Embodiment Construction
[0028] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0029] A method for realizing synchronous frames of panoramic video, comprising the following steps: S1, multiple devices start video recording;
[0030] S2. The plurality of devices receive the synchronization signal multiple times at the same time, and draw an identification code on the currently encoded video frame;
[0031] S3. Extract the synchronous frames with the identification codes respectively, and synchronously synthesize the panoramic video.
[0032] As an improvement of this technical solution, in the step S2, the currently coded video frame is a random frame.
[0033] As an improvement of the technical solution, the step S3 includes pairing the synchronization signals using the principle of proximity.
[0034] As an improvement of the technical solution, the identification code includes a ...

The invention discloses a method for implementing synchronous frames of a panoramic video. The method comprises the following steps of: S1, starting to record a video by a plurality of pieces of equipment; S2, simultaneously and repeatedly receiving a synchronous signal by the plurality of pieces of equipment, and drawing an identification code on a currently encoded video frame; and S3, respectively extracting the synchronous frames with the identification code, and synchronously synthesizing the panoramic video. A system for implementing the synchronous frames of the panoramic video is used for executing the method; the system comprises a microprocessor, an image acquisition module, a storage module and a display module; and the image acquisition module, the storage module and the display module are all connected with the microprocessor. One specially processed video frame is identified and used as a timestamp of the panoramic video, so that synchronization of the panoramic video is implemented. The defect that a conventional panoramic video cannot achieve an effect of providing a synchronous timestamp is overcome. By identifying the special video frame, a module does not need to be additionally added, the method and the system are more flexible and convenient to implement, and accurate synchronization can be implemented. The method and system can be widely applied to an image mosaic technology.
Description
technical field [0001] The invention relates to an image splicing technology, in particular to a method and a system for synchronizing frames of a panoramic video. Background technique [0002] I frame: Also known as internal picture, I frame is usually the first frame of each GOP (a video compression technology used by MPEG), which is moderately compressed and used as a reference point for random access, which can be used as an image. [0003] gop: Group of Pictures, the strategy affects the encoding quality: the so-called gop means a group of pictures, and a gop is a group of continuous pictures. [0004] YUV is a color coding method (belonging to PAL) adopted by the European television system, and is the color space adopted by PAL and SECAM analog color television systems. In modern color TV systems, three-tube color cameras or color CCD cameras are usually used to capture images, and then the obtained color image signals are separated, enlarged and corrected to obtain R...
