In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following further detailed description of the exemplary embodiments of the present application with reference to the accompanying drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not exhaustive of all embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
In an XR presentation environment for broadcast television programming, multiple stations are required to capture scene images. The multi-camera shooting refers to shooting the same scene from multiple angles and directions by using two or more cameras. By the aid of the non-coplanar large-screen projection display technology, scenes shot by multiple cameras are projected onto an LED large screen formed by a plurality of screen display units, so that naked-eye 3D pictures are displayed. Because the scene presented by the large LED screen corresponds to the angle shot by the camera, the director switches the lens at different angles during the program production process, and thus the stereoscopic effect on the large screen needs to follow the angle of the lens. In the prior art, when a machine position is switched, a display picture of an LED large screen has picture jitter of 1-2 frames, so that the picture is discontinuous, even flash or black frames occur, and the problem of flash or black frames is usually avoided by a manual means.
In order to solve the above problems, embodiments of the present application provide a large screen-based multi-camera virtual fusion method, which triggers multiple cameras to photograph in an alternating manner through a modulated external trigger signal, synchronously inputs frame signals output by the multiple cameras to a large screen controller through multiple channels corresponding to the multiple cameras, fuses the input frame signals of the multiple cameras through the large screen controller, and outputs the fused frame signals to a large screen for display. The method provided by the embodiment of the application is based on a high-frequency LED large-screen technology, according to different channels of large screens corresponding to different cameras, the camera is triggered to perform real shooting through the external trigger signal by modulating the external trigger signal of the real shooting of multiple camera positions, the accurate synchronization of the real shooting signal (frame signal) of the camera and the large screen display is realized, the display image jitter, the flash or the black frame of the large screen during the switching of the camera positions is avoided, and the stable shooting of the XR multiple camera positions is realized.
Fig. 1 is a flowchart of a large-screen-based multi-machine-position virtual fusion method according to an embodiment of the present application. As shown in fig. 1, the large-screen-based multi-machine-position virtual fusion method provided in this embodiment includes the following steps:
and S1, triggering the plurality of cameras to take pictures in an alternate mode through the modulated external trigger signal.
Specifically, a signal modulator modulates and generates a plurality of paths of pulse signals, the plurality of paths of pulse signals are respectively used as external trigger signals for real shooting of a plurality of cameras, and the plurality of cameras are triggered to shoot in an alternative mode. The frequency of the pulse signals generated by the modulation of the signal modulator is matched with the frame frequency of the camera, and the frequency of the superposition of the multi-path pulse signals is matched with the refresh rate of the large screen.
And S2, synchronously transmitting the frame signals output by the plurality of cameras to the large screen controller through a plurality of channels corresponding to the plurality of cameras.
And S3, fusing the input frame signals of the plurality of cameras through a large screen controller, and outputting the fused frame signals to a large screen for display.
In a specific embodiment, the camera is connected to the signal modulator via a first external control interface for inputting the pulse signal generated by said signal modulator. The large screen is connected with the large screen controller through a second external control interface so as to input the frame signal fused by the large screen controller.
Because the camera outputs shooting signals, the large screen corresponds to screen display signals, and the two signals are different signal sources. In the prior art, continuous signal switching cannot be realized during machine position switching, flash breaks exist in the middle, and the problem of flash breaks (such as jumping and broadcasting other pictures) is solved by a manual means. The problem of flash is solved by adopting a technical means, and a director switches the cameras according to a conventional operation mode in the program making process without manually operating to avoid the problem of flash.
In the actual shooting, the dual-camera is a basic unit of multiple cameras, and the signal modulation principle of the present application is described in detail below by taking the dual-camera as an example. As shown in fig. 2, CAM1 indicates camera No. 1, CAM2 indicates camera No. 2, LEDs indicate large screen controllers, High Level is an active signal, and Low Level is an inactive signal. The LED active signal is formed by superposing a CAM1 active signal and a CAM2 active signal, and the large-screen controller has two channels which are respectively matched with the CAM1 and the CAM 2. Assuming that the frame frequency of the camera is 60fps (frame per seconds), the refresh rate of the large screen of high frequency LEDs is 120 HZ. During the normal operation of the camera, a frame signal is output, the frame signal is a high-low level signal, the frequency of the frame signal is equal to the frame rate of the camera, namely the frequency of the frame signal is 60 HZ. And two paths of pulse signals are generated by the modulation of the signal modulator, and the phases of the high levels of the two paths of pulse signals are opposite to the phases of the low levels of the two paths of pulse signals. The two paths of pulse signals are respectively used as external trigger signals for real shooting by the CAM1 and the CAM2, and the CAM1 and the CAM2 are triggered to shoot by the cameras according to an alternate mode. Frame signals output by the CAM1 and the CAM2 are synchronously transmitted to the large-screen controller through corresponding channels, the large-screen controller fuses the frame signals of the two cameras, and the fused frame signals are output to a large screen through the same channel to be displayed. For three or more cameras (multiple cameras), the signal modulation principle is similar to that of the two cameras, and the frame frequency superposed by the multiple cameras needs to be ensured to be consistent with the refresh rate of the high-frequency LED large screen.
In the embodiment, the pulse frequency of the external trigger signal used for real shooting by the camera is ensured to be matched with the frequencies of the large screen and the camera through signal modulation, the large screen is linked with the camera through the external trigger signal, accurate synchronization of the large screen and the camera is realized, a director switches the camera position according to a conventional operation mode in the program production process, the problems of jitter, flash or black frames cannot occur, and the problems of flash, black frames and the like are avoided without manual operation.

Assuming that the frame frequency of the camera is 60fps (frame per seconds), the refresh rate of the large screen of high frequency LEDs is 120 HZ. During the normal operation of the camera, a frame signal is output, the frame signal is a high-low level signal, the frequency of the frame signal is equal to the frame rate of the camera, namely the frequency of the frame signal is 60 HZ. The signal modulator modulates and generates two paths of pulse signals, and the phases of high levels of the two paths of pulse signals are opposite to the phases of low levels of the two paths of pulse signals. The two paths of pulse signals generated by the signal modulator are respectively used as external trigger signals for real shooting by the CAM1 and the CAM2, and two cameras of the CAM1 and the CAM2 are triggered to take pictures in an alternating mode.
