Detailed Description
The technical means of the present invention will be described in further detail with reference to specific embodiments. It should be understood that the detailed description and specific examples, while indicating the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
FIG. 1 is a block diagram of a system according to an embodiment of the present invention. The system comprises a server 1, a splicing controller 2, n clients 31, 32 … … 3n, a screen 4, a collection terminal 5 and an input device 6. The number n of the clients may be 1 or 2 or more.
The screen 4 may be composed of one screen, or at least two sub-screens may be spliced together by the splicing controller 2 (or called video splicing controller or large screen splicing controller, etc.), and set according to size requirements. The sub-screens spliced together may be spatially adjacent to each other or may be spatially separated from each other, for example, may be separated by a certain distance. Here, the multi-screen splicing controller may also enable at least two sub-screens to respectively display different client contents, or the same client content, or may also enable at least two sub-screens to display different pictures, where the different pictures are spliced into a complete client content or picture.
The splicing controller 2 may be implemented by hardware, or may be implemented by software in the server 1, and since the splicing controller is widely known to those skilled in the art, the description thereof is omitted here.
The content in the client 31-3n should be modifiable and editable through an input device such as a mouse, for example, a cursor may be moved to a certain position in the content through the mouse, and then corresponding characters may be typed; alternatively, a certain file or folder may be double-clicked by a mouse to open the corresponding file or folder, etc.
The input device 6 may be a mouse, a tablet, a joystick, a touchpad, or other position input devices.
The capturing end 5 may be any type of computer, such as a desktop computer, a notebook computer, a tablet computer, etc., or any processing device capable of capturing an input position of the input device 6. The acquisition end 5 is connected with the input device 6 through a man-machine interface and is used for acquiring input coordinates of the input device 6.
For convenience of explaining the technical solution of the present invention, the following embodiments will be described by taking a mouse as an example of an input device. However, it will be understood by those skilled in the art that the technical solutions of the present invention include, but are not limited to, a mouse, and any alternative to the above-mentioned input device 6 should be included in the scope of the present invention.
In the embodiment shown in fig. 2, it is assumed that the control system of the present embodiment includes 4 clients 31, 32, 33, 34, and the displayed contents are a, b, c, d; wherein, the screen 4 may include 8 sub-screens 41, 42, 43, 44, 45, 46, 47, 48, and the content of each client is displayed in the content window of the sub-screen according to a predetermined layout in the splicing controller 2;
for example, the display window on the sub-screen 41 in the first row and the first column, the display window on the sub-screen 44 in the second row and the first column, are full of the content of the client 31, such as the two-dimensional map a of a certain region, the display window on the sub-screen 42 in the second row and the second column, the sub-screen 43 in the first row and the third column, the sub-screen 45 in the second row and the third column, and the sub-screen 46 in the second row and the third column, are 4 blocks of the content of the client 32, such as the three-dimensional map b of a certain region, the display window 47 on the sub-screen in the first row and the fourth column, such as the monitor picture b of the camera, the display window on the sub-screen 48 in the second row and the fourth column, such as the video picture d, and the like.
Those skilled in the art will appreciate that the number of clients and sub-screens and the layout of the content window can be set as desired, and are not limited to the above example.
The workflow of the control system according to the embodiment of the present invention is described in detail below with reference to the method flowchart of fig. 4.
Initially, when the user wants to manipulate the content d, the user uses the mouse 6 to input coordinates, such as a cursor position, and inputs manipulation instructions, such as moving, double-clicking, single-clicking, dragging, etc., at a corresponding position of the screen 4 where the content d is to be manipulated;
then, in step S101, the acquisition end 5 acquires input coordinates of the mouse, for example, (xs, ys), and a control instruction, and sends the input coordinates and the control instruction to the server 1;
then, in step S102, the server 1 converts the received mouse coordinates into mapped mouse coordinates, and converts the coordinate ranges of the respective content windows in the screen 4 into mapped coordinate ranges;
specifically, the server 1 converts the received mouse coordinates into mapped mouse coordinates, and may convert the acquired mouse coordinates (Xs, Ys) into a unified mapped mouse coordinate (Xs, Ys) of a mapped screen according to the resolution of the screen of the acquisition end 5. The mapping screen may be coordinates of any resolution screen, and the present invention may be implemented as long as the screen coordinates of the acquisition end 5 and the screen 4 are converted into coordinates of uniform screen resolution. It should be noted that in order to guarantee an effective screen resolution, the resolution of the mapping screen coordinates should be no less than the resolution of the maximum resolution screen of the acquisition end 5, screen 4.
For example, assume that the screen resolution length of the acquisition terminal 5 is (a × b) and the screen resolution is (m × n) mapped. The calculation formula may be Xs ═ m/a, Ys ═ Ys ×/b. For example, assuming that (a × b) is (1920 × 1080) and the mapping screen resolution is (65535), the mapping mouse coordinates (Xs, Ys) are: xs 65535/1920, Ys 65535/1080;
the conversion of the coordinate range of each content window in the screen 4 into the mapping coordinate range is realized by the following steps:
step S1021, the stitching controller 2 sends the screen resolution of the screen 4 to the server 1, e.g., (p, q), e.g., (3840 × 2160); the server 1 receives the screen resolution and calculates the length-height ratio of the screen resolution of the screen 4 to the mapping screen resolution (m, n), namely (p/m, q/n);
then, in step S1022, the server 1 obtains the coordinate range of the content window of each client, such as the length and the height of the content window and at least one vertex coordinate (for example, the initial vertex coordinate of the upper left corner) of the content window, according to the screen layout preset in the splicing controller 2;
for example, the screen layout preset in the splice controller 2 is such that the content d of the client 34 is displayed in the sub-screen 48, the coordinates of the top left vertex of the content window are (xa0, ya0), and the window length L is high H; the server 1 converts the coordinates of the top left vertex (Xa0, Ya0) into the content window mapping coordinates in the mapping screen resolution (p, q) according to the screen resolution ratio, that is, Xa0 ═ Xa0 × p/m, Ya0 ═ Ya0 × q/n;
then, in step S103, the server 1 determines, according to the mapping mouse coordinate and the coordinate range of the mapping content window, a client to which the content of the mouse coordinate belongs;
specifically, the server 1 determines which client the content operated by the user belongs to according to the mapping mouse coordinates (Xs, Ys), at least one vertex mapping coordinate value (Xa0, Ya0) of each content window in the screen layout and the length-height value H, L of the content window, and then sends the mouse coordinates to the corresponding client;
for example, if the mapping mouse position is located in the window of the content d, the server 1 determines, according to the initial vertex coordinate and the length value of the window of the content d, that the mapping mouse position is located at the position corresponding to the content d, and the content d belongs to the client 34, and then sends the mouse coordinate to the client 34, as shown in fig. 3;
then, in step 104, a client, such as the client 34, where the content is to be manipulated receives the mapping coordinates and the manipulation information of the mouse sent by the server 1, and the client converts the mapping coordinates of the mouse into local coordinates;
wherein, the step 104 specifically comprises the following steps:
and converting (65535) the mapping coordinates of the mouse into coordinates of a screen, so as to obtain the local coordinate position of the mouse at the client.
It will be understood by those skilled in the art that, since the screen is divided into 65535 × 65535 units uniformly by default in the mouse coordinate system of the windows system API function, based on the above principle, the present invention may preferably choose to set the resolution of the mapping screen to (65535), so that the server 1 only needs to convert the coordinates of the capturing end 5 and the screen 4 once, and does not need to convert the coordinates of the screen of the client.
Then, in step 105, the client responds to the corresponding location content according to the manipulation information, and then displays the corresponding content.
For example, a user clicks a certain content, such as a file, in a content window in the screen 4 through a mouse, the file is selected through the mouse at this time, and then the user double-clicks the file, so that the client where the file is located performs double-clicking on the file and displays the file in the screen 4;
the user can also drag a content window of the screen and other control actions by long pressing the left mouse button, and the client at which the dragged window is located executes the dragging action and displays the dragging action in the screen 4.
The control actions are similar to those of a common mouse and are not described again.
Example two
As shown in fig. 5, the input device 6 in the second embodiment of the present invention further includes a data input device, such as a keyboard (not shown). The keyboard is not different from a conventional keyboard, and the acquisition end 5 acquires input coordinates and control information of the position input device and key values of the keyboard at the same time and sends the input coordinates and the control information and the key values to the server 1;
the server 1 sends the input coordinates or the mapping coordinates to the client to which the content of the coordinates belongs according to the method described in the first embodiment, and also sends the keyboard value of the keyboard to the client, so that the client operates in the corresponding content according to the keyboard value.
For example, as shown in fig. 5, if a user wants to operate the editable map software in a content window by a mouse, for example, to type information to be labeled, such as "altitude", "distance", etc., the cursor of the mouse can be moved to the position of the map to be typed and a click action is performed; the client 34 responds according to the click action information, for example, a typing window is opened, and then a label name is typed in through a keyboard, at this time, the server 1 sends the key value of the keyboard collected by the collecting terminal 5 to the corresponding client 34, and then the client 34 responds according to the keyboard input.

The integrated module can be realized in a form of hardware, and can also be realized in a form of a functional module of software. The integrated unit, if implemented in the form of a software functional module and sold or used as a stand-alone product, may also be stored in a computer readable storage medium, such as a read-only memory, a magnetic or optical disk, or the like.
