Abstract
The invention discloses a frame extraction storing method for digital video surveillance. The frame extraction storing method comprises the following steps of: setting safety time, carrying out frame extraction processing on video data stored in the safety time, storing the video data subjected to frame extraction, and carrying out frame extraction processing again. According to the frame extraction storing method for digital video surveillance, the safety time is set for digital video surveillance data, the frame extraction processing is carried out on the video data stored in the set safety time, and the video data subjected to the frame extraction is stored, so that the storage space is saved, the usage amount of a storage hard disk of the digital video surveillance is reduced, and then, the aim of saving cost is achieved.
Description
Technical field
The present invention relates to field of data storage, particularly, relate to a kind of digital video monitoring and take out the method that frame stores.
Background technology
At present, the video data that the user monitors by hard-disc recording in the existing digital video monitor system, but there is considerable defective in system, comprising: video record storage that (1) is single, can't compress processing to video record; (2) the necessary non-interrupted picture recording of video camera, network video server storage information constantly increases, and needs a large amount of hardware memory space, causes hardware cost and manual maintenance with high costs.(4) can only record a video and return monitor video and look into, do not have intelligence analysis and take out the frame memory function.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of digital video monitoring and take out the method that frame stores, conserve storage is to realize saving the advantage of cost.
For achieving the above object, the technical solution used in the present invention is:
A kind of digital video monitoring is taken out the method that frame stores, and may further comprise the steps:
Safety time is set, namely in one day 24 hours, the time period that video monitoring is comparatively safe, be made as E hour,
The video data that stores safe hard disk in above-mentioned E hour into is taken out frame to be processed, namely behind the every N frame extraction M frame to the video data of this section in the time, deposit it in hard disk again, wherein M〉0, N〉0, M〉N, and the monitoring stored video data amount of every day is made as K, and the hard disk occupancy of taking out behind the frame is F, and the video data behind the above-mentioned extraction N frame is carried out the sequential encoding mark, and the video data that will extract behind the N frame deposits in the hard disk according to coded markings is ascending, then F=(1-EM/24N) K;
The above-mentioned video data of taking out after frame is processed is taken out frame again process, namely set the existing video file of above-mentioned storage and once took out frame at one month, the storage video recording size of establishing month is H;
The video of storage in the hard disk one month is taken out frame process, wherein every Y frame extracts X frame, wherein X〉0, Y〉0, Y〉X, in hard disk, the space occupancy volume of taking out behind the frame is T, then T=(1-X/Y) H with the Video Data Storage behind the above-mentioned extraction X frame.
Technical scheme of the present invention, set safety time by the data to digital video monitoring, and the video data of storing in the safety time of setting is taken out frame process, the video data of taking out behind the frame is stored, thereby saved memory space, reduce the use amount of the storage hard disk in the data video monitoring, thereby reached the purpose of saving cost.
Embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, is not intended to limit the present invention.
A kind of digital video monitoring is taken out the method that frame stores, and may further comprise the steps:
Safety time is set, namely in one day 24 hours, the time period that video monitoring is comparatively safe, be made as E hour,
The video data that stores safe hard disk in above-mentioned E hour into is taken out frame to be processed, namely behind the every N frame extraction M frame to the video data of this section in the time, deposit it in hard disk again, wherein M〉0, N〉0, M〉N, and the monitoring stored video data amount of every day is made as K, and the hard disk occupancy of taking out behind the frame is F, and the video data behind the above-mentioned extraction N frame is carried out the sequential encoding mark, and the video data that will extract behind the N frame deposits in the hard disk according to coded markings is ascending, then F=(1-EM/24N) K;
The above-mentioned video data of taking out after frame is processed is taken out frame again process, namely set the existing video file of above-mentioned storage and once took out frame at one month, the storage video recording size of establishing month is H;
The video of storage in the hard disk one month is taken out frame process, wherein every Y frame extracts X frame, wherein X〉0, Y〉0, Y〉X, in hard disk, the space occupancy volume of taking out behind the frame is T, then T=(1-X/Y) H with the Video Data Storage behind the above-mentioned extraction X frame.
Safety time is accepted as unavoidable safety time for the user, and user oneself thinks video monitoring in the time, the time that monitoring ground can be comparatively safe.For example: under the home environment, basically all work out daytime, and household safe is relatively important, and substantially be in evening, and degree of safety is relatively high.So the comparatively safe time of this moment is: at 9 in evening is to point in mornings 9.The enterprise customer is then just opposite, to safety time is first: 9 of mornings are to point in evenings 9.
The frequency that setting is taken out frame in order to store video namely when store video, is taken out frame to the video that the user identifies oneself in the safety time, after extracting the M frame out in every N frame, then stores.
Take out the space of the shared hard disk of frame video, because the user is thought that the comparatively safe time is E hour, it has been carried out taking out the frame storage, so one day employed hard drive space of user is k, the hard drive space occupancy volume of taking out behind the frame is F=(1-EM/24N) K.
Intelligent storage carries out the frame of taking out regularly to the video file in the hard disk of having stored and stores, behind the every X frame extraction Y frame in the video file in the DISK to Image, is storing, to reduce hard disk working pressure and space.
If, present high-definition video monitoring equipment, per second can be taken the video of 15 frames, in safety time, behind extraction 5 frames wherein, is storing, and can save 1/3 of the interior memory space of former safety time; If frame is taken out in storage video recording per month to high-definition camera equipment, per second is taken out 5 frames, can be the user and reduces by 1/3 hard disk use amount, also can not allow the integrity degree loss of video too large simultaneously, has taken into account fail safe.
It should be noted that at last: the above only is the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment the present invention is had been described in detail, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
