Abstract

The invention discloses a real-time video image automatic de-duplication splicing method and system, and the method comprises the steps: deploying a plurality of cameras in a target scene, dividing the target scene into a plurality of key monitoring regions, and each camera corresponding to one key monitoring region; wherein marks are arranged at four corners of each key monitoring area, an overlapping area existing between two adjacent key monitoring areas, and two marks being shared by the two key monitoring areas in the overlapping area; collecting multi-channel videos of the plurality of cameras, and storing the multi-channel videos in a centralized manner; identifying a mark of each path of video, correcting each path of video according to a mark form and pixel coordinates, and extracting an image of a key monitoring region; and analyzing and de-duplicating the multiple paths of videos according to the marks in sequence, splicing and restoring the key monitoring regions of the multiple paths of videos into one path of video, and restoring the target scene. According to the automatic de-duplication splicing of the invention, ideal spliced images can be obtained for a pluralityof static cameras or a plurality of moving cameras.

Description

technical field [0001] The invention relates to the field of computer video image processing, in particular to a method and system for automatic deduplication and splicing of real-time video images. Background technique [0002] Video surveillance is widely used in all walks of life. In the same location or site, multiple cameras are generally installed and deployed. Many of the video images collected by multiple cameras overlap. They are used in monitoring, image recognition and scene restoration. In , it is necessary to deduplicate repeated images, and then restore the entire scene in splicing. [0003] Now in the post-processing of video images, there are often two ways to de-duplicate the video. One is to manually de-duplicate the image, and then restore it by splicing. This is time-consuming, and the real-time performance is not high. Some low-urgency and low-importance scenes are used, and only static images can be processed, and real-time video streams cannot be proc...
