurality of images may comprise 6 views of the room, namely a left view, a right view, a front view, a rear view, a top view and a top view, the 6 views encompassing all views of the building room. In the embodiment of the present disclosure, the plurality of images of the target object may be acquired by the camera, for example, and may be stored in the storage device or the server in advance, and in response to receiving the presentation request, the acquiring unit 320 may acquire the plurality of images directly from the storage device or may quickly load the plurality of images from the server.
Thereafter, the presentation unit 330 is configured to generate a mask interface including a stereoscopic view of the target object based on the acquired plurality of images, and present the mask interface. In embodiments of the present disclosure, each of the plurality of images of the target object may constitute each of the stereoscopic views of the mask interface, which may present a stereoscopic view of the target object as the plurality of images may represent views of the target object in different orientations. For example, in case the plurality of images comprises 6 views, the mask interface may be a hexahedral interface representing a panoramic stereoscopic view of the target object, wherein each of the 6 views of the target object constitutes one face of the hexahedron. The mask interface may rotate, for example, by itself or by user manipulation, in different directions and speeds to present views of the target object in different orientations.
It should be noted that, although the above description is given by taking an example that the multiple views of the target object include 6 views and the mask interface is a hexahedral interface, the embodiments of the present disclosure are not limited thereto, the multiple views of the target object may include more or fewer views, and the mask interface generated based on the multiple views may also be any polyhedron or any interface with a three-dimensional structure.
Taking the example that the target object is a building room, for example, the plurality of images acquired by the acquisition unit 320 may include 6 views of a left view, a right view, a front view, a rear view, a top view, and a top view of the room, and based on the 6 views, a mask interface including a panoramic stereoscopic view representing the room may be generated, the mask interface being a hexahedron, and the hexahedron may be rotated to show views of the room in various orientations.
After the user sends a display request for the virtual reality interface of the target object, for example, through the user interface or the control on the loading device 300, a mask interface of the target object may be quickly generated through the operations of the obtaining unit 320 and the display unit 330, and may be presented to the user, so as to avoid that only a white screen interface may be presented to the user before the virtual reality interface of the target object is rendered.
Meanwhile, during the presentation of the mask interface, the rendering unit 340 may load and render the virtual reality interface of the target object. As mentioned above, generating the virtual reality interface of the target object may include two processes, namely, establishing a webview in which the virtual reality interface rendering the target object is loaded, both of which may be executed by the rendering unit 340 and may be performed, for example, by the processor of the loading apparatus 300. Moreover, during the display of the mask interface, the loading and rendering of the virtual reality interface of the target object are performed in the background, so that the display of the mask interface is not influenced, and the user cannot perceive the loading and rendering process.
According to an example of the embodiment of the present disclosure, after the obtaining unit 320 obtains the plurality of images of the target object, the plurality of images may be stored in a cache; the rendering unit 340 may directly acquire the plurality of images from the cache and load a virtual reality interface of the rendering target object based on the plurality of images. By multiplexing the acquired images, the speed of generating the virtual reality interface can be further increased, and the loading efficiency is improved.
After the rendering of the virtual reality interface of the target object is completed, the presentation unit 330 may hide the mask interface and present the virtual reality interface of the target object.
As previously described, the mask interface of the target object may be rotated to show the view of the target object in different orientations. Likewise, the virtual reality interface of the target object may also be rotated to present a virtual reality view of the target object in different orientations. In addition, the virtual reality interface of the target object can also be zoomed and the like so as to show virtual reality views of the target object in different orientations at different angles of view. And the virtual reality interface of the target object can also be provided with one or more user interactive modules, so that a user can initiate interactive operation based on the virtual reality interface through the one or more user interactive modules.
After a user sends a display request for a virtual reality interface of a target object, a mask interface of the target object is quickly generated and displayed to the user, the virtual reality interface of the rendered target object is loaded in a background mode during the display period of the mask interface, and after the rendering of the virtual reality interface is completed, the mask interface is hidden and the virtual reality interface is displayed, so that the problem of screen blank time during the loading and rendering of the virtual reality interface can be effectively solved. In addition, in order to further improve the user experience, it is desirable that the user does not perceive the switching process from the mask interface to the virtual reality interface, and it is necessary to enable the mask interface to be seamlessly connected with the virtual reality interface displayed later, so as to make smooth transition.
Specifically, after the rendering unit 340 completes rendering the virtual reality interface of the target object, an instruction indicating that the rendering of the virtual reality interface is completed may be issued, for example, by webview. In response to receiving the instruction, the presentation unit 340 may obtain current visual parameters of a mask interface of the target object, where the visual parameters may include at least a current angle of view, a current azimuth, a current steering, a current rotation speed, and the like of the target object in the mask interface. The current field angle may represent a field size or a zoom scale at which the user is currently viewing the target object; the current azimuth may represent a specific azimuth at which the user currently views the target object, for example, in an example where the mask interface is a hexahedral interface, which face of the hexahedron the user views may be represented; as previously mentioned, the mask interface may be rotated, and the current turn and current rotation speed represent the current turn and current rotation speed of the mask interface, or more specifically, the target object in the mask interface.
After the visual parameters of the mask interface of the target object are obtained, the display unit 340 may hide the mask interface and display the virtual reality interface of the target object based on the visual parameters, so that the visual effects of the target object in the displayed virtual reality interface and the target object in the mask interface are kept consistent. That is, the presentation unit 340 may present the target object in the virtual reality interface at the current field angle, the current azimuth, the current rotation speed, and the current rotation speed of the target object in the mask interface, so that the field angle, the azimuth, the rotation speed, and the rotation speed of the target object in the virtual reality interface are consistent with those of the target object in the mask interface.
Through the operation, the field angle, the azimuth angle, the steering direction, the rotating speed and the like of the target object are kept consistent before and after the mask interface is switched to the virtual reality interface, namely the visual effect of the target object is completely the same for the user, and the mask interface and the virtual reality interface can respond to the same user operation. Thus, the user does not perceive the switch from the mask interface to the virtual reality interface, resulting in an optimal user experience.
The target object is further explained with reference to fig. 2 as a building room. In this example, after issuing a virtual reality presentation request for a certain room, a user first generates a mask interface for the room, which is a hexahedron representing a stereoscopic view of the room, by the obtaining unit 320 and the presentation unit 330. The hexahedron may rotate on its own at a set rotational speed, or the user may operate to rotate the hexahedron to view a view of a certain orientation of the room. For example, the user may rotate the hexahedron to see a view of the room in azimuth β, as shown in fig. 2 (a).
During the presentation of the mask interface of the room, the virtual reality interface of the room may be loaded and rendered in the background by the rendering unit 340, and after the rendering is completed, the mask interface is hidden by the presentation unit 330 and the virtual reality interface is presented. As described above, before switching from the mask interface to the virtual reality interface, the visual parameters of the target object in the mask interface, such as the current field angle, the current azimuth angle, the current steering direction, and the current rotation speed, may be obtained, and the visual effect of the virtual reality interface displayed later may be consistent with the visual effect of the mask interface. For example, assume that before switching from the mask interface to the virtual reality interface of the room, the user views the room with an angle of view α, an azimuth β, a clockwise direction of rotation, and a rotational speed r, as shown in fig. 2 (a); after switching to the virtual reality interface, the angle of view of the room in the virtual reality interface can be also α, the azimuth angle is also β, the direction of rotation is also clockwise, and the rotation speed is also r, as shown in fig. 2 (b).
Thus, before and after the switch, due to the smooth transition from the mask interface to the virtual reality interface, the visual effect of the room seen by the user is seamless, and the user does not perceive the change of the picture from the mask interface to the real virtual reality interface. The difference is that in the virtual reality interface of the room, the user can perform more operations based on the virtual reality interface, for example, the user can perform operations such as zooming on the room; a watch-with call may be initiated to communicate with the house broker in a room-based virtual reality interface, and so on.
In addition, according to an example of the embodiment of the present disclosure, optionally, the display request for the virtual reality interface of the target object received by the receiving unit 310 may include a configuration protocol parameter, which may indicate, for example, whether to adopt the loading method executed by the obtaining unit 320, the displaying unit 330, and the rendering unit 340 as described above, so as to solve the white screen time problem. If the configuration protocol parameters indicate that the loading methods of the obtaining unit 320, the presentation unit 330 and the rendering unit 340 are adopted, the above operations may be continuously performed; otherwise, the virtual reality interface of the target object can be directly loaded and rendered without generating the mask interface of the target object.
According to the loading device of the virtual reality interface, the mask interface of the target object is quickly generated and displayed to a user, meanwhile, the virtual reality interface of the rendered target object is loaded in the background during the display period of the mask interface, and after the rendering of the virtual reality interface is completed, the mask interface is hidden and the virtual reality interface is displayed, so that the problem of screen blank time during the loading and rendering of the virtual reality interface can be effectively solved, and the problem of screen blank time caused by the establishment of webview and the loading and rendering of the virtual reality interface in webview can be effectively solved; meanwhile, the user can not perceive the switching from the mask interface to the virtual reality interface through smooth transition and seamless connection from the mask interface to the virtual reality interface, and therefore user experience is improved to the maximum extent. In particular, the loading method of the virtual reality interface according to the embodiment of the present disclosure is particularly suitable for a situation where a user loads the virtual reality interface of the target object for the first time (i.e., first screen loading), so that the user does not have to face the trouble of the white screen time problem.
