Detailed Description
Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are illustrated in the accompanying drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.
In describing embodiments of the present disclosure, the terms "include" and its derivatives should be interpreted as being inclusive, i.e., "including but not limited to. The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". Other explicit and implicit definitions are also possible below.
As described above, in the related industries such as buildings and real estate, a three-dimensional model for showing information on the spatial layout, shape, area, and the like of a building can be provided to a user using VR technology. For example, in the house renting and selling industry, a user may be presented with a three-dimensional model of a house to be rented or sold so that the user may perform panoramic roaming of the house online.
Panoramic roaming of a house involves different viewing angles of the house. In the process that a user carries out panoramic roaming on a house through VR, multiple times of visual angle conversion can be carried out. For example, in a current scene of a house presented to a user, if the user clicks a certain position on a display device used to present the current scene, the perspective presented to the user may jump.
Because the number of points which may trigger browsing view angles in the panoramic roaming of a house is large, the view angle conversion in the panoramic roaming cannot be controlled at present. The user may switch the viewing angle to a viewing angle that is a very far distance from the current scene after clicking a certain location of the display device, or may not be able to switch the viewing angle because there is no point at that location that can trigger the viewing angle switch, which causes a degradation in the user experience.
According to various embodiments of the present disclosure, a scheme of controlling view angle conversion is proposed. For example, the electronic device may acquire at least one parameter related to the perspective transformation. The electronic device may determine a target field of view region in the current scene of the target space in which a transition point for triggering a perspective transition may exist based on the at least one parameter and the determined one position in the current scene. According to the transition point in the target view field region, it is possible to switch from a current scene presenting the target space to another scene presenting the target space corresponding to the switching point.
According to the realization of the method and the device, the browsing visual angle of the scene in the target space can be controlled, so that personalized browsing requirements are realized, and the user experience is further improved.
Example Environment
Referring initially to FIG. 1, a schematic diagram of an example environment 100 is schematically illustrated in which an example implementation according to the present disclosure may be implemented.
In the example environment 100, the acquisition device 140 may acquire images relating to a target space in the building 130. In some embodiments, the capture device 140 may be implemented as a panoramic camera. In some other embodiments, the acquisition device 140 may also be implemented as other devices capable of performing the capturing of images of the target space. Acquisition device 140 may acquire images of the target space at different location points in one or more buildings 130.
Optionally, the capture device 140 may be connected to the electronic device 110 or integrated within the electronic device 110. The capture device 140 may transmit the captured image to the electronic device 110.
The electronic device 110 is installed with an application 120. In some embodiments, the application 150 may be an application associated with a house rental sale. In some other embodiments, the application 150 may also relate to other services related to the construction industry. The application 150 may implement processing for images acquired in the building 130 and provide a three-dimensional model of a house based on the processed images. User 102 may interact with application 150 via electronic device 110 and/or an attached device of electronic device 110.
By way of example, the application 120 may generate a three-dimensional model of a target space in the building 130 based on images captured by the capture device 140 and, in turn, provide the user 102 with panoramic navigation of the target space in the building 130. In panoramic navigation of the target space by the user 102, the application 120 may present the user 102, e.g., via a display device (not shown), with a scene graph 150 of different perspectives of the target space. The user 102 may perform the transformation of different view angles of the target space during the panoramic roaming process.
In some embodiments, the electronic device 110 may be any type of mobile terminal, fixed terminal, or portable terminal including a mobile handset, desktop computer, laptop computer, notebook computer, netbook computer, tablet computer, media computer, multimedia tablet, Personal Communication System (PCS) device, personal navigation device, Personal Digital Assistant (PDA), audio/video player, digital camera/camcorder, positioning device, television receiver, radio broadcast receiver, electronic book device, game device, or any combination of the preceding, including accessories and peripherals of these devices, or any combination thereof. In some embodiments, the electronic device 110 can also support any type of interface to the user (such as "wearable" circuitry, etc.). The remote device 120 may be, for example, various types of computing systems/servers capable of providing computing capabilities, including but not limited to mainframes, edge computing nodes, computing devices in a cloud environment, and so forth.
It should be understood that the description of the structure and function of environment 100 is for exemplary purposes only and does not imply any limitation as to the scope of the disclosure.
View angle conversion process
Fig. 2 illustrates a flow diagram of a process 200 for controlling perspective conversion according to some embodiments of the present disclosure. Process 200 may be implemented at electronic device 110. For ease of discussion, the process 200 will be described with reference to the environment 100 of FIG. 1.
As shown in fig. 2, at block 210, the electronic device 110 obtains at least one parameter associated with a perspective transformation of a target space of the building 130.
Fig. 3 illustrates a schematic diagram of an operator interface for inputting parameters for controlling perspective transitions, in accordance with some embodiments of the present disclosure. As shown in fig. 3, in some embodiments, the electronic device 110, e.g., via the application 120, may present a user interface element 300 for controlling perspective conversion and receive an input value for at least one parameter via the user interface element 300.
An input window 310 for inputting a range of hot zone filters may be included in the user interface element 300, for example. In the present disclosure, the term "hotspot" may relate to a planar region associated with a position point selected by a user in a scene of a presented target space in a three-dimensional coordinate system of the scene, a value of the hotspot may be input through the input window 310, and the value of the hotspot may be regarded as a length value in the coordinate system of the scene of the target space. The range of values that the hot zone range filter may allow for entry may be indicated at the input window 310. For example 0-2 (meters). The user 102 enters arbitrary values through the input window 310 to define the range of the hotspot within the range of the interval.
An input window 320 for inputting the range of the angle filtering may also be included in the user interface element 300, for example. In the present disclosure, the term "angle" may relate to a field angle in a three-dimensional coordinate system of a scene of the presented target space from a position point of a camera associated with the acquisition of the scene towards a direction of one position point selected by the user in the scene, wherein a line connecting the camera position point and the position point selected by the user may be regarded as a bisector. The value of the included angle may be entered through the input window 320. An angle range may be indicated at the input window 320 to filter the range of values that may be allowed to be input. For example, 0-75 degrees. The user 102 defines the angle by entering an arbitrary value through the input window 320 within the range of the interval.
It should be understood that the viewing angle transition may be controlled based on other parameters besides the hot zone range and the angle selection. For example, a distance between a transition point triggering a view transition and a location point selected by the user under the current scene may be defined. In the case where there are a plurality of transition points that can trigger a view angle transition, an appropriate transition point can be selected by the distance. This process will be further explained below.
Referring back to fig. 2, at block 220, if the electronic device 110 detects a selection of a first location in a currently presented first scene of the target space, at block 230, the electronic device 11 determines a target field of view region based on the first location and at least one parameter.
Fig. 4A illustrates a currently presented first scene 410 of a target space of a building 130. The user interface element 300 for controlling perspective transition may be presented simultaneously with the first scene 410.
In some embodiments, if the electronic device 110 detects that the user 102 selects the location 401 in the currently presented first scene 410, for example, the user 102 clicks the location 401 with a mouse or touches the location 401 with a finger, the electronic device 110 may, for example, obtain the hot zone filtering parameters input by the user to determine the target field of view area 402, i.e., the hot zone range. In fig. 4A, the range of the target field of view region 402 may be a circular region with a radius 405 around the position 401 selected by the user 102 and the input hot zone filtering parameters in the three-dimensional coordinate system of the presented first scene 401. It should be appreciated that the circular region shown in fig. 4A may be used as an example of the determined target field of view region. The target field of view region 402 determined based on the location 401 selected by the user 102 and the hotspot screening parameters may also be a region having other shapes, such as a square, a regular triangle, or other regular polygon.
In some embodiments, the electronic device 110 may also obtain, for example, user-entered angle parameters to determine the target field of view area 404. In fig. 4A, the extent of the target field of view region 404 may be a cone region determined based on a positional relationship between the position 401 selected by the user 102 and the position 403 of the camera associated with the scene image acquisition of the first scene 401 and the user-input angle in the three-dimensional coordinate system of the presented first scene 401. The angle 406 may be the apex angle of the cone, the distance between position 401 and position 403 may be the height of the cone, and the plane determined with reference to position 401 may be the base of the cone. It should be appreciated that the cone region shown in FIG. 4A may be used as an example of the determined target field of view region. The target field of view region 404 determined based on the angle parameters may also be any other spatial geometry.
It should be appreciated that the user 102 may be given one or multiple parameters for controlling the perspective transition at the same time, and the electronic device 110 may determine the different target field of view regions 402 and/or 404 based on one or more of the parameters.
In this way, the determination of the target field of view area including the transition point can be realized according to the user requirement, so that a personalized panoramic roaming process can be realized, and the user experience is further improved.
Alternatively or additionally, in order to be able to visually present the target field of view determined according to the parameters for controlling the view angle transition and the position in the current scene selected by the user, the target field of view may be marked explicitly on the currently presented first scene. For example, in the manner of grid-line filling as presented in fig. 4A. Additionally, whether to explicitly label the target field of view region on the currently presented first scene may also be implemented in accordance with a selection input by the user at the user interface element 300. Thereby, it is possible to show the user in a more visual way which areas the device may switch in view depending on which switching points within.
Alternatively or additionally, an information cue regarding the switching of the viewing angle may also be presented on the currently presented first scene. For example, when the electronic device 110 detects a selection for a location in the currently presented first scene and determines a target field of view region, the electronic device 110 will present cues of view switching that may occur, such as whether or not view transition occurs, whether view jump involves a change in camera orientation, and so forth. In this way, the user can be more intuitively informed of the trend of the next view angle conversion.
At block 240, the electronic device 110 may render a second scene of the target space based on the target transition point associated with the target field of view region.
In some embodiments, multiple transition points may be included within the target field of view determined by electronic device 110. In this case, the electronic device 110 may obtain information associated with the selection of the transition point. In some embodiments, this information may also be input, for example, as a parameter for controlling the perspective conversion. The information may, for example, indicate that the transition point closest to the user 102 at the selected location 401 in the first scenario 410, or the transition point furthest from the user 102 at the selected location 401 in the first scenario 410, is selected, etc. In other embodiments, the information may also indicate, for example, a predetermined distance in the coordinate system of the scene of the target space.
With the acquired information associated with the selection of the transition point, the electronic device 110 may select a target transition point from a plurality of candidate transition points included within the target view area. For example, the electronic device 110 may calculate respective distances between a plurality of candidate transition points within the target view field region and the user 102 selected location 401 in the first scene 410. A target transition point is selected from a plurality of candidate transition points based on a comparison between the distances or based on a comparison between the distances and a given predetermined distance.
As illustrated in fig. 4B, after determining the target transition point, the electronic device 110 may transition from the currently presented first scene 410 to the second scene 420 of the presentation target space.
It is also possible that no transition point capable of triggering a view jump is present within the target view region determined by the electronic device 110, in which case the electronic device 110 may select a transition point adjacent to the position 403 of the camera associated with the scene image acquisition of the first scene 401.
Alternatively or additionally, if there is no transition point capable of triggering view jump in the target view field region determined by the electronic device 110, the electronic device 110 may also present a prompt that there is no candidate transition point in the target view field region or a prompt that recommends the user to update parameters for controlling view transition.
By the scheme, the roaming visual angle of the scene in the target space can be controlled, so that personalized roaming requirements for the target space are met, and user experience is further improved.
