Abstract

The invention discloses a method and system for erasing and resetting time stamps in the process of generating a panoramic image, wherein the method includes the following steps: determining the entire time stamp area in the seconds conversion frame; moving the camera to the first preset point, Capture the first image, then move the camera to the second preset point, capture the second image, so that the area covered by the time stamp in the second image is exposed; find the part covered by the time stamp in the first image For the corresponding area of ​​the area in the second image, the image of the corresponding area is intercepted and backfilled into the first image to eliminate the time stamp; the videos captured by multiple cameras are eliminated according to the above steps, and then spliced ​​into Panoramic video; re-transplant the original location and identified time stamps to the new position of the panoramic video. The invention can fundamentally solve the problem of erasing the time stamp in the video, eliminates the time stamp in the real sense, and has better real-time performance and accuracy.

Description

technical field [0001] The invention relates to a method for erasing a time stamp, in particular to a method and system for erasing and resetting a time stamp in the process of generating a panoramic image. Background technique [0002] Each surveillance video usually has a timestamp. When multiple surveillance videos are fused into a panoramic video, multiple timestamps will appear at the same time. How to efficiently remove the timestamps that appear in the video is the main content of this algorithm research. [0003] There are two types of time stamp storage in existing surveillance video, one is video with electronic time track, the time stamp of this video is completely independent from the video file, and this time stamp can be artificially changes, which pose a security risk. The other is that the video and the time stamp are integrated, and the time stamp is an integral part of the video, so it cannot be changed, so the security performance is good. This method is...
