Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

An embodiment of the present disclosure provides an image management method, applied to a foreground device, as shown in fig. 1, including the following steps:

Step 101, acquiring a first operation instruction.

The first operation instruction is used for indicating to establish reference connection between the target acquisition end node and the target receiving end node; the first operation instruction carries identification information of a target acquisition end node and identification information of a target receiving end node.

For example, the control interface of the foreground device displays a plurality of collection end node icons and a plurality of receiving end node icons, and the administrator may select a target collection end node and a target receiving end node on the control interface of the foreground device and input an operation event for establishing a reference connection between the target collection end node and the target receiving end node, so that the foreground device generates a first operation instruction according to the operation event, the target collection end node and the target receiving end node.

Step 102, sending the first operation instruction to a background device, so that the background device responds to the first operation instruction, establishes reference connection between the target acquisition end node and the target receiving end node, draws a reference connection icon, and sends a first target image to a foreground device.

Wherein the first target image includes the reference connection icon; the reference connection is a mapping relationship between the target acquisition end node and the target receiving end node.

When the foreground device obtains the first operation instruction, the foreground device sends the first operation instruction to the background device, the background device analyzes the received first operation instruction to obtain identification information of the target acquisition end node and identification information of the target receiving end node, a mapping relation between the identification information of the target acquisition end node and the identification information of the target receiving end node is stored, namely, the mapping relation is equal to that of establishing reference connection between the target acquisition end node and the target receiving end node, then an icon of the target acquisition end node is found according to the identification information of the target acquisition end node, an icon of the target receiving end is found according to the identification information of the target receiving end node, then a reference connection icon between the target acquisition end node and the target receiving end node is drawn on a background image, and finally a first target image drawn with the reference connection icon is sent to the foreground device.

It can be understood that the first target image includes, in addition to the reference connection icon, an icon of the target acquisition end node and an icon of the target receiving end node, so that an administrator can conveniently view the icons of the nodes and the reference connection icon.

It should be noted that, the reference connection is not actually connecting the target acquisition end node with the target receiving end node, but only establishing a corresponding relation between the identification information of the target acquisition end node and the identification information of the target receiving end node; the role of the reference connection icon is simply to let the administrator see if the connection is correct as such now.

Step 103, receiving and displaying the first target image.

For example, when the foreground device receives the first target image, the first target image is displayed on the control interface, so that an administrator can conveniently check a reference connection icon between the target acquisition end node and the target receiving end node in the first target image to determine whether the connection is correct.

An embodiment of the present disclosure provides an image management method, applied to a foreground device, as shown in fig. 2, including the following steps:

step 201, obtaining a third operation instruction.

Wherein the third operation instruction is used for indicating to establish a target node; the third operation instruction carries type information of the target node and address information of the target node; the target node comprises the target acquisition end node and/or the target receiving end node.

For example, the administrator may input address information and type information of the target node on the control interface, and then input an operation event for establishing the target node, so that the foreground device generates the third operation instruction according to the operation event, the address information and the type information of the target node.

It should be noted that, when the number of the target nodes is greater than one, the third operation instruction also carries name information of the target nodes, so that an administrator can distinguish each target node conveniently.

Step 202, sending the third operation instruction to the background device, so that the background device establishes the target node, draws a target node icon corresponding to the target node, and sends a third target image to the foreground device.

Wherein the third target image includes the target node icon; the target node icon is different from the reference connection icon.

When the foreground device acquires the third operation instruction, the foreground device sends the third operation instruction to the background device, the background device analyzes the received third operation instruction to obtain address information and type information of the target node, and the target node is built according to the address information and the type information of the target node; for example, if the address information of the target node is 172.172.10.1 and the node type is the acquisition end, the background device sets the camera with the website of 172.172.10.1 as the target acquisition end node and generates the identification information of the target acquisition end node as 1; after the background equipment establishes the target node, the background equipment also needs to draw a target node icon of the target node on the background image, and finally, a third target image containing the target node icon is sent to the foreground equipment; for example, if the target node is a target acquisition end node, then a target acquisition end node icon may be drawn on the background map.

The background equipment stores node information of each target node in advance, wherein the node information comprises names of the target nodes, identification information of the target nodes, address information of the target nodes, type information of the target nodes and the like, the address information of the target nodes can be a network address, a longitude and latitude address and the like, in a word, one node can be uniquely determined in an actual scene, and the type information of the target nodes comprises an acquisition end, a receiving end and the like; in addition, when a cursor on a background image of the control interface moves to a target node icon, and an administrator clicks a mouse, the background device can capture a mouse typing event, determine a target node according to the position of the mouse, further obtain node information of the target node, send the node information to the control interface, generate a popup according to the received node information by the control interface, and display the popup near the target node on the background image. For example, when the cursor is moved onto the target node, the background device pops up a popup window, and the information displayed in the popup window includes node identification information: 1, node name: sentry 1, node address: 172.172.10.1, node type: and a collection end.

Step 203, receiving and displaying the third target image.

For example, when the foreground device receives the third target image, the third target image is displayed on the control interface, so that an administrator can conveniently view the target node icon on the control interface.

And 204, acquiring a target thumbnail.

Specifically, as shown in fig. 3, the acquisition of the target thumbnail may be achieved by:

Step 2041, obtain the target subscription instruction.

The target subscription instruction is used for indicating to acquire a thumbnail of the image information acquired by the target acquisition end node; the target subscription instruction carries the identification information of the target acquisition end node.

For example, the foreground device configures each node, as shown in fig. 4, where the configuration content includes editing a node, deleting a node, centrally displaying on a map, subscribing a thumbnail, canceling a subscription thumbnail, and the like, and the administrator may click on a target acquisition end node icon to select the subscription thumbnail, so that the foreground device obtains an operation event requiring the subscription thumbnail, obtains identification information of the target acquisition end node, and generates a target subscription instruction according to the identification information of the target acquisition end node and the operation event.

Step 2042, sending a target subscription instruction to the background device, so that the background device obtains a target thumbnail, and sending the target thumbnail to the foreground device.

When the foreground device acquires the target subscription instruction, the foreground device sends the target subscription instruction to the background device, the background device analyzes the received target subscription instruction to obtain the identification information of the target acquisition end node, acquires the corresponding target thumbnail according to the identification information of the target acquisition end node, and sends the target thumbnail to the foreground device.

Step 2043, receiving the target thumbnail.

Step 205, displaying the target thumbnail in an image preview frame.

For example, when receiving the target thumbnail, the foreground device displays the target thumbnail in an image preview frame, so that an administrator can conveniently view the acquired image.

In addition, because the thumbnail has low requirement on real-time performance, in order to reduce the workload of the image management system, part of the encoded data can be collected and decoded from the encoded data sent by the target collection end node, for example, the target collection end node sends the encoded data to the target decoding end in real time, and the target decoding end obtains the encoded data of one frame of thumbnail from the encoded data every 5 minutes, and the target thumbnail of the frame is obtained after decoding. In addition, the connection established between the target decoding end and the target acquisition end node does not have a reverse control function.

It should be noted that, the image preview frame may simultaneously display thumbnails of multiple target acquisition end nodes, where each thumbnail of the target acquisition end node is displayed in a separate window. That is, three windows are arranged in the image preview frame, and the thumbnails of the three target acquisition end nodes are respectively displayed.

Step 206, obtaining a first operation instruction.

Step 207, sending the first operation instruction to a background device, so that the background device responds to the first operation instruction, establishes a reference connection between the target acquisition end node and the target receiving end node, draws a reference connection icon, and sends a first target image to a foreground device.

As an example, as shown in fig. 5, it is a node icon of two nodes set on a background diagram of a control interface of the image management system of the present disclosure, and a reference connection between the two node icons, where the color and the line type of the reference connection icon may be preset, for example, the color of the reference connection icon is green, and the line type of the reference connection icon is a dotted line; in addition, in practical application, a round camera icon can be used as an acquisition end node icon, a display icon is used as a receiving end node icon, and the device can be specifically set according to requirements; the node icons are of one preset color when selected and of another preset color when unselected, so that the node icons are conveniently distinguished from each other and the unselected node icons are conveniently distinguished.

Step 208, receiving and displaying the first target image.

Step 209, obtaining a second operation instruction.

Wherein the second operation instruction is configured to instruct application of the reference connection; and the second operation instruction carries the identification information of the reference connection.

For example, when the administrator determines that the reference connection between the target acquisition end node and the target receiving end node and the overall setting and layout are correct according to the reference connection icon, the administrator may click on the icon of the target acquisition end node or the icon of the target receiving end node, and click on the application reference connection control in the popup window when the popup window related to the reference connection is popped up, so that the foreground device obtains an operation event of the application reference connection, and generates a second operation instruction according to the operation event.

As shown in fig. 6, the popup window related to the reference connection may include functions such as reference connection disconnection, reference connection, node deletion, reference connection saving, and reference connection application, where the reference connection saving is to save the current reference connection state, and the next time the configuration may be continued.

The identification information of the reference connection is generated when the reference connection is established.

When determining that the connection between the target collecting end node and the target receiving end node is wrong according to the reference connection icon, the administrator may input a wrong operation instruction, where the wrong operation instruction may carry the identification information of the target collecting end node and the identification information of the target receiving end, and the identification information of the new target receiving end node, so that the foreground device sends the wrong operation instruction to the background device, the background device deletes the reference connection between the target collecting end node and the target receiving end, and establishes the reference connection between the target collecting end node and the new target receiving end node according to the identification information of the target collecting end node and the identification information of the new target receiving end node.

It should be noted that, the error operation instruction may also carry the identification information of the target acquisition end node and the identification information of the target receiving end, and the identification information of the new target acquisition end node, so that the foreground device sends the error operation instruction to the background device, the background device deletes the reference connection between the target acquisition end node and the target receiving end, and establishes the reference connection between the new target acquisition end node and the target receiving end node according to the identification information of the new target acquisition end node and the identification information of the target receiving end node.

Step 210, sending the second operation instruction to the background device, so that the background device responds to the second operation instruction, establishes communication connection between the target acquisition end node and the target receiving end node, draws a communication connection icon corresponding to the communication connection, and sends a second target image to the foreground device.

Wherein the second target image includes the communication connection icon.

When the foreground device obtains the second operation instruction, the foreground device sends the second operation instruction to the background device, the background device analyzes the received second operation instruction to obtain identification information of reference connection, the identification information of the target acquisition end node and the identification information of the target receiving end node are further searched according to the identification information of the reference connection, further, the icon of the target acquisition end node and the icon of the target receiving end node are searched according to the identification information of the target acquisition end node and the identification information of the target receiving end node, real communication connection between the target acquisition end node and the target receiving end node is established, the communication connection icon between the icon of the target acquisition end node and the icon of the target receiving end node is drawn, and finally, a second target image containing the communication connection icon is sent to the foreground device.

It can be understood that the second target image includes, in addition to the communication connection icon, an icon of the target acquisition end node and an icon of the target receiving end node, so that an administrator can conveniently view the icons of the nodes and the communication connection icon; the communication connection is a real connection, and the reference connection only stores the mapping relation between the identification information of the target acquisition end node and the identification information of the target receiving end node; in addition, the communication connection icon is also different from the reference connection icon, and the communication connection icon may be a solid line of a preset color, and the reference connection icon may be a broken line of another preset color.

Step 211, receiving and displaying a second target image.

An embodiment of the present disclosure provides an image management method applied to a background device, as shown in fig. 7, including the following steps:
