The higher monitoring center often needs to call the working scene of the lower monitoring center and display the working scene on the spliced screen of the higher monitoring center.

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 solve the problems in the prior art, embodiments of the present invention provide a method and an apparatus for adjusting a scene layout, an electronic device, and a storage medium, so as to implement matching between a restored working scene and a size of a mosaic screen of a superior monitoring center.

First, an application scenario of the scene layout adjustment method provided in the embodiment of the present invention is introduced, and the scene layout adjustment method in the embodiment of the present invention may be applied to any video monitoring system having at least a 2-level monitoring center, for example: such as the video surveillance system with a level 3 surveillance center shown in fig. 1.

In some examples, the video surveillance system having at least a level 2 surveillance center may be ranked according to a company architecture, for example, the company's surveillance system is ranked into level 2 according to head office and branch offices, that is: the monitoring center corresponding to the head office and the monitoring center corresponding to the branch office.

In still other examples, the video surveillance system having at least 2 levels of surveillance centers may also be ranked by administrative area, for example, by department 1 of administrative area a and department 2 of administrative department 1, the video surveillance system is ranked by 2, that is: the monitoring center corresponding to the department 1 and the monitoring center corresponding to the department 2.

The scene layout adjusting method applied to the superior monitoring center and the scene layout adjusting method applied to the inferior monitoring center in the embodiments of the present invention can match the size of the working scene recovered by the superior monitoring center with the size of the spliced screen of the superior monitoring center when synchronizing the video of the inferior monitoring center to the superior monitoring center.

It should be understood that the upper monitoring center and the lower monitoring center are referred to herein as being opposite.

For example, when the higher level monitoring center also corresponds to a higher level monitoring center, the higher level monitoring center may serve as a lower level monitoring center and the higher level monitoring center may serve as a higher level monitoring center, respectively.

For another example, when the lower level monitoring center further corresponds to a lower level monitoring center, the lower level monitoring center may serve as a higher level monitoring center and the lower level monitoring center may serve as a lower level monitoring center, respectively.

Next, a scene layout adjustment method according to an embodiment of the present invention is described, as shown in fig. 2, which is a flowchart of a first implementation manner in which the scene layout adjustment method according to the embodiment of the present invention is applied to a superior monitoring center, and in fig. 2, the method may include:

s210, receiving first scene data sent by a lower monitoring center.

Wherein the first scene data may include: the method comprises the steps of obtaining data of service functions operated in a lower-level monitoring center, and first splicing screen information and first resolution information of a splicing screen of the lower-level monitoring center, wherein the first splicing screen information comprises the line number and the column number of the splicing screen of the lower-level monitoring center.

In some examples, the data of the business function operated at the lower monitoring center may include: data such as the name of the surveillance camera, image layout, recording time period, surveillance area, etc., in some examples, the scene data may further include: program data used in a working scenario in which the lower level monitoring center operates, for example: variable data, cache data, a base library and other bottom layer parameters.

In some examples, the lower monitoring center may actively send the first scene data to the upper monitoring center, and the lower monitoring center may also send the first scene data of the locally running working scene to the upper monitoring center after receiving the call request sent by the upper monitoring center. In this way, the upper monitoring center can receive the first scene data sent by the lower monitoring center.

In some examples, in order to reduce the influence on the working scene operated by the subordinate monitoring center, the subordinate monitoring center may perform snapshot processing on first scene data of the working scene operated locally, and then send the scene snapshot data obtained after the snapshot processing to the superior monitoring center.

In some examples, the subordinate monitoring center may perform snapshot processing on the first scene data to be transmitted by using a copy-on-write or I/O redirection technique.

After receiving the first scene data sent by the subordinate monitoring center, the superior monitoring center may obtain the first mosaic screen information and the first resolution information of the mosaic screen of the subordinate monitoring center from the first scene data.

In some examples, the monitoring video call request may request to call a monitoring video of one window in a working scene running in the lower monitoring center, or may request to call monitoring videos of multiple windows, and therefore, the first scene data may include scene data corresponding to at least one window.

S220, second spliced screen information and second resolution information of the local spliced screen are obtained.

And the second spliced screen information comprises the line number and the column number of the local spliced screen.

In some examples, when the scene layout adjustment method according to the embodiment of the present invention is applied to a superior monitoring center, the local mosaic screen may be a mosaic screen of the superior monitoring center.

In order to enable the recovered working scene to be matched with the size of the spliced screen of the superior monitoring center after the superior monitoring center receives the first scene data sent by the inferior monitoring center, in the embodiment of the invention, the superior monitoring center can acquire the second spliced screen information and the second resolution information of the spliced screen of the superior monitoring center.

In some examples, the second mosaic screen information and the second resolution information of the mosaic screen of the superior monitoring center may be stored in a control device of the superior monitoring center. The control equipment is used for controlling the display of the image by the spliced screen spliced by the plurality of display screens of the upper monitoring center.

And S230, calculating a first zooming parameter for zooming the working scene operated by the lower monitoring center according to the first spliced screen information, the first resolution information, the second spliced screen information and the second resolution information.

In some examples, the lower monitoring center may be one, and the scene data received by the upper monitoring center may be scene data sent by one lower monitoring center. After the previous monitoring center acquires the first spliced screen information, the first resolution information, the second spliced screen information and the second resolution information, a first zooming parameter for zooming a working scene operated by the next monitoring center can be calculated according to the first spliced screen information, the first resolution information, the second spliced screen information and the second resolution information.

Further, the upper monitoring center may calculate the line scaling parameter s by using the following formula₁And column scaling parameter s₂Then scaling the parameter s in the row₁And column scaling parameter s₂The larger parameter is selected as the first scaling parameter:

wherein x is₁For the mosaic screen row in the first mosaic screen informationNumber, y₁For the number of columns, a, of the first tiled screen information₁As the row pixel values in the first resolution information, b₁Is a column pixel value, x, in the first resolution information₂For the number of mosaic screen lines, y, in the second mosaic screen information₂For the number of columns, a, of the mosaic screen in the second mosaic screen information₂As line pixel values in the second resolution information, b₂The column pixel value in the second resolution information is the number of pixels in the vertical direction of each screen in the mosaic screen, and the column pixel value is the number of pixels in the horizontal direction of each screen in the mosaic screen, for example, a screen with a resolution of 720p, a row pixel value of 720, and a column pixel value of 1280.

For example, as shown in fig. 3a, if the mosaic screen 310 of the lower monitoring center is formed by splicing 4 display screens, the first mosaic screen information acquired by the upper monitoring center is 2 rows and 2 columns, and if the resolution of each display screen is 720p, the first resolution information 720p of the mosaic screen of the lower monitoring center, and if the mosaic screen of the upper monitoring center is the mosaic screen 320 shown in fig. 3a, the second mosaic screen information of the upper monitoring center is 5 rows and 8 columns, the mosaic screen of the upper monitoring center is formed by splicing 40 display screens, and if the resolution of each display screen of the 40 display screens is 1080p, the second resolution information of the upper monitoring center is 1080 p.

The upper monitoring center can respectively calculate the total row pixel value of the spliced screen of the lower monitoring center to be 1440 and the total column pixel value to be 2560; the total pixel value of the row of the spliced screen of the upper monitoring center is 5400, and the total pixel value of the column is 15360.

The total pixel value of the row is the sum of pixel points of all screens in the vertical direction in the spliced screen, and the total pixel value of the column is the sum of pixel points of all screens in the horizontal direction in the spliced screen.

Then, the ratio of the total row pixel value of the spliced screen of the lower monitoring center to the total row pixel value of the spliced screen of the upper monitoring center is 1440/5400, the ratio of the total column pixel value of the spliced screen of the lower monitoring center to the total column pixel value of the spliced screen of the upper monitoring center is 2560/15360, and finally, the upper monitoring center can select the larger ratio 1440/5400 of the two ratios as the first scaling parameter for scaling the working scene operated by the lower monitoring center.

And S240, generating a working scene corresponding to the working scene operated by the lower monitoring center according to the first scene data and the first zooming parameter.

After the first scaling parameter is obtained by the calculation of the higher monitoring center, a working scene corresponding to a working scene operated by the lower monitoring center can be generated according to the first scene data sent by the lower monitoring center and the first scaling parameter.

For example, after the ratio 1440/5400 is selected by the upper monitoring center as the first scaling parameter for scaling the working scene operated by the lower monitoring center, the working scene corresponding to the working scene operated by the lower monitoring center can be generated according to the ratio 1440/5400 and the first scene data of the lower monitoring center.

Here, a description will be given of an example in which the working scene of the lower monitoring center is displayed in full screen on the mosaic screen of the lower monitoring center. When the working scene of the lower monitoring center is displayed in a full screen, the size of the working scene is the size of the spliced screen of the lower monitoring center, so that the upper monitoring center can scale the row total pixel value and the column total pixel value of the lower monitoring center according to the ratio 1440/5400, and the scene displayed in the spliced screen of the upper monitoring center after scaling is as shown in fig. 3b, where the block 330 represents the working scene obtained after scaling the working scene of the lower monitoring center. Therefore, the recovered working scene can be matched with the size of the spliced screen of the superior monitoring center.

In some examples, when the working scene of the lower monitoring center is not displayed in a full screen in the mosaic screen of the lower monitoring center, the upper monitoring center may zoom the working scene of the lower monitoring center according to the size information of the working scene in the scene data sent by the lower monitoring center and the first zoom parameter, so as to generate the working scene corresponding to the working scene operated by the lower monitoring center.

In some examples, a work scene frame may be preset in the upper monitoring center, and the upper monitoring center may generate a work scene corresponding to a work scene operated by the lower monitoring center based on the work scene frame. Therefore, the generated working scene corresponding to the working scene operated by the lower monitoring center can be avoided, and the interference to the working scene currently operated by the upper monitoring center can be avoided.

In some examples, after the previous monitoring center recovers to obtain the corresponding working scene, the recovered corresponding working scene may be displayed in a mosaic screen of the previous monitoring center in a centered manner.

For example, a difference value of pixels in a first row at the upper edge of the corresponding working scene obtained by the restoring and the upper edge of the spliced screen of the upper-level monitoring center may be the same as a difference value of pixels in a second row at the lower edge of the corresponding working scene obtained by the restoring and the lower edge of the spliced screen of the upper-level monitoring center, and a difference value of pixels in a first column at the left edge of the corresponding working scene obtained by the restoring and the left edge of the spliced screen of the upper-level monitoring center may be the same as a difference value of pixels in a second column at the right edge of the corresponding working scene obtained by the restoring and the right edge of the spliced screen of the upper-level monitoring center.

For example, the upper monitoring center may calculate a row pixel value and a column pixel value of the recovered working scene, then calculate a first difference between the row pixel value of the recovered working scene and a total row pixel value of the upper monitoring center, calculate a second difference between the column pixel value of the recovered working scene and a total column pixel value of the upper monitoring center, divide the first difference by 2 to obtain the first row pixel difference and the second row pixel difference, and divide the second difference by 2 to obtain the first column pixel difference and the second column pixel difference.

After the first row pixel difference and the first column pixel difference are obtained through calculation, the upper-level monitoring center may use the upper left corner of the spliced screen as the origin of coordinates of the spliced screen, calculate a row pixel incremental value downward according to the first row pixel difference, calculate a column pixel incremental value rightward according to the first column pixel difference, and use a pixel point corresponding to the row pixel incremental value and the column pixel incremental value as the origin of coordinates of the working scene. And the origin of coordinates of the working scene is positioned at the upper left corner of the working scene. Therefore, the upper monitoring center can display the recovered working scene in a centered manner.

According to the scene layout adjusting method provided by the embodiment of the invention, after first scene data sent by a lower monitoring center is received, second mosaic screen information and second resolution information of a local mosaic screen can be acquired, then a first zooming parameter for zooming a scene is calculated according to the first mosaic screen information, the first resolution information, the second mosaic screen information and the second resolution information in the first scene data, and further a working scene corresponding to a working scene operated by the lower monitoring center can be generated according to the first scene data and the first zooming parameter sent by the lower monitoring center. Therefore, when the video of the lower monitoring center is synchronized to the upper monitoring center, when the upper monitoring center reconstructs the scene according to the scene data sent by the lower monitoring center, the size of the scene can be reconstructed according to the splicing screen information and the resolution ratio information of the lower monitoring center, and the splicing screen information and the resolution ratio information of the upper monitoring center, so that the restored working scene can be matched with the size of the splicing screen of the upper monitoring center.

In some examples, the upper monitoring center may send a monitoring video call request to one lower monitoring center, or send a monitoring video call request to a plurality of lower monitoring centers, and to this end, an embodiment of the present invention further provides a possible implementation manner, as shown in fig. 4, which is a flowchart of a second implementation manner in which a scene layout adjustment method according to an embodiment of the present invention is applied to an upper monitoring center, and in fig. 4, the scene layout adjustment method may include:

s410, acquiring the identification information of the plurality of subordinate monitoring centers selected by the service personnel, and sending monitoring video calling requests to the plurality of subordinate monitoring centers according to the identification information of the plurality of subordinate monitoring centers.

In some examples, the above-mentioned upper monitoring center may be provided with a monitoring video call button, and the button corresponds to identification information of a plurality of lower monitoring centers, when a service person wants to view a monitoring video of a lower monitoring center, the monitoring video call button may be clicked at the upper monitoring center, the upper monitoring center may display the identification information of the plurality of lower monitoring centers, and then the service person may select among the identification information of the plurality of lower monitoring centers.

After the service staff selects, the higher monitoring center may obtain the identification information of the plurality of lower monitoring centers selected by the service staff, and may send a monitoring video call request to the plurality of lower monitoring centers according to the identification information of the plurality of lower monitoring centers.

For example, as shown in fig. 5a, a schematic diagram of a spliced screen of an upper monitoring center and a spliced screen of a lower monitoring center in a scene layout adjustment method according to an embodiment of the present invention is shown, where the spliced screen of the monitoring center represents the monitoring center. In fig. 5a, an upper monitoring center 500, a first lower monitoring center 510, a second lower monitoring center 520, a third lower monitoring center 530, and a fourth lower monitoring center 540 may be included. The service person may select a plurality of identification information among the identification information of the 4 lower monitoring centers in the upper monitoring center 500, for example, the service person selects the identification information of the first lower monitoring center 510, the identification information of the second lower monitoring center 510, and the identification information of the third lower monitoring center 530, and the upper monitoring center 500 may transmit a monitoring video call request to the first lower monitoring center 510, the second lower monitoring center, and the third lower monitoring center 530 according to the identification information of the first lower monitoring center 510, the identification information of the second lower monitoring center 510, and the identification information of the third lower monitoring center 530, respectively.

And S420, receiving a plurality of scene snapshot data sent by a plurality of subordinate monitoring centers.

In some examples, each lower monitoring center may obtain first scene data of a working scene running locally at the lower monitoring center after receiving the monitoring video call request sent by the upper monitoring center, and then perform snapshot processing on the scene data to generate scene snapshot data, and send the scene snapshot data to the upper monitoring center, so that the upper monitoring center may receive a plurality of scene snapshot data sent by a plurality of lower monitoring centers.

Each lower-level monitoring center corresponds to one scene snapshot data, and each scene snapshot data corresponds to one first spliced screen information and one first resolution information.

For example, after receiving a monitoring video call request sent by the upper monitoring center 500, the first lower monitoring center 510, the second lower monitoring center 520, and the third lower monitoring center 530 may obtain scene data of a locally running working scene, then perform snapshot processing on the scene data, generate scene snapshot data, and send the scene snapshot data to the upper monitoring center 500, so that the upper monitoring center 500 may receive the scene snapshot data sent by the first lower monitoring center 510, the second lower monitoring center 520, and the third lower monitoring center 530, respectively. The first subordinate monitoring center 510 corresponds to a scene snapshot data, the second subordinate monitoring center 520 corresponds to a scene snapshot data, and the third subordinate monitoring center 530 corresponds to a scene snapshot data.

And S430, acquiring second spliced screen information and second resolution information of the local spliced screen.

And S440, calculating a first zooming parameter for zooming the working scenes operated by the subordinate monitoring centers according to the first spliced screen information, the first resolution information, the second spliced screen information and the second resolution information.

In some examples, after the upper monitoring center receives scene snapshot data sent by a plurality of lower monitoring centers, a plurality of pieces of first mosaic screen information and a plurality of pieces of first resolution information may be obtained from the plurality of scene snapshot data. Each scene snapshot data corresponds to a first mosaic screen information and a first resolution information.

The superior monitoring center can calculate a first zooming parameter for zooming the working scenes of the operation of the subordinate monitoring centers according to the first spliced screen information, the first resolution information, the second spliced screen information and the second resolution information.

For example, if the above-mentioned upper monitoring center 500 receives the scene snapshot data sent by the first lower monitoring center 510 and the scene snapshot data sent by the third lower monitoring center 530, the first mosaic screen information and the first resolution information corresponding to the first lower monitoring center 510 and the first mosaic screen information and the first resolution information corresponding to the third lower monitoring center 530 may be obtained. And according to the first spliced screen information and the first resolution information corresponding to the first subordinate monitoring center 510, the first spliced screen information and the first resolution information corresponding to the third subordinate monitoring center 530, and the second spliced screen information and the second resolution information corresponding to the superior monitoring center 500, a first scaling parameter for scaling the working scene running in the first subordinate monitoring center 510 and the working scene running in the third subordinate monitoring center 530 is calculated.

In some examples, the plurality of first mosaic screen information in the scene snapshot data sent by the plurality of subordinate monitoring centers may be the same or different, and likewise, the plurality of first resolution information may be the same or different. And are not limited herein.

And S450, generating a working scene corresponding to the working scene operated by the subordinate monitoring center according to the first scene data and the first zooming parameter.

In the embodiment of the present invention, step S430 and step S450 may refer to step S220 and step S240 in the flowchart of the first implementation manner in which the scene layout adjustment method according to the embodiment of the present invention is applied to the upper monitoring center, and details are not described here.

By the embodiment of the invention, after receiving the plurality of scene snapshot data, the upper monitoring center can recover the working scene according to the same zoom parameter at the same time. Therefore, the working scenes of the plurality of subordinate monitoring centers can be displayed on the spliced screen of the superior monitoring center. Therefore, when working scenes of operation of a plurality of subordinate monitoring centers are displayed on the spliced screen of the superior monitoring center, the working scenes can be matched with the size of the spliced screen.

In a possible implementation manner of the embodiment of the present invention, the spliced screen of the upper monitoring center may be divided into a plurality of sub-spliced screens, for example, the spliced screen of the upper monitoring center is divided into 3 sub-spliced screens.

For this reason, the upper monitoring center may obtain the second splicing information and the second resolution information of each sub-spliced screen of the upper monitoring center.

In some examples, the resolution of each of the sub-tiles is the same for each sub-tile.

After the superior monitoring center acquires the second splicing information and the second resolution information of each sub-spliced screen, for each sub-spliced screen, the superior monitoring center can calculate a first zooming parameter corresponding to the sub-spliced screen, which is used for zooming a working scene in which at least one subordinate monitoring center operates, according to the first splicing screen information and the first resolution information of at least one subordinate monitoring center, and the second splicing screen information and the second resolution information of the sub-spliced screen.

Therefore, the corresponding display area can be set for the working scene of each subordinate monitoring center in the spliced screen of the superior monitoring center in advance, so that the working scene of the subordinate monitoring center can be displayed in the corresponding sub-spliced screen after being zoomed. Therefore, the zoomed working scene transmitted to the superior monitoring center can be orderly displayed in the spliced screen of the superior monitoring center.

For example, the above-mentioned superior monitoring center may calculate, according to the first spliced screen information and the first resolution information of the first inferior monitoring center 510, and the second spliced screen information and the second resolution information of one sub-spliced screen of the superior monitoring center, a first scaling parameter corresponding to the sub-spliced screen, which is used for scaling the working scene in which the first inferior monitoring center 510 operates.

On the basis of the method for adjusting a scene layout shown in fig. 4, an embodiment of the present invention further provides a possible implementation manner, as shown in fig. 6, which is a flowchart of a third implementation manner in which the method for adjusting a scene layout according to the embodiment of the present invention is applied to a superior monitoring center, and the method may include:

s610, obtaining the identification information of the plurality of subordinate monitoring centers selected by the service personnel, and sending monitoring video calling requests to the plurality of subordinate monitoring centers according to the identification information of the plurality of subordinate monitoring centers.

And S620, receiving a plurality of scene snapshot data sent by a plurality of lower monitoring centers.

S630, second spliced screen information and second resolution information of the local spliced screen are obtained.

And S640, calculating a row pixel total value and a column pixel total value corresponding to each piece of first mosaic screen information based on the plurality of pieces of first mosaic screen information and the plurality of pieces of first resolution information.

For example, assume that the first mosaic screen information in the scene snapshot data sent by the first subordinate monitoring center 510 and received by the upper monitoring center is 3 rows and 4 columns, the first resolution information is 720p, the first mosaic screen information in the scene snapshot data sent by the second subordinate monitoring center 520 is 4 rows and 2 columns, the first resolution information is 720p, the first mosaic screen information in the scene snapshot data sent by the third subordinate monitoring center 530 is 2 rows and 2 columns, and the first resolution information is 720 p.

The upper monitoring center may calculate a total value of row pixels corresponding to the first mosaic screen information of the first lower monitoring center 510 as 720 × 3 ═ 2160, and a total value of column pixels as 1280 × 4 ═ 5120, respectively; the first screen information of the second lower monitoring center 520 corresponds to a row pixel total value of 720 × 4-2880, a column pixel total value of 1280 × 2-2560, the first screen information of the third lower monitoring center 530 corresponds to a row pixel total value of 720 × 2-1440, and a column pixel total value of 1280 × 2-2560.

And S650, calculating a row pixel total value and a column pixel total value corresponding to the second spliced screen information based on the second spliced screen information and the second resolution information.

Assuming that the second screen information of the upper monitoring center 500 is 5 rows and 8 columns and the second resolution information is 1080p, the total row pixel value of the screen of the upper monitoring center 500 is 1080 × 5 — 5400 and the total column pixel value is 1920 × 8 — 15360.

And S660, determining a first scaling parameter for scaling the working scenes operated by the plurality of subordinate monitoring centers based on the row pixel total value and the column pixel total value corresponding to each piece of first spliced screen information and the row pixel total value and the column pixel total value corresponding to the second spliced screen information.

And S670, generating a working scene corresponding to the working scene operated by the subordinate monitoring center according to the first scene data and the first zooming parameter.

After the upper monitoring center calculates and obtains the total row pixel value and the total column pixel value corresponding to each piece of first spliced screen information and the total row pixel value and the total column pixel value corresponding to the second spliced screen information, a first scaling parameter for scaling the working scenes operated by the plurality of lower monitoring centers can be determined according to the total row pixel value and the total column pixel value corresponding to all pieces of first spliced screen information and the total row pixel value and the total column pixel value corresponding to the second spliced screen information.

For example, when the total value of row pixels corresponding to the second mosaic screen information is greater than the total value of column pixels corresponding to the second mosaic screen information, the working scenes of all the subordinate monitoring centers may be arranged according to rows. At this time, the following steps may be adopted to determine a first scaling parameter for scaling the working scenes operated by the plurality of lower monitoring centers:

and step A, selecting the maximum column pixel total value from the column pixel total values corresponding to the first spliced screen information. And calculating a first ratio of the maximum column pixel total value to the column pixel total value corresponding to the second mosaic screen information, and a second ratio of the total value of the row pixel total value corresponding to each first mosaic screen information to the row pixel total value corresponding to the second mosaic screen information.

For example, assuming that the above-described row pixel total value of the upper monitoring center 500 is greater than the column pixel total value, the column pixel total value 5120 of the third lower monitoring center 530 may be selected as the maximum column pixel total value among the column pixel total value 2560 of the first lower monitoring center 510 and the column pixel total value 5120 of the third lower monitoring center 530.

Then, a first ratio of the column pixel total value 5120 to the column pixel total value of the upper monitoring center 500 described above may be calculated, and a second ratio of the total value of the row pixels of the first lower monitoring center 510 and the row pixels of the third lower monitoring center 530 to the row pixels of the upper monitoring center 500 described above may be calculated.

And step B, determining the larger ratio of the first ratio and the second ratio as a first scaling parameter for scaling the working scenes operated by the plurality of subordinate monitoring centers.

After the first ratio and the second ratio are calculated by the upper monitoring center, the larger ratio of the two ratios can be determined as a first scaling parameter for scaling the working scenes operated by the lower monitoring centers.

For example, when the total row pixel value corresponding to the second mosaic screen information is not greater than the total column pixel value corresponding to the second mosaic screen information, all the working scenes of the subordinate monitoring centers may be arranged by columns, and at this time, the following steps may be adopted to determine a first scaling parameter for scaling the working scenes in which the plurality of subordinate monitoring centers operate:

and C, selecting the maximum row pixel total value from the row pixel total values corresponding to the first spliced screen information, calculating a third ratio of the maximum row pixel total value to the row pixel total value corresponding to the second spliced screen information, and calculating a fourth ratio of the total value of the column pixel total value corresponding to the first spliced screen information to the column pixel total value corresponding to the second spliced screen information.

For example, since the row pixel total value of the upper monitoring center 500 is 5400 and not more than the column pixel total value 15360 as described above, the row pixel total value 2880 of the second lower monitoring center 520 may be selected as the maximum row pixel total value among the row pixel total value 2160 of the first lower monitoring center 510, the row pixel value 2880 of the second lower monitoring center 520, and the row pixel total value 1440 of the third lower monitoring center 530.

Then, a third ratio of the row pixel total value 2880 to the row pixel total value 5400 of the upper monitoring center 500 may be calculated, and a fourth ratio of a total value 5120 of column pixels of the first lower monitoring center 510, a total value 2560 of column pixels of the second lower monitoring center 520, and a total value 10240 of column pixels of the third lower monitoring center 530 to a total value 15360 of column pixels of the upper monitoring center 500 may be calculated.

And D, determining the larger ratio of the third ratio and the fourth ratio as a first scaling parameter for scaling the working scenes operated by the plurality of subordinate monitoring centers.

After the third ratio 2880/5400 and the fourth ratio 10240/15360 are calculated by the upper monitoring center, the larger ratio of the two ratios can be determined as the first scaling parameter for scaling the working scenes in which the lower monitoring centers operate. For example, the fourth ratio 10240/15360 is determined as the first scaling parameter.

After determining the fourth ratio 10240/15360 as the first scaling parameter, the upper monitoring center may restore the working scenes corresponding to the working scenes of the three lower monitoring centers at the upper monitoring center according to the first scaling parameter, the working scene of the first lower monitoring center, the working scene of the second lower monitoring center, and the working scene of the third lower monitoring center, for example, the restored working scene 550 is an area shown by a bold black line in fig. 5 b. Here, the working scenes are displayed in a full screen on the mosaic screen of the corresponding lower monitoring center as an example.

In this embodiment of the present invention, steps S610 to S630 and step S670 may refer to a scene layout adjustment method applied to steps S410 to S430 and S450 in the flowchart of the second implementation manner of the upper monitoring center, which are not described herein again.

On the basis of the method for adjusting a scene layout shown in fig. 4, an embodiment of the present invention further provides a possible implementation manner, as shown in fig. 7, which is a flowchart of a fourth implementation manner in which the method for adjusting a scene layout according to the embodiment of the present invention is applied to a superior monitoring center, and the method may include:

and S710, acquiring the identification information of the plurality of subordinate monitoring centers selected by the service personnel, and sending monitoring video call requests to the plurality of subordinate monitoring centers according to the identification information of the plurality of subordinate monitoring centers.

And S720, receiving a plurality of scene snapshot data sent by a plurality of subordinate monitoring centers.

And S730, acquiring second spliced screen information and second resolution information of the local spliced screen.

And S740, constructing various layouts of working scenes operated by a plurality of subordinate monitoring centers on the basis of the plurality of first spliced screen information and the plurality of first resolution information.

For example, assume that the total value of row pixels corresponding to the first mosaic screen information of the first lower monitoring center 510 is 1440 and the total value of column pixels is 2560; the total value of the row pixels corresponding to the first mosaic screen information of the third subordinate monitoring center 530 is 2160, and the total value of the column pixels is 5120. A layout may be constructed according to the total row pixel value and the total column pixel value corresponding to the first mosaic screen information of the first lower monitoring center 510 and the total row pixel value and the total column pixel value corresponding to the first mosaic screen information of the third lower monitoring center 530.

For example, the plurality of layouts constructed may be a first layout and a second layout as shown in fig. 8a and 8b, wherein fig. 8a is the first layout of the first work scenario 810 and the second work scenario 820, and fig. 8b is the second layout of the first work scenario 810 and the second work scenario 820.

And S750, calculating a fifth ratio between the total value of the row pixels and the total value of the column pixels corresponding to each layout.

For example, for a first layout, the upper monitoring center 500 may calculate a total value of row pixels and a total value of column pixels to be 3600 and 5120 respectively corresponding to the first layout, and then may calculate a ratio of the total value of row pixels to the total value of column pixels to be 0.70;

for the second layout, the upper monitoring center 500 may calculate a total value of row pixels as 2160 and a total value of column pixels as 7680 corresponding to the second layout, respectively, and then may calculate a ratio of the total value of row pixels to the total value of column pixels as 0.28.

And S760, calculating a sixth ratio between the total row pixel value and the total column pixel value corresponding to the second spliced screen information based on the second spliced screen information and the second resolution information.

S770, selecting the layout corresponding to the fifth ratio with the smallest difference from the sixth ratio as the target layout.

For example, if the ratio of the first layout is 0.70, the ratio of the second layout is 0.28, and the sixth ratio corresponding to the second mosaic screen information is 0.35, the upper monitoring center may select the second layout as the target layout.

Therefore, when the target layout is selected, the shape of the target layout is close to that of the spliced screen of the superior monitoring center, so that when the working scene is recovered through the subsequent steps and displayed on the spliced screen of the superior monitoring center, the working scene can be matched with the shape of the spliced screen of the superior monitoring center as much as possible, and the utilization rate of the spliced screen of the superior monitoring center is improved.

S780, calculating a seventh ratio of the total row pixel value corresponding to the target layout to the total row pixel value corresponding to the second spliced screen information, and an eighth ratio of the total column pixel value corresponding to the target layout to the total column pixel value corresponding to the second spliced screen information.

After determining the target layout, the superior monitoring center may calculate a seventh ratio of the total line pixel value corresponding to the target layout to the total line pixel value corresponding to the second information of the tiled screen, and an eighth ratio of the total column pixel value corresponding to the target layout to the total column pixel value corresponding to the second information of the tiled screen.

For example, assuming that the total row pixel value of the upper monitoring center 500 is 5400 and the total column pixel value is 15360, the upper monitoring center may calculate that a seventh ratio of the total row pixel value corresponding to the target layout to the total row pixel value corresponding to the second mosaic screen information is 0.4, and an eighth ratio of the total column pixel value corresponding to the target layout to the total column pixel value corresponding to the second mosaic screen information is 0.5

And S790, determining the larger ratio of the seventh ratio and the eighth ratio as a first scaling parameter for scaling the working scenes operated by the plurality of lower-level monitoring centers.

After the seventh ratio and the eighth ratio are obtained through calculation by the upper monitoring center, a larger ratio of the seventh ratio and the eighth ratio may be determined as a first scaling parameter for scaling the working scenes in which the plurality of lower monitoring centers operate.

For example, the upper monitoring center 500 may determine the eighth ratio 0.5 as the first scaling parameter after calculating the seventh ratio 0.4 and the eighth ratio 0.5.

And S7910, taking the target layout as a scene layout corresponding to working scenes operated by a plurality of subordinate monitoring centers, and scaling the first scene data by adopting a first scaling parameter.

After determining the first scaling parameter, the upper monitoring center may use the target layout determined in the foregoing step as a layout of a working scene in which a plurality of lower monitoring centers operate, and then may scale scene data sent by each lower monitoring center by using the first scaling parameter.

In some examples, the scaling of the scene data may be scaling of size data used for constructing the working scene in the scene data.

S7920, generating a working scene corresponding to the working scenes in which the plurality of lower level monitoring centers operate according to the scene layout and the scaled first scene data.

After the upper monitoring center zooms the scene data sent by each lower monitoring center, the upper monitoring center can perform layout according to the scene layout when generating the working scene by using the zoomed scene data, so that the working scene corresponding to the working scene operated by a plurality of lower monitoring centers can be generated.

Therefore, a plurality of working scenes displayed on the spliced screen of the superior monitoring center can be matched with the size of the spliced screen. The utilization rate of the spliced screen is improved.
