In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.
In the description of the present invention, reference to the description of the terms "one embodiment," "some embodiments," "an illustrative embodiment," "an example," "a specific example," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
In the network video recorder, in order to ensure the minimum influence on the system performance when the video is stored as far as possible, the common video storage is stored in a multi-channel sequential mode, the video is directly covered in sequence when the video is covered, and the condition that the type of the video to be covered is not considered, so that the storage time of the alarm video is consistent with that of the common video, and the alarm video cannot be delayed. When the alarm record needs to be extracted and analyzed, the alarm record may be covered and cannot be extracted.
In the related art, the scheme adopted for solving the problems is to write videos of different video types into different partitions or hard disks when the network video recorder stores the videos, so that the storage time of the common videos and the alarm videos is inconsistent. However, there are two disadvantages, on one hand, for a single hard disk, different videos are stored in different areas, so that the magnetic head of the hard disk is not shifted during recording, thereby affecting the system performance. For example, when only one hard disk is available on the system, different areas can be set for storing different videos, similar to windows, the videos are divided into a C disk and a D disk, then a common video is written into the C disk, and an alarm video is written into the D disk. Two positions on a physical magnetic track of the hard disk may not be continuous, when data is written to a C disk, a magnetic head of the hard disk needs to be shifted to the position of the C disk, and when the data is written to a D disk, the magnetic head needs to be shifted to the position of the D disk, so that the magnetic head continuously shifts on a magnetic sheet, the service life of the hard disk is influenced, and the power consumption of a system is increased. On the other hand, if different videos are stored through different hard disks, a plurality of hard disks need to be started simultaneously when the system runs, and the power consumption of the system is increased; and simultaneously, the bandwidth of the system bus is influenced by writing in a plurality of hard disks.
Based on the above, embodiments of the present invention provide a method, an apparatus, a device, and a medium for prolonging storage time of an alarm video, which can prolong storage time of the alarm video without increasing storage capacity, facilitate extraction of the alarm video, and have a good utilization value in the fields of security, monitoring, and the like.
In a first aspect, as shown in fig. 1, the present invention provides a method for prolonging storage time of an alarm video, including:
step S110: acquiring a second video to be stored;
step S120: detecting an overlay mark of the stored first video;
step S130: if the covering mark of the first video is a second mark, covering and storing the second video to the storage position of the first video;
step S140: and if the covering mark of the first video is the first mark, modifying the covering mark of the first video into a second mark, continuously detecting the covering mark of the stored next video until the video with the covering mark as the second mark is detected, and covering and storing the second video to the storage position of the video.
In some embodiments, in the method for prolonging storage time of an alarm video, an override flag of a stored first video is detected by acquiring a second video to be stored, where the first video is stored before acquiring the second video. If the covering mark of the first video is a second mark, directly covering and storing the second video to the storage position of the first video; and if the covering mark of the first video is the first mark, modifying the covering mark of the first video into a second mark, continuously detecting the covering mark of the stored next video until the video with the covering mark as the second mark is detected, and covering and storing the second video to the storage position of the video. According to the embodiment of the invention, the covering mark of the stored video is detected by the method, the stored video is directly covered if the video is a common video, and the stored video is temporarily not covered if the video is an alarm video, so that the storage time of the alarm video can be prolonged under the condition of not increasing the storage capacity, the extraction of the alarm video is facilitated, and the method has good utilization value in the fields of security protection, monitoring and the like. In some embodiments, the above method is applicable to a situation where the storage space is full. If the storage space is sufficient, it is preferred to store the complete recordings as far as possible, again in order, regardless of the coverage.
In some embodiments, the first flag is FALSE, which is used to flag alarm recording for temporary non-coverage. The second mark is TRUE, is used for marking the ordinary video and can be directly covered.
In some embodiments, as shown in fig. 2, before the step S100 obtains the second video to be stored, the method further includes:
step S210: acquiring a first video;
step S220: judging whether the first video is an alarm video; if the first video is the alarm video, executing step S230; otherwise, go to step S240;
step S230: setting the video type of the first video as an alarm video, and setting the coverage mark as a first mark;
step S240: setting the video type of the first video as a common video, and setting the coverage mark as a second mark;
step S250: the first video is stored.
In some embodiments, the storing of the first video is: and acquiring a first video and judging whether the first video is an alarm video. If the first video is the alarm video, setting the video type of the first video as the alarm video, and setting the coverage mark as a first mark FALSE; otherwise, the video type of the first video is set as a common video, and the coverage flag is set as a second flag TRUE. Subsequently, the first video is stored.
In some embodiments, as shown in fig. 3, before detecting the overlay mark of the stored first video record in step S120, the method further includes:
step S310: judging whether the storage mode of the storage position of the first video is coverage storage or not; if the storage is the overlay storage, executing step S120; otherwise, go to step S320;
step S120: detecting an overlay mark of the stored first video;
step S320: the second video is directly stored.
In some embodiments, before detecting the overlay mark of the stored first video, it is further detected whether the storage mode of the storage location of the first video is overlay storage, i.e. whether overlay storage is allowed. If the storage is allowed to be covered, detecting the covering mark of the stored first video; if the covering storage is not allowed, the second video is directly stored without considering the difference between the alarm video and the common video, namely the second video is sequentially stored in sequence.
In some embodiments, the method for prolonging the storage time of the alarm video recording provided by the embodiment of the invention can be applied to a network video recorder. In practical application, as shown in fig. 4, the front-end network camera collects images to encode, identifies the images, triggers corresponding alarm, and sends the images and the alarm information to the network video recorder through the network. Specifically, the network camera can recognize human face features or a license plate and the like through an algorithm to trigger an alarm, and then sends the alarm to the network camera through a network protocol. The network video recorder receives the image and the alarm information sent by the network video camera through a UDP/TCP network protocol, combines and marks the image and the alarm information, stores the combined and marked image and alarm information as a data structure to a hard disk (the hard disk can be built in the network video recorder or can be an independent memory), and forms a first video. If the corresponding flag bit is judged, whether the video is an alarm video can be judged. It can be understood that the network video recorder may also obtain the first video in other manners, which is not limited in this embodiment of the present invention.
If the network video recorder judges that the first video is the alarm video, setting the video type of the first video as the alarm video, and setting the coverage mark as a first mark FALSE; otherwise, the video type of the first video is set as a common video, and the coverage flag is set as a second flag TRUE. Subsequently, the first video is stored.
The front-end network camera continuously collects images and sends the images to the network video recorder, and the network video recorder obtains a second video to be stored. And then detecting whether the storage mode of a hard disk for storing the first video is overlay storage, if so, detecting an overlay mark of the stored first video, and otherwise, directly storing the second video.
If the coverage mark of the first video is a second mark TRUE, which indicates that the first video is a common video and can be directly covered, the second video is stored in the storage position of the first video in a coverage manner; if the covering mark of the first video is a first mark FALSE, the first video is indicated as the alarm video, and the first video is not covered for the time of prolonging the storage time of the alarm video. Meanwhile, in order to avoid that the first video always occupies a storage space, only the first video is selected to be uncovered, and the first video is still covered next time, so that the covering mark of the first video needs to be modified into the second mark TRUE, and the first video can be covered after a new video is acquired next time. And after the coverage mark of the first video is changed into a second mark TRUE, continuously detecting the coverage mark of the stored video behind the first video until the common video with the coverage mark as the second mark TRUE is detected, and storing the second video in a storage position of the common video in a coverage manner. It will be appreciated that if no other video is following the first video, the second video is stored directly. By the method, the storage time of the stored alarm video can be prolonged, the alarm video can be extracted, and the method has good utilization value in the fields of security protection, monitoring and the like.
In some embodiments, as shown in fig. 5, if there are multiple network cameras, a switch is further required to be disposed between the network camera and the network video recorder, and the switch is configured to aggregate the code streams of the multiple network cameras to the network video recorder.
The method of the embodiment of the present invention is described below with a specific application example. It should be noted that the following percentages refer to the percentage of the storage space of the hard disk.
As shown in fig. 6, 75% of the normal videos are written into the hard disk for the first time, and the coverage flag is TRUE.
As shown in FIG. 7, since the hard disk is not yet full, 25% of the alarm recordings are written in sequence, and the override flag is FALSE. At this point the hard disk is full.
As shown in fig. 8, the hard disk receives 40% of the normal video, and the hard disk is full and needs to be overwritten to store the video. At this time, if the coverage flag TRUE of 75% of the normal videos in fig. 6 is detected, 40% of the normal videos are stored in the storage location of 75% of the normal videos in a coverage manner. At this point, 35% of the 75% of the normal recordings in fig. 6 remain.
As shown in fig. 9, the hard disk receives 45% of the alarm video to be stored, and now covers the remaining 35% of the normal video in fig. 6, and covers 10% of the 40% of the normal video written in fig. 8. Now that 10% has been written for the third round, the remaining 30% of the normal recording written in fig. 8.
As shown in fig. 10, the hard disk receives 40% of the normal videos again, and the remaining 30% of the 40% of the normal videos written in fig. 8 are all covered, and at the same time, 10% of the 25% of the alarm videos written in fig. 7 are covered. The 25% alarm recording written in fig. 7 now remains 15%.
Subsequent recordings will be written into the remaining 15% of the alarm recordings of fig. 7, and so on.
