Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to enable managers to catch the key points and achieve efficient monitoring management, the embodiment of the invention provides a monitoring video display method and device, electronic equipment and a computer readable storage medium.

First, a method for displaying a surveillance video according to an embodiment of the present invention is described below.

The method for displaying the surveillance video provided by the embodiment of the present invention can be applied to any electronic device that needs to display the surveillance video, such as a computer, a mobile phone, a processor, a server, and the like, and is not limited specifically herein. For convenience of description, the electronic device is hereinafter referred to simply as an electronic device.

As shown in fig. 1, a method for displaying a surveillance video, the method comprising:

s101, acquiring a monitoring video of each channel;

s102, determining a target channel to be highlighted based on the interest degree of an interest event included in the monitoring video of each channel;

s103, determining a corresponding target display window for highlighting of the target channel in a display screen according to a preset highlighting mode;

the display screen comprises a plurality of display windows, and each display window is used for displaying the monitoring video of one channel.

And S104, displaying the monitoring video of the target channel on the target display window.

Therefore, in the scheme provided by the embodiment of the invention, the electronic device can acquire the surveillance videos of each channel, determine the target channel to be highlighted based on the interest degree of the interesting event included in the surveillance video of each channel, and further determine the corresponding target display window for highlighting the target channel in the display screen in a preset highlighting manner, wherein the display screen includes a plurality of display windows, each display window is used for displaying the surveillance video of one channel, and the surveillance video of the target channel is displayed in the target display window. The electronic equipment can display the surveillance video of the target channel on the target display window based on the interestingness of the interesting event included in the surveillance video of each channel, so that the purpose of highlighting the surveillance video of the target channel to be highlighted is achieved, managers watching the surveillance video can quickly and sufficiently find the interesting event included in the surveillance video, and then timely process the interesting event, and efficient surveillance management can be achieved.

In step S101, the electronic device may obtain the monitoring video of each channel. The monitoring video of each channel may be a monitoring video shot by each monitoring device in real time, or may be a monitoring video stored locally by an electronic device, or a monitoring video stored by other electronic devices, which is reasonable and not specifically limited herein.

After the surveillance videos of the channels are acquired, in order to enable the manager to more conveniently and quickly determine the occurred event of interest, the electronic device may execute step S102, that is, determine the target channel to be highlighted based on the interest degree of the event of interest included in the surveillance video of each channel. The event of interest may be determined according to an actual monitoring scenario, for example, if the monitoring video is a monitoring video of a school, the event of interest may be a person gathering, a person loitering, a person falling, and the like.

The interest level of the event of interest is information capable of representing the interest level of the event of interest, and may be determined based on one or more of the occurrence frequency, type, area, and the like of the event of interest, which is not specifically limited herein. The electronic device may determine the target channel to be highlighted according to the interest degree of the event of interest included in the surveillance video of each channel. In one embodiment, the higher the interest level is, the more important the event of interest included in the surveillance video is, the channel corresponding to the surveillance video is the channel to be highlighted.

For example, if the surveillance video of a certain channel or some channels does not include an interesting event, the interest degree corresponding to the channel is very low, and the channel corresponding to the surveillance video is a target channel not to be highlighted; if the monitoring video of a certain or some channels includes more interesting events, the corresponding interestingness of the channel is higher, and the channel corresponding to the monitoring video can be the target channel to be highlighted.

Furthermore, the electronic device may determine a corresponding target display window for highlighting of the target channel in the display screen according to a preset highlighting manner, that is, perform step S103.

Since the surveillance videos of the respective channels are finally required to be displayed in a display screen for being viewed by a manager, the display screen may include a plurality of display windows, each display window being used for displaying the surveillance video of one channel. In order to highlight the surveillance video of the target channel to be highlighted, the electronic device may determine a target display window in the display screen for highlighting the surveillance video of the target channel according to a preset highlighting manner, for example, a display window with a fixed position may be used as the target display window, and for example, the display window may be an upper left corner display window, a middle display window, a lower right corner display window, and the like of the display screen, which is reasonable.

Furthermore, the electronic device may execute step S104, that is, the monitoring video of the target channel is displayed on the target display window, so that the manager may more easily determine the interesting event to be processed from the monitoring video, and the management efficiency is improved.

It should be noted that, no matter what the display mode is the preset highlighting mode, the monitoring videos shot by each monitoring device can be stored in the corresponding storage location for subsequent inquiry and playback of the monitoring videos.

As an implementation manner of the embodiment of the present invention, the display screen may include a plurality of display windows densely arranged in a non-rectangular polygon.

Although the surveillance video is required to be displayed to include the event of interest, the picture range of the event of interest, that is, the region of interest, only exists in a certain range in the video picture, and the edge portion does not belong to the region of interest, so in order to further improve the efficiency of displaying effective information by the surveillance video, the display screen may include a plurality of display windows that are non-rectangular polygons, and thus, the surveillance video picture displayed in the display window of the non-rectangular polygon does not include the region of non-interest of the edge.

The preset non-rectangular polygon may be a regular polygon or a non-regular polygon. Can be triangular, regular pentagon, regular hexagon, etc. The preset non-rectangular polygons corresponding to each channel may be the same or different, and are not specifically limited herein.

The display windows of the non-rectangular polygons are densely arranged, that is, gaps do not exist among the display windows, and the display windows are closely arranged, so that monitoring video pictures can be displayed in a display screen with a limited size as much as possible, and the display efficiency of the monitoring video is improved.

For example, in the display screen shown in fig. 2, a little yellow duck is an interesting event, and the farther the little yellow duck is away from the little yellow duck, the less the little yellow duck is in the interesting area, the greater the outward radiation distance from the little yellow duck, and the less the little yellow duck is in the interesting area. Therefore, the display picture can be cut according to the shape and size of the non-rectangular polygon display window to obtain a surveillance video picture with a proper size, namely a hexagonal area in the figure, and the non-rectangular polygon shown in fig. 2 is a hexagon.

After the surveillance video pictures corresponding to each display window are obtained, the electronic device can display the surveillance video pictures of each channel in the display windows which are densely arranged.

For example, as shown in fig. 3, there are 13 channels of surveillance videos, where the original video 410 is rectangular, and the display windows 420 are regular hexagons, and then the arrangement of the display windows in the display screen may be as shown in fig. 3. It can be seen that the original display screen capable of displaying the monitoring videos of 12 channels can display the monitoring videos of 13 channels in total from 1 to 13 after being arranged in a densely-paved mode of the polygonal display windows.

In one embodiment, since the general display screen is rectangular, and the display window after the closely-arranged display windows may not be rectangular, it is reasonable that the electronic device may display the monitoring videos of other channels in the vacant area, or fill the vacant area with a preset background, etc.

Under the condition of more channels, if the display screen cannot display the monitoring videos of all the channels on one screen, the electronic equipment can scroll to display the monitoring videos, and the scrolling direction, the scrolling speed, the time interval and the like can be set according to needs, and are not particularly limited. The electronic equipment can also provide a user operation interface, so that a user such as a manager can control the scrolling display of the monitoring video through the user operation interface so as to view the content required to be viewed by the user.

As can be seen, in the present embodiment, the display screen may include a plurality of display windows arranged in a non-rectangular polygonal arrangement. Therefore, the efficiency of displaying effective information by the monitoring video can be further improved, and the monitoring videos with more channels can be displayed on the basis of the original display screen. The display window shape may be configured and drawn by the user, and the shape may be selectable so that the surveillance video may be displayed according to the shape set by the user. Redundant pictures can be removed, and the privacy of users can be protected to a certain extent. Meanwhile, the display window layout required by the user can be formed in a densely paved mode, and the monitoring videos of the appointed channel can be selected for video frame cutting. The method can be applied to scenes such as curved screen display, household monitoring personalized display and the like, can ensure that a monitoring picture is not a monotonous squared figure any more, and has aesthetic effect.

As an implementation manner of the embodiment of the present invention, as shown in fig. 4, the step of determining the target channel to be highlighted based on the interest degree of the event of interest included in the surveillance video of each channel may include:

s401, determining whether the monitoring video of each channel comprises an interesting event and an abnormal event or not to obtain the interesting degree of the interesting event;

because the monitoring scenes have more collective activities, the content included in the monitoring videos of some channels is basically unchanged at a certain moment. For example, in the monitoring videos of the passages of the kindergarten, when the children collectively move about in the playground, there are few events to be monitored in the monitoring videos of other areas. Therefore, the electronic device can determine whether the surveillance video of each channel includes the event of interest and the abnormal event, and the determination result is the interest level of the event of interest.

Since the interest level of the event of interest determined at a certain time may not be accurate enough, in one embodiment, the electronic device may count whether the monitored video of each channel includes the event of interest and an abnormal event within a period of time, and determine whether the event of interest and the abnormal event occur within the period of time as the interest level of the event of interest, or determine whether the event of interest and the abnormal event occur within a unit of time and determine as the interest level of the event of interest.

S402, determining the activity of each channel according to the interest degree of the interest event;

next, the electronic device may determine the activity of each channel according to the interest level of the event of interest. The interest degree of the interesting event comprises the following steps: including events of interest and exceptions, including events of interest but not exceptions, not including events of interest but not exceptions, and not including events of interest and exceptions.

The electronic device may preset a correspondence between the activity level and the interest level of the event of interest, and further determine the activity level of each channel according to the correspondence, in an embodiment, the correspondence is as follows:

degree of liveness	Interestingness of an event of interest
		0	Excluding events of interest and exceptions
1	Not including events of interest but including exceptional events
		2	Including events of interest but not including exception events
3	Including events of interest and exceptions

And S403, determining the channel with the activity reaching the preset activity as a target channel to be highlighted.

After determining the activity of each channel, the electronic device may determine whether the activity of each channel reaches a preset activity, and if not, it indicates that the activity of the channel is low, and may not include the interesting event and the abnormal event, or includes fewer interesting events and abnormal events, and then the electronic device may determine that such a channel is determined as a target channel that is not to be highlighted.

If the preset activity level is reached, which indicates that the activity level of the channel is high, and may include more interesting events and abnormal events, the electronic device may determine that such channel is determined as the target channel to be highlighted.

Correspondingly, the step of displaying the surveillance video of the target channel in the target display window may include:

displaying the original monitoring video of the target channel on the target display window, and displaying the monitoring video of the sub-area of the monitoring video of the target channel on the non-target display window.

Because the activity of the non-target channel is low, no event needing to be processed occurs, the activity of the target channel is high, and the event needing to be processed is likely to occur, the electronic equipment can display the original monitoring video of the target channel on the target display window and display the monitoring video of the sub-area of the monitoring video of the target channel on the non-target display window.

For example, there are 4 channels D1-D4 of surveillance videos, as shown in fig. 5, the target display window is the display window 510 at the upper left corner of the display screen, and the electronic device determines that the activity of the channel D1 reaches the preset activity, and the activities of the channels D2-D4 do not reach the preset activity, so that the electronic device may display the original surveillance video on the channel D1 in the display window 510, and the non-target display windows corresponding to the channels D2-D4 display the surveillance videos of the sub-areas a-c of the surveillance video of the channel D1.

It can be seen that, in this embodiment, the electronic device may determine whether the surveillance video of each channel includes an interesting event and an abnormal event, obtain an interesting degree of the interesting event, determine an activity degree of each channel according to the interesting degree of the interesting event, further determine a channel with an activity degree reaching a preset activity degree as a target channel to be highlighted, further display an original surveillance video of the target channel in a target display window, and display a surveillance video of a sub-region of the surveillance video of the target channel in a non-target display window. Therefore, the finally displayed monitoring videos comprise the original videos of the channels with high liveness and the monitoring videos corresponding to all the sub-areas, managers can quickly and accurately determine the events needing to be processed, and the monitoring management efficiency is greatly improved.

As an implementation manner of the embodiment of the present invention, after the step of displaying the monitoring video of the sub-region of the monitoring video of the target channel in the non-target display window, the method may further include:

Because the interesting events and abnormal events occurring in the monitored area may change at any time, in order to enable the manager to view the occurring events, the electronic device may calculate the activity of each channel in real time, and when the activity of the non-target channel reaches the preset activity, it indicates that the monitoring video of the non-target channel includes more interesting events and abnormal events, so that the original monitoring video of the non-target channel can be displayed on the non-target display window corresponding to the non-target channel, so that the manager can view the occurring events in time and process the events in time.

It can be seen that, in this embodiment, when the activity of the non-target channel reaches the preset activity, the electronic device may display the original monitoring video of the non-target channel on the non-target display window corresponding to the non-target channel, so as to ensure that when an event occurs in the monitoring area of the non-target channel, the monitoring video of the non-target replacement channel can be displayed in time, so that a manager can check the occurred event in time and process the event in time.

As an implementation manner of the embodiment of the present invention, as shown in fig. 6, the step of determining the target channel to be highlighted based on the interest degree of the event of interest included in the surveillance video of each channel may include:

s601, counting the number of interesting events included in the monitoring video of each channel in the current time period, and calculating the occurrence frequency of the interesting events;

to facilitate determining the frequency of occurrence of the event of interest, the electronic device may preset a time period, which may be, for example, 1 minute, 5 minutes, 10 minutes, etc. In this way, the electronic device may count the number of interesting events included in the surveillance video of each channel in the current time period according to the preset period, and further calculate the occurrence frequency of the interesting events.

The occurrence frequency β of the events of interest is equal to the ratio of the number m of the events of interest to the preset time period duration t, i.e., β is m/t. For example, in the current time period, the electronic device counts the number m of the events of interest to be 5, and the preset time period duration t is 5 minutes, so that the frequency β of the events of interest is 5/5 ═ 1 time/minute.

S602, determining the interest degree of the interest event corresponding to each channel based on the interest degree and the occurrence frequency of each interest event corresponding to the current time period;

next, the electronic device may determine the interest level of the event of interest corresponding to each channel based on the interest level and the occurrence frequency of each event of interest corresponding to the current time period. Since the corresponding importance levels of the events of interest may be different at different times, the interest levels may also be different. The higher the importance level of the event of interest, the higher the interest level of the event of interest. The electronic device may first determine the interest level of each event of interest during the current time period.

For example, assume that the surveillance video of each channel is the surveillance video of a certain school, and the time corresponding to the current time period is the next class time period. Then the level of interest of each event of interest can be determined based on the outdoor activity that the student will perform during the course of the day. For example, the interest level of a playground face detection event is 10%, the interest level of a people group event is 70%, the interest level of a school gate face detection event is 100%, the interest level of a people loitering event is 80%, and the like.

The interest degree of the interesting event represents the importance degree of the interesting event, and the occurrence frequency represents the occurrence frequency of the interesting event, so that the greater the interest degree of the interesting event is, the greater the interest degree of the interesting event can be determined by the electronic equipment to be; the higher the frequency of occurrence of the event of interest, the greater the level of interest the electronic device can determine for the corresponding event of interest. For example, the electronic device may determine the interestingness of the event of interest as the sum of the interestingness and the frequency of occurrence.

S603, determining the channel of which the interest degree of the interest event is not lower than the preset interest degree as a target channel to be highlighted.

After the interest degree of the event of interest corresponding to each channel is determined, since the higher the interest degree of the event of interest is, the more and more important the event of interest occurs in the monitoring area corresponding to the channel, the electronic device may determine that the channel of the event of interest with the higher interest degree needs to be highlighted, and further may determine that the channel of the event of interest with the interest degree not lower than the preset interest degree is the target channel to be highlighted. The preset interest degree may be determined according to factors such as an average value of interest degrees of events of interest of each event of interest counted in advance, and the like, and is not specifically limited herein.

After the target display window is determined, in order to highlight the surveillance video of the target channel, the electronic device may determine that the target display window displays the original surveillance video of the target channel, and the non-target display window displays the surveillance video of a sub-region of the surveillance video of the target channel, or displays the surveillance video of the non-target channel according to a certain rule, which is reasonable.

When the next preset period comes, the electronic device can still determine the target channel to be highlighted according to the above method, and further, the electronic device can re-determine the target channel to be highlighted based on the interest degree of the event of interest of each channel in each preset period, so as to display the monitoring video in a more appropriate manner.

It can be seen that, in this embodiment, the electronic device may count the number of interesting events included in the surveillance video of each channel in the current time period, calculate the occurrence frequency of the interesting events, determine the interest level of the interesting event corresponding to each channel based on the interest level and the occurrence frequency of each interesting event corresponding to the current time period, determine a channel with the interest level of the interesting event not lower than the preset interest level as a target channel to be highlighted, further display the original surveillance video of the target channel in the target display window, and display the surveillance video of the non-target channel in the non-target display window according to the preset display rule. In this way, the surveillance video of the target channel with high interest level of the event of interest can be displayed at a more prominent position, so that the manager can more easily view and process the occurred event of interest.

As an implementation manner of the embodiment of the present invention, the step of displaying the monitoring video of the non-target channel in the non-target display window according to the preset display rule may include:

sequencing the non-target channels according to the interest degree of the interest events corresponding to the non-target channels; determining a non-target display window corresponding to each non-target channel according to the sequencing result, and displaying the original monitoring video of the non-target channel in the corresponding non-target display window; or displaying a preset image on the non-target display window.

If the interest degree of the event of interest is lower than the preset interest degree, it indicates that the importance degree of the event of interest included in the surveillance video corresponding to the channel is not high, or the event of interest does not occur, the electronic device may determine that the event of interest is a non-target channel.

In an embodiment, the electronic device may rank the non-target channels according to the interest degrees of the events of interest corresponding to the non-target channels, and then determine the non-target display window corresponding to each non-target channel according to the ranking result. For example, there are 4 channels D1-D4 of surveillance videos, the electronic device determines that the channel D1 is a target channel and the other channels are non-target channels, and the results obtained by sorting the non-target channels according to the interest degrees of the events of interest corresponding to the non-target channels from high to low are D2, D4, and D3, so that, taking the display screen shown in fig. 5 as an example, it may be determined that the non-target display windows corresponding to the channels D2, D4, and D3 are a display window at the upper right corner, a display window at the lower right corner, and a display window at the lower left corner, respectively.

Furthermore, the electronic device can display the original video of the non-target channel in the corresponding non-target display window.

In another embodiment, for a non-target channel, the electronic device may determine a preset image corresponding to the non-target channel, where the preset image may include prompt information such as no abnormality. For example, the monitoring area corresponding to the non-target channel is a classroom, and the preset image may include "classroom no exception" prompt information. The electronic equipment can display the preset image on the non-target display window, so that a manager can immediately know that no abnormal phenomenon occurs in a classroom at the current time.

As can be seen, in this embodiment, the electronic device may rank the non-target channels according to the interest degrees of the events of interest corresponding to the non-target channels, determine the non-target display window corresponding to each non-target channel according to the ranking result, and display the original monitoring video of the non-target channel in the corresponding non-target display window. Or displaying a preset image in the non-target display window. Therefore, the monitoring video of the target channel with important interesting events can be displayed on the target display window, the display windows of other channels can be displayed according to the sequencing result of the interesting degrees, or the preset image is displayed, so that managers can quickly distinguish the conditions of the monitoring areas corresponding to the channels, and the monitoring management efficiency is improved.

As an implementation manner of the embodiment of the present invention, after the step of displaying the preset image on the non-target display window, the method may further include:

Because the interesting events occurring in the monitored area may change at any time, in order to enable the manager to view the occurring events, the electronic device may calculate the interesting degree of the interesting event of each channel in real time, and when the interesting degree of the interesting event of the non-target channel reaches the preset interesting degree, the original monitoring video is displayed on the non-target display window corresponding to the non-target channel, so that the manager can view the occurring events in time and process the events in time.

Therefore, in this embodiment, when the interest level of the event of interest in the non-target channel reaches the preset interest level, the electronic device may display the original monitoring video on the display window corresponding to the non-target channel, so as to ensure that the monitoring video of the non-target channel can be displayed in time when the event occurs in the monitoring area of the non-target channel, so that the manager can check the event in time and process the event in time.

As an implementation manner of the embodiment of the present invention, the step of determining the interest level of the interest event corresponding to each channel based on the interest level and the occurrence frequency of each interest event corresponding to the current time period may include:

according to the formula gamma_iα a + β B and

the degree of interest gamma of the event of interest corresponding to each channel is determined.

For example, if the number of events of interest corresponding to the channel D2 is 3, the degree of interest corresponding to the event of interest a is 10%, the occurrence frequency is 5, the degree of interest corresponding to the event of interest B is 70%, the occurrence frequency is 2, the degree of interest corresponding to the event of interest c is 20%, the occurrence frequency is 4, the preset constant a is 10, and the preset constant B is 20, then the degree of interest γ of the event of interest of the channel D2 is (10% × 10+5 × 20) + (70% × 10+2 × 20) + (20% × 10+4 × 20) × 222.6.

For example, in order to determine the interest level of the interest event a corresponding to each channel, the interest levels of the interest event a at different dates and time periods may be preset, for example, as shown in the following table:

therefore, in this embodiment, the electronic device may calculate the interest level of the accurate event of interest for each channel according to the above formula.

As an implementation manner of the embodiment of the present invention, the step of determining the target channel to be highlighted based on the interest degree of the event of interest included in the monitoring video of each channel may include:

determining the type of the interesting event included in the monitoring video of each channel; and determining the channel with the highest interest degree as a target channel to be highlighted based on the corresponding relation between the preset type and the interest degree.

Because the importance degrees of different types of interesting events are different, in order to facilitate the processing of managers, the electronic device can determine the type of the interesting event included in the monitoring video of each channel, and further determine the channel with the highest interest degree as the target channel to be highlighted based on the corresponding relation between the preset type and the interest degree.

Because the interest degree of the type of interest event corresponding to the target channel is the highest, the type of monitoring video corresponding to the target channel can be displayed on the target display window by the monitoring video, so that the type of interest event can be highlighted. For other types of surveillance videos, the surveillance videos may be displayed in different types in the non-target display window, that is, the same type of surveillance video may be displayed in one non-target display window.

For example, the electronic device determines that the types of the events of interest included in the surveillance videos of the channels include a face event, a vehicle alarm and a person group, the degree of interest corresponding to the face event is highest, and the target display window is window 1, then the electronic device may determine that the surveillance video with the type of the event of interest as the face event is displayed in window 1, the surveillance video with the type of the event of interest as the vehicle alarm is displayed in window 2, and the surveillance video with the type of the event of interest as the person group is displayed in window 3.

As can be seen, in this embodiment, the electronic device may determine the type of the event of interest included in the surveillance video of each channel, determine, based on the preset correspondence between the type and the degree of interest, that the channel with the highest degree of interest is the target channel to be highlighted, display the surveillance video of the type corresponding to the target channel in the target display window, and display the surveillance video of other types in the non-target display window. Therefore, when watching the monitoring video, the manager can more easily find the event needing to be processed, and the monitoring management efficiency is improved.

It should be noted that, for any of the above monitoring video display modes, the display windows may be non-rectangular polygons and arranged in a densely-tiled manner to remove edge regions of the monitoring video picture, thereby further improving the monitoring video display efficiency and the monitoring management efficiency.
