Embodiment 1

[0029] see figure 1 , the present invention provides a kind of multi-channel video synchronous method based on video content, comprises the following steps:

[0030] Step S01: Start multiple video recording devices

[0031] Turn on multiple video recording devices for shooting. Multiple video recording devices can be started synchronously through the same operating part, or each video recording device can be operated separately to start, no matter which method of starting does not affect the synchronization of multiple channels of video.

[0032] Step S02: Add a synchronization event and get multiple video signals

[0033] When multiple video recording devices are in the shooting process, add a synchronous event, so that each video recording device records the synchronous event to obtain multiple video signals, and the video of each video signal The synchronization events are included in the content.

[0034] Step S03: Obtain the time stamp information of the synchronous e...

Embodiment 2

[0040] like figure 2 and 3 As shown, the present invention provides a multi-channel video synchronization device based on video content, which can be used to synchronize multiple channels of video, thereby realizing the above steps S01 to S04. The multi-channel video synchronization device includes a base 1, four cameras 2 with wide-angle lenses placed on the base 1, a starting part 3 for simultaneously starting four cameras 2, four synchronous flashlights 4 and a button 5 for simultaneously starting four synchronous flashlights . The base 1 is supported by a bracket 12 . The cameras 2 and the synchronous flashlights 4 are set in one-to-one correspondence, and each synchronous flashlight 5 is set within the shooting angle range of a corresponding camera 2 . Each of the four cameras 2 has a wide-angle lens with a shooting angle greater than or equal to 90°, and each synchronous flash 4 is arranged one-to-one under the front side of the lens of one camera 2 . Four cameras 2...

Abstract

The invention provides a video-content-based multi-channel video synchronization method and device. The video-content-based multi-channel video synchronization method comprises the following steps: (1) starting up a plurality of video recording devices for shooting; (2) when the video recording devices are all in the shooting process, adding a synchronization event, and enabling all the video recording devices to record the synchronization even so as to obtain multiple video signals, wherein the video content of each video signal comprises the synchronization event; (3) after shooting, analyzing and extracting the synchronization event recorded in the video content of each video signal to obtain timestamp information of the synchronization event in each video signal; (4) synchronizing the multiple video signals according to the timestamp information of the synchronization event in each video signal. Compared with the prior art, the video-content-based multi-channel video synchronization method is simple and convenient to operate and lower in cost. The invention further provides a device including a plurality of video recording equipment and a plurality of synchronous flashlights, and the device is smart in structural design and suitable for shooting and synchronization of multi-channel video.

Description

technical field [0001] The invention relates to a multi-channel video synchronization method and device, in particular to a video content-based multi-channel video synchronization method and device. Background technique [0002] At present, panoramic video production is generally formed by splicing multiple videos. However, since the multi-channel videos are captured by multiple video recording devices, multiple video recording devices cannot achieve strict synchronization after pressing the button to start shooting at the same time and enter the shooting process, resulting in a gap between the multiple video signals A certain time difference, usually a time difference of a few frames. This time difference will lead to synchronization errors of multiple channels of video, resulting in image blurring, motion ghosting and other defects in the subsequent video stitching, and ultimately it is impossible to obtain a very clear panoramic video. [0003] In the prior art, in orde...
