Problems solved by technology

[0004] However, since the user spends a long time outside, the data volume of the recording is also very large, and it will take a long time to watch the recorded video from beginning to end.
It is not efficient to watch the recorded video by jumping, and it is possible to miss important picture changes

Embodiment Construction

[0019] A monitoring system often needs to record for a long time, and the recorded video is stored in a storage medium, such as a hard disk. When the user of the monitoring system finds that there is an abnormal situation in the monitored environment, the user needs to refer to the video tape to find the time point when the abnormal situation occurred.

[0020] For example, a surveillance system is filming a user's car. The user goes out, and after about one year, the user comes back and finds that the car has disappeared. At this time, the user must consult the recorded video data to know when the car disappeared. But because the time that the user goes out is quite long, so the data volume of video recording is also very huge, and watching video recording from beginning to end can consume quite a long time, therefore, the present invention has proposed an exquisite solution.

Abstract

The method includes steps: first, playing back multiple first parting cut images on one screen at same time; and each first parting cut image displays monitored image for same scene at different times from recorded video; next, selecting a first parting cut image with most difference to adjacent parting cut images; then, dividing the selected first parting cut image into multiple second parting cut images displayed on screen at same time; each second parting cut image displays monitored image for same scene at different times from recorded video. Repeating the said procedure to device image till to find out the time, when the difference between images is maximal.

Description

technical field [0001] The invention relates to a method for searching a picture of a monitoring system, in particular to a method for searching a picture of a monitoring system by using a split picture. Background technique [0002] Due to the increasingly frequent human social activities, the safety requirements for the working environment and the home environment are getting higher and higher in daily life. Especially in cities, in order to prevent sudden crimes or accidents, setting up surveillance systems is a common method. The monitoring system can automatically record the state of the environment. When a crime occurs, it can be used as a tool for proof; in normal times, it can also effectively deter crime. [0003] In order to completely record the surveillance images at all times, the video recording time of the surveillance system is generally quite long. When the user goes out for a long time, the surveillance system may need to record surveillance images for se...
