Description
Technical field
The invention belongs to field of video monitoring, and in particular to a kind of video monitoring method for quickly retrieving and system.
Background technique
Video monitoring has been widely applied to each corner of society now, and maximum two effects are first is that for real-time
The timely behavior that notes abnormalities of monitoring searches some image informations that user wants second, monitoring is had access in playback.It is supervised in playback
When the event image information oneself wanted is searched in control, a problem is often put in face of user, that is, does not know that event is sent out
The raw specific time, for example picture when article is lost is searched, so retrieval work becomes extremely passive and time-consuming, generally require
The screen a few hours even longer time is stared at, intently to prevent missing some details.How desired picture is quickly navigated to
Face is urgent problem.
This is the deficiencies in the prior art, therefore, in view of the above-mentioned drawbacks in the prior art, it is quick to provide a kind of video monitoring
Search method and system, are necessary.
Summary of the invention
It is an object of the present invention to for above-mentioned when the event image information oneself wanted is searched in playback monitoring, one
Problem is often put in face of user, that is, is not known the specific time that event occurs, for example is searched picture when article is lost
Face, so retrieval work becomes extremely passive and time-consuming, generally require intently to stare at screen a few hours it is even longer when
Between, to prevent missing some details defects, a kind of video monitoring method for quickly retrieving and system are provided, asked with solving above-mentioned technology
Topic.
To achieve the above object, the present invention provides following technical scheme:
A kind of video monitoring method for quickly retrieving, includes the following steps:
S1. reference pictures are set from monitor video；
S2. play back monitor video, and frame image each in monitor video and reference pictures compared, obtain abnormal time node and
Abnormal picture；
S3. output abnormality picture and the corresponding abnormal time node of abnormal picture.
Further, specific step is as follows by step S1:
S11. monitor video is obtained；
S12. a frame image is chosen from monitor video as concern picture；
S13. in concern picture delineation range as focus；
S14. concern image information and focus information are saved, as reference pictures.Video monitor personnel supervise in video
It controls in software through mouse drag, draws a circle to approve out using the picture point of oneself concern as the focus of concern picture, video playback
Software saves the picture position and pattern-information of the focus of delineation.
Further, specific step is as follows by step S2:
S21. video monitoring is played back；
S22. frame image each in monitor video and reference pictures are compared, obtains the frame image different from focus information, made
For abnormal picture；
It S23. is that sequence obtains the first frame exception picture occurred in monitor video with the time, as starting point exception picture, record
The timing node of starting point exception picture；
The last frame exception picture occurred in monitor video is obtained, as terminal exception picture, records terminal exception picture
Timing node；
From starting point exception picture to the frame image of terminal exception picture as abnormal frame；
S24. redirected link is set for starting point exception picture；
S25. preview screen is set for starting point exception picture.After getting reference pictures information, video playback software is to whole views
Frequency monitoring image frame carries out intelligent retrieval, analyzes the picture in pattern in same position, when picture occurs inconsistent, records
, there is the inconsistent video clip to before picture recovery to reference pictures next time from picture in the timing node of the abnormal picture of point
It is set as one section of abnormal frame, retains starting point exception picture for preview, and create the link for jumping to starting point exception picture.
Further, specific step is as follows by step S3:
S31. the redirected link of starting point exception image time node, terminal exception image time node, starting point exception picture is obtained
And preview screen, and generate list；
S32. video monitoring search result is exported with tabular form and is presented.By the abnormal frame retrieved and starting point exception picture pair
The timing node and preview screen answered, which provide to be presented in the form of a list, adjusts reader, for adjusting reader's preview or in detail confirmation.
The present invention gives following technical solution:
A kind of video monitoring quick retrieval system, including
