[0029] Figure 1 The block diagram of the monitoring display screen switching system for an offshore photovoltaic construction site according to an exemplary embodiment of the present disclosure is schematically shown. Figure 1 The monitoring display screen switching system 1 for offshore photovoltaic construction sites of the embodiment of the present disclosure may include multiple cameras 110, a data processing device 12 and a display device 13. The multiple cameras 110 may be respectively connected to the data processing device 12 and the display device 13 in communication to transmit the collected on-site video frame images. The data processing device 12 may be connected to the display device 13 in communication to realize the display control of the display device 13 by the data processing device 12.

[0030] Multiple cameras 110 can be configured at different locations of the offshore photovoltaic construction site. Specifically, these cameras can be distributed in various areas related to the offshore photovoltaic site, such as the offshore construction area, the ground construction area, the project command and management area, etc. The present disclosure does not limit the number of cameras installed on site.

[0031] The data processing device 12 can be used to obtain the video frame images collected by each camera, perform event analysis on the video frame images, determine the event monitoring level corresponding to the video frame images collected by each camera based on the result of the event analysis, determine the video frame images collected by one or more target cameras as the target display content according to the event monitoring level corresponding to the video frame images collected by each camera, determine the event monitoring level distribution of the video frame images included in the target display content, determine the target display mode according to the event monitoring level distribution, and obtain the identification of the target camera. In the target display mode, at least the target display content is displayed.

[0032] The display device 13 can be used to obtain the target display mode and the target camera identifier sent by the data processing device 12, obtain the video frame image captured by the target camera in real time according to the target camera identifier, switch the current display mode to the target display mode, and display the video frame image captured by the target camera in real time in the interface style of the target display mode. The difference in interface style of different display modes includes one or more of different arrangement of the screens corresponding to the video frame images, different numbers of screens, and different display sizes of the screens.

[0033] refer to Figure 1 The monitoring display screen switching system 1 may also include a wind sensor 14, which is used to obtain offshore wind data. In this case, for the offshore camera, the process of the data processing device 12 determining the event monitoring level may also include: obtaining the offshore wind data collected by the wind sensor 14, and performing coefficient conversion on the offshore wind data to obtain a target coefficient; obtaining the video frame image collected by the offshore camera and performing event analysis to obtain an event analysis score; and determining the event monitoring level corresponding to the video frame image collected by the offshore camera using the target coefficient and the event analysis score.

[0034] The specific processing process of the data processing device 12 is described below.

[0035] For the event analysis process based on video frame images, first, a historical image collected by a camera corresponding to the video frame image and pre-calibrated can be obtained, wherein the event monitoring level of the historical image is any one of all event monitoring levels.

[0036] In an exemplary embodiment of the present disclosure, the event monitoring level can be divided into A, B, C, D, etc., or can be divided into level 1, level 2, level 3, etc., and the present disclosure does not limit the number of level divisions for event monitoring levels. In some embodiments, the earlier the number, the higher the need and urgency for event monitoring. For example, the monitoring urgency of level A is higher than the monitoring urgency of level B, and the monitoring urgency of level 1 is higher than the monitoring urgency of level 2. In other embodiments, the later the number, the higher the need and urgency for event monitoring. For example, the monitoring urgency of level B is lower than the monitoring urgency of level C, and the monitoring urgency of level 3 is higher than the monitoring urgency of level 2. These can be adjusted according to needs and habits, and the present disclosure does not limit this.

[0037] Taking the event monitoring levels as A, B, C, and D as an example, the event monitoring level of the above historical images can be any one of A, B, C, and D, and the present disclosure does not limit the selection of historical images.

[0038] Next, the video frame image can be compared with the historical image to determine the image content difference. The image content difference can include differences caused by human factors or differences caused by natural factors. Differences caused by human factors include, for example, vehicles, personnel, ships, etc. Differences caused by natural factors include, for example, waves, heavy rain, etc.

[0039] Specifically, the image content difference between the video frame image and the historical image can be deducted from the video frame image as the image foreground to obtain a separate image content difference. It can be understood that the pixel value of the image background corresponding to the image content difference can be unified to 0 or 255. In order to use the separate image content difference for subsequent analysis.

[0040] Then, the event analysis score can be determined according to the image content difference, and the event analysis score can be used as the result of event analysis on the video frame image.

[0041] Specifically, the scoring process can rely on the existing mature convolutional neural network to achieve classification scoring of the model by constructing sample pairs to train the convolutional neural network in advance. In other words, the image content difference can be input into the convolutional neural network, and the convolutional neural network outputs the event analysis score. The present disclosure does not limit the specific structure and training process of the convolutional neural network.

[0042] According to some embodiments of the present disclosure, the event monitoring level corresponding to the video frame image captured by the camera can be directly determined based on the result of the event analysis. Specifically, the corresponding event monitoring level can be determined according to the event analysis score. Taking the event monitoring levels as A, B, C, and D as an example, event analysis scores greater than or equal to 75 are classified as level A, event analysis scores between 50 and 75 are classified as level B, event analysis scores between 25 and 50 are classified as level C, and event analysis scores below 25 are classified as level D. It should be noted that this is only an exemplary description and the present disclosure does not limit this.

[0043] For the scheme of determining the event monitoring level in combination with offshore wind data from a wind sensor, it should be understood that the greater the wind force, the greater the target coefficient, and the greater the impact on the event monitoring level. In other words, the wind force value of the offshore wind data is positively correlated with the target coefficient, and the representation of the positive correlation can be simulated through multiple tests, and the present disclosure does not limit this.

[0044] In other embodiments of the present disclosure, the positive correlation relationship can be artificially defined in advance to construct a mapping relationship between wind force value and target coefficient. Thus, when the wind force value of offshore wind force data is known, the target coefficient corresponding to the wind force value can be determined by means of the mapping relationship.

[0045] In addition, the target coefficient can be multiplied by the event analysis score, and then the product result can be converted into the event monitoring level. Taking the event monitoring level as A, B, C, and D as an example, the multiplied value is greater than or equal to 75 and is classified as level A, the value between 50 and 75 is classified as level B, the value between 25 and 50 is classified as level C, and the value below 25 is classified as level D. It should be noted that this is only an exemplary description, and the present disclosure does not limit this.

[0046] Regarding the process of determining the target display content, first, the event monitoring level corresponding to the video frame image captured by each camera can be compared with the level threshold. Next, the camera whose event monitoring level is greater than or equal to the level threshold can be determined as the target camera, and the video frame image captured by the target camera is used as the target display content. Among them, the level threshold can be set to level B, level 2, etc. It can be understood that the level threshold is related to the level division and the probability of occurrence of the event to be monitored on site, and the present disclosure does not limit this.

[0047] As described above, the embodiment of the present disclosure also includes a process of determining a target display mode. First, the display mode mentioned in the present disclosure is described.

[0048] In an exemplary embodiment of the present disclosure, the differences in interface styles of different display modes include one or more of different arrangement modes of the screens corresponding to the video frame images, different numbers of screens, and different display sizes of the screens. Among them, the arrangement mode of the screens refers to the arrangement order of the screens on the entire interface, the number of screens refers to the total number of screens presented on the entire interface, and the display size of the screens refers to the size of each screen presented on the interface.

[0049] Figure 2 A schematic diagram showing a display mode of an embodiment of the present disclosure is shown. Figure 2 In this display mode, the display size of the corresponding images of the cameras is the same. This display mode can usually be configured as the default display mode or when the current event monitoring level is not high.

[0050] Figure 3 FIG. 2 is a schematic diagram showing another display mode of an embodiment of the present disclosure. Figure 3 In this display mode, the display size of the camera corresponding to the screen is also the same, but compared to Figure 2 , the display size of the corresponding camera screen is larger.

[0051] When this display mode is applied as the target display mode, the video frame images of the cameras involved can be interpolated to improve the resolution of the picture, thereby improving the viewing experience of the viewer.

[0052] Figure 4 A schematic diagram showing another display mode of an embodiment of the present disclosure is shown. Figure 4 ,In this display mode, the display sizes of the corresponding images of the cameras are not exactly the same, and the ,visual effects presented include that the image of camera 1 is enlarged, proving that the image of camera 1 is the ,construction event image that the computer analyzes itself and should receive special ,attention.

[0053] Similarly, when this display mode is applied as the target display mode, the enlarged picture may be interpolated to improve the resolution of the picture, thereby improving the viewing experience.

[0054] It should be noted that Figures 2 to 4 This is only an exemplary description of the display mode of the present disclosure. Through the above description, other screen configuration methods can also be associated, and the present disclosure does not limit this.

[0055] Regarding the process of determining the target display mode, it should be noted that the event monitoring level distribution mentioned in the present disclosure may include the event monitoring level involved in the target display content and the number of video frame images at each event monitoring level. For example, the event monitoring level involved in the target display content includes level A and level B, the number of video frame images corresponding to level A is 1, and the number of video frame images corresponding to level B is 11.

[0056] According to some embodiments of the present disclosure, a mapping relationship between event monitoring levels and the number of video frame images at each event monitoring level and display mode can be pre-constructed, and the target display mode can be determined using the mapping relationship. Still using the above example, the number of video frame images corresponding to level A is 1, and the number of video frame images corresponding to level B is 11. In this case, the target display mode can be, for example, Figure 4 in the form of.

[0057] For example, the target display content includes a first video frame image captured by a first camera and a second video frame image captured by a second camera. If the event monitoring level corresponding to the first video frame image is higher than the event monitoring level corresponding to the second video frame image, then in the target display mode, the display size of the screen corresponding to the first video frame image is larger than the display size of the screen corresponding to the second video frame image.

[0058] In addition, the present disclosure also provides a solution for locking the interface of part or all of the images after switching the display screen.

[0059] Specifically, when the video frame images captured by the target camera in real time are displayed in the interface style of the target display mode, in response to the locking operation on one or more video frame images on the interface, one or more video frame images are controlled to be locked. The locking means that the interface style of the corresponding screen of the locked video frame image remains unchanged. The present disclosure does not limit the locking operation, such as the mouse click operation of the operator, the text input operation, etc.

[0060] In addition, for the process of switching the monitoring display screen executed by the above system, in order to save resources, the data processing device 12 can execute the above processing process every predetermined time, and the predetermined time can be, for example, 5 minutes, 10 minutes, etc. This aspect is related to the current monitoring needs. For example, when there is no construction on site, the predetermined time can be set to a larger value. Conversely, if construction is in progress, the predetermined time can be set to a smaller value, at least less than the situation when there is no construction on site.

[0061] The following describes the method for switching monitoring display screens for an offshore photovoltaic construction site executed by the data processing device 12 according to an embodiment of the present disclosure.

[0062] Figure 5The flowchart of the monitoring display screen switching method for an offshore photovoltaic construction site according to an exemplary embodiment of the present disclosure is schematically shown. Figure 5 The monitoring display screen switching method may include the following steps:

[0063] S502. Obtain video frame images collected by multiple cameras, where each camera is configured at a different location on the offshore photovoltaic construction site.

[0064] S504. Perform event analysis on the video frame images, and determine the event monitoring level corresponding to the video frame images collected by each camera based on the result of the event analysis.

[0065] S506. Determine the video frame images captured by one or more target cameras as target display content according to the event monitoring level corresponding to the video frame images captured by each camera.

[0066] S508. Determine the event monitoring level distribution of the video frame images included in the target display content, and determine the target display mode according to the event monitoring level distribution.

[0067] Specifically, in the target display mode, at least the target display content is displayed. In addition, the differences in interface styles of different display modes include one or more of different arrangements of video frame images corresponding to screens, different numbers of screens, and different display sizes of screens.

[0068] S510. Obtain the ID of the target camera.

[0069] S512. Send the target display mode and the identifier of the target camera to the display device.

[0070] Specifically, the target camera identifier instructs the display device to obtain the video frame image captured by the target camera in real time, and the target display mode instructs the display device to switch the current display mode to the target display mode, and display the video frame image captured by the target camera in real time in the interface style of the target display mode.

[0071] Since the detailed process of the monitoring display screen switching method for an offshore photovoltaic construction site in the embodiment of the present disclosure is the same as that in the above-mentioned system implementation, it will not be repeated here.

[0072] It should be noted that although the steps of the method in the present disclosure are described in a specific order in the drawings, this does not require or imply that the steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired results. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step, and / or one step may be decomposed into multiple steps, etc.

[0076] Since the functional modules of the monitoring display screen switching device for an offshore photovoltaic construction site in the embodiment of the present disclosure are the same as those in the above-mentioned system implementation, they will not be described in detail here.
