Embodiment Construction

[0058] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0059] like figure 1 As shown, the timestamp elimination and reset method in the panoramic image generation process of the embodiment of the present invention comprises the following steps:

[0060] S1. Periodically determine the second position conversion frame according to the change of the second number, and determine the entire time stamp area in the conversion frame;

[0061] S2. Move 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...

Abstract

The invention discloses a timestamp eliminating and resetting method in the panoramic image generation process and a system thereof. The method comprises the following steps that an overall timestamp area in a second-place conversion frame is confirmed; a camera is moved to a first preset point to capture a first image and then moved to a second preset point to capture a second image so that the area of the second image covered by a timestamp is exposed; an area in the second image corresponding to the area in the first image covered by the timestamp is found, and the corresponding area image is intercepted and backfilled in the first image so that elimination of the timestamp is realized; timestamp elimination is performed on videos photographed by multiple cameras according to the aforementioned steps, and then a panoramic video is obtained via splicing; and the originally positioned and identified timestamps are transplanted to the new positions of the panoramic video again. A problem of elimination of the timestamps in the videos can be radically solved, which is timestamp elimination in true sense so that real-time performance and accuracy are great.

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...
