[0052] In order to make the objectives, technical solutions and advantages of this application more clear and understandable, the following further elaborates on this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely used to explain this application and are not used to limit this application.
[0053] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use, and processing of relevant data need to comply with relevant regulations.
[0054] The broadcast method provided by the embodiments of this application can be applied to a broadcast system as Figure 1 shown. Referring to Figure 1 , this broadcast system includes multiple broadcast devices 100, and each broadcast device 100 is equipped with a target detection device 200 and a power amplifier device 300. An image acquisition module is integrated on each target detection device.
[0055] Among them, a processor of this broadcast system is also installed on any one of the multiple broadcast devices 100, which is used to implement the broadcast method applied to this broadcast system.
[0056] Among them, each broadcast device has a target area it faces.
[0057] Among them, the target detection device is used to collect images of the corresponding target area and perform target detection on the images.
[0058] Among them, the power amplifier device is used to play pre-recorded audio in response to the control of the broadcast system. In specific applications, the power amplifier device is an ordinary power amplifier device and is not a professional directional power amplifier device with a directional broadcast function.
[0059] As Figure 2 shown is another schematic diagram of this broadcast system; referring to Figure 2 , each target detection device and each power amplifier device in the broadcast system are communicatively connected to the processor.
[0060] In specific applications, the multiple broadcast devices can be arranged in sequence or in a ring.
[0061] As Figure 3 shown is yet another schematic diagram of this broadcast system. Taking this schematic diagram as an example, the broadcast system is installed on a lamp post, and three broadcast devices in the broadcast system are arranged in a ring along the lamp post.
[0062] It should be noted that Figure 1 、 Figure 2 and Figure 3It is only used to illustrate the broadcast system and does not limit the number and arrangement of broadcast devices in the broadcast system provided by this application, nor the installation of the broadcast system.
[0063] In an exemplary embodiment, as Figure 4 shown, a broadcast method is provided. Taking the method applied to the broadcast system shown as an example, it includes the following steps S402 to S404: Figure 1 shown, a broadcast method is provided. Taking the method applied to the broadcast system shown as an example, it includes the following steps S402 to S404:
[0064] Step S402, when the target detection device of the first broadcast device acquires the image of the first target area and conducts target detection, and determines that there is a target object in the first target area, based on the position of the target object in the first target area, at least one target broadcast device is determined among multiple broadcast devices.
[0065] Among them, the first broadcast device is any one of the multiple broadcast devices.
[0066] Among them, the first target area is the target area faced by the first broadcast device.
[0067] Among them, the target object is an object with a preset behavior. In specific applications, the target behavior can be crossing the road, spitting everywhere, littering, etc.
[0068] Among them, the target broadcast device can be the first target broadcast device and / or the adjacent broadcast devices of the first target broadcast device.
[0069] Specifically, each target detection device acquires the image of the corresponding target area at a preset time interval through the integrated image acquisition module, then conducts target detection on the acquired image to determine whether there is an object with a preset behavior in the corresponding target area. If so, it is determined as the target object, and then the target detection result of the target object (the presence situation of the target object and the position of the target object) is sent to the broadcast system; when the broadcast system detects a target object by any one target detection device (the first target detection device), based on the position of the target object in the first target area faced by the first broadcast device to which the first target detection device belongs, at least one target broadcast device to be controlled for playback is determined among multiple broadcast devices.
[0070] It should be noted that through this step, the target broadcast device is determined according to the position of the target object. Furthermore, when the position of the target object changes, the determined target broadcast device may also change, thus realizing the directional playback of specific objects in the area and improving the directional ability for specific objects in the area.
[0071] Step S404: Control the power amplifier devices of each target broadcasting device to play the audio associated with the target object.
[0072] Wherein, the audio is pre-recorded audio, and the audio is stored in the memory of the power amplifier device.
[0073] Wherein, the audio associated with the target object refers to the audio associated with the preset behavior corresponding to the target object. In specific applications, the audio is used to warn the target object not to perform the preset behavior. For example, warning the target object not to cross the road, not to spit everywhere, not to litter, etc.
[0074] Specifically, the broadcast system determines the power amplifier devices of each target broadcasting device as the target power amplifier devices to be controlled, and controls each target power amplifier device to play the audio used to warn the target object not to perform the preset behavior.
[0075] In specific applications, the preset behavior corresponding to the target object can be one or more. Correspondingly, the audio stored in the power amplifier device can also be one or more; in the case where the preset behavior is multiple, when the broadcast system controls the target power amplifier device, according to the type of the preset behavior of the target object, the audio corresponding to the type of the preset behavior is determined from multiple audios as the audio associated with the target object.
[0076] For example, the preset behaviors include crossing the road, spitting everywhere, and littering. The target power amplifier device stores the audio for warning the target object not to cross the road, the audio for warning the target object not to spit everywhere, and the audio for warning the target object not to litter; if the preset behavior corresponding to the currently detected target object is crossing the road, the broadcast system controls the target power amplifier device to play the audio for warning the target object not to cross the road.
[0077] In the above broadcast method, first, when the target detection device of the first broadcast device in the broadcast system performs image acquisition and target detection on the first target area and determines that there is a target object in the first target area, at least one target broadcast device is determined from multiple broadcast devices based on the position of the target object in the first target area. The broadcast system includes multiple broadcast devices, each of which is equipped with a target detection device and a power amplifier device. Each target detection device is integrated with an image acquisition module. Each broadcast device has a target area it faces. The first broadcast device is any one of the multiple broadcast devices, and the first target area is the target area that the first broadcast device faces. Then, the power amplifier devices of each target broadcast device are controlled to play the audio associated with the target object. In this way, by configuring a target area for each broadcast device and the power amplifier devices carried on each broadcast device, directional broadcasting can be achieved through the corresponding broadcast device for each target area, thereby reducing the noise interference to the surrounding environment. The broadcast system can perform target detection on the corresponding target area through the target detection device to determine the presence of the target object. The broadcast system can determine the target broadcast device that needs to be controlled for playback from multiple broadcast devices based on the position of the target object in the corresponding target area, and then can control the playback of the power amplifier devices of each broadcast device according to the position change of the target object, thereby achieving directional broadcasting for the target object. Therefore, the broadcast method based on the above process improves the directional ability for specific objects in the area.
[0078] It should be noted that in the related art, directional broadcasting is usually achieved based on professional directional power amplifier devices with directional broadcasting functions. However, the cost of professional directional power amplifier devices is often relatively high, while in this embodiment, directional broadcasting is achieved through ordinary power amplifier devices, which can greatly reduce the cost of directional broadcasting.
[0079] In an exemplary embodiment, there is an overlapping area between the target areas faced by two adjacent broadcast devices; as Figure 5 shown in the schematic diagram of each target area, refer to Figure 5 , the shaded part in the target area is the overlapping area.
[0080] As Figure 6 shown, the steps in step S402 above, based on the position of the target object in the first target area, determine at least one target broadcast device from multiple broadcast devices, specifically include the following steps:
[0081] Step S602: When the target object is within the overlapping area in the first target area, determine the moving direction of the target object, and among the adjacent broadcasting devices of the first broadcasting device, determine the adjacent broadcasting device whose overlapping area between the facing target area and the first target area is the overlapping area where the target object is located as the second broadcasting device.
[0082] Step S604: Determine at least one target broadcasting device from the first broadcasting device and the second broadcasting device according to the moving direction.
[0083] Specifically, first, the broadcasting system determines whether the target object is within the overlapping area in the first target area; if the target object is within the overlapping area in the first target area, the broadcasting system further determines the moving direction of the target object based on at least two target detections of the target object by the first target detection device, and among the adjacent broadcasting devices of the first broadcasting device, determines the adjacent broadcasting device whose overlapping area between the facing target area and the first target area is the overlapping area where the target object is located as the second broadcasting device; then, the broadcasting system determines at least one target broadcasting device to be controlled for playback from the first broadcasting device and the second broadcasting device according to the moving direction of the target object.
[0084] As Figure 7 shown is a schematic diagram of the position of the target object in the first target area; refer to Figure 7 , assuming that broadcasting device 2 is the first broadcasting device and the broadcasting system determines that the target object is within the overlapping area in target area 2, then the broadcasting system determines the corresponding second broadcasting device among the adjacent broadcasting devices of broadcasting device 2, namely broadcasting device 1 and broadcasting device 2; assuming that the target object is within the overlapping area corresponding to broadcasting device 2 and broadcasting device 3, then the broadcasting system determines broadcasting device 3 as the second broadcasting device; then, the broadcasting system determines at least one target broadcasting device from broadcasting device 2 and broadcasting device 3 according to the moving direction of the target object.
[0085] In a specific application, the target detection device performs target detection at a preset time interval and sends the target detection results (the presence situation of the target object and the position of the target object) of the detected target object to the broadcasting system; since the target detection results include the position of the target object, the broadcasting system can determine the moving direction of the target object based on at least two target detections of the target object by the first target detection device.
[0086] In this embodiment, the broadcast system can determine whether it is necessary to warn the target object through at least one target broadcast device by whether the target object is located in the overlapping area, so as to determine the second broadcast device that may also be used as the target broadcast device; determining the target broadcast device according to the moving direction of the target object can achieve directional broadcasting to the target object based on the dynamic movement of the target object; therefore, the broadcast method based on the above process improves the directional ability for specific objects in the area.
[0087] In an exemplary embodiment, each target area further includes a non-overlapping area except the overlapping area in the target area; the blank part in the target area is the non-overlapping area.
[0088] As Figure 8 shown, the above step S604, determining at least one target broadcast device from the first broadcast device and the second broadcast device according to the moving direction of the target object, specifically includes the following steps:
[0089] Step S802, when the moving direction is towards the first non-overlapping area in the first target area, determining the first broadcast device as the target broadcast device.
[0090] Step S804, when the moving direction is towards the second non-overlapping area in the second target area and the distance between the target object and the second non-overlapping area is greater than the preset distance threshold, determining the first broadcast device as the target broadcast device.
[0091] Step S806, when the moving direction is towards the second non-overlapping area and the distance between the target object and the second non-overlapping area is less than the preset distance threshold, determining both the first broadcast device and the second broadcast device as the target broadcast devices.
[0092] Wherein, the second target area is the target area faced by the second broadcast device.
[0093] Wherein, the first non-overlapping area is the non-overlapping area in the first target area, and the second non-overlapping area is the non-overlapping area in the second target area.
[0094] Wherein, the distance between the target object and the second non-overlapping area is the distance between the target object and the junction of the overlapping area where the target object is located and the second non-overlapping area.
[0095] Specifically, if the moving direction of the target object is the first non-overlapping area in the first target area, it means that the target object is currently moving towards the first non-overlapping area. Therefore, the broadcast system only needs to warn the target object through the first broadcast device, and then only determines the first broadcast device as the target broadcast device.
[0096] If the moving direction of the target object is the second non-overlapping area in the second target area, and the distance between the target object and the second non-overlapping area is greater than the preset distance, it indicates that the target object is currently moving towards the second non-overlapping area, but is still far from the second non-overlapping area. Therefore, the broadcast system only needs to give a warning to the target object through the first broadcast device, and then only determines the first broadcast device as the target broadcast device.
[0097] If the moving direction of the target object is the second non-overlapping area, and the distance between the target object and the second non-overlapping area is less than or equal to the preset distance, it indicates that the target object is currently moving towards the second non-overlapping area and is already close to the second non-overlapping area. Therefore, the broadcast system needs to give a warning to the target object through the first broadcast device and the second broadcast device, and then determines both the first broadcast device and the second broadcast device as the target broadcast devices.
[0098] For example, refer to Figure 7 , assuming that the target object is located in the overlapping area corresponding to broadcast device 2 and broadcast device 3, if the target object moves towards the non-overlapping area of target area 2, then the broadcast system determines broadcast device 2 as the target broadcast device.
[0099] If the target object moves towards the non-overlapping area of target area 3, but is still far from the non-overlapping area of target area 3, then the broadcast system determines both broadcast device 2 and broadcast device 3 as the target broadcast devices.
[0100] If the target object moves towards the non-overlapping area of target area 3, but is already close to the non-overlapping area of target area 3, then the broadcast system determines broadcast device 3 as the target broadcast device.
[0101] In this embodiment, determining the target broadcast device based on the moving direction of the target object can achieve directional broadcasting to the target object based on the dynamic moving situation of the target object; therefore, the broadcast method based on the above process improves the directional ability for specific objects in the area.
[0102] In an exemplary embodiment, if the moving direction of the target object is neither the first non-overlapping area nor the second non-overlapping area, then the broadcast system compares the first distance between the target object and the first non-overlapping area and the second distance between the target object and the second non-overlapping area, and determines the broadcast device corresponding to the target area to which the non-overlapping area with the smaller distance value belongs as the target broadcast device; for example, if the first distance is less than the second distance, then the broadcast system determines the first broadcast device as the target broadcast device.
[0103] In an exemplary embodiment, the steps in step S402 above, based on the position of the target object in the first target area, determine at least one target broadcasting device among multiple broadcasting devices, and specifically further include the following: When the target object is outside the overlapping area in the first target area, determine the first broadcasting device as the target broadcasting device.
[0104] Specifically, if the target object is outside the overlapping area in the first target area, that is, within the first non-overlapping area in the first target area, it means that the broadcasting system only needs to warn the target object through the first broadcasting device. Therefore, only the first broadcasting device is determined as the target broadcasting device.
[0105] Such as Figure 9 shown is another schematic diagram of the position of the target object in the first target area; referring to Figure 9 , assuming that the target object is in the non-overlapping area of target area 2, then the broadcasting system determines broadcasting device 2 as the target broadcasting device.
[0106] In this embodiment, the broadcasting system can determine the target broadcasting device that needs to be controlled for playback among multiple broadcasting devices based on the position of the target object in the corresponding target area, and then can control the power amplifier devices of each broadcasting device for playback according to the position change of the target object, so as to achieve directional broadcasting to the target object; therefore, the broadcasting method based on the above process improves the directional ability for specific objects in the area.
[0107] In an exemplary embodiment, each target detection device is used to collect an image of the corresponding target area through the integrated image acquisition module; perform target detection on the image; and when it is confirmed through target detection of the image that there is a target object in the target area corresponding to the image acquisition module, send the target detection result of the target object to the broadcasting system.
[0108] Among them, the target detection result at least includes the presence situation and position of the target object.
[0109] The broadcasting method provided by this application specifically further includes the following: When receiving the target detection result sent by any one of the target detection devices, determine that there is a target object in the target area corresponding to any one of the target detection devices; and determine the position of the target object in the target area corresponding to any one of the target detection devices according to the received target detection result.
[0110] Among them, the target area corresponding to the target detection device refers to the target area faced by the broadcasting device to which the target detection device belongs.
[0111] Specifically, each target detection device collects images of the corresponding target area at a preset time interval through the integrated image acquisition module, then performs target detection on the collected images to determine whether there is an object with a preset behavior in the corresponding target area. If so, it is determined as the target object, and then the existence situation and position of the target object are sent to the broadcast system as the target detection result to alert the broadcast system that there is an object with a preset behavior in the corresponding target area; when the broadcast system receives the target detection result sent by any target detection device, it determines that there is a target object in the target area corresponding to the target detection device; since the target detection result includes the position of the target object, the broadcast system can determine the position of the target object in the target area corresponding to the target detection device that sends the target detection result according to the received target detection result, that is, determine whether the target object is located in the overlapping area in the target area.
[0112] In this embodiment, the broadcast system can detect the target object with a preset behavior through the target detection device and determine the position of the target object in the corresponding target area.
[0113] In an exemplary embodiment, as Figure 10 shown, another broadcast method is provided. Taking the method applied to the broadcast system as Figure 1 shown as an example, it includes the following steps:
[0114] Step S1002, when receiving the target detection result sent by the target detection device of the first broadcast device, determine that there is a target object in the target area faced by the first broadcast device.
[0115] Step S1004, determine the position of the target object in the first target area according to the received target detection result.

[0132] In practical applications, refer to Figure 3 , the broadcast system is installed on a lamp post, and the number of broadcast devices in the broadcast system is three, and the three broadcast devices are arranged in a ring along the lamp post.
[0133] In an exemplary embodiment, there is an overlapping area between the target areas faced by two adjacent broadcast devices.
[0134] The broadcast system is further configured to determine the moving direction of the target object when the target object is located in the overlapping area of the first target area, and determine, among the adjacent broadcast devices of the first broadcast device, the adjacent broadcast device whose overlapping area between the target area it faces and the first target area is the overlapping area where the target object is located as the second broadcast device; determine at least one target broadcast device from the first broadcast device and the second broadcast device according to the moving direction.

[0140] To more clearly illustrate the broadcast method and broadcast provided by the embodiments of the present application, the following uses a specific embodiment to specifically describe the broadcast method and broadcast, but it should be understood that the embodiments of the present application are not limited thereto. In one exemplary embodiment, the present application further provides a low-cost 360-degree directional tracking broadcast system based on a three-way power amplifier, which specifically includes the following:
[0141] Such asFigure 3 The broadcast system provided by this embodiment is shown. The broadcast system surrounds the lamp post and consists of three broadcast devices, with one broadcast device every 120 degrees, forming a 360-degree whole. Each broadcast device is equipped with a camera and a power amplifier device.
[0142] Refer to Figure 11 Another schematic diagram of the broadcast system provided by this embodiment, where one of the broadcast devices is equipped with a processor.
[0143] Among them, the camera is used to detect and track moving targets, the power amplifier is used for broadcasting, and the processor is used to execute the broadcast method of the broadcast system.
[0144] The specific implementation process is mainly divided into three steps. Taking the specific scenario of "Don't litter randomly" as an example, the first step is that the camera continuously detects whether there are pedestrians littering in the picture. When a pedestrian littering is detected, a notification message indicating the recognition of a pedestrian littering is generated and sent to the processor. The second step is that when the processor detects the received notification message, it determines which camera sent the notification message, and then notifies the power amplifier device on the corresponding broadcast device to play the pre-recorded content to warn pedestrians not to litter randomly. The third step is that when a pedestrian moves between the areas corresponding to each camera, it will trigger other cameras to send notification messages. The processor makes a decision to determine which power amplifier devices need to play the pre-recorded content.
[0145] In this embodiment, first, the function of directional broadcasting is realized in a low-cost way, greatly reducing the problem of disturbing residents with broadcasts; second, based on the target detection and tracking of the camera, the function of directional broadcasting for the target is realized, achieving precise broadcasting for moving targets.
