[0002] With the acceleration of urbanization and the increase in social security needs, video surveillance systems have been widely used in urban security, traffic management, public safety and other fields. For example, high-point video surveillance systems, by installing high-resolution cameras at high altitudes, can cover a wider monitoring range, reduce monitoring blind spots, and accurately detect and locate events through intelligent analysis technology. However, relying solely on video surveillance systems for event detection and location still has problems such as untimely information transmission and inflexible emergency response. Therefore, when an abnormal event occurs, it is usually necessary to use broadcasting equipment for broadcasting. Currently, related technologies usually manually pre-set fixed broadcasting equipment for broadcasting, or manually select broadcasting equipment based on experience when an abnormal event occurs, resulting in low accuracy in reporting abnormal events.

Figure 1 More or fewer components than shown, or with Figure 1 Different configurations shown.

[0036] It should be noted that the one or more processors 102 and / or other data processing circuits described above may generally be referred to herein as "data processing circuitry." This data processing circuitry may be embodied in whole or in part as software, hardware, firmware, or any other combination thereof.

As discussed in the embodiments of this application, this data processing circuitry functions as a processor control (e.g., selecting a variable resistor terminal path connected to an interface).

[0037] The memory 104 can be used to store software programs and modules of application software, such as the program instructions / data storage device corresponding to the broadcast device control method in the embodiments of the present application.

[0040] Under the above operating environment, this application provides Figure 2 The control method of the broadcasting device shown. Figure 2 The process of the control method of the broadcasting device provided in the embodiment of the present application is as follows Figure 1 .

[0041] Step S201: Obtain video data of a target area and detect whether there is any abnormal event in the video data.

[0042] Optionally, electronic devices, application systems, servers and other devices may be used as the execution subject of this application. In this embodiment, the target processing system is used as the execution subject to execute the above-mentioned control method of the broadcasting device.

[0043] Optionally, the target area can be imaged through a target image acquisition device to obtain video data of the target area. The target area refers to a specific geographical space that needs to be monitored, such as a city square, park, forest, farm, etc. The target image acquisition device can be a camera, for example, a high-point camera. A high-point camera is a monitoring device installed at a high position, usually used to cover a large area or monitor specific high-risk areas. This system takes advantage of the field of view of high-position cameras to provide wide-angle, panoramic or long-distance monitoring views, and is suitable for various scenarios such as urban management, traffic monitoring, and border security. The visual range of a high-point camera is usually a fan-shaped or circular area. And its field of view meets the following requirements:

[0044] Circular viewing area:

[0045]

[0046] Fan-shaped viewing area:

[0047]

[0048] in, represents the horizontal coordinate of the camera, represents the vertical coordinate of the camera, The camera's orientation angle is represented by the camera's azimuth, and R represents the radius of the camera's field of view. The target processing system can map the camera's location and field of view for user reference. High-point cameras improve video surveillance coverage, avoiding blind spots when identifying and locating abnormal events and providing precise location information.

[0049] Optionally, video image data can be captured and transmitted in real time to a target processing system via a high-point camera device.

[0050] Optionally, abnormal events include but are not limited to sudden or unexpected events that can be identified in video data, such as human intrusion, traffic accidents, natural disasters, and damage to public facilities.

[0051] Step S202: When an abnormal event exists in the video data, the geographical coordinates of the location where the abnormal event occurs are determined.

[0052] Optionally, the target processing system may determine the pixel coordinates of the location where the abnormal event occurred in the video frame of the video data, and thereby calculate the actual geographic coordinates of the location where the abnormal event occurred in combination with the installation position and angle of the target image acquisition device.

[0053] Optionally, when no abnormal event exists in the video data, the video data of the target area continues to be acquired.

[0054] Step S203, according to the geographic coordinates, determine the target broadcasting device from multiple preset broadcasting devices, and broadcast the warning information corresponding to the abnormal event through the target broadcasting device, wherein the target broadcasting device refers to the broadcasting device whose sound propagation range covers the location where the abnormal event occurs.

[0055] Optionally, the multiple pre-defined broadcasting devices may be broadcasting devices located within or near the target area that can be used for emergency information broadcasting. Information such as their location, sound propagation range (also known as sound coverage), and sound pressure level information is pre-recorded in the system database. Optionally, the broadcasting devices may be cloud broadcasting devices.

[0056] Optionally, after determining the geographic coordinates of the location where the abnormal event occurred, the target processing system can calculate the distance between the abnormal event and the broadcasting device based on the geographic coordinates of the broadcasting device and the geographic coordinates of the location where the abnormal event occurred, and thereby determine the target broadcasting device based on the distance and the sound propagation range of the broadcasting device. The target broadcasting device can be understood as the broadcasting device that supports the transmission of the warning information to the location where the abnormal event occurred.

[0057] Optionally, after the target broadcast device is determined, the warning information corresponding to the abnormal event is broadcasted through the target broadcast device. The target processing system can preset the correspondence between different abnormal events and warning information. The target processing system can determine the warning information corresponding to the abnormal event based on the event type of the abnormal event, and then broadcast the warning information. For example, if the abnormal event is the intrusion of a large animal, the warning message may be "A large animal has intruded, please leave quickly!"; if the abnormal event is the accumulation of a large amount of garbage, the warning message may be "There is garbage piled up, please clean it up as soon as possible!"

[0058] In an embodiment of the present application, by detecting whether there is an abnormal event in the identification data of the target area, it is convenient to accurately determine the location of the abnormal event. By determining the target broadcasting device from multiple broadcasting devices based on the geographical coordinates of the location of the abnormal event, and setting the target broadcasting device to be a broadcasting device whose sound propagation range covers the location of the abnormal event, it is achieved that the broadcasting device used to broadcast early warning information is dynamically determined according to the location of the abnormal event, thereby improving the accuracy of the broadcast of abnormal events, and avoiding the situation where when a fixed broadcasting device is selected for broadcasting, the content broadcast by the broadcasting device may be difficult to be transmitted to the location of the occurrence, thereby resulting in invalid broadcast of the abnormal event.

[0059] It can be seen that the solution provided by this application achieves the purpose of dynamically determining the broadcasting equipment used for broadcasting based on the location of the occurrence of the abnormal event, realizes the technical effect of improving the accuracy of reporting of abnormal events, and solves the problem of low accuracy of reporting of abnormal events in related technologies when broadcasting equipment is needed to broadcast abnormal events.

[0060] Optionally, in the control method of the broadcasting equipment provided in the embodiment of the present application, detecting whether there is an abnormal event in the video data includes: performing preprocessing operations on the video data to obtain target video data; using a target recognition model to mark the target objects in the video frames in the target video data to obtain multiple marked video frames; and detecting whether there is an abnormal event in the video data based on the multiple marked video frames.

[0061] Optionally, preprocessing is used to improve the quality of video data, making it more suitable for subsequent object recognition and event detection. Video data preprocessing can include denoising, enhancement (such as improving image contrast and clarity), and stabilization (making the video frame sequence smoother and reducing jitter), thereby obtaining the target video data.

[0062] After obtaining the target video data, the target video data can be divided into multiple video frames, and then the multiple video frames can be input into the target recognition model, and the different objects in the video frames can be automatically identified and classified by the target recognition model. For example, the target object in each video frame is identified and located, and the bounding box and object type are marked in the video frame to obtain multiple labeled video frames for subsequent analysis. The aforementioned target object can be a person, a vehicle, an animal, etc., and the target recognition model can be a neural network model, which can be trained based on sample video frames and the marked labels in the sample video frames. The marked labels can include bounding boxes and object categories. The multiple labeled video frames are arranged in chronological order, that is, the multiple labeled video frames are continuous video frames.

[0063] After obtaining multiple labeled video frames, we can combine preset abnormal behavior rules or anomaly detection models to detect abnormal events in the video data by comparing the behavioral changes of the target object in consecutive frames. Abnormal events include but are not limited to human intrusion, medium to large quadrupeds, foreign objects, traffic accidents, garbage dumping, and damage to public facilities.

[0064] It should be noted that by preprocessing the video data and performing anomaly detection based on the target recognition results of the preprocessed video data, the detection accuracy can be effectively improved.

[0065] Optionally, in the control method of the broadcasting equipment provided in the embodiment of the present application, detecting whether there is an abnormal event in the video data based on multiple marked video frames includes: inputting the multiple marked video frames into an anomaly detection model, performing anomaly detection based on the multiple marked video frames through the anomaly detection model, and obtaining an anomaly detection result, wherein the anomaly detection result is at least used to characterize whether there is an abnormal event in the video data.

[0066] Optionally, the anomaly detection model may be a neural network model. After obtaining the plurality of labeled video frames, the target processing system may input the plurality of labeled video frames into the anomaly detection model, whereupon the anomaly detection model outputs an anomaly detection result, wherein the anomaly detection result is used to at least indicate whether an abnormal event exists in the video data. If an abnormal event exists in the video data, the anomaly detection result may further include the event type of the abnormal event and a marked box of the abnormal event in the video frame, where the marked box is used to indicate the location where the abnormal event occurred.

[0067] Optionally, the anomaly detection model can be trained through a training sample set. A single training sample in the training sample set may include multiple labeled sample video frames sorted by time. The sample video frames in a single training sample belong to the same sample video data. The true label of the training sample represents whether there is an abnormal event in the sample video data, the event type of the abnormal event, and the marking box of the abnormal event in the video frame.

[0068] It's important to note that the anomaly detection model enables automated and intelligent identification of abnormal events in video data, reducing the burden of manual monitoring and improving detection accuracy and efficiency. By analyzing target behavior patterns in consecutive video frames, the anomaly detection model can more accurately determine which changes constitute abnormal events, thereby reducing false alarm rates and improving the accuracy of anomaly detection.

[0069] Optionally, in the control method of the broadcasting device provided in the embodiment of the present application, the target broadcasting device is determined from a plurality of preset broadcasting devices based on the geographic coordinates, including: for each broadcasting device, determining the sound propagation range of the broadcasting device in the target direction based on the target angle and the transmission power of the broadcasting device, wherein the target angle refers to the angle between the transmission direction of the broadcasting device and the target line, the target line refers to the line between the location where the abnormal event occurs and the broadcasting device, and the target direction refers to the direction of the location where the abnormal event occurs relative to the broadcasting device; determining the distance between the broadcasting device and the location where the abnormal event occurs based on the geographic coordinates and the location information of the broadcasting device; determining the broadcasting device whose sound propagation range is greater than the distance as a candidate broadcasting device; and determining the target broadcasting device based on the candidate broadcasting device.

[0070] Optionally, the target processing system may calculate the sound propagation range (i.e., sound coverage range D) of the broadcasting equipment using the following formula:

[0071]

[0072] in, Indicates the transmission power of the broadcast equipment. represents the directional efficiency factor, Indicates the angle between the transmission direction of the broadcasting equipment and the target line. The target line refers to the line between the location where the abnormal event occurred and the broadcasting equipment. Indicates the air density (kg / m3), usually 1.21 kg / m3. Indicates the speed of sound (m / s), generally taken as 343 m / s (in 20°C air). represents the basic attenuation coefficient, represents the wind speed influence coefficient, V represents the wind speed, represents the humidity influence coefficient, Indicates humidity.

[0073] Optionally, the location information of the broadcasting device includes at least the geographic coordinates of the broadcasting device and may also include the installation height of the broadcasting device. The target processing system may determine the distance between the broadcasting device and the location of the abnormal event based on the geographic coordinates of the location of the abnormal event and the location information of the broadcasting device. For example, the distance value may be calculated based on the geographic coordinates of the broadcasting device and the geographic coordinates of the location of the abnormal event. For another example, the distance value may be calculated based on the geographic coordinates and installation height of the broadcasting device and the geographic coordinates of the location of the abnormal event.

[0074] After calculating the distance value, the target processing system may compare the distance value with the aforementioned sound propagation range D, thereby determining a broadcasting device whose sound propagation range D is greater than the distance value as a candidate broadcasting device.

[0075] Optionally, after determining the candidate broadcast devices, the target broadcast device can be determined based on the candidate broadcast devices. For example, all broadcast devices can be determined as target broadcast devices. For another example, the candidate broadcast device closest to the location where the abnormal event occurred can be determined as the target broadcast device. For another example, the target broadcast device can be determined from the candidate broadcast devices based on user instructions.

[0076] It should be noted that by calculating the sound propagation range of each broadcasting device and the distance from the event location, the system can intelligently select the broadcasting device that is most suitable for broadcasting. This not only ensures the effective transmission of early warning information, but also avoids broadcasting to non-essential areas, saving resources and reducing interference with the public.

[0077] Optionally, in the control method of the broadcasting device provided in the embodiment of the present application, the target broadcasting device is determined based on the candidate broadcasting devices, including: sending the device information of the candidate broadcasting device to the target user; receiving the device selection instruction feedback from the target user, and determining the target broadcasting device from the candidate broadcasting devices based on the device selection instruction.

[0078] Optionally, the device information includes at least a device identification of the candidate broadcast device, and may also include a model, power, coverage, current location, etc. of the candidate broadcast device.

[0079] Optionally, the target user may be a device administrator. The target processing system may send the device information of the candidate broadcast devices to the target user via SMS, email, application notification, or other means. After receiving the device information, the target user may select a device based on actual needs and provide a device selection instruction to the target processing system. The device selection instruction may include the device identifier of the candidate broadcast device selected by the target user. The target processing system may then determine the candidate broadcast device to which the device identifier in the device selection instruction belongs as the target broadcast device.

[0080] It should be noted that by allowing target users to participate in selecting broadcast devices, the flexibility of determining target broadcast devices is improved.

[0081] Optionally, in the control method of the broadcasting device provided in the embodiment of the present application, when there are multiple target broadcasting devices, before broadcasting the warning information corresponding to the abnormal event through the target broadcasting device, the method also includes: determining the propagation time required for the sound waves of each target broadcasting device to reach the occurrence location based on the distance between each target broadcasting device and the occurrence location of the abnormal event; and delaying the broadcast time point of at least one target broadcasting device based on the propagation time corresponding to each target broadcasting device, so that the sound waves of each target broadcasting device have the same phase when they arrive at the occurrence location.

[0082] Considering the scenario where multiple broadcast devices simultaneously play sound for a superimposed effect, to prevent the sounds transmitted by multiple broadcast devices from negatively impacting each other, it is necessary to ensure that the sound waves from each target broadcast device arrive at the same phase when they arrive at the source. This phase synchronization means that the sound waves' waveforms are synchronized upon arrival at the destination. Therefore, the target processing system can delay the start of each target broadcast device's broadcast to achieve this effect.

[0083] Optionally, for each target broadcasting device, the target processing system may calculate the ratio of the distance between the target broadcasting device and the location where the abnormal event occurs to the speed of sound, thereby obtaining the propagation time required for the sound waves of the target broadcasting device to reach the location where the abnormal event occurs.

[0084] Optionally, in order to ensure that the sound reaches the location where the abnormal event occurs at the same time, the target processing system can perform delay processing on broadcasting equipment with relatively short expected sound wave propagation time. If the warning information will be broadcast repeatedly, the target processing system can also perform delay processing on broadcasting equipment with relatively long expected sound wave propagation time, so that the warning information sent by the broadcasting equipment with longer propagation time for the first time and the warning information sent by the broadcasting equipment with shorter propagation time for the second time (or Nth time, etc., N is greater than 2) arrive at the location where the abnormal event occurs at the same time.

[0085] For example, the target processing system can first determine the longest propagation time corresponding to multiple target broadcasting devices, and then for each target broadcasting device, determine the difference between the propagation time of the target broadcasting device and the longest propagation time as the delay time corresponding to the target broadcasting device, thereby performing delay processing on the target broadcasting device according to the delay time.

[0086] It should be noted that the above method avoids the negative impact of multiple target broadcasting devices on each other due to the sound superposition effect when broadcasting warning information, thereby effectively improving the broadcast effect of the warning information.

[0087] Optionally, in the control method of the broadcasting equipment provided in the embodiment of the present application, determining the geographic coordinates of the location where the abnormal event occurs includes: obtaining the device parameters of the target image acquisition device, wherein the target image acquisition device is used to acquire video data; and determining the geographic coordinates of the location where the event occurs based on the device parameters of the target image acquisition device and the pixel coordinates of the location where the event occurs in the video data.

[0088] Optionally, the device parameters of the target image acquisition device include but are not limited to the geographic coordinates, installation height, lens focal length, sensor size, pixel size, viewing angle, direction angle, etc. of the target image acquisition device.

[0089] The target processing system can use the sensor size and pixel size of the target image acquisition device to calculate the image plane coordinates of the occurrence location based on the pixel coordinates, and then take into account the viewing angle and focal length of the target image acquisition device, use trigonometric functions and linear transformations to convert the image plane coordinates into real-world spatial coordinates, and then use the inverse conversion method of GPS to convert the spatial coordinates into geographic coordinates.

[0090] Optionally, the pixel coordinates of the above-mentioned occurrence location in the video data may refer to the pixel coordinates of the marking box corresponding to the abnormal event in the target video frame in the video data. The target video frame may be any video frame in which the marking box exists, or it may be the last video frame in the video frames in which the marking box exists.

[0091] It should be noted that, through the above method, the geographical coordinates of the occurrence location are accurately determined.

[0092] Optional, Figure 3 The process of the control method of the broadcasting device provided in the embodiment of the present application is as follows Figure 2 ,according to Figure 3 An optional application process of this embodiment is described. Figure 3 As shown, the preset multiple broadcasting devices are cloud broadcasting devices. The target processing system can pre-determine the location information of each cloud broadcasting device and the sound coverage range of the cloud broadcasting device, and then obtain the video data of the target area in real time, and identify whether there are abnormal events in the video data. When there are abnormal events in the video data, the cloud broadcasting devices are screened based on the geographic coordinates of the location where the abnormal event occurred, the location information of the cloud broadcast, and the sound coverage range of the cloud broadcast to obtain the target cloud broadcasting device, so as to broadcast the warning information corresponding to the abnormal event through the target cloud broadcasting device.

[0093] It can be seen that the solution provided by this application achieves the purpose of dynamically determining the broadcasting equipment used for broadcasting based on the location of the occurrence of the abnormal event, realizes the technical effect of improving the accuracy of reporting of abnormal events, and solves the problem of low accuracy of reporting of abnormal events in related technologies when broadcasting equipment is needed to broadcast abnormal events.

[0094] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
