The invention provides a method and device for splicing network video stream images, and the method comprises the steps: obtaining at least two paths of network video stream information, and buildingbuffering queues of frame data based on the network video stream information; wherein at least one frame of image is stored in each buffer queue; performing parallel decoding on the frame data in theat least two paths of network video stream information; obtaining a time stamp of the decoded frame image; according to the frame image timestamp and the timestamp weight coefficient, determining whether there is synchronization between each path of network video stream information; and if so, performing image splicing on the network video stream information corresponding to the synchronization. According to the invention, the acquired network video stream information is decoded and the acquired timestamp is compared with the timestamp weight coefficient; according to the method and the device, the network video streams are synchronized, whether the network video streams are synchronized or not is determined, and the images are spliced according to the synchronized network video stream information, so that the spliced images are complete, and the probability of dislocation and ghosting is reduced.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for splicing network video stream images. Background technique [0002] Multi-channel network video stream image stitching is a method to solve the problem that the angle of view of a single video stream is not enough to cover the panorama. It has a wide demand in some airports, squares, parks and other scenes that require a panoramic perspective. [0003] In actual scenarios, during the transmission of multiple network video streams, due to a variety of reasons, the decoded frame images of the video streams may not be consistent on the time axis. The formed image may produce misalignment or ghosting, and may even cause problems such as splicing failure. Contents of the invention [0004] In order to solve the problem in the prior art that the decoded frame images of the video stream are inconsistent in the position of the time axis, resulting in misalign...
