[0032] Figure 3This is a flow chart of an advertisement delivery control method based on outdoor advertising equipment according to another embodiment of the present disclosure. DETAILED DESCRIPTION

[0033] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0035] It should be understood that, in the following, "at least one (item)" means one or more, and "plurality" means two or more. "And / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0036] Figure 1 A circuit block diagram of an outdoor advertising device provided by an embodiment of the present disclosure is shown, including a controller such as a microprocessor or a microcontroller, a wireless communication module connected to the controller, a display screen such as an LED display screen, and a camera.

[0037] The wireless communication module is used to send an advertising data request to a remote first server, wherein the advertising data request carries at least an identification of the outdoor advertising device; and receive advertising data corresponding to the identification of the outdoor advertising device returned by the first server in response to the advertising data request.

[0038] Exemplarily, the identifier of the outdoor advertising device may be a unique code. The wireless communication module may be a 4G or 5G communication module, but is not limited thereto. The first server may be linked to the outdoor advertising device through a network such as a 4G or 5G network. Outdoor advertising equipment is usually located in outdoor areas such as roadsides. After being installed, debugged and used, the initial advertising data may be any one or more of the multiple advertising data pre-stored on the first server, or a relatively rough classification selected therefrom, such as advertising data selected based on different installation regions. After receiving the advertising data request from the outdoor advertising device, the first server returns the advertising data corresponding to the identifier of the outdoor advertising device, such as a unique code (such as a code based on the installation region).

[0039] The controller is used to control the display screen to display and play corresponding advertising content based on the advertising data, and at the same time control the display screen to display prompt information, wherein the prompt information is used to instruct the audience user to make a specified gesture action in response to the advertising content.

[0040] Exemplarily, after the outdoor advertising device receives the returned advertising data through the wireless communication module, the controller controls the display screen such as the LED display screen to display and play the corresponding advertising content (not shown) based on the advertising data. The advertising content can be broadcast content such as pictures and videos. In addition, in this embodiment, while playing the advertising content, the display screen is controlled to display prompt information, and the prompt information is used to instruct the audience user to make a specified gesture for the advertising content. The prompt information can be displayed in a part of the display screen, such as the edge position area, but is not limited to this.

[0041] In one example, the prompt information may be text and graphic information, but is not limited thereto. The prompt information instructs, for example, an audience user who has watched the advertisement content to make a specified gesture action for the advertisement content. Exemplarily, in one embodiment, the specified gesture action may include a plurality of different gesture actions such as hand gestures, each of which represents the degree of interest of the audience user in the advertisement content displayed by the outdoor advertising device. For example, the audience user is instructed to make four different hand gestures, which respectively represent the degree of interest such as very interested, interested, average, and uninterested.

[0042] The camera is used to collect image data when multiple audience users make designated gestures. That is, after the prompt information is prompted, the controller controls the camera to collect image data when multiple audience users make designated gestures.

[0043] The controller is further configured to send the image data collected by the camera to the first server through the wireless communication module, so that the first server updates the advertising data corresponding to the outdoor advertising device based on the analysis result of the image data.

[0044] Exemplarily, after the collected image data is uploaded to the first server, the first server analyzes the image data to obtain an analysis result, and updates the advertising data corresponding to the outdoor advertising device based on the analysis result. As an example, the first server can be used as a big data analysis platform, and the analysis result can be the total number of audience users who are "interested" and "very interested" in one or more advertising contents, and determine the advertising content with a total number greater than or equal to a preset number of people to update the advertising data corresponding to the outdoor advertising device, such as retaining the advertising data corresponding to the advertising content with a total number greater than or equal to the preset number of people, or adding advertising data similar to the advertising content with a total number greater than or equal to the preset number of people, and deleting the advertising data corresponding to the advertising content with a total number less than the preset number of people. In this way, after the outdoor advertising device has been installed, debugged and used for a period of time, its corresponding advertising data can be adjusted and updated based on the action feedback data of the audience users in its geographical location.

[0045] The above scheme in this embodiment improves the intelligent advertising delivery of outdoor advertising equipment. It cannot collect user interaction data like Internet advertising (outdoor advertising equipment usually cannot realize operations such as touch and click) to update advertising delivery. While playing the corresponding advertising content, the display prompt information is controlled to instruct the audience to make a specified gesture action for the advertising content. The camera collects image data when multiple audience users make a specified gesture action and sends it to the first server. The first server updates the advertising data corresponding to the outdoor advertising equipment based on the analysis results of the image data, such as the number of people interested in the advertising content. In this way, accurate control of the advertising delivery of outdoor advertising equipment can be achieved, so that personalized advertising can be accurately delivered to its audience after a period of use. In addition, the advertising delivery scheme of this embodiment is simple and easy to implement, and low cost.

[0046] In one embodiment, the wireless communication module may include a SIM card module, and the outdoor advertising device realizes a 4G or 5G communication connection with the first server based on the SIM card module.

[0047] As an example, the SIM card module may include an IoT SIM card, which implements, for example, a 4G industrial computer and provides a 4G networking function. For example, the IoT SIM card can use a highly secure private network provided by an operator, which does not pass through the Internet, so that network attacks can be effectively prevented and the data security of outdoor advertising equipment can be improved, such as preventing the display and playback content from being tampered with.

[0048] That is, in this embodiment, remote control can be performed based on a customized high-security Internet of Things, and heartbeat detection, status collection, data feedback, etc. of the device can be performed regularly and automatically. Device abnormalities can be discovered in time and handled quickly, greatly reducing the manual input in operations.

[0049] In one embodiment, the controller may include an advertisement broadcast control set-top box for implementing one or more operations of advertisement data pre-download, storage, advertisement broadcast, broadcast data collection, and display screen control.

[0050] For example, the display screen control can be operations such as turning the screen on and off, adjusting the brightness, etc. Playback data collection can collect playback time, playback frequency, etc. The advertising broadcast control set-top box can realize operations such as carousel, time sharing, point selection, and insertion of advertisements. Based on the advertising broadcast control set-top box, a variety of rich functions are realized, which facilitates the convenient operation of outdoor advertising equipment. It has the function of pre-issuing and downloading advertising materials, so that the response speed can be improved when switching to display different advertising contents, and automatic and fast switching of advertising can be realized.

[0051] In one embodiment, reference Figure 2 As shown, the outdoor advertising device may also include an edge computing device connected to the camera and the controller. The edge computing device may be an edge computing box. The edge computing device is used to extract target feature information based on the video information of people and / or vehicles passing through the outdoor advertising device within a preset time period collected by the camera, and the target feature information includes feature information of people and / or vehicles. The controller is also used to send the target feature information to the second server through the wireless communication module, and control the display screen to display and play the corresponding target advertising content based on the target advertising data returned by the second server; wherein the target advertising data is an advertising data matched by the second server from multiple pre-stored advertising data based on the target feature information.

[0052] Exemplarily, the pre-stored multiple advertisement data may be provided with tags such as type tags, and each tag may correspond to different target characteristic information. In one embodiment, the characteristic information of the vehicle includes at least one or more of the number, type and brand of the vehicle; and / or the characteristic information of the person includes at least the gender and number of the person.

[0053] Exemplarily, the edge computing box will analyze the video collected from the audience stream to obtain target feature information, such as the number of vehicles, vehicle type (sedan, SUV), vehicle brand, gender of the person, etc. Personalized information of vehicles or personnel is not collected and recorded here, such as license plate numbers, facial features of personnel, etc., which are not collected and will not involve privacy information. The target feature information collected in the acquired video information will be uploaded to, for example, an audience stream information management server such as a second server. In this way, some special information such as target feature information can be fed back to the advertising delivery process in real time to accurately provide different types of advertisements for different audiences, such as pushing luxury goods advertisements to users of luxury brand vehicles, and pushing lubricant and other advertisements to users of freight trucks.

[0054] In this embodiment, edge computing is adopted to first analyze and process the video locally on the outdoor advertising device to extract target feature information, and then the second server matches the corresponding advertising data accordingly. While achieving precise control over the advertising placement of the outdoor advertising device, it improves the processing efficiency of the advertising placement of the outdoor advertising device, reduces the computing burden on the server side, and thus reduces the server cost and complexity.

[0055] In one example, the edge computing device is used to extract target feature information in the video information based on an image recognition model; wherein the image recognition model is obtained by pre-training an original image recognition model based on a sample video.

[0056] In this embodiment, the edge computing device can accurately extract target feature information such as feature information of people and / or vehicles in the video information through the pre-trained image recognition model, and then the second server can accurately match the corresponding advertising data. That is, while improving the processing efficiency of advertising delivery of outdoor advertising equipment through edge computing, it further improves the accuracy of advertising delivery control of outdoor advertising equipment, so as to provide different types of advertisements more accurately for different audiences.

[0057] Specifically, the original image recognition model can be a convolutional neural network model, but is not limited thereto. The training process of the image recognition model can include: constructing a loss function of the original image recognition model, inputting a sample video into the original image recognition model to output the corresponding feature information of a person and a vehicle, iteratively updating the loss value of the loss function based on the feature information of the person and the vehicle and the feature information of the labeled person and the vehicle, until the training is terminated when the loss value of the loss function meets a preset condition; wherein the loss function includes a first loss function and a second loss function, wherein the first loss function represents the difference between the feature information of the labeled person and the vehicle of the sample video and the feature information of the person and the vehicle output by the original image recognition model, and the second loss function represents the deviation between the feature information of the person and the vehicle output by the original image recognition model and the corresponding labeled feature information of the person and the vehicle.

[0058] The image recognition model obtained by the above training method constrains the training from two aspects at the same time during the training process, and the image recognition model finally obtained can more accurately extract the target feature information in the video information, such as the feature information of people and / or vehicles. That is, the edge computing device in this embodiment can more accurately extract the target feature information in the video information, such as the feature information of people and / or vehicles, through the image recognition model obtained in advance by the above training method, and then the second server can more accurately match the corresponding advertising data, that is, while improving the processing efficiency of outdoor advertising equipment advertising delivery through edge computing, it further improves the accuracy of advertising delivery control of outdoor advertising equipment, so as to provide different types of advertisements for different audiences more accurately.

[0059] In one example, the loss value of the loss function is obtained by weighted summing the first loss value of the first loss function and the second loss value of the second loss function and the first weight value and the second weight value; wherein the first weight value represents the weight of the first loss value, the second weight value represents the weight of the second loss value, and the first weight value is greater than the second weight value. In this way, the fusion training can be constrained from two aspects at the same time during the training process, and the image recognition model finally obtained can more accurately extract the target feature information in the video information, such as the feature information of people and / or vehicles. That is, the edge computing device in this embodiment can more accurately extract the target feature information in the video information, such as the feature information of people and / or vehicles, through the image recognition model obtained in advance by the above-mentioned training method, and then the second server can more accurately match the corresponding advertising data, that is, while improving the processing efficiency of outdoor advertising equipment advertising through edge computing, it further improves the accuracy of advertising control of outdoor advertising equipment.

[0060] The above scheme in this embodiment can realize an intelligent outdoor media platform based on mobile Internet management, and perform operations such as uploading and unloading advertisements, data transmission, and scheduling control on the electronic advertising screens deployed outdoors through the 4G / 5G network. At the same time, the advertising screen has intelligent functions such as audience flow analysis, data reporting, and directional control of advertising, which improves the accuracy of advertising control of outdoor advertising equipment.

[0061] It should be noted that although several modules or units of the device for action execution are mentioned in the above detailed description, this division is not mandatory. In fact, according to the embodiment of the present disclosure, the features and functions of two or more modules or units described above can be concretized in one module or unit. Conversely, the features and functions of a module or unit described above can be further divided into multiple modules or units for concretization. The components displayed as modules or units may or may not be physical units, that is, they may be located in one place, or they may be distributed on multiple network units. Some or all of the modules can be selected according to actual needs to achieve the purpose of the disclosed solution.
