Detailed Description
Throughout this application, references to network implementations are intended to encompass both wired and wireless network connections implemented through necessary firmware or software, such as switches, routers, and the like, as well as wired and wireless network connections implemented through some intermediary, such as servers or other computers. Furthermore, since the transmission of signals over a network (including encoding the signals into a video stream of a certain format, such as an rtsp stream, etc.) is well known, the encoding and transmission of this part will not be explained in detail in this application.
Fig. 1 schematically shows a flowchart of a plot processing method according to a first embodiment of the present invention.
A plot processing method according to a first embodiment of the present invention includes:
s1, receiving an image from a signal source, and drawing the image in a window;
s2, plotting the image;
s3, storing the plotting information and the sub-scene information; the sub-scene information comprises window position information and window signal information, the window signal information comprises a network stream address of the image, wherein the plot information and the sub-scene information are suitable to be re-read to enable loading of the image and loading of the plot.
This first embodiment is described in detail below.
The computer is connected with other signal sources through a network, and the signal sources can comprise computers, mobile phones, cameras and other devices.
The computer receives the video frame from the signal source and draws the image of the video frame on a window of the computer. In this process, the window may be formed at a different position and the image may be displayed in the window at a different position by the drag operation. In some cases, the server may be notified according to the scene information to send a windowing command to the local client (the computer), and the computer may then perform windowing in response to the command and draw an image within the window. The foregoing list of cases enables the image of the signal source to be finally drawn in the window, and is also within the scope of the present application. The computer then further plots the image drawn on the window in response to the customer's plotting operation, including drawing lines on the image, adding geometry diagrams, flow charts, annotating, adding text, coloring, etc., as shown schematically in FIG. 2a, and labels or buttons for plotting, arrows, drawing lines, graphics, saving labels or buttons, and possibly adding labels or buttons for screen recording, dismissing, clearing, etc.
For the plotted image, the computer saves the corresponding sub-scene information (or called node information) and the plotting information according to the saving operation (such as click saving) of the client. The sub-scene information includes window signal information and window position information. The window signal information includes a network stream address of the image. The plot information and the sub-scene information are adapted to be re-read to enable loading of the image (by network stream address in the window signal information of the sub-scene information) and loading of the plot on the image. The network flow address may comprise, for example, an rtsp flow address. According to the actual control requirement on the signal source and the control requirement on a plurality of images in one signal source or a plurality of images in a plurality of signal sources, the consideration of different screen resolutions and the like in the environment is implemented, and the window signal information can further comprise information such as a signal source name, a signal source resolution, a signal source IP address and the like. The window position information may include absolute position information and/or relative position information of the window in the display screen. The plotting information comprises line information, geometric shape information, flow chart information, marking information, character information and color information. Here, by way of example only, other plot information is within the scope of the present invention. Further, the computer may also update and save the sub-scene information in real time according to the generation, movement, enlargement, reduction, and the like of the window for displaying the image, and update and save the plot information in real time according to the generation of the plot.
In practice, since the resolution of the display screen displaying the image may be different, in order to facilitate the display of the plot information and the sub-scene information under each display screen, a coordinate transformation may be introduced, for example, when the save button is clicked, the above window position information and the plot information are subjected to relative position conversion, for example, conversion into corresponding information under a resolution of 1920 × 1080 (common display screen resolution), and at the same time, the converted information is written into a custom file, such as a json file, and the suffix of the file is changed into a custom format. Due to the fact that the user-defined format cannot be acquired by others in advance, the plotting information and the sub-scene information can be further effectively protected in the transmission process and the reloading and reading process, and the plotting information and the sub-scene information are prevented from being easily known by others; moreover, the plotting information and the sub-scene information have practical significance only when being used together, if other people only obtain one of the information, for example, the plotting information, which may be, for example, circle information, the practical significance of the circle cannot be known because other people cannot really know what content the circle is on, and therefore, in the present invention, if only one of the plotting information and the sub-scene information is accidentally obtained and read by other people, the real leakage of the plotting cannot be caused. Further, the plot information and the sub-scene information may be independently stored in two files, and may be read when the information is read. Further, in the related art, for example, the QQ chat tool, when sharing plot information in chat, it is necessary to implement transmission of a picture with a plot itself, and thus, in addition to easy exposure of the plot, there are problems of bandwidth occupation on a network path between a sender and a receiver, or low transmission efficiency, which are related to transmission of the plot picture (especially when the plot information is complicated and the picture is super large). The plotting process is stored into the plotting information and the sub-scene information (or the scene information below), so that the plotting image can be prevented from being directly transmitted between the plotting sharing party and the receiving party, and the problem of congestion or bandwidth occupation on a network path between the plotting sharing party and the receiving party is also avoided.
In addition, a start plotting button for starting the editable mode may be set in advance. For example, before the plotting, the computer may set the region where the image is located to an editable mode to be an editable region in accordance with the operation of the start plotting button (also referred to as an editing button) by the client; upon entering the editable mode, a mouse event is captured and interpreted as performing a plotting operation on the editable area. The editable area may also be predefined to cover the area in which the window for displaying the image is located (as shown in fig. 2 b) or to cover the full screen or only an area as large as the window. In addition, it is also possible to first cause the window to be displayed in full screen by a full screen button or shortcut, after the start plotting button is operated, the computer enters a full screen editable mode, and the plotting operation thereafter is made available on the entire screen. The computer may also save the image containing the plotting information at a certain time as an overall image (i.e., a screenshot) as additional reference data according to the operation of a screenshot saving operation button by the client.
Further, in some other embodiments, the computer may also cause the window or associated area to automatically enter an editable mode upon recognizing that the customer is clicking the plot button.
In some cases, if the image is a dynamic image changing in real time in a video stream from a signal source, when plotting the image, a screen capture operation may be started first to provide a static screenshot for an operator to view for plotting (i.e. a background image, which is convenient for the operator to know where the operator is plotting). Plot information and sub-scene information may be saved at the end of the plot, or as the plot progresses, as previously described. In addition, as an additional operation, according to actual needs, at a certain time in the plotting process or before the plotting is finished or performed, a screen capture operation may be performed on the plotted interface, and the image containing the plotting information or the initial image may be saved as an overall image (i.e., a screen capture) to be used as an additional reference. Taking a camera monitoring scene as an example, if a certain specific part in a monitoring picture is desired to be monitored, a certain specific area in a monitoring area can be circled at a certain initial time through plotting operation to plot, corresponding plotting information and sub-scene information are stored, and when a file containing the plotting information and the sub-scene information is reloaded later, a user can very conveniently notice the circled area and perform important monitoring on the circled area, so that tracking monitoring on the specific area in the monitoring area is realized. In addition, after the screenshot with the plotting information is saved as an image, the image can be used as a comparison reference to observe the change of the same area from the beginning to the current state.
Fig. 3 schematically shows a computer screenshot acquired when a second embodiment of a plot processing method according to the present invention is implemented on a computer.
In this embodiment, the computer is connected to a plurality of signal sources, each of which may be arranged on one side of the screen in an identified manner, as shown in fig. 3, wherein the plurality of signal sources are arranged in sequence in an area of the display window near the left side in a manner of one frame image. In addition, a plurality of signal sources can be sequentially listed in the area close to the left of the display window in a manner of identification such as signal source name or IP address.
By predefining a command corresponding to the dragging operation, the identifier can be dragged and released at a certain position on a screen, so that the image of the signal source corresponding to the identifier is displayed on a window at the position; in addition, by defining the display position corresponding to each signal source in advance, a plurality of signal sources can be displayed on the window at the corresponding display position through clicking operation.
The computer may be responsive to a customer's plotting operation to sequentially plot each image drawn on each window, including drawing lines on the images, adding geometry diagrams, flow charts, annotating, adding text, coloring, and the like.
For the plotted image, the computer saves the corresponding plot information and scene information according to the saving operation of the client (for example, clicking a saving button). The scene information includes window signal information and window position information of all windows on which the image is drawn. The window signal information includes the network flow addresses of the images in all the windows, and according to the network flow addresses of the images, the computer can acquire the images corresponding to the network flow addresses again through the network. The plotting information and the scene information are adapted to be re-read to enable the acquisition and loading of the respective images (by network stream addresses in the window signal information of the scene information) and the loading of the plots on the respective images, i.e. to complete the plotting of the images.
In this embodiment, before the customer plots the images, the computer may put the regions where the respective images are located into the editable mode in advance according to the plotting action of the customer. Or, depending on the signal source, for example, especially when the signal source is a dynamic real-time changing signal source, a screenshot can be initiated to form a static screenshot for the operator to view for plotting. After plotting is finished, besides the aforementioned stored plotting information and scene information, the final picture with the plotting information can be subjected to screen capture in response to the operation of the client to obtain the screenshot.
The present embodiment is different from the foregoing embodiments mainly in that, in the present embodiment, when plotting images, plotting of images corresponding to a plurality of signal sources is involved, and window signal information and window position information corresponding to all images, and plot information are saved. As previously described. It will be apparent to those skilled in the art after reading this application that many of the foregoing descriptions of the first embodiment described with respect to fig. 1 and 2, and other embodiments mentioned herein, apply mutatis mutandis to the embodiment of fig. 3, for example, the network stream addresses of the images comprise respective rtsp stream addresses; the plotting information comprises line information, geometric shape information, flow chart information, marking information, character information and color information; the window signal information comprises a signal source name, a signal source resolution and a signal source IP address; storing the plotting information and the scene information in a custom format in one file, or independently storing the plotting information and the scene information in two or more files. In addition, a start plotting button for starting the editable mode may be set in advance. For example, before the plotting, the computer may cause the region in which the image is located to enter an editable mode to become an editable region in accordance with the operation of the start plotting button by the client; upon entering the editable mode, a mouse event is captured and interpreted as performing a plotting operation on the editable area. The editable area may also be predefined to cover all windows (as shown in fig. 3) for displaying the image or the area where one of the windows is located or cover the full screen, or the position and size of one or more of the windows may be determined according to actual conditions, and then the area where the one or more windows are located is set as the editable area. For the sake of brevity, further description will not be provided herein.
The present application further provides a method of shared image plotting, comprising: and the image plotting sender transmits the plotting information and the sub-scene information saved according to the plotting processing method to an image plotting sharing party, and the image plotting sharing party reads the plotting information and the sub-scene information and performs drawing of the image and loading of the plotting according to the plotting information and the sub-scene information.
According to yet another embodiment of the method of shared image plotting of the present application, the method comprises: and the image plotting sender transmits the plot information saved according to the plotting processing method and the scene information to an image plotting sharing party, and the image plotting sharing party reads the plotting information and the scene information and carries out drawing of each image and loading of plotting according to the plotting information and the scene information.
According to some embodiments of the present invention, in the aforementioned two method embodiments of shared image plotting, the transmitting may be implemented by way of a network, and the transmitting may be implemented by way of various dump storage media. The network mode includes downloading the plot information and/or sub-scene information (or scene information) through a network. The dump storage medium may be, for example, a flash memory, an optical disc, a magnetic disc, or a combination of two or more of these; a dump storage media may also include removable or non-removable media; the dump storage medium may be internal or external to the device; the storage medium may be a non-volatile solid-state memory, a read-only memory, an erasable prom (eprom), or a combination of two or more of these.

Similarly, the plotting information and the scene information can be stored in a file in a custom format, or stored in two or more files, and the information is read and loaded in a corresponding manner when being read and loaded.
According to some embodiments of the present invention, the plotting reproduction method may further include, after the plotting is loaded, performing a screen capture operation on the area where the image is located to form a static screenshot for an operator to view for plotting, and although the plotting information and the image information are finally stored instead of a screenshot information, the screenshot facilitates a still image to be referred to when plotting, and particularly, when the image loaded according to the network stream address changes in real time, a still image is obtained to plot, which has a practical reference meaning. According to some embodiments of the present invention, after the plotting is loaded, the region where the image is located may enter an editable mode, so that the image may be further plotted.
According to some embodiments of the present invention, the plot reproduction method may further include, after the plot is loaded, removing the plot loaded on the image by hiding or closing a plot layer corresponding to the plot, for an operator to restart the plot on an image without a plot mark.
