Background
An LED large screen (composed of a plurality of displays) in a public area is often deployed in an area with larger pedestrian volume, and displayed contents are generally important text information and relatively fixed video promos, advertisements and the like. When the information on the screen up to the large screen contains sensitive or illegal information, the social impact caused by the information is relatively large. How to monitor information of large screens in real time becomes a difficult problem in city renovation, and the large screens are often deployed outdoors/on roads and the like, so that when sensitive information or image quality problems occur, it is difficult to control and adjust the image quality in time.
At present, the following two methods are often adopted for processing: (1) The method mainly comprises the steps that physical isolation is achieved, equipment on a large screen can be operated by a person with a specific authority, meanwhile, related management departments carry out spot check, and retroactive processing is carried out afterwards. (2) The large screen is aligned through the camera, screen content is collected in real time and uploaded to the intelligent server for analysis, and when sensitive information or abnormity occurs, the management platform timely informs the large screen controller to process the information through the network.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It should be further noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings, not all of them.
Example one
Fig. 1 is a flowchart of a screen information monitoring method according to an embodiment of the present invention, where the embodiment is applicable to a situation where a network is abnormal or a video line from a screen controller to a screen is broken, and the method may be executed by a screen information monitoring apparatus, and the apparatus may be configured on a network camera.
As shown in fig. 1, the screen information monitoring method provided in the embodiment of the present invention may include:
s101, analyzing information content displayed on a screen acquired in real time, and matching an analysis result with standard content stored in advance.
In the embodiment of the invention, the screen monitoring and intelligent analysis preprocessing of the network camera are completed firstly. For example, the relationship between the screen controller of the screen and the network camera is bound in advance and registered to a video monitoring platform to realize the correspondence between the screen and the network camera, wherein the video monitoring platform is used for realizing the service control and management of the monitoring system, and is mainly responsible for the signaling interaction and scheduling of the service, and managing the equipment information and the user information of the whole system. And further completing installation and deployment of the network camera and the screen. The infrared light supplement module on the network camera is simultaneously provided with 850nm and 940nm infrared light supplement lamp beads (the 850nm emission power is stronger than 940nm emission power, the remote control distance is relatively slightly far, and about 1-12 infrared light supplement lamp beads are arranged on a common infrared camera). And when the infrared controller is installed and deployed, the picture of the camera can be ensured to be just monitored to the complete picture of the screen, and the infrared controller can normally control the screen. It should be noted that, the infrared light supplement lamp bead with remote control capability is arranged to have no influence on the image effect of the infrared light supplement.
Further, the network camera is accessed to the video surveillance platform based on a communication protocol, and illustratively, the network camera is accessed to the video surveillance platform through a national standard protocol or an onvif protocol. Furthermore, a national standard protocol or an onvif protocol is extended, so that when the network camera is accessed to the video supervision platform, the infrared remote control capability of the network camera is reported to the video supervision platform. Illustratively, the infrared remote control capability reported by the onvif protocol includes: the infrared supplementary lighting lamp bead of the network camera has remote control capability, and 10 lamp beads are provided in total, wherein the 1 st to 5 th wavelength is 940nm and supports the NEC control protocol, and the 6 th to 10 th wavelength is 850nm and supports the NEC control protocol.
Further, after the network camera is accessed to the video monitoring platform, the video monitoring platform issues the information to be displayed, which is approved by the verification, as standard content to the network camera for storage. As an optional implementation manner, the video monitoring platform analyzes and extracts the structural feature information from the information to be displayed, which passes the examination, and issues the structural feature information as standard content to the network camera for storage. Specifically, the video monitoring platform comprises an intelligent analysis server and a video management server, the intelligent analysis server analyzes received information to be displayed which is audited by a monitoring department and extracts structural feature information (such as video feature vectors or characters and the like), the intelligent analysis server transmits the extracted structural feature information to the video management server, and the video management server issues the feature information to the network camera.
On the basis, the network camera analyzes the information content of the screen display acquired in real time, for example, analyzes the video played by the screen or the displayed characters, correspondingly extracts the characteristic information as an analysis result, and matches the analysis result with the pre-stored structural characteristic information to determine whether abnormal content (for example, illegal content) exists in the information displayed on the screen.
S102, judging whether abnormal content exists in the currently displayed information or not according to the matching result, and if so, executing S103.
Illustratively, if the analysis result has characteristic information which cannot be matched with the pre-stored structural characteristic information, the abnormal content is determined to exist in the content displayed on the screen. In an implementation manner, a threshold of matching degree may be preset, and if it is determined that the matching degree of the analysis result and the pre-stored structural feature information is lower than the threshold of matching degree, it is determined that abnormal content exists in the content displayed on the screen.
S103, controlling the infrared light supplementing lamp beads to emit infrared remote control signals to an infrared receiving controller of the screen so as to control abnormal contents displayed by the screen.
In this embodiment, after the abnormal content on the screen is detected, any one infrared supplementary lighting lamp bead can be controlled to transmit an infrared remote control signal to the infrared receiving controller of the screen, so as to control the abnormal content displayed on the screen.
In order to improve the accuracy of control, preferably, a target infrared supplementary lighting lamp bead is selected based on a screening strategy, and the target infrared supplementary lighting lamp bead is controlled to transmit an infrared remote control signal to an infrared receiving controller of the screen so as to control the abnormal content displayed by the screen. The screening strategy at least comprises screening based on a control protocol supported by the infrared supplementary lighting lamp beads and the screen or screening based on the distance between the network camera and the screen. For example, the network camera is far away from the screen, and one of the lamp beads with the wavelength of 850nm can be selected as a target infrared supplementary lighting lamp bead. And then the target infrared light supplementing lamp bead is controlled to transmit an infrared remote control signal to an infrared receiving controller of the screen so as to control abnormal contents displayed by the screen. Illustratively, the abnormal content may be handled by closing the screen or controlling the screen to play the preset content.
Furthermore, the screen is a spliced screen formed by a plurality of displays according to a set splicing mode, wherein each display is connected in series to an infrared receiving controller of the screen through a serial port. It should be noted that, after the binding relationship between the screen and the webcam is completed, the video surveillance platform informs the webcam of the splicing mode of the screen, the IP address information, and the like, where the splicing mode is illustratively 3 × 3 or 4 × 4.
Therefore, when the abnormal content exists in the information currently displayed on the screen, analyzing the position of the abnormal content in the screen, and further determining the target display where the abnormal content is located by combining the position of the abnormal content in the screen and the splicing mode of the screen; and selecting a target infrared supplementary lighting lamp bead based on a screening strategy, and controlling the target infrared supplementary lighting lamp bead to transmit an infrared remote control signal to an infrared receiving controller of a screen so as to control abnormal contents displayed by the target display, for example, turning off the target display or playing preset contents.
Furthermore, the network camera can monitor whether abnormal content exists in the information displayed on the screen, and can detect and analyze the quality of the picture image displayed on the screen. And when detecting that the image quality of the picture displayed by any display forming the screen has a problem, controlling the infrared light supplementing lamp bead to emit an infrared remote control signal to an infrared receiving controller of the screen so as to adjust the display, for example, increasing the brightness and the aspect ratio of the display. It should be noted that the image quality of the display screen is directly adjusted by the network camera, so that the image quality is not limited by the network state, and the image quality of the screen is prevented from being adjusted in the field by manpower.
Furthermore, under the condition of good network state, the image quality of the screen can be adjusted through remote control. Specifically, a user opens a real-time video of the camera at a far end, a soft remote control panel is arranged on a far-end computer, and when a remote control command is manually issued, the video supervision platform can carry a control code in a message according to an access protocol of the network camera and send the message to the network camera for analysis and processing. Therefore, when a user determines that the quality of certain images in the screen needs to be adjusted, the network camera is controlled on the remote computer to remotely control the display screen to adjust through the infrared light supplementing lamp beads. It should be noted that when the selected infrared light supplement lamp bead does not have an effect on controlling and adjusting the large screen, whether the infrared light supplement lamp bead of the network camera is damaged or not can be remotely judged.
In this embodiment, when it is determined that there is an abnormal content in the currently displayed information, the infrared light supplement lamp bead is controlled to transmit an infrared remote control signal to the infrared receiving controller of the screen, so as to control the abnormal content displayed on the screen. Therefore, the screen content is safely supervised by the network camera, the manual checking input is reduced, and the screen can be controlled by the network camera even if the network is abnormal or a video line from the screen controller to the screen is damaged. Meanwhile, the image quality of the screen can be adjusted through a network camera or a far end, and manual on-site adjustment is avoided.
Example two
Fig. 2 is a flowchart illustrating a screen information monitoring method according to a second embodiment of the present invention. The present embodiment is optimized based on the above embodiment, and as shown in fig. 2, the screen information monitoring method provided in the embodiment of the present invention may include:
s201, analyzing the information content displayed on the screen acquired in real time, and matching the analysis result with the pre-stored standard content.
The standard content is information to be displayed which is sent to the network camera by the video monitoring platform and passes the examination and the verification. As an optional implementation manner, structured feature information analyzed and extracted by the video supervision platform from the information to be shown passing the audit can be used as standard content.
S202, judging whether abnormal content exists in the currently displayed information according to the matching result, and if so, executing S203.
S203, sending a message that abnormal content exists on a screen to the screen controller, so that the screen controller controls the screen to process the abnormal content.
Because the network camera and the screen controller have a binding relationship, the network camera can also realize the purpose of sending a message that abnormal content exists on a screen to the screen controller, so that the screen controller controls the screen connected with the screen controller through a video line to process the abnormal content, for example, the screen is controlled to be closed or preset content is played.
And S204, judging whether the abnormal content is successfully processed, and if not, executing S205.
When the screen controller is informed to perform exception processing, and the picture displayed on the screen still has exception content, it indicates that the screen controller may have been hacked or the video line is damaged, and may not make a correct response. Thus, by executing S205, control is directly performed by the network camera.
S205, controlling the infrared light supplementing lamp bead to emit an infrared remote control signal to an infrared receiving controller of the screen so as to control abnormal contents displayed by the screen.
Further, for the event that the abnormal content appears on the screen, the network camera feeds back to the video monitoring platform, and the video monitoring platform generates a warning message and pushes the warning message to the terminal of the user, for example, the warning message is notified through an app message or a short message. In addition, if the screen is blocked or the network camera is off-line, the video monitoring platform informs maintenance personnel to process in time through short messages, mails and the like.
Further, in the embodiment of the present invention, in addition to monitoring the abnormal content, the screen may be controlled to enter the energy saving mode, for example, the screen is controlled to enter the energy saving mode according to the flow of people in the area where the screen is located or the time arrangement. The judgment is carried out according to the flow of people, and can be carried out according to the following steps:
reporting the pedestrian flow information of the area where the screen is located to the video monitoring platform, so that when the video monitoring platform determines that the pedestrian flow is smaller than a threshold value, an energy-saving instruction is issued;
and responding to an energy-saving instruction issued by the video monitoring platform, and controlling the infrared light supplementing lamp beads to emit infrared remote control signals to an infrared receiving controller of the screen so as to control the screen to enter an energy-saving mode. The energy-saving mode is carried out by directly controlling the screen through the network camera without the limitation of a network state and a video line between the screen controller and the screen.
As another implementable manner, under the condition that the network state is good or the video cable is normal, the video monitoring platform issues an energy saving instruction to the screen controller, so that the screen controller controls the screen to perform an energy saving mode. And the screen controller can also judge whether to control the screen to enter the energy-saving mode according to the current time.
In this embodiment, the network camera may notify the screen controller to implement control over the abnormal content of the screen, or may directly control the screen to process the abnormal content, so as to ensure monitoring of the content displayed on the screen. Moreover, the energy can be saved by controlling the screen through the network camera.
