Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. 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.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined or explained in subsequent figures.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
In the prior art, a network keyboard is usually required to be matched with a large screen to call a live image picture stored in a management device by a monitoring device, and the large screen displays a graphical user interface and a live image corresponding to the monitoring device. The network keyboard is generally used for controlling the live picture to be displayed and switched on a large screen and controlling the direction rotation and the lens expansion and contraction of a monitoring device (such as a network camera). With the increasing of the service functions, the complexity of the graphical user interface is also increased, and a pure network keyboard cannot meet the operation of some complex scenes, so that the operation of configuration/management and the like needs to be finished by a user through a mouse. Referring to fig. 1, fig. 1 shows a system architecture diagram of a mouse 600 and a network keyboard 100, which are typically deployed separately for addressing operations in complex scenarios. In the system architecture, the network keyboard 100 and the display device 200 are usually deployed in a monitoring room, the monitoring device 500 and the management device 300 are usually deployed at a remote location, the monitoring device 500 stores monitoring screen information in the management device 300 through the switch 400, wherein the network keyboard 100 may interact with the management device 300 through a network, if a local graphical interaction interface of the monitoring device 500 is to be operated, the mouse 600 needs to be connected to the management device 300, and if a network client is to be operated, the PC 700 (including a display screen, a mouse and a keyboard) needs to be additionally configured to interact with the management device 300 through the network. In this embodiment, the management device 300 is taken as a management device in a video monitoring network as an example for explanation, and may be a network monitoring management device or a VMS (video management system) server.
When the corresponding interface operation needs to be displayed in cooperation with the display device 200, most of the interface operations need to be performed through the mouse 600, and some of the interface operations need to be performed by using the keys of the network keyboard 100 in cooperation with the joystick. However, if the corresponding interactive interface operation is performed through the mouse 600, the mouse 600 needs to be externally connected; if a large amount of configuration operations are carried out by using the keys and the rocker, the problem of inconvenient control in operation exists. In addition, in the scenario shown in fig. 1, if the monitoring room is far from the management device 300, and the mouse cannot be directly connected to the monitoring room through a wired or wireless manner, an additional PC 700 needs to be deployed in the monitoring room, otherwise, the display 800 needs to be separately configured at the management device 300. When local configuration is performed, special maintenance personnel are required to go to the site where the remote equipment is located to perform configuration maintenance.
In order to overcome the above-mentioned drawbacks of the prior art, the inventors have studied to provide the following embodiments to provide a solution.

And superposing cursor information corresponding to the mouse state change information on a corresponding position of the image to be displayed according to the coordinate information operated by the mouse 600.
In step S160, the management device 300 sends the superimposed image to be displayed to the display device 200 for displaying.
In this embodiment, when the cursor state information is the movement information of the cursor, the display device 200 displays the moving track of the cursor on the image screen.
When the cursor information is click information of the cursor, an animation in which the cursor is clicked on the image screen is displayed on the display device 200.
When the cursor information is the scroll information, the image frame on the display device 200 moves along the scroll direction.
The above process of converting the mouse state change information into the cursor state information and the process of displaying the cursor state information in an overlapping and overlapping manner are the same as the prior art, and will not be described herein too much.
