The embodiment of the disclosure provides a panoramic conference control method, which can be applied to an application environment as shown in fig. 1. Wherein the conference moderator 102 may be connected to at least one participant 104. The panoramic camera 106 may be connected with a cloud server 108. The conference host 102 and at least one participant 104 may also be respectively connected to the cloud server 108, for respectively acquiring panoramic video stream data acquired by the panoramic camera 106 in real time or acquiring panoramic video stream data pre-stored in the cloud server 108. Conference host 102 may obtain panoramic video stream data. When a user performs a panoramic video conference through the conference host 102, the conference host 102 displays a partial panoramic image of panoramic images generated using panoramic video stream data, and determines viewing angle information corresponding to the partial panoramic image currently displayed. In response to the view sharing instruction, the conference host 102 transmits view information to at least one participant 102, and the at least one participant 102 acquires panoramic video stream data and adjusts a portion of the panoramic image for display among panoramic images generated using the panoramic video stream data based on the received view information. Among these, conference host 102 and participant 104 may be, but are not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The portable wearable device may be a smart watch, smart bracelet, headset, or the like.
In one embodiment, as shown in fig. 2, a panoramic conference control method is provided, and the method is applied to the conference host 102 in fig. 1 for illustration, and includes the following steps:
S202, panoramic video stream data is acquired.
The panoramic video stream data refers to video data of capturing and displaying an omnidirectional view angle. The type of panoramic video stream data is also different according to different application scenes, for example, in an industrial production application scene, the type of panoramic video stream data can be a panoramic video of the current industrial production type. In an application scenario of device training, the type of panoramic video streaming data may be a panoramic video of a device type.
Specifically, a user may initiate a panoramic conference at a conference host. Conference moderators typically need to acquire panoramic video streaming data in a cloud server. In some application scenarios, in the event that the cloud server cannot connect to a panoramic camera on site. Panoramic video may be captured first with a panoramic camera. The panoramic camera then transmits the photographed panoramic video stream data to the cloud server (this case is applicable to roaming scenes). In other application scenes, under the condition that the cloud server can be connected with an on-site panoramic camera, the panoramic camera can send panoramic video to the cloud server in real time, and at the moment, the conference host can acquire panoramic video stream data in the cloud server in real time. In addition, it should be noted that, in some embodiments of the present disclosure, the conference may further include a voice function and/or a video function during the conference, and these functions are not described in detail because they already exist in the conventional conference technology at present.
In some exemplary embodiments, where the panoramic camera may be connected to the cloud server, the panoramic camera may push the panoramic video stream data to the cloud server through an RTMP (Real-TIME MESSAGING Protocol) network Protocol. RTMP (Real-TIME MESSAGING Protocol) is a Real-time messaging Protocol commonly used for Real-time data transmission over the internet, including audio, video and other multimedia data. Real-time performance of panoramic video stream data can be ensured through RTMP protocol. The conference host can acquire panoramic video stream data through webRTC streaming technology. WebRTC (Web Real-Time Communication) is a Real-time communication technology that can directly implement point-to-point audio, video and data transmission between Web browsers without the aid of third party plug-ins or software. The WebRTC technology is based on JavaScript APIs, and can realize real-time communication between browsers, including audio-video call, file sharing, and the like.
S204, displaying a first part of panoramic images in the panoramic images generated by utilizing the panoramic video stream data, and determining view angle information corresponding to the first part of panoramic images to be displayed currently. The partial panoramic image is determined based at least on a display window of the conference host.
The viewing angle information may include a horizontal viewing angle, a vertical viewing angle, and a viewing angle, among others. The horizontal viewing angle indicates a viewing angle rotation or shift of the observer in the horizontal direction. The vertical viewing angle indicates a viewing angle rotation or offset of the observer in the vertical direction. The field angle indicates the field of view of the observer, i.e. the width of the field of view of the picture that can be seen.
Specifically, after the conference host acquires the panoramic video stream data, the panoramic image may be generated by rendering based on the panoramic video stream data, and then the panoramic image is displayed on the conference host. Further, since the panoramic image is a 360 ° image, the entire panoramic image is not normally displayed on the conference host side, and only a part of the panoramic image is displayed. For example, a panoramic image of 0-90 degrees is displayed. Because the angles of the displayed images are different, the conference host can determine the view angle information corresponding to the currently displayed first part of panoramic image.
Still further, the displaying of the first portion of the panoramic image generated using the panoramic video stream data includes displaying the first portion of the panoramic image generated using the panoramic video stream data based on a display window of a conference host. It should be noted that, in the process of displaying the panoramic image, the conference host may adjust the displayed first part of the panoramic image according to the window of the panoramic image displayed by the conference host, for example, if the current window is relatively large, the viewing angle of the displayed first part of the panoramic image is relatively large. If the current window is smaller, the view angle of the currently displayed first partial panoramic image is smaller.
And S206, responding to a viewing angle sharing instruction, sending the viewing angle information to the at least one participant to instruct the at least one participant to acquire the panoramic video stream data, and displaying a second part of panoramic images in the panoramic images generated by using the panoramic video stream data based on the viewing angle information and a display window of the at least one participant.
Wherein the view sharing instruction may be an instruction to share the view of the conference host to at least one participant in some embodiments of the present disclosure. The second partial panoramic image has the same portion as the first partial panoramic image.
Specifically, the user may hit the view sharing virtual key at the conference host endpoint, and when detecting that the view sharing virtual key is hit, the conference host may determine to respond to the view sharing instruction. The conference moderator may send the currently determined view information to the at least one participant. After receiving the viewing angle information, at least one participant can simultaneously acquire panoramic video stream data from the cloud server. It should be noted that, the panoramic video stream data acquired by at least one participant is generally the same as the panoramic video stream data acquired by the conference host, so as to ensure the consistency of display and the synchronism of information when the panoramic video conference is performed. After the panoramic video stream data is acquired by at least one participant, a panoramic image may be generated and displayed using the panoramic video stream data in the manner of the conference host as mentioned above. In the displaying process, at least one participant can adjust the displayed second part of panoramic image according to the visual angle information to be consistent or similar to the first part of panoramic image displayed by the conference host side in order to ensure information synchronization. In addition, since the display window of at least one of the participant terminals has different sizes, the second partial panoramic image and the first partial panoramic image that are displayed are not necessarily identical, and therefore, after the at least one participant terminal determines the second partial panoramic image that needs to be displayed according to the viewing angle information, the second partial panoramic image that needs to be displayed may be further adjusted according to the display window. At this time, the view angle information of the partial panoramic image displayed by the at least one participant is the same as the view angle information of the panoramic image of the conference host, but the second partial panoramic image may be the same as the first partial panoramic image or may be different from the first partial panoramic image.
In some exemplary embodiments, for example, the current conference host displays a panoramic image with a window a, which can display a panoramic image in a range of 90 °. The center of the visual angle information displayed by the current conference host end is 180 degrees, and the first part of panoramic image is displayed according to the display range of the window, wherein the display range of the first part of panoramic image is 180 degrees to 45 degrees, and 180 degrees plus 45 degrees. The window for displaying the panoramic image at the current at least one conference end is B, and the range of the panoramic image which can be displayed is 100 degrees. After the viewing angle information is acquired, displaying a second partial panoramic image according to the display range of the display window, wherein the display range of the second partial panoramic image is 180-50 degrees, and 180 degrees+50 degrees. It is to be understood that the foregoing is only illustrative.
According to the panoramic conference control method, through panoramic video stream data, the visual angle information is sent to at least one participant, so that all the participants can acquire the same visual angle experience, interaction and discussion among participants are ensured to be based on consistent visual content, and conference efficiency and effect are improved. According to the display windows of different participant terminals and the current visual angle information, the displayed panoramic image part can be dynamically adjusted, and the diversified requirements can be better met. In addition, through enabling all the participant terminals to acquire the same visual angle experience, the time and space limitation can be broken, and people in different places can interact with the condition of the operation site in real time as if the people are in the same place, so that the quick information transmission, the instant problem solving and the collaborative promotion of work are realized. The system can achieve the effects of high efficiency, accuracy and consistency in cooperation under the support of remote cooperation no matter in complex engineering projects, emergency fault treatment or daily production operation, thereby greatly improving the working efficiency, reducing the cost and guaranteeing the operation quality. And sharing the visual angle to other meeting personnel, and synchronously focusing important field pictures. Through the function, each participant can pay attention to the same scene and picture, unnecessary communication cost is reduced, the accuracy of information transmission is greatly improved, and the fluency of on-site cooperation is ensured.
In one embodiment, as shown in fig. 3, the sending the view information to the at least one participant to instruct the at least one participant to obtain the panoramic video stream data, and displaying, based on the view information and a display window of the at least one participant, a second part of the panoramic image generated using the panoramic video stream data, includes:
S302, acquiring the visual angle information according to a preset first time period, and generating a visual angle information queue.
S304, sending the view angle information queue to the at least one participant according to a preset second time period to instruct the at least one participant to acquire panoramic video stream data, and acquiring the view angle information in the view angle information queue according to the first time period and time sequence, and displaying a second part of panoramic images in the panoramic images generated by using the panoramic video stream data based on the acquired view angle information in the view angle information queue and a display window of the at least one participant in sequence;
Wherein the first time period is less than or equal to the second time period.
In particular, in order to reduce frequent communication between the conference host and the at least one participant, and to ensure consistency of adjustment of the at least one participant according to the viewing angle information. The conference host can continuously collect the view angle information in a preset first time period, so that a view angle information queue is generated according to the collected time sequence, and the view angle information queue generally contains view angle information stored according to the time sequence. The conference host may send the generated viewing angle information queue to at least one participant according to a preset second time period. At least one participant can receive the visual angle information queue, acquire panoramic video stream data in the cloud server, and render the panoramic video stream data to generate a panoramic image. And then acquiring the view angle information in the video queue information according to the first time period and the time sequence, and displaying a second part of panoramic images in the panoramic images according to the acquired view angle information and the size of the display window of the participant in sequence.
In some exemplary embodiments, the conference host may begin to collect VIEW information at regular intervals (e.g., once for 30 ms), and generate a VIEW information queue and broadcast a cus_event_share_view EVENT to at least one participant at a fixed frequency, the EVENT carrying the VIEW information queue. At least one of the participants receives the viewing angle information queue, acquires the viewing angle information in the viewing angle information queue according to a fixed time and sequence (the fixed time is generally the same as the time of acquiring the viewing angle information, so as to ensure that the display effect is the same as the effect of switching the viewing angle), and displays the second partial panoramic image according to the acquired viewing angle information and the display window in the at least one of the participants. The CUS_EVENT_SHARE_VIEW EVENT is a custom EVENT used for sharing various information to at least one participant.
The data structure of the view information may be hlookat, vlookat, fov. "hlookat" is a parameter in a Panorama Viewer for controlling the rotation or horizontal deflection of the viewing angle in the horizontal direction. By adjusting the value of the "hlookat" parameter, the horizontal view angle in the panoramic image can be changed, thereby controlling the direction of the observed scene. This parameter is typically used in the context of Virtual Reality (VR) applications, panoramic pictures, or panoramic video players, etc., to change the direction of the viewer's line of sight, providing a more interactive and immersive experience. In panoramic viewers, vlookat parameters are typically used to control the vertical direction of the viewing angle (pitch angle). It defines the angle of inclination of the head, i.e. the angle of looking up or down, when the user is looking in a panoramic environment.
