The flow charts shown in the drawings are merely illustrative and do not necessarily include all of the steps. For example, some steps may be decomposed, and some steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.
With the continuous improvement of living standard of people, people watching live broadcast are more and more, and the live broadcast mode is continuously developed.
The live broadcast mode can be live broadcast in a real scene only by the original anchor, and the anchor can select live broadcast in the real scene or live broadcast in a virtual scene according to live broadcast content and live broadcast requirements at present.
Live broadcast is carried out in a real scene, and due to the fact that available live broadcast scenes of a main broadcast are limited or live broadcast is carried out in the same live broadcast scene for a long time, the live broadcast scene is single, and the condition that users are lost easily occurs. Live broadcast under the virtual scene can change the live broadcast scene according to the live broadcast content, thereby increasing the diversity of the live broadcast scene and further improving the retention rate of users.
However, the related live broadcast technology in the virtual scene has the problems of incomplete extraction of the anchor portrait, poor fusion effect of the virtual scene and the anchor portrait, and the like. For example, when a plurality of portraits exist in a real scene, the anchor portraits cannot be accurately extracted; when the content in the virtual scene is rich, the optimal position in the virtual scene where the anchor portrait can be fused cannot be determined. In view of this, a new live broadcasting method is needed.
The respective steps of the object detection method of the exemplary embodiment of the present disclosure may be generally performed by a server, in which case the object detection apparatus described below may be configured within the server. The server may include a dedicated chip or be equipped with an independent GPU (Graphics Processing Unit). However, aspects of the present disclosure may also be implemented with terminal devices, which may include, but are not limited to, cell phones, tablets, personal computers, and the like.
Fig. 1 schematically shows a flow chart of a live method of an exemplary embodiment of the present disclosure. Referring to fig. 1, the live broadcasting method may include the steps of:
and S12, acquiring virtual scene information by adopting a first process.
In an exemplary embodiment of the present disclosure, the first process may be a scenario process. The virtual scene information may include a virtual scene, in an optional embodiment, the virtual scene information may include a virtual scene and a virtual object, in an optional embodiment, the virtual scene information may include a virtual scene and a scene audio, and in an optional embodiment, the virtual scene information may include a virtual scene, a virtual object and a scene audio; specifically, the virtual scene can be a scene background such as a tall building, a sea wave beach, a yellow river shoreside and the like; the virtual object can be scene decorations such as love balloons, aircraft rockets, space vehicles and the like; the scene audio can be the sound effect and the background music carried by the virtual scene. In an exemplary embodiment of the present disclosure, before loading the virtual scene with the first process, the scene parameters need to be determined according to the preselected scene objects. Loading a designated virtual scene according to a preselected scene object, wherein a program for loading the virtual scene can be developed through an existing rendering engine; the specified virtual scene may be one of a plurality of virtual scenes designed in advance; the preselected scene object can be preselected by a main player, preselected by a viewer (such as a scene object determined by most numbers or characters input by a bullet screen), or preselected by a system (such as a scene object randomly determined by a system turntable); the scene object may be a parameter set in the rendering engine, or may be a picture selected by a host, and the like, and each set of the parameter or each preselected picture corresponds to one virtual scene. It should be noted that the virtual scene in the present disclosure may be a two-dimensional virtual scene, and may also be a three-dimensional virtual scene.
Specifically, referring to fig. 2, when the preselected scene object 21 is a picture, the picture may be identified by using a machine learning model to obtain a scene parameter 23, where the machine learning model may be a convolutional neural network model, and the type and parameters of the model are not particularly limited by the present disclosure; the scene parameters 23 include elements 25 such as style, location, color system, etc. of the content in the picture; from this set of elements 25 a virtual scene 27 is determined corresponding thereto.
S14, acquiring real scene information determined by a second process by adopting the first process, and extracting anchor portrait information from the real scene information;
in an exemplary embodiment of the present disclosure, the second process is responsible for acquiring video and/or audio information in a real scene in real time, and sending the video and/or audio information to the first process in a memory sharing manner, where the second process and the first process perform different actions. The second process may be a live process in this disclosure. The real scene information includes: anchor portrait information, anchor audio information. It should be noted that one or more of the two kinds of information may be collected through the second process, and the specific collection of several kinds of information is determined according to the requirements of the anchor live broadcast. The real scene information acquisition device is a device capable of acquiring video and audio, and includes but is not limited to a camera, a microphone, and the like. The anchor portrait information is the body of the anchor that appears in the real scene. For example, the camera only shoots the live face, and the anchor portrait information is the anchor face information; the camera shoots the face and the arms of the anchor, and the portrait information of the anchor is the face and the arms of the anchor at the moment; the anchor audio information is the sound of the anchor in the live broadcasting process of the real scene, and comprises the sound collected by a microphone, the played background music and the like.
In an optional embodiment, the first process and the second process belong to the same live broadcast client (live broadcast client software/live broadcast client application), and further, the first process and the second process run in the same electronic device, where the live broadcast client runs in the electronic device, and the electronic device is a device used by an anchor user for live broadcast, such as a mobile phone, a personal computer, and the like.
In an exemplary embodiment of the present disclosure, the first process is adopted to obtain the real scene information determined by the second process, the anchor portrait is detected from the information in the real scene, and the anchor portrait is separated from the background in the real scene to obtain the anchor portrait information. Specifically, the detection method may use an image recognition method.
In this embodiment, only one person may be live in the video frame of the real scene, or a plurality of persons may exist in the frame. Under the condition that only one anchor person exists in the picture, the area where the anchor portrait is located can be detected through an image recognition method, and then the area where the anchor portrait is located is separated from the background, so that the anchor portrait information can be obtained. When there are multiple people in the picture, the anchor portrait needs to be separated from the multiple portraits.
Fig. 3 schematically shows a flow diagram of extracting a anchor portrait from multiple portraits of a real scene in the present disclosure. Referring to fig. 3, when a plurality of human figures 33 are detected from a real scene 31, the plurality of human figures 33 are separated from the background, similarity calculation is performed on the separated human figures 33 and pre-stored anchor human figures respectively, and the human figure with the highest similarity is extracted as anchor human figure information 35. The similarity calculation method comprises the following steps: training the anchor portrait in advance through a neural network by using a machine learning method, then respectively inputting the detected portrait into the trained neural network for image recognition, and then outputting the similarity that the image is the anchor portrait; when the input image is the anchor portrait, the similarity obtained through the calculation of the neural network is far higher than that when the input image is not the anchor portrait, and the portrait with the highest similarity is the anchor portrait.
And S16, fusing the virtual scene information and the anchor portrait information by adopting the first process to generate live broadcast data.
In an exemplary embodiment of the present disclosure, live data refers to data obtained by fusing a virtual scene with anchor portrait and/or audio information.
Fig. 4 schematically illustrates a flow chart fusing anchor portrait, virtual scene, and audio information according to an exemplary embodiment of the present disclosure. Referring to fig. 4, a live broadcast portrait 401 is fused with a virtual scene 403 through a first process to obtain a live broadcast picture, and preferably, the live broadcast picture may be sent to a second process in a texture sharing manner; optionally, the audio information 405 may also be fused into a live broadcast picture to generate live broadcast data 411; specifically, a first process is adopted to obtain a scene audio 407, and the scene audio is sent to a second process in a memory sharing manner; acquiring a main broadcasting audio 409 through a microphone by adopting a second process, and mixing the scene audio 407 and the main broadcasting audio 409 in the second process to generate a live broadcasting audio; finally, in the second process, the live broadcast picture and the live broadcast audio are fused to generate live broadcast data 411. Optionally, after generating the live data 411, the live client sends the live data 411 to the live server, so that the live server provides the live data 411 to the live viewer client.
It should be noted that the method in the above embodiment is only an optional solution. The process of fusing the anchor portrait and the virtual scene in the disclosure can be realized in a first process and can also be realized in a second process; the process of generating live audio in the present disclosure may be implemented before, after, or simultaneously with the process of generating a live view; the inter-process data transmission mode is various, and other modes are used for inter-process data transmission to achieve the result achieved by the disclosure, which also belongs to the scope of the inventive content in the disclosure.
In an exemplary embodiment of the present disclosure, before the virtual scene is fused with the anchor portrait and/or the audio information, the position of each virtual object in the virtual scene information is determined first, then a target area of the anchor portrait in the virtual scene is determined according to the position of each virtual object, and finally the anchor portrait is configured in the target area. Specifically, by a target detection method in machine learning, which virtual objects exist in a virtual scene and the positions of the virtual objects in the virtual scene are detected, the position where the anchor portrait is most suitable to be placed is judged, and the anchor portrait is configured at the position. For example, a sea is in the virtual scene, a boat is in the sea, and after the sea and the boat in the virtual scene are detected, it is judged that the boat is more suitable for placing the anchor portrait, that is, the anchor portrait is configured at the position of the boat.
In another embodiment of the disclosure, when the size of the extracted anchor portrait does not accord with the size of a target area of the anchor portrait to be configured in the virtual scene, adjusting the size of the anchor portrait according to the size of the target area to obtain an adjusted anchor portrait; and configuring the adjusted anchor portrait in a target area, namely rendering the anchor portrait to an appointed patch to obtain a live broadcast picture.
In another embodiment of the present disclosure, the anchor portrait may be rendered in a customized tile by a rendering engine, and specific material parameters are configured on the tile according to the characteristics of the anchor portrait, so as to achieve the best fusion effect. Optionally, effects such as illumination can be automatically superimposed on the live broadcast picture through the rendering engine, so that the fusion effect of the characters and the scene is further improved.
In another embodiment of the present disclosure, the generated virtual live view may be previewed in advance. The anchor can select a proper virtual scene for live broadcasting according to the effect of the virtual live broadcasting. For example, before a virtual scene is selected by a anchor, a live broadcast effect in the virtual scene may be watched at a live broadcast end, and at this time, a user cannot see a picture of the anchor in the virtual scene. And when the anchor determines that the live broadcast is carried out in the scene, taking the picture in the virtual scene as a live broadcast picture.
In another embodiment of the present disclosure, when the user presents the virtual gift to the anchor, a corresponding virtual object is added in the live broadcast picture according to the type of the virtual gift, and the virtual object can also be added in the live broadcast picture according to the live broadcast habit of the anchor. For example, when a user gifts a balloon to a anchor, a balloon effect having a love shape may be generated in a live view.
Fig. 5 schematically shows an effect diagram of the live broadcasting method in the present disclosure. When the anchor is live at some festivals, the live broadcast can be performed in a virtual scene with a festival atmosphere using the method of the present disclosure. Referring to fig. 5, when the anchor is broadcast directly at the valentine's day, the anchor can be selected to broadcast directly under the background of a plurality of hearts formed by pink balloons, so that the festival atmosphere can be increased, the live broadcast effect can be improved, and the user can be attracted more. When a user gives a gift to the anchor, different scene objects, such as an orange flash balloon, a red rose and the like, can be triggered on a pink heart background according to the type of the gift.
The live broadcast method of the present disclosure will be further explained with reference to fig. 6.
Fig. 6 schematically shows a flow chart for implementing a live method using two processes. In step S601, a specified virtual scene is loaded using a first process. In the embodiment of the disclosure, the first process may be a scene process, which is a scene loader built based on a rendering engine bottom layer, and different scene resources may be loaded and run according to an instruction. In step S603, the real scene data is monitored using the second process. In the embodiment of the present disclosure, the second process may be a live broadcast process, and when the live broadcast process receives a live broadcast instruction, a scene process is started, and the scene process loads a specific scene according to a specific parameter. In step S605, the second process sends the video data in the real scene to the first process by using the memory sharing method, and the first process separates the anchor portrait from the background in the video data by using step S607 to obtain the anchor portrait. In step S609, the anchor portrait is fused with the virtual scene to obtain a live broadcast picture; in the fusion process, a position which is most suitable for configuring the anchor portrait needs to be found in the virtual scene in advance, the size of the anchor portrait is adjusted according to the area size of the position, and the adjusted anchor portrait is configured at the optimal position. In step S611, the first process transmits the live view to the second process by sharing the texture. In step S613 and step S615, the first process and the second process are respectively adopted to obtain the scene audio in the virtual scene and the anchor audio in the real scene, and then the first process sends the scene audio to the second process in a memory sharing manner through step S617. In step S619, a second process is used to mix the scene audio with the anchor audio to obtain live audio. In step S621, a second process is used to fuse the live broadcast picture and the live broadcast audio to obtain live broadcast data.
