Method and device for video storage

Abstract

The invention discloses a method and device for video storage. One specific execution mode of the method comprises the steps: obtaining two adjacent picture frames of a video from a first storage region for video buffering; comparing pixel points in preset regions of the two adjacent picture frames and judging whether there are changes of the pixel points or not; enabling the later picture frame to be stored in a second storage region if there are change of the pixel points; comparing pixel points in non-preset regions of the two adjacent picture frames and judging whether there are changes of the pixel points or not if there are no change of the pixel points; enabling the later picture frame to be stored in the second storage region and enabling the pixel points with change to be combined in a preset region if there are change of the pixel points. The execution mode can improve the efficiency of image processing.

Description

Technical field

[0001] This application relates to the field of computer technology, in particular to the field of video surveillance technology, and in particular to a method and device for video storage. Background technique

[0002] With the development of digital video processing technology and the improvement of people's awareness of safety protection, video surveillance technology has been more and more widely used, such as road condition video surveillance, home video surveillance, vehicle video surveillance and so on. In some surveillance videos, if there are no changes in multiple consecutive image frames of the video, these unchanged image frames not only occupy a limited storage space, but also bring unnecessary trouble to the retrieval and browsing of the video.

[0003] In the prior art, only valid image frames (changed image frames) are stored by filtering image frames of surveillance videos to save storage space and provide convenience for retrieval and browsing. Ho...
