Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.
For ease of understanding, referring to fig. 1, an embodiment of a full wall labeling method for a distributed cluster processor provided herein includes:
Referring to fig. 3, mapping the full wall area to the annotation client is to facilitate subsequent annotation operations, where the mapped annotation area is mainly expressed by an annotation coordinate, and similarly, the full wall area also includes the full wall coordinate, and the essence of mapping is a coordinate conversion process, that is, the coordinate of the full wall area of the large spliced screen is converted into the coordinate of the annotation client, so that the object to be annotated on the large spliced screen also has a corresponding position in the coordinate system of the annotation client. For convenience of description, the mapping operation is performed by using a mapping manner with a height and a width enlarged by 4 times, which is only an example and is not limited herein.
And 102, sequentially marking the objects to be marked in the marking area through the marking client to obtain current marking information, wherein the current marking information comprises current marking coordinates.
The marking is an operation on an object to be marked in the large spliced screen, the object to be marked is also located under the corresponding marking coordinate in the marking client after the coordinate is converted, marking can be completed on the object to be marked by adopting a preset marking method based on the coordinate, and current marking information of the marking object is obtained.
The method for labeling the object to be labeled in the labeling area by the labeling client can be as follows: when the signal host has the marking function, the writing and marking can be directly realized through the signal host with the marking, and the marked signal is displayed on the splicer. Or when the signal host does not have the marking function, a video signal coding box (such as an HIPC coding box, a VIS coding box and the like) is added in the middle link of signal transmission (the signal is displayed in front of the splicing wall), and the marking handwriting is combined in the video stream of the video signal coding box and then displayed on the splicing wall. However, the two schemes only can realize signal source marking, and cannot realize the effect wall marking of the whole splicing. Therefore, the labeling server can also be used for sending the labeling handwriting to the desktop of the host machine for drawing by using the current default desktop (such as a multi-screen processor) of the high-resolution host machine, so that the labeling of the whole desktop is realized, the desktop is projected to the wall, the whole-wall labeling is realized, but the labeling can only be carried out on the bottom desktop, and when a signal window exists on the display desktop, the labeling handwriting can be blocked, and the labeling effect is influenced. Or respectively acquiring the positions of the signal window and the desktop label information on the spliced wall; calculating the position of the overlapping part of the signal window and the desktop labeling information and the labeling information corresponding to the overlapping part according to the position of the signal window and the position of the desktop labeling information; and correspondingly displaying the marking information corresponding to the overlapping part on the signal window according to the position of the overlapping part, and displaying the signal window and the desktop marking information on the spliced wall. The labeling methods given above can be arbitrarily selected according to actual requirements, and are not limited herein.
And 103, displaying the current labeling information according to the preset full-wall layout information through a distributed splicing processor based on the current labeling coordinate, wherein the distributed splicing processor comprises a plurality of processor nodes.
Further, step 103 includes:
converting the current labeling coordinate into a current full-wall coordinate, and sending the current full-wall coordinate to the distributed splicing processor;
carrying out region splitting on the marked object corresponding to the current marking information according to the received current full wall coordinate through a distributed splicing processor to obtain split object information;
and distributing the split object information to each processor node through the distributed splicing processors for marking and displaying.
Referring to fig. 4 and 5, since the actual control of the large mosaic screen is in the distributed mosaic processor, the current annotation information after annotation is still sent to the distributed mosaic processor for command control, so as to display the annotation information on the large mosaic screen. Obviously, before that, the coordinates need to be reversely converted, that is, the current labeling coordinates are reversely mapped according to the initial coordinate mapping mode, and converted into the full-wall coordinates of the full-wall area of the large spliced screen, that is, the current full-wall coordinates, and then the labeling object with the current coordinate information and the current full-wall coordinates is sent to the distributed splicing processor. The distributed splicing processor can split the region of the labeled object, namely, the curve, the rectangle and the circle in fig. 4, according to the pre-initialized mapping rule, and distribute the information to the corresponding processor nodes according to the full-wall layout information, and each processor node performs object description and labeled information display according to the information of the split object, the former process is the prior art, and is not described herein, and the process of displaying the labeled information on the large splicing screen is mainly emphasized in this embodiment.
Specifically, refer to FIG. 4, wherein curve A is a combination of (A.1-0.1, A.0-1.1, A.0-2.1, A.1-1.1, A.1-0.2, A.1-1.2, and A.1-2.2); the rectangle B is formed by combining (B.0-0.1, B.0-1.1, B.0-2.1 and B.0-1.2); the round C is formed by combining (C.0-2.1, C.0-3.1, C.1-3.1 and C.1-2.1).
Further, step 103, before, further comprising:
and establishing preset full-wall layout information in each processor node of the distributed splicing processor, wherein the preset full-wall layout information comprises IP addresses and resolution.
Further, step 103, before, further comprising:
and carrying out initialization splitting mapping processing on the object to be marked based on the full wall area and preset full wall layout information.
Referring to fig. 5, the distributed tiled processor cluster includes a plurality of processor nodes, each node is responsible for display control of a part of tiled screen area or a certain tiled screen area, and before the distributed tiled processor is used for display, the essence of establishing preset full-wall layout information for each node in the distributed processor cluster is to divide different areas of a large tiled screen into different node controls, so as to realize distributed tiled screen control; therefore, the preset full wall layout information needs to include an IP address, and since the splicing areas are all controlled by the distributed processors, the condition that the resolution is not uniform can be satisfied, so that the compatible range of the splicing screen is expanded, more execution possibilities are provided, and the resolution 1920 × 1080 provided by the embodiment is only an example. In addition, the preset full-wall layout information may include, in addition to information such as an IP address and a resolution, a coordinate position of the mosaic screen, for example, (0, 0), and a region corresponding node, for example, node 1; these may be added according to actual needs, and are not limited herein.
