Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to: wireless, wire, fiber optic cable, RF, etc., or any suitable combination of the foregoing.
The technical solution of the embodiment of the present disclosure is explained in detail below:
currently, a live broadcast platform can provide an interface for a user to interact with a main broadcast in real time, and the interface can transmit live broadcast scenes of the main broadcast for the user in real time in a mode of capturing current image data of a screen or a camera. However, in the whole process of watching the live broadcast, the visual angle of the user is limited to the picture displayed by the main broadcast screen, the interaction with the main broadcast is lacked, and the participation sense of the user is reduced. For example, for live broadcasting in a private room, a user can only watch the main broadcasting and live broadcast by using a mobile phone, and the interaction and the participation are not existed.
Based on one or more of the above problems, the present exemplary embodiment provides a live broadcast interaction method, which may be applied to the viewer terminal 104, the anchor terminal 101, the live broadcast server 103 and the central control module 102, and this is not particularly limited in this exemplary embodiment. Referring to fig. 3, the live interaction method may include the following steps S310 to S330:
s310, obtaining map information of a live broadcast area where a main broadcast terminal is located;
s320, generating a position information interaction area on the graphical user interface according to the map information;
step S330, responding to an operation event acting on the position information interaction area, providing a display window on the graphical user interface, and displaying video data corresponding to the position information interaction area in the display window.
In the live broadcast interaction method provided by the embodiment of the disclosure, map information of a live broadcast area where a main broadcast terminal is located is obtained; generating a position information interaction area on the graphical user interface according to the map information; and responding to an operation event acting on the position information interaction area, providing a display window on the graphical user interface, and displaying video data corresponding to the position information interaction area in the display window. Spectators can independently select the live broadcast viewing angle through the position information interaction region while watching the live broadcast picture of the main broadcast, so that the interaction diversity of the live broadcast client is realized, and further the live broadcast viewing experience of spectators is improved.
The above steps of the present exemplary embodiment will be described in more detail below.
In step S310, map information of a live zone where the anchor terminal is located is acquired.
The anchor client can be an anchor live client, the client can be provided with a live application program, when the live application program is running, the live server can acquire current live data captured by the anchor client, namely when the live application program is running, the anchor client can capture a live picture displayed on a current screen and transmit the live picture to an audience client for watching the live picture through the live server. The viewer client may also have a live application installed for viewing live pictures transmitted in real time by the live server.
In an exemplary embodiment, a live broadcast in a closed room may be taken as an example, the live broadcast content in the closed room is different from a live broadcast of games, a live broadcast of gourmet, and the like, and the live broadcast in the closed room refers to a live broadcast mode in which a main broadcast participates in various playing methods and simultaneously the whole process is live broadcast to attract users to watch the live broadcast in a closed space (the closed space may be one room or a combination of multiple rooms). For example, live broadcasting in a secret room can be a main broadcasting and participate in various decryption games, clues and prompts are continuously discovered through observation and logical thinking, the user can leave from the secret room if passing through within a specified time, the whole live broadcasting process is full of unknowns and uncertainty, the user can decrypt with the main broadcasting through watching the live broadcasting, and the interest of watching the live broadcasting is increased for the user.
In this example, a graphical user interface may be provided by the viewer terminal, and a location information interaction area may be displayed on the graphical user interface of the viewer terminal while the live application of the viewer client is running. Before displaying the position information interaction area, map information of a live broadcast area where the anchor terminal is located may be acquired. The map information of the live broadcast area can include a two-dimensional plane map of the live broadcast area, image information collected by a camera device arranged in the live broadcast area and three-dimensional point cloud data of the live broadcast area.
In one example, a two-dimensional plan of a darkroom may be obtained by using a visual SLAM (Simultaneous Localization And Mapping) method, where SLAM refers to a main body carrying a specific sensor (such as a camera or a video camera), And a map or a model of an environment is created during a movement process without environment prior information. In other examples, a two-dimensional plan of the chamber may also be obtained by three-dimensional laser scanning, laser ranging sensor, etc. using a measuring device.
The live broadcast area where the anchor terminal is located may include at least one live broadcast sub-area, and the anchor may be live broadcast in any live broadcast sub-area. For example, in a backroom live broadcast, the live broadcast zone may be a backroom and the live broadcast sub-zone may be a plurality of small backrooms in the backroom. The number of the direct broadcasting sub-areas can be consistent with the number of the small backrooms, and can also be smaller than the number of the small backrooms, namely, the direct broadcasting in the backrooms can not be carried out on part of the small backrooms. The two-dimensional plan of the live broadcast area can comprise information of each live broadcast subarea, so that the distribution of each small backroom in the backroom can be visually shown to audiences through the two-dimensional plan of the backroom.
In one example, image information collected by a camera device disposed in a live broadcast area may be acquired. For example, a plurality of cameras may be provided in the live broadcast area, and at least one camera may be installed in each live broadcast sub-area of the live broadcast area. In this example, a darkroom central control system may be included in the darkroom live broadcast, and the darkroom central control system may collect video data captured by the cameras in each live broadcast subarea in the darkroom, and may also control the activation and reset of the darkroom devices, for example, may control the activation and reset functions of each camera. Therefore, the image information collected by the camera device arranged in the live broadcast area can be acquired in real time through the secret room central control system.
In one example, three-dimensional point cloud data of a backroom may be acquired. For example, three-dimensional coordinates and imagery of a chamber may be acquired using an optical ranging system, which may include stereo cameras, time-of-flight infrared cameras, and structured light devices, or intensity-based scanning techniques.
In step S320, a location information interaction area is generated on the graphical user interface according to the map information.
In this example, the location information interaction area may be a User Interface (UI) of a backroom where the live broadcast is hosted, the map UI provides an accessible and effective visualization method for representing a geographic space reality, and the map UI may further include an interaction relationship between a User and a terminal Interface.
In one example, after a two-dimensional plan of a backroom is obtained, a backroom map UI design may be performed according to the two-dimensional plan, for example, information of each live sub-area in the two-dimensional plan may be mapped on a graphical user interface of a viewer terminal to generate a location information interaction area. Specifically, a map model can be drawn in an equal scale according to the contour of each live broadcast sub-area in the two-dimensional plane map, and when the map model is displayed on a graphical user interface, a backroom map UI can be generated on the graphical user interface. The position information interaction area can comprise at least one interaction sub-area, and the interaction sub-areas correspond to the live broadcast sub-areas one by one.
In another example, after image information acquired by a camera device arranged in each live broadcast sub-area is acquired, an interactive sub-area may be generated according to the image information. In this example, the camera device may be a panoramic camera, such as a 720 degree panoramic camera. The panoramic pictures shot by the panoramic camera arranged in each live broadcast subregion can be acquired in real time, and each panoramic picture is extracted, for example, the picture region extraction can be performed on each panoramic picture from a specified view angle, the extracted picture region is subjected to overlook projection, and a two-dimensional plane projection image of each live broadcast subregion is generated. A plurality of interactive sub-regions may be generated when the two-dimensional planar projection image of each live sub-region is mapped to the graphical user interface. And finally, sequentially splicing and synthesizing the interaction subregions corresponding to the panoramic cameras according to the position distribution of the panoramic cameras in the live broadcast region to generate a position information interaction region.
Referring to fig. 4, when the live application of the user client is running, a backroom map UI 420 may be displayed in the live interface 410 displayed on the viewer terminal, and the backroom map UI 420 may be located at any position in the live interface 410, such as the lower right corner in the live interface 410 or the upper left corner in the live interface 410.
At least one interactive sub-area may be included in the backroom map UI 420 corresponding to a plurality of live sub-areas in the live area. In an example embodiment, each interactive sub-region may be set as a click hot region, the click hot region may function as a button, the click hot region refers to a click region where the button is valid, and each click hot region may represent a small secret room in which a photographing device is installed. As shown in fig. 4, 6 click zones are displayed in the backroom map UI 420, which can easily indicate that the backroom where the anchor is located includes 6 sub-areas, for example, 6 small backrooms. The shape of the click hot zone can be consistent with the shape of each small chamber in the two-dimensional plan of the chamber. In other examples, the shape of the click hot zone may be any shape, such as a circle or other shape containing the center position of each small chamber in the two-dimensional plan view of the chamber, which is not specifically limited in this example. It is noted that the backroom map UI 420 may move through the live interface 410 in response to a viewer action event, such as the backroom map UI 420 may follow the hand identifiers of fig. 4.
In an example embodiment, the location information sent by the anchor terminal may also be acquired, and the location identifier of the anchor terminal is displayed in the location information interaction area. The anchor terminal can be an anchor mobile phone, the anchor mobile phone can be used for normal live broadcasting and can also be used as a position positioning anchor point, position information (such as coordinate information) of the anchor mobile phone in a secret room can be sent to a secret room central control system, and the secret room central control system can send the real-time position information of the anchor mobile phone to audience terminals through a data interface. Correspondingly, an identifier (such as a circle identifier in fig. 4) may be defined in the tight room map UI 420 to represent the anchor and move along with the anchor in the tight room, and the identifier may be used to indicate the corresponding location of the anchor in the tight room, so that the viewer can know the current location of the anchor in the tight room in real time according to the identifier.
Illustratively, the position information of the anchor terminal can be obtained through visual positioning, wherein the visual positioning refers to calculating the position and the posture of a camera when a certain two-dimensional image is shot according to a pre-constructed 3D model. The matching relationship between the 3D point and the 2D point needs to be established so as to estimate the pose of the camera through the matching relationship. For example, video stream data in a dense room including color images, depth images and pose parameters may be acquired, an indoor three-dimensional map and an indoor two-dimensional map may be constructed from the video stream data in the room, and coordinate systems of the indoor three-dimensional map and the indoor two-dimensional map may be matched to construct a network data set. The network data set comprises a color image, a depth image, a pose parameter, an indoor three-dimensional map and an indoor two-dimensional map. Specifically, a current shooting picture of the anchor terminal can be obtained, and based on a pre-constructed network data set, the current shooting picture can be matched with the three-dimensional point cloud data of the live broadcast area to determine a coordinate position of a 2D key point of the current shooting picture in the three-dimensional point cloud data, so as to determine current position information of the anchor terminal in the live broadcast area.
In step S330, in response to an operation event acting on the position information interaction area, a display window is provided on the graphical user interface, and video data corresponding to the position information interaction area is displayed in the display window.
In an example embodiment, the central control system in the secret room can control and start the camera devices of each live broadcast subarea in the secret room, and after the camera devices are started, the corresponding live broadcast subareas can be independently shot. The secret room central control system is connected with each camera device in the secret room and can acquire video data of each live broadcast subarea in real time, and the secret room central control system can send corresponding video data to audience terminals through data interfaces according to operation events of audiences on position information interaction areas.
For example, when the viewer terminal device is a smartphone, the operation event may be a click operation or a press operation, for example, the viewer may touch and click or press the location information interaction area for interaction. When the viewer terminal device is a PC (computer) terminal, the operation event may be a click operation, for example, the viewer may click the location information interaction area through a mouse to perform interaction. When a viewer clicks a first interactive subarea in a backroom map UI, a display window can be generated on a graphical user interface of a viewer terminal in response to the clicking operation, and video data shot by a camera device in a live broadcasting subarea corresponding to the first interactive subarea is displayed in the display window. In one example, in response to a click operation on the first interaction sub-region, the first interaction sub-region may also be displayed in an identifiable manner in the backroom map UI, such as may be displayed in a highlighted form, a bolded form of an outline of the interaction sub-region, or other forms.
Referring to fig. 5, when the viewer clicks on any one of the hot click zones in the backroom map UI 420, the hot click zone may be distinctively displayed on other hot click zones, such as by highlighting them. Meanwhile, a display window 430 is generated on the live interface 410, and the video data of the backroom area corresponding to the clicked hot area is displayed through the display window. The display window 430 may be displayed on the live interface, for example, the display window 430 may cover one third of the area of the live interface, or the viewer may manually adjust the size of the display window according to actual needs, which is not limited in this example. In this example, it is convenient for the viewer to operate the display window and view video data in any area of the live broadcast area where the anchor is located, and the convenience of use of the viewer terminal is improved.
In the method, a visual interactive map interface (namely a secret room map UI) is displayed for the audience, so that the audience can quickly know the regional distribution of the secret room, and the audience can also master the current position of the anchor in the secret room in real time. In addition, the audience can interactively watch different areas in the backroom by clicking the interactive subarea in the backroom map UI, and the participation sense of the audience is increased by interactively watching live broadcast.
As shown in fig. 6, video data presentation may also be performed according to steps S610 and S620.
In step S610, a target display area of the display window on the graphical user interface is determined according to a relative positional relationship between the position identifier of the anchor terminal and the first interaction sub-area.
And responding to an operation event of the audience to the first interaction sub-region in the position information interaction region, and determining a target display region of the display window on the client interface according to a relative position relation between the position identifier of the anchor terminal in the position information interaction region and the first interaction sub-region, namely, the up-down left-right relation between the anchor and each secret room region.
In step S620, the video data captured by the camera in the live broadcast sub-area corresponding to the first interactive sub-area is displayed in the target display area through the display window.
Illustratively, the darkroom area corresponding to the first interaction subregion is an a darkroom, and as can be known from a darkroom map UI, it is assumed that the anchor is located at the upper left of the a darkroom at the current moment, that is, the a darkroom is located at the lower right of the current position of the anchor, so that it can be determined that the current target display area of the display window is located at the lower right area of the live broadcast interface, and a real-time video picture in the a darkroom can be played through the display window, and the video picture is captured by a camera device in the a darkroom in real time. In other examples, the display window may also be displayed at a fixed position of the live interface, for example, the display window may be fixedly located at a lower right corner of the live interface, so as to avoid the display window from blocking the live interface, and optimize the user experience.
In an example embodiment, the operation event may be taken as a click operation as an example, first, whether a click operation is received at any position in the backroom map UI may be detected, and when the click operation is detected, a position range of the click operation may be determined by a position sensor to determine whether the click operation acts on any position of any interactive sub-region. When an operation event acting on the second interaction sub-region is detected, the video data corresponding to the first interaction sub-region in the display window can be replaced by the video data corresponding to the second interaction sub-region. In other examples, a plurality of display windows may be correspondingly generated on a graphical user interface of the viewer terminal in response to a plurality of operation events that the viewer acts on the location information interaction area, which is not specifically limited in this example. For example, when the viewer sequentially clicks two interactive sub-regions, two display windows may be sequentially generated on the graphical user interface, and video data corresponding to each interactive sub-region may be displayed in each display window.
Referring to fig. 7, in the backroom map UI 420 shown in fig. 7A, the highlighted circle identification may represent the current location of the anchor and the highlighted square identification may represent a first interaction sub-area, such as a first click zone, corresponding to a small backroom a in the backroom. Moreover, since the small cell a is located at the lower right of the current position of the anchor, the display window 430 may be displayed at the lower right corner of the live interface 410, and the video data displayed in the display window 430 may be captured by the camera device in the small cell a in real time. In the backroom map UI 420 shown in fig. 7B, the current location of the anchor has not changed, and when the viewer clicks on a second interactive sub-region, such as a second click hot region, the second click hot region may be highlighted, and at the same time, the highlighting of the first click hot region is cancelled. The second click hot zone corresponds to a small secret room B in the secret room, the display window 430 can be displayed in the upper left corner of the live interface 410 according to the relative position of the small secret room B and the anchor, and the video data displayed in the display window 430 can be obtained by real-time shooting through a camera device in the small secret room B. In this example, according to the relative position relationship between each small secret room of the secret room and the anchor, the video data in the region can be displayed at the corresponding position in the live broadcast interface, and a coherent visual effect can be achieved when a user watches the scene change of the secret room.
According to the live broadcast interaction method, the backroom central control system can transmit anchor position information and backroom map information with the live broadcast client in real time, audiences can visually know the current backroom condition and the position of the anchor from the on-line mode, and video pictures shot by the corresponding camera device can be automatically displayed on live broadcast pictures according to the interaction of the backroom map UI on the live broadcast interface. Meanwhile, the anchor and the audience can realize the interaction between the online and the offline, and the live broadcast effect is improved.
In an example embodiment, when an operation event acting on a third interaction sub-region where a anchor terminal is located in a location information interaction region is detected, a target live broadcast sub-region corresponding to the third interaction sub-region may be determined. Similar to the generation process of the position information interaction area, the map information of the target live broadcast sub-area can be acquired, and the target information interaction area is generated according to the map information of the target live broadcast sub-area. Meanwhile, the position information interaction area can be updated to be the target information interaction area on the live broadcast interface. The target information interaction area can be used for showing the layout of the target live broadcast subarea, for example, the target information interaction area can contain the distribution of each area in the target live broadcast subarea, and can also contain the item information in the target live broadcast subarea, such as an item identifier, and audiences can know the position of an item through the item identifier so as to interact with the anchor. Referring to fig. 8, in fig. 8A, when the location identification of the anchor is located in the interactive sub-area 810, it corresponds to the anchor being located in the cell corresponding to the interactive sub-area 810 at this time. Illustratively, when the audience clicks the interaction sub-area 810, information of a corresponding small secret room can be acquired, and meanwhile, the secret room map UI can be changed, that is, the secret room map UI can be updated to the map UI of the small secret room, distribution of each area in the small secret room can be visually shown to the audience through the map UI of the small secret room, and position information of each article in the small secret room can also be shown to the audience.
