Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
In the conventional technology, the resolution of live video is usually 1080P or 4K, and good resolution cannot be provided for watching pictures in a large scene. The camera needs to shoot at a far position in order to observe the whole appearance of a large scene, so that the shot image can only see the approximate outline of an object, and if some local detail is required to be enlarged, information is lost, and the picture is blurred.
In the prior art, live broadcasting is divided into two modes, namely a single-lens single-view picture and a multi-lens multi-angle picture. A single lens can only see one specific angle, resulting in other angles not being visible. And the live broadcast picture is a plurality of split pictures with a plurality of lenses and a plurality of angles.
In order to conduct high-definition video live broadcast of a large scene, a billion-level pixel panoramic video live broadcast method is provided.
FIG. 1 is a flow diagram illustrating a billion-level pixel panoramic video live method in accordance with one embodiment. Referring to fig. 1, a giga-level pixel panoramic video live broadcasting method includes:
step S11, acquiring, by a plurality of camera arrays, a plurality of hundred million pixel image groups of different viewing angles, where the hundred million pixel image groups include a wide view field image and a narrow view field image.
And step S12, splicing the wide-field images in the multi-hundred million-level pixel image group into a panoramic video image.
Step S13, generating a virtual 3D model based on the panoramic video image.
Step S14, transmitting the virtual 3D model to a client.
And step S14, receiving a request of a client, wherein the request comprises an angle and an area selected by the client on the 3D model.
And step S15, sending the graphics or video stream corresponding to the request to the client.
In step S11, a plurality of images of giga-level pixels at different viewing angles are acquired by a camera array of a plurality of giga-level pixels.
Each camera array of hundred million level pixels comprises more than one wide view field camera, which can be a wide view field low resolution short focus camera, and is used for acquiring wide view field images; the system also comprises a plurality of narrow view field cameras which can be narrow view field high-resolution long-focus cameras and are used for acquiring high-definition narrow view field images. The images taken by the camera array of each hundred million pixels are thus a set of images comprising more than one wide field of view image and a plurality of narrow field of view images. The camera position and shooting angle in each camera array with hundred million-level pixels are calibrated, which area of the wide view field image corresponding to each local high-definition narrow view field image can be calculated according to calibration parameters and pixel values of the images, the coordinates of each image are calibrated, and the high-definition narrow view field images can be mapped to the wide view field image according to the calibrated coordinates.
Meanwhile, the shooting positions and the shooting angles of the camera arrays of the hundred million-level pixels are calibrated according to parameters tested in advance, so that images shot by the camera arrays of the hundred million-level pixels respectively have certain overlapping areas but are images with different visual angles, the overlapping areas are known, the shot images can be directly calculated through a preset algorithm and fixed parameters, the images are spliced, the overlapping areas are removed, smoothing is carried out, seams among the images are eliminated, and the cost of computing resources is greatly saved while the complete spliced images are obtained.
A camera array of many hundred million pixels can take images of scenes from a larger viewing angle, even 360 degrees panoramic images.
In step S12, the image group acquired by each camera array includes a wide view field image, and the wide view field images acquired by the plurality of camera arrays are stitched and cropped according to the pre-calibrated parameters, so as to obtain a panoramic video image.
In step S13, a virtual 3D model may be further generated from the panoramic video image.
In one embodiment, the billion-level pixel panoramic video live broadcasting method further comprises: the wide field of view image and the narrow field of view image are mapped onto the virtual 3D model. When the client rotates or scales the 3D model, the mapping image at the corresponding position can be obtained, the mapping image comprises a wide view field image and a narrow view field image, the mapped wide view field image or the mapped narrow view field image is selected according to the requested area and resolution, and the spliced and cut wide view field image or the mapped narrow view field image is provided for the client. The client can also zoom the image in the display device, and the server only needs to select the corresponding mapping image for cutting and splicing according to the area and resolution requested by the client.
And step S14, receiving a request of the client, wherein the request comprises the angle and the area selected by the client on the 3D model. After receiving the virtual 3D model, the client may rotate and scale the 3D model, and select an angle and a position in which the client is interested, for example, a target position and an area are selected on the model, and a request of the client is generated, and the request is sent to the server. For example, if the client selects a large area on the model, which indicates that the client wants to see a large-range image, the client only needs to cut and splice the corresponding wide-field image and provide the cut and spliced wide-field image to the client, and if the client selects a small-area, which indicates that the client wants to see local high-definition details, the client cuts and splices the corresponding narrow-field image and provides the cut and spliced narrow-field image to the client.
And step S15, sending the video stream corresponding to the request to the client. And taking the spliced images as frames, forming a video stream according to the time stamp, and sending the video stream to the client.
In one embodiment, the billion-level pixel panoramic video live broadcasting method further comprises: after a video stream is generated, detecting the similarity between continuous frames of the video stream in a Structural Similarity Index (SSIM) mode, and when the similarity is larger than a threshold value, determining the video stream as a reusable video stream;
the reusable video stream is stored in a database of the multi-level server. If the video stream is the reusable video stream, the reusable video stream is stored in a database of the multi-level server, and when other clients request the same video, the stored video stream can be sent to the clients, so that the response time delay of the request is reduced, and the resource overhead caused by repeated calculation is saved.
In one embodiment, after a request of a client is received, a database is inquired, and whether a reusable video stream corresponding to the request exists or not is judged;
sending the video stream corresponding to the request to the client comprises the steps of sending the reusable video stream to the client when the reusable video stream corresponding to the request exists, and splicing and cutting a plurality of wide view field images or a plurality of narrow view field images corresponding to the request when the reusable video stream corresponding to the request does not exist, so as to generate the video stream and send the video stream to the client.
The method is different from the traditional live broadcast method that the video stream is generated only once, all the clients watch the same video stream, but different video streams are generated according to the selection of different clients, pictures played by each client can be different, the generated reusable video streams can be stored in the server, the same request of different clients can be reused as far as possible, and the system time delay and the resource overhead are greatly reduced.
Through the above description, the billion-level pixel panoramic video live broadcast method provided by the text can realize online interactive live broadcast of billions or more pixel videos, support the rotation of the view angle of the picture to observe scenes at different angles, and also can zoom the picture being watched and maintain high-definition resolution. And realizing the semi-transmission of the video stream through the multiplexing of the video stream.
