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 shown in the 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 terms "first," "second," and the like may refer to different or the same objects. Other explicit and implicit definitions are also possible below.

The distributed shooting system may include a shooting array composed of at least two shooting devices, the shooting devices may shoot images or videos, the shooting devices may be referred to as image capturing devices, and the like, and the distributed shooting system may also be referred to as a distributed camera system or a distributed shooting array or a distributed image capturing system, and the like. It is to be understood that the "image" in the embodiment of the present disclosure may be an image captured by a capturing device or may be a frame of a video captured by an image capturing device. In addition, video may also be referred to as an image stream, a frame stream, a video stream, a media stream, and so on, and the disclosure is not limited thereto.

At least two shooting devices in the distributed shooting system can shoot simultaneously to acquire more visual information, and then multi-path images can be displayed on the same screen, spliced in real time and the like through mutual cooperation. The distributed photographing system may be implemented in various different scenarios. For example, a distributed camera system may be implemented as a look-around camera array, where multiple cameras may be arranged at certain angles and intervals around a target object, and each camera is responsible for taking a picture of the target object in a certain field of view, so that when images taken by the respective cameras are played in sequence, the target object is viewed from different angles along an arc in one direction as if the human eye were centered on the target object.

The distributed shooting system is also applied to live webcasting. In a live network scene, multiple shooting devices of the distributed shooting system can respectively shoot, and the anchor can select videos to be presented so that customers can view the videos through the client devices. In this process, the content viewed by the patrons is determined by the anchor, i.e., the client devices are only passive recipients of the video, resulting in all of the patrons viewing the live content from the respective different clients to be identical. Even if the anchor does not switch the shooting devices, the video shot by other shooting devices in the distributed shooting system is wasted, and the videos shot by a plurality of shooting devices cannot be fully utilized. Thus, the experience and feeling of watching the live broadcast are seriously influenced.

In view of this, the present disclosure provides a video presentation scheme, where a client device may receive a composite video obtained from videos shot by multiple shooting devices, and perform local presentation based on the composite video, so that different requirements of different users for presentation can be met, and user experience is improved.

FIG. 1 illustrates a schematic diagram of an example environment 100 in which embodiments of the present disclosure may be implemented. In the example environment 100, a central device 110, a distributed camera system 120, a client device 130-1, a client device 130-2, \ 8230, and a client device 130-N are shown. Distributed camera system 120 includes multiple cameras, such as camera 122-1, camera 122-2, and camera 122-3 in FIG. 1.

For convenience of description below, the photographing device 122-1, the photographing device 122-2, and the photographing device 122-3 are collectively referred to as the photographing device 122 in the embodiments of the present disclosure, and the client device 130-1, the client device 130-2, \ 8230, and the client device 130-N are collectively referred to as the client device 130 in the embodiments of the present disclosure. And it is understood that although it is illustrated in fig. 1 that the distributed photographing system 120 includes three photographing apparatuses, in an actual application, the number of photographing apparatuses included in the distributed photographing system 120 may be set according to a scene or the like. The photographing device 122 may be a stand-alone device or may be a peripheral of other electronic devices, for example, the photographing device 122 may be implemented as an electronic device having an image capturing function, and the like. The capture device 122 may include a camera, a camcorder, a snap-shot device, a cell phone, a tablet, a wearable device, etc., to which the present disclosure is not limited.

As shown in fig. 1, the center device 110 may interact with the client devices 130, and in a scenario such as webcast, the center device 110 may be an electronic device that interacts with a host and the client devices 130 may be electronic devices that interact with a user. That is, the center device 110 has a communication connection with the client device 130.

In some embodiments, the hub device 110 may interact with the client devices 130 via a server (e.g., a streaming media server). In some embodiments, the central device 110 and the client devices 130 may be implemented as electronic devices such as smartphones, tablets, wearable devices, and the like. Embodiments of the present disclosure do not limit the number (N) of client devices, for example in a live webcast scenario, the number of client devices may be on the order of hundreds, tens of thousands, or even greater.

As shown in FIG. 1, central facility 110 may interact with distributed camera system 120, for example, images or videos taken by camera 122-1, camera 122-2, and camera 122-3, respectively, may be transmitted to central facility 110.

The center device 110 and the shooting device 122 may have a communication connection therebetween, and the embodiment of the disclosure does not limit the connection manner, for example, the connection is performed in a wired or wireless manner. Wired means may include, but are not limited to, fiber optic connections, universal Serial Bus (USB) connections, etc., and wireless means may include, but are not limited to, mobile communication technologies (including, but not limited to, 2g,3g,4g,5g,6g, etc., wi-Fi, bluetooth (Bluetooth), point-to-Point (P2P), etc.).

Taking a Wi-Fi connection as an example, the center device 110 and the photographing device 122 may be in the same local area network environment, and the center device 110 may discover the photographing device 122 located in the same local area network environment through its distributed photographing system control module (or a connection discovery module or other modules, etc.), and establish a Wi-Fi connection with the photographing device 122, for example, the center device 110 and the photographing device 122 may be connected to the same router. It should be noted that the communication connection between the center device 110 and the different photographing devices 122 may be the same or different. For example, the center apparatus 110 and the photographing apparatus 122-1 may be connected in a different manner from the center apparatus 110 and the photographing apparatus 122-2.

Although the central device 110 is shown in fig. 1 as a device separate from the distributed camera system 120, in some embodiments, the central device 110 may be implemented as part of the distributed camera system 120, e.g., the central device 110 may be an electronic device to which the camera device 122-2 corresponds.

The embodiment of the present disclosure does not limit the arrangement manner of each shooting device in the distributed shooting system 120.

In some embodiments, the photographing apparatus 122-1, the photographing apparatus 122-2, and the photographing apparatus 122-3 may be arranged side by side so that photographing directions of the target objects are parallel or substantially uniform when photographing the target objects.

In some embodiments, the photographing apparatus 122-1, the photographing apparatus 122-2, and the photographing apparatus 122-3 may be arranged around the target object so as to make an angle with respect to a photographing direction of the target object when photographing the target object. In connection with fig. 2, assume that the distributed photographing system 120 includes 7 photographing devices, respectively photographing devices 122-1 to 122-7, and an electronic device corresponding to the photographing device 122-4 is the center device 110.

In the scene 200 shown in fig. 2, 7 photographing apparatuses may be mounted on the fixed stand 201, and each of the 7 photographing apparatuses may perform image photographing on the target object 202. In a scenario such as a webcast, the target object 202 may be an item to be displayed by the anchor.

In fig. 2, the fixing bracket 201 is implemented as a ring bracket, and a plurality of fixing buckles are provided on the fixing bracket 201 for fixing a plurality of photographing apparatuses 122. And after the plurality of photographing devices 122 are respectively mounted on the fixed support 201, the position and angle of each photographing device 122 with respect to the center of the fixed support 201 (e.g., the center of a circle on which the ring is located) may be fixed. It is to be understood that although the plurality of photographing devices 122 in fig. 2 may photograph toward the center of the fixing bracket 201, that is, the target object 202 is located near the center of the fixing bracket 201. However, the embodiment of the present disclosure is not limited thereto, and for example, the plurality of photographing apparatuses 122 may photograph toward the outside of the fixed stand 201, which can enlarge the field of view to perform a panoramic live broadcast.

In some embodiments, each of the 7 capturing devices in fig. 2 may be implemented as a camera on a smart terminal, for example, in case the smart terminal is a mobile phone, 7 mobile phones may be installed at corresponding positions of the fixing bracket 201. In one embodiment, 7 photographing apparatuses are respectively mounted on the fixing brackets 201, so that photographing angles at which the 7 photographing apparatuses photograph the target object 202 are fixed, i.e., each photographing apparatus is not movable and rotatable. In some embodiments, the angle between the centerlines of each two adjacent cameras may be fixed, for example, the angle may be set to 20 ° or other value.

In the embodiment of the present disclosure, the shooting areas of two adjacent shooting devices in the distributed shooting system 120 may have partial overlap. For example, the photographing device 122-1 photographs the target object 202 to obtain a first image, the photographing device 122-2 photographs the target object 202 to obtain a second image, and the first area in the first image and the second area in the second image are for the same photographing area of the target object 202. In one example, the first area occupies 1/4 or more of the first image and the second area occupies 1/4 or more of the second image.

The embodiment of the disclosure can be applied to the scene of network live broadcast. For live webcasts, the anchor may prepare and fix the various cameras 122 in advance to form a distributed camera system. A plurality of photographing apparatuses 122 are mounted on the fixing bracket 201, for example, in a manner as shown in fig. 2. The anchor may also select the center device 110, for example, setting the electronic device corresponding to the photographing device 122-4 as the center device 110. The anchor may then create a live room through the hub device 110, for example by connecting to a server of a live platform through the hub device 110 to create a live room. The central device 110 may request a server of the live platform to obtain a stream pushing address, such as a Uniform Resource Locator (URL). The push streaming may be a process of the central device 110 pushing the audio and video stream to a server of the live platform, and the push streaming address is an address corresponding to the push streaming process, and a format and the like of the push streaming address depend on a protocol and the like used. Similarly, the client device 130 may obtain the corresponding audio/video stream from the server of the live platform through a pull stream address corresponding to the push stream address, where the pull stream may be a process in which the client device 130 pulls the audio/video stream on the server of the live platform to the local, and the pull stream address is an address corresponding to the pull stream process, and a format of the pull stream address depends on a protocol used, and the like. It will be appreciated that the number of client devices 130 connected to the central device 110 may vary with the customer's entry or exit from the live room.

It will be appreciated that the client device 130 may be caused to establish a communication connection with the central device 110 by a user entering a live room operation. In some embodiments, the hub device 110 may send the live room information to the client device 130. In some embodiments, the client device 130 may send an information request to the live platform server to obtain live room information from the central device 110.

Illustratively, the live room information may include system information of the distributed shooting system. In some embodiments, the system information of the distributed photographing system may include the number of photographing devices included in the distributed photographing system. For example, in the scenario shown in fig. 2, the number is 7. In some embodiments, the system information of the distributed photographing system may include sizes, such as width and height, of images photographed by the respective photographing apparatuses. For example, if the images captured by the respective photographing apparatuses are equal in size, w and h may be included to respectively represent the width and height of the image captured by a single photographing apparatus. In some embodiments, the system information of the distributed camera system may include an identification of the camera device associated with the central device 110. For example, in the scenario shown in fig. 2, the center device 110 is an electronic device corresponding to the camera device 122-4, and the identification of the camera device associated with the center device 110 may be 4. It is understood that the system information of the distributed photographing system may further include other information, etc., such as the resolution of the photographing apparatus, etc., which are not listed one by one here.

Illustratively, the live room information may also include a pull address for the client device 130, through which the client device 130 may retrieve the video. It will be appreciated that live room information may also include other information, etc., such as live room address, live play time, etc., which are not listed here.

Fig. 3 shows a schematic interaction diagram of a video presentation process 300 according to some embodiments of the present disclosure. The process 300 shown in fig. 3 involves the hub device 110 and the client device 130.

In process 300, the center device 110 determines 310 a composite video based on a plurality of videos respectively captured by a plurality of capture devices 122 of the distributed capture system 120.

Exemplarily, the process of determining the composite video by the center device 110 may be as shown in fig. 4, and fig. 4 shows a schematic flow chart of a process 400 of determining the composite video by the center device 110.

In process 400, capture device 122 performs video capture 410. Taking 3 cameras as an example, it can be assumed that camera 122-1 captures video 1, camera 122-2 captures video 2, and camera 122-3 captures video 3.

Alternatively or additionally, the central device 110 and the capture device 122 may be time synchronized 402. The embodiments of the present disclosure do not limit the specific manner of time synchronization. In some embodiments, through time synchronization, time synchronization information between the local clock of the center apparatus 110 and the local clock of the photographing apparatus 122 may be determined. In some embodiments, after time synchronization, different capture devices 122 may take images at the same time. For example, the i-th frame photographed by the photographing device 122-1 and the i-th frame photographed by the photographing device 122-2 are simultaneously acquired.

In process 400, the capture device 122 sends 420 the captured video to the hub device 110. Taking 3 shooting devices as an example, the center device 110 can acquire video 1, video 2, and video 3.

Alternatively or additionally, the hub device 110 may pre-process 422 the video from the capture device 122. In some embodiments, the pre-processing may be for a portion of the video or the entire video. In some embodiments, the pre-processing may include, but is not limited to: beautifying, watermarking, mosaic printing and the like. As an example, watermarking may include adding all or part of the following information over part or all of the frames of the video: the name of the anchor, information of the target object, the identification of the photographing device 122, and the like.

In process 400, the hub device 110 obtains 430 a composite video. Taking 3 shooting devices as an example, the center device 110 may synthesize video 1, video 2, and video 3 to obtain a composite video.

In an embodiment of the present disclosure, the ith frame of the composite video may be obtained based on the ith frame captured by the capturing device 122. In some embodiments, the ith frame captured by each capture device 122 may be combined to obtain the ith frame of the composite video. i is any positive integer, so that the composite video can be obtained by obtaining each frame of the composite video.

In some embodiments, the ith frame captured by each of the capture devices 122 may be stitched in the order of the capture devices 122 to obtain the ith frame of the composite video. For example, assume that the ith frame captured by each of the capturing devices 122 has the same size, e.g., w width and h height. The width of the ith frame of the composite video may be equal to the sum of the widths of the ith frames captured by the respective capture devices 122, and the height of the ith frame of the composite video is higher than h. In some embodiments, the order of the capture device 122 may be: the order of photographing devices arranged in the clockwise direction with the target object 202 as a reference. With reference to fig. 2, taking the target object 202 as a central point, the clockwise sequence of the photographing apparatus 122 is: capture device 122-1, capture device 122-2, capture device 122-3, capture device 122-4, capture device 122-5, capture device 122-6, and capture device 122-7.

For simplicity of description, a process of obtaining a composite video is described taking 3 photographing devices as an example. Specifically, frames in the video 1 captured by the capture device 122-1 are denoted as f11, f12, \8230;, and f1n, frames in the video 2 captured by the capture device 122-2 are denoted as f21, f22, \8230;, and f2n, and frames in the video 3 captured by the capture device 122-3 are denoted as f31, f32, \8230;, and f3n. Then the 1 st frame of the composite video may be f11, f21, and f31 sequentially stitched, \ 8230, and the nth frame of the composite video may be f1n, f2n, and f3n sequentially stitched, as shown in fig. 5.

In other words, the center device 110 may take first frames from the plurality of videos respectively in the order of the photographing device 122 from the corresponding videos, and after finishing taking the first frames of all the videos, splice the plurality of first frames in the order of the photographing device 122 as the first frame of the composite video. Then, the center device 110 may take the second frames from the plurality of videos respectively in the order of the shooting device 122, and after finishing taking the second frames of all the videos, splice the plurality of second frames in the order of the shooting device 122 to obtain the second frame of the composite video. And circulating the steps to obtain the composite video.

It is understood that the above embodiments are only illustrative of the manner in which the composite video is obtained, and the embodiments of the present disclosure are not limited thereto. For example, the composition may be in a reverse order of the photographing apparatus 122, or may be in an order according to other predetermined rules. For example, the splicing may be performed in the width direction or in the height direction, or may be performed in another manner.

In process 300, the hub device 110 sends 320 the composite video to the client device 130.

In some embodiments, the client device 130 may retrieve the composite video via a streaming server by pulling a streaming address.

In some embodiments, the hub device 110 may encode, compress, encapsulate, etc. the composite video before transmitting to the client devices 130. Illustratively, video compression techniques such as h.264 may be employed for the encoding compression. Illustratively, the video may be packaged into a streaming media format such as FLV or TS. Therefore, the requirements for network bandwidth and the like can be reduced, the transmission rate is improved, and the real-time performance is ensured.

Accordingly, client device 130 may determine the composite video by decapsulating, decoding decompression, and the like. In some embodiments, the client device 130 may obtain the encapsulated FLV or TS formatted video data by pulling from the live platform server, and may then obtain the encoded compressed video data by parsing, etc. Further, the client device 130 may operate by decoding to restore the composite video.

In process 300, the client device 130 determines 330 a video to present, wherein the video to present is associated with at least one capture device 122. Further, the client device 130 renders 340 the video to be rendered.

In the embodiment of the present disclosure, presenting a video may refer to displaying frames of the video frame by frame, or may be understood as playing the video.

In some embodiments, the video to be presented may be a composite video. Since one frame of the composite video includes images captured by the respective capturing devices in the distributed capturing system, images taken by the plurality of capturing devices about the target object 202 can be presented at the client device 130 at the same time. In this way, the user at the client device 130 can see images of the target object 202 from various angles at the same time, which can facilitate subsequent selection by the user, such as viewing a video for which capture device.

In some embodiments, the video to be presented may be a video captured by a particular capture device in a distributed capture system. Specifically, a portion photographed by a specific photographing apparatus may be separated from each frame of the composite video, thereby determining a video to be presented. In the embodiment of the present disclosure, the specific photographing apparatus may be any one of: a photographing device located at a target position, a photographing device designated by a user of the client device 130, and the like.

In some embodiments, the target location may be the center device 110, and the video to be presented may be a video captured by a capturing device corresponding to the center device 110. Illustratively, the photographing apparatus corresponding to the center apparatus 110 may be a photographing apparatus included in the center apparatus 110.

For simplicity, the photographing apparatus corresponding to the center apparatus 110 may be referred to as a center photographing apparatus. In some embodiments, the client device 130 may separate the video to be rendered corresponding to the central capture device from the composite video based on the number of multiple capture devices in the distributed capture system (assumed to be M) and the identification of the central capture device (assumed to be p).

For example, if the composite video is determined in a manner similar to stitching as shown in FIG. 5. Then, for any frame of the composite video (i-th frame is assumed), a portion having a width of [ (p-1) × w, p × w ] may be cut out from the i-th frame of the composite video as the i-th frame of the video to be presented. For another example, the ith frame of the composite video may be split into M images, that is, the images captured by the M capturing devices are recovered, and then the image captured by the central capturing device is determined from the M images.

Since the hub device 110 is typically an electronic device operated by the anchor, in this way, the rendered video at the client device 130 can be made consistent with the content on the hub device 110 that the anchor interacts with. Particularly when the anchor makes a voice introduction to the target object 202, the user can be enabled to view the specific details introduced by the anchor in time.

In some embodiments, the target location may be an intermediate location of the plurality of capture devices, and the video to be presented may be a video captured by a capture device located at the intermediate location in the distributed capture system. Assume that the number of a plurality of photographing apparatuses in the distributed photographing system is M. Then if M is an odd number, the number of the photographing apparatus located at the middle position is (M + 1)/2. If M is even, the number of the photographing apparatus located at the middle position may be M/2 or M/2+1.

In this way, the image of the front side of the target object 202 can be viewed by the user at the client device 130, enabling the user to view more details of the target object 202.

In some embodiments, the video to be presented may be a video captured by a user-specified capture device. Specifically, the client device 130 may receive an input instruction of the user, which may indicate which photographing device of the plurality of photographing devices.

For example, the user may input a photographing apparatus number, such as "2", so that the client apparatus 130 can acquire the input instruction. For example, during the process that the client device 130 is playing a video shot by a certain shooting device (assuming the number n 1), the user can determine the shooting device number by sliding left or right. For example, a left slide indicates that the photographing apparatus number is reduced by one, i.e., the photographing apparatus number is designated as n1-1. For example, a right slide indicates that the photographing apparatus number is increased by one, i.e., the photographing apparatus number is designated as n1+1.

Thus, in the embodiment of the present disclosure, the user at the client device 130 can determine which shooting device video is to be presented by inputting an instruction, so that switching of videos presented on the client device 130 is realized, the autonomy of the user is improved, and the requirements of the customer can be met better. In this way, the video presented on the client device 130 need not be identical to the video on the anchor electronic device and is no longer a passive video recipient, but rather, the video of interest can be selected autonomously by the user without affecting the anchor electronic device and other client devices 130.

In addition, the video presented on the center device 110 is not limited by the embodiment of the present disclosure, and may be, for example, a video shot by the center shooting device.

Alternatively or additionally, the client device 130 may receive 350 a look-around viewing operation by the user. Further, the client device 130 may present 360 a sequence of panoptic images.

In some embodiments, the user may click on a particular area on the interface of the client device 130 to perform a look-around viewing operation, such as clicking on a "look-around" button on the particular area. In some embodiments, the user may manipulate a particular gesture on the interface of the client device 130 to perform a look-around viewing operation, for example, the particular gesture is a circled or semi-arc.

Fig. 6 illustrates a schematic flow diagram of a process 600 of presenting a sequence of surround view images, in accordance with some embodiments of the present disclosure.

At block 610, the client device 130 determines a current frame of the composite video that corresponds to a current frame of the video to be presented in response to the look-around viewing operation.

Specifically, assuming that the current frame of the video to be presented is the tth frame, the tth frame of the composite video may be acquired, and it is understood that the tth frame of the composite video includes images captured by each of the capturing devices in the distributed capturing system.

At block 620, the client device 130 splits the current frame of the composite video into a plurality of images.

Specifically, the splitting may be performed based on the number of the plurality of photographing devices, that is, the number of the plurality of images is equal to the number of the plurality of photographing devices. In some embodiments, the plurality of images are images respectively captured by a plurality of capturing devices.

At block 630, the client device 130 obtains a sequence of panoramic images based on the plurality of images.

In some embodiments, the plurality of images may be ordered according to the position of the capture device to obtain a sequence of all-round images. That is, a plurality of images may be sequentially arranged in order of positions of a plurality of photographing apparatuses to obtain a panoramic image sequence. For example, as shown in fig. 2, the image captured by the capturing device 122-i is located at the ith position of the all-round image sequence, and i is any value from 1 to 7.

In some embodiments, the plurality of images may be sequentially arranged in the positional order of the plurality of photographing devices with at least one frame interposed between each two adjacent images to form a panoramic image sequence. It is understood that, in this embodiment, the number of images in the image sequence is viewed around by the number of the plurality of photographing apparatuses.

Specifically, at least one frame may be inserted between two adjacent images by the frame insertion operation. The inserted at least one frame may be referred to as a virtual frame or an intermediate frame, and embodiments of the present disclosure do not limit the manner in which the frame is inserted. The interpolated frame may also be called a complement frame or an animation complement frame, and a virtual frame may be obtained by an algorithm such as local interpolation. In this way, by the frame interpolation processing, a virtual frame is interpolated between two adjacent images, and continuity of image change between the two adjacent images can be ensured.

For example, assume that the current frame is the t-th frame, the number of the plurality of photographing devices is m, and the plurality of images are images respectively photographed by the plurality of photographing devices, denoted as f1t, f2t, f3t, \8230;, fmt. As shown in fig. 7, 4 virtual frames may be inserted between each two images, resulting in a panoramic image sequence 700. Thus, the sequence of surround-view images obtained after frame interpolation includes the number of images: m +4 × (m-1).

In this way, the number of images in the sequence of surround view images can be expanded, making it more fluent when the sequence of surround view images is presented later.

It should be noted that the number of virtual frames inserted in the frame insertion process is not limited in the embodiment of the present disclosure. In some embodiments, the number of dummy frames inserted between each two adjacent frames may be a predetermined value, for example, the predetermined value is 4 in fig. 7, it is understood that the predetermined value may be other values. The preset value may be preset according to an angle between two adjacent photographing apparatuses, the number of photographing apparatuses, and the like. In some embodiments, the number of virtual frames inserted between two different adjacent frames may be equal or unequal, for example, the virtual frames inserted between f1t and f2t have a first number, while the virtual frames inserted between f2t and f3t have a second number, and the first number may be equal to or not equal to the second number.

At block 640, the client device 130 sequentially presents each image in the sequence of images in a round-robin order.

In some embodiments, the client device 130 may also present the corresponding image in the sequence of all-around images based on a side-to-side sliding operation by the user. In this way, the user can view the look-around effect of the target object 202 according to the needs of the user.

Therefore, the embodiment of the disclosure provides a real-time look-around live broadcast scheme based on a distributed shooting system, and the client device can receive the composite video from the central device, and then the client device can present the video to be presented or the look-around effect according to actual needs or user instructions and the like. In this way, a user at a client device can autonomously determine the content being presented, the client device no longer being a single passive recipient of the content, which can greatly enhance the user's interaction experience.

Fig. 8 shows a schematic flow diagram of a video presentation process 800 according to some embodiments of the present disclosure. Process 800 may be performed by client device 130 as shown in fig. 1.

At block 810, the client device 130 receives a composite video from the central device, the ith frame of the composite video being obtained based on the ith frame of the video captured by each of the plurality of capture devices at the same time in the distributed capture system, i being any positive integer. At block 820, the client device 130 determines a video to present based on the composite video, the video to present being associated with at least one of the plurality of capture devices. At block 830, the client device 130 renders the video to be rendered.

In some embodiments, the ith frame of the composite video is obtained by stitching ith frames respectively captured by a plurality of capturing devices at the same time. For example, at the same time, the multiple shooting devices respectively shoot the multiple corresponding frames, and then the central device may splice the multiple corresponding frames, and use the spliced frames as the frames corresponding to the time in the composite video.

In some embodiments, determining, by client device 130, a video to present based on the composite video may include determining each frame of the video to present by: the client device 130 determines an ith frame of the video photographed by a target photographing device, which is a photographing device located at a target position among the plurality of photographing devices, from the ith frame of the composite video; and determining the ith frame of the video to be presented according to the ith frame of the video shot by the target shooting equipment. Alternatively, the target position may be an intermediate position of the plurality of photographing apparatuses.

In some embodiments, determining, by client device 130, the video to present based on the composite video comprises: the client device 130 receives a user input instruction, the user input instruction indicating a target shooting device; and determining each frame of the video to be presented by: determining an ith frame of a video photographed by a target photographing apparatus from the ith frame of the composite video; and determining the ith frame of the video to be presented according to the ith frame of the video shot by the target shooting equipment. Thus, by sequentially taking the value of i as 1, 2 and 8230, each frame of the video to be presented can be obtained frame by frame. Alternatively, the input instruction of the user may be based on a slide operation of the user on the interface, which may be a left slide or a right slide to indicate that the target photographing apparatus is determined by a left shift or a right shift in position, respectively.

For example, for any frame in the composite video, such as the ith frame, the ith frame of the video captured by the target capturing device may be determined from the ith frame of the composite video as the ith frame of the video to be presented. Generally, the image size of the ith frame of the video to be presented is smaller than the image size of the ith frame of the composite video.

Alternatively or additionally, as shown in fig. 8, at block 840, the client device 130 receives a user look-around viewing operation for a current frame of the video to be rendered. At block 850, the client device 130 presents a sequence of look-around images corresponding to the current frame of the video to be presented in response to the look-around viewing operation.

In some embodiments, presenting the sequence of look-around images by the client device 130 in response to the look-around viewing operation may include: the client device 130 determines a frame from the composite video corresponding to a current frame of the video to be presented in response to the look-around viewing operation; splitting a frame corresponding to a current frame of a video to be presented in the determined composite video into a plurality of images respectively corresponding to a plurality of shooting devices; obtaining a sequence of look-around images based on a plurality of images; and presenting the sequence of surround view images. Illustratively, the number of the plurality of images is equal to the number of the plurality of photographing devices.

In some embodiments, obtaining the sequence of around images by the client device 130 based on the plurality of images may include: the client device 130 arranges the plurality of images in order of positions of the plurality of photographing devices to obtain a panoramic image sequence.

In some embodiments, the client device 130 obtaining the sequence of around images based on the plurality of images comprises: the client device 130 arranges the plurality of images in the order of the positions of the plurality of photographing devices; an intermediate frame is inserted between every two adjacent images of the plurality of images through an interpolation operation to obtain a sequence of the all-around images.

Fig. 9 shows a schematic flow diagram of a video presentation process 900 according to some embodiments of the present disclosure. Process 900 may be performed by central device 110 as shown in fig. 1.

At block 910, the hub device 110 receives a video captured by each of a plurality of capture devices in a distributed capture system. At block 920, the center apparatus 110 obtains a composite video based on videos captured by the plurality of capturing apparatuses, respectively, an i-th frame of the composite video being obtained based on the i-th frame of the videos captured by the plurality of capturing apparatuses, respectively, at the same time, i being any positive integer. At block 930, the hub device 110 sends the composite video to the client device.

In some embodiments, the central device 110 obtaining the composite video may include determining each frame of the composite video by: the center apparatus 110 stitches the i-th frame of the video individually photographed by the plurality of photographing apparatuses at the same time to obtain the i-th frame of the composite video. For example, at the same time, the multiple shooting devices respectively shoot the multiple corresponding frames, and then the central device 110 may splice the multiple corresponding frames, and use the spliced frames as the frames corresponding to the time in the composite video.

In some embodiments, it may further include: videos captured by a particular capture device in the distributed capture system are presented at the central device 110. For example, after acquiring videos captured by a plurality of capturing devices in the distributed capturing system, the center device 110 presents the videos captured by the target capturing device. For example, the target photographing device may be a device that interacts with a user in a distributed photographing system, or the target photographing device may be a device located at an intermediate position in the distributed photographing system.
