Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the specification, as detailed in the appended claims.
The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the description. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present specification. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
With the development of technology, scenes of information display are more and more common in life, and information display modes are more and more. In the case of advertisement, advertisement is a means of publicizing and widely delivering information to the public through a certain form of media for a specific need. Conventional advertisement display media are usually tv, newspaper, radio. With the development of internet technology, advertisements can be displayed through various intelligent devices, for example, the advertisements can be displayed to a user when the user watches videos by using a mobile phone, the advertisements can be displayed through advertisement display devices in a cell elevator room, and the advertisements can be displayed at bus stops by using devices for displaying stop information.
In the related art, an information display party expects to know the actual effect of the displayed information, for example, whether the information is valuable to a user or not and whether the propagation range of the information is wide enough, so that the information display method or the information content can be optimized based on the actual effect, and the user experience is improved.
However, no matter advertisement, news, notification or other information, the practically-oriented people are likely to be uncertain, for example, the information displayed at a bus stop is likely to be watched by people of different ages and professions, such as the old, children, students, white-collar workers, and the like, and the uncertainty is large, so that the determination of the information display effect is challenged.
The specification provides a method for determining an information display effect, which can determine audiences watching information in an information display process and actual watching time of the audiences, so that an accurate information display effect is determined according to the actual watching time.
An exemplary information presentation scenario is first described.
Referring to fig. 1, fig. 1 is a schematic diagram of an information presentation scenario according to an exemplary embodiment of the present disclosure.
The information display scene in fig. 1 includes 3 exemplary information display devices and a server, where the server may be a server or a server cluster, and the information display device may be an information display device in an elevator car, a bus stop information display device, and an outdoor large-screen information display device, and of course, the information display device shown in fig. 1 is only an exemplary description, and the method shown in this specification may also be applied to other devices except the example shown in fig. 1.
The display equipment can communicate with the server through the network, the server can issue information to be displayed to each display equipment, the display equipment can display the information to be displayed after receiving the information, and the information to be displayed can be advertisements, news, broadcasts, notifications and the like, and can also be other information. The present embodiment does not specially limit the number of the display devices, the geographical locations, the types of the devices, and the manner of displaying the information.
Moreover, each display device may be further configured with a camera module, which may be a camera mounted on the device. In the process of displaying the target information, the display equipment can call a camera of the equipment to acquire an environment image stream and upload the environment image stream to the server.
Certainly, if the display device is not equipped with a camera, the camera in the surrounding environment of the display device can be used for collecting the environment image stream, and the environment image stream collected by the camera can be sent to the display device and uploaded to the server side by the display device; or directly sending the collected environment image stream and the corresponding display device identifier to the server, and the server can determine the display device to which the environment image stream belongs according to the identifier. Or the server side can also query the mapping relation between the locally bound display equipment and the camera, and then determine the display equipment to which the environment image stream belongs based on the mapping relation.
After receiving the environment image stream, the server may determine a display effect of the target information based on the environment image stream, which will be described in the following embodiments.
An embodiment of a method for determining an information presentation effect provided in this specification is described below.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for determining an information presentation effect according to an exemplary embodiment of the present disclosure.
The method for determining the information presentation effect may be applied to an electronic device with a memory and a processor, such as a server or a server cluster, and may include the following steps:
And step 206, integrating the display effect of the target information on each audience by each display device to obtain the integrated display effect of the target information.
The above steps are explained in detail below.
In this embodiment, the target information may be displayed through a plurality of display devices. The targeted information may be advertisements, news, broadcasts, notifications, etc. Taking target information as an advertisement as an example, the display device can be an outdoor advertisement screen, an elevator room advertisement display device, a bus stop advertisement display device and the like, and the embodiment does not make special restrictions on the type of the display device, the display place and the number of the display device. Each display device may display only one piece of information, which is the target information, or may display a plurality of pieces of information.
The cameras can be configured on the display devices, the cameras can be called to collect environment image streams in the process of displaying target information, and then the collected environment image streams are uploaded to the server side. The display device may upload the acquired environmental image stream to the server in real time, or may cache the acquired environmental image stream locally, and then periodically send the cached environmental image stream to the server, which is not limited specifically.
In this embodiment, after receiving the environment image stream uploaded by each display device, the server may determine, for each display device, a display effect of the target information under the display device. The following description will take an example of processing an environment image stream uploaded by a display device.
The server can determine a plurality of audiences of the target information and the watching duration of each audience from the environment image stream.
For example, the server may analyze whether a pedestrian exists in the environmental image stream, and if so, may further analyze whether the pedestrian views the target information, for example, may analyze whether the pedestrian views the target information according to a face orientation feature of the pedestrian, and if it is determined that the pedestrian views the target information, it indicates that the pedestrian is a viewer; otherwise, it is stated that the pedestrian is not a spectator. And may also determine a viewing start image frame and a viewing end image frame of the pedestrian from the ambient image stream according to the face orientation features thereof, and determine the viewing duration of the pedestrian based on the time stamps of the two image frames. The details will be described in the following examples.
It should be noted that the pedestrian is not necessarily a walking (moving) person, but may be a stationary person, for example, a stationary person in an elevator car when the elevator car displays information.
In this embodiment, the server may further perform crowd classification on each audience. The people classification can be made from only one dimension, such as whether only the audience's profession is white collar, take out, courier, or student. People may also be categorized from multiple dimensions, such as age, gender, residence, income level, etc. of the audience in addition to categorizing the audience's profession.
In one example, the server may analyze the wearing characteristics and appearance characteristics of the audience from the image frames, so as to analyze the age, gender, occupation, and the like of the audience, thereby implementing the crowd classification. Of course, the server may also use other methods to classify the crowd, and refer to the related art specifically, which is not limited specifically.
In this embodiment, the server may determine the display effect of the target information on each audience according to the crowd classification result and the watching duration of each audience.
For example, the interest level of each type of crowd in the target information may be preset. Assuming that the target information is an advertisement for students but not for white-collar workers, the target information is likely to be more interested by people of the type of "age 10-25 years" and "students", and the target information is likely to be less interested by people of the type of "age 25-50 years" and "white-collar workers", the degree of interest of the audience in the target information can be determined according to the crowd classification result of the audience, the display effect of the target information to the audience is determined according to the degree of interest, and if the determined audience with high interest is more, the effect is better; conversely, the less viewers of high interest, the less effective the result.
In this embodiment, the display effect of the target information on each audience under the display device may be determined by the method, and then the display effect of each audience is integrated to obtain the display effect of the target information under the display device.
And then, the display effect of the target information under each display device can be integrated to obtain the integrated display effect of the target information.
As can be seen from the above description, in an embodiment of the present specification, the server may receive an environmental image stream uploaded by each display device in a target information display process, determine, for the environmental image stream uploaded by each display device, audiences of the target information and watching durations of the audiences based on the environmental image stream, classify the audiences by groups to obtain group classification results of the audiences, determine a display effect of the target information on the audiences based on the group classification results and the watching durations of the audiences, and then synthesize the display effect of the target information on the audiences under each display device to obtain a comprehensive display effect of the target information.
By adopting the method, the information display equipment can collect the environment image stream in the process of displaying the information and upload the environment image stream to the server, the server can determine the audience of the target information and the watching duration of each audience based on the environment image stream, and then determine the display effect of the target information according to the audiences and the watching durations thereof, so that the accuracy of determining the information display effect can be greatly improved, the information display method and the information content can be optimized based on the information display effect, and the user experience can be improved.
An embodiment of another method for determining an information presentation effect provided in the present specification is described below.
Referring to fig. 3, fig. 3 is a schematic flow chart of another method for determining an information presentation effect according to an exemplary embodiment of the present disclosure. The method for determining the information presentation effect can be applied to electronic equipment with a memory and a processor, such as a server or a server cluster.
The method for determining the information display effect may include the steps of:
In this embodiment, the display device may be configured with a camera module, such as a camera, and the image stream of the environment around the display device may be collected by the camera module.
In one example, the display device may continuously invoke the camera module to capture the environmental image stream, and then send the captured environmental image stream to the server. Moreover, the display device may also send a timestamp corresponding to the environmental image stream and the actual playing time of each piece of information to the server, so that the server may determine the environmental image stream corresponding to each piece of information according to the timestamp and the actual playing time. Of course, the server may also determine the environment image stream corresponding to each piece of information in other manners, which is not limited to this.
In another example, when monitoring the playing target information, the display device may also invoke the camera module to collect an environment image stream, and then send the environment image stream and the identifier of the target information to the server. Or the target information may be monitored to be played for a period of time (for example, after 1 second or 2 seconds, the setting may be specifically made in advance), and then the camera module is called to acquire the environmental image stream, which is not particularly limited.
In this embodiment, the server receives the environment image stream uploaded by the display device, and may determine the viewers of the target information and the watching durations of the viewers based on the environment image stream.
For example, the server may extract image frames from the environmental image stream and then identify the image frames to identify whether there is a pedestrian in the image frames. Such as whether a pedestrian is present or not, according to whether the shape of a human body is present or not, and whether a human face is present or not in the image frame.
Of course, in other embodiments, besides the pedestrian may be identified through the environmental image stream, the pedestrian may also be identified by combining other methods, for example, an infrared sensor, a voice sensor, and the like may also be used to assist in determining whether there is a pedestrian in the environment around the display device.
In this example, if a pedestrian is present, it may be further determined whether the pedestrian is a spectator. Taking the advertisement displayed by the elevator car as the target information as an example, the advertisement display device may shoot all pedestrians in the elevator car, but does not represent that all pedestrians are watching the advertisement, and it is meaningless to analyze pedestrians who do not watch the advertisement when analyzing the advertisement display effect, so that it is necessary to distinguish the audience who really watch the advertisement.
For example, the face orientation feature of the pedestrian may be further analyzed based on the image frames to determine the audience for the target information based on the face orientation feature. If the face direction of the pedestrian is opposite to the camera, the pedestrian really watches the target information and is determined as the audience; if the face is oriented to face the camera sideways and away from the camera, it is likely that the pedestrian does not view the target information and is not determined to be a viewer. Of course, besides the face orientation feature of the pedestrian, the eye gazing direction of the pedestrian can also be analyzed, and if the pedestrian gazes at the camera, the pedestrian is determined to be the audience; otherwise, the pedestrian is determined not to be a viewer. The method of analyzing the face direction and the method of analyzing the eye gaze direction may refer to related art, and the present embodiment is not particularly limited thereto.
In this embodiment, after determining the audience of the target information, the viewing duration of the audience may be determined based on the environmental image stream.
For example, an image frame in which the front face of the viewer appears for the first time (viewing start image frame) and an image frame in which the front face of the viewer appears for the last time (viewing end image frame) may be extracted from the environment image stream, and then a time period formed by the two image frames corresponding to the time stamps may be used as the viewing duration of the viewer.
By adopting the method, the audience who really watches the target information and the actual watching time of the audience can be determined, so that the display effect of the target information is analyzed, the relevant data of pedestrians who do not watch the target information does not need to be analyzed, and the accuracy of determining the display effect is improved.
In this embodiment, for each viewer, the image frame where the viewer is located may be extracted from the environmental image stream, and the viewer may be classified into groups based on the image frame.
For example, if the image frame may include many viewers, an image including only the viewers may be cut out from the image frame and then input into the crowd classification model to obtain the crowd classification result of the viewers. The crowd classification result can be multidimensional, for example, the crowd classification can be carried out according to three dimensions of gender, age and occupation, and the crowd classification model can give a prediction score of the audience under each crowd classification type. See table 1 below, where table 1 below illustrates one example of a crowd classification result:
TABLE 1
The crowd classification model may be a neural network model or other models, and is not particularly limited. The method may be obtained by training a large number of images as training samples and crowd classification results as sample labels, and reference may be made to related technologies.
In this embodiment, the crowd classification result of each audience can be expressed in a vector form, and for the audience a in table 1 above, the vector of the crowd classification result can be S a 0.9, {0.1, 0.1,0.1,0.7,0.1,0.1,0.7,0.2 }; for viewer B of Table 1 above, the crowd classification result vector may be S b 0.1,0.9,0.6,0.2,0.1,0.1,0.8,0.1,0.1 }. The presentation effect of the target information may then be calculated based on the vector.
Of course, the above table 1 is only an exemplary illustration, and in practical applications, people may also be classified from other dimensions, and other methods may also be used for people classification, for example, people may also be subjected to face recognition to identify the identity of the audience, and then the relevant information of the identity is obtained through big data to perform people classification.
And 308, determining the value of the target information to the audience according to the value factor corresponding to the target information.
In this embodiment, the information may be classified according to types, for example, the information is taken as an advertisement, and may be classified into a marketing advertisement, a recruitment advertisement, a house property advertisement, and the like, and a value factor corresponding to each type of information may be set, where the value factor is generally a preset interest level of the user in the type of information, that is, a value of the type of information to the user.
The presentation form of the value factor may be a vector, each element in the vector may correspond to each crowd classification type one to one, and the element value may represent the value of the corresponding type of information to the crowd classification.
Still by taking the crowd classification method shown in table 1 as an example, the crowd classification result includes: "male", "female", "5-10 years", "10-20 years", "20-40 years", "above 40 years", "student", "white collar", "courier", assuming that the target information is courier-oriented recruitment information, a corresponding value factor score may be set for each of the above-mentioned category types of people, a higher value factor may be set for a category type matching the target information of "courier-oriented recruitment information", and a lower value factor may be set for a category type not matching the target information of "courier-oriented recruitment information", as shown in table 2 below:
TABLE 2
Of course, the scores of the figure of merit shown in Table 2 above are merely illustrative and are not intended to limit the present disclosure.
The cost factor vector for the example shown in Table 2 above may be W 1 ＝{1,0,0,0.1,0.7,0.4,-0.6,0.5,0.8}。
In this embodiment, the value of the target information to the audience may be determined according to the value factor corresponding to the target information.
For example, the value can be calculated using the following equation (1):
v i ＝S i ·W j (1)
wherein v is i Is the value of the target information j to the viewer i, S i Vector of results of classification of the population of viewer i, W j Is a value factor vector of the target information j.
Still by way of example in tables 1 and 2 above, assuming that the viewer is viewer a, substituting the above equation yields:
v a ＝S a ·W＝{0.9，0.1，0.1，0.1，0.7，0.1，0.1，0.7，0.2}·{1，0，0，0.1，0.7，0.4，-0.6，0.5，0.8}
of course, the above method for calculating the value of the target information to the audience is only an exemplary embodiment of the present specification, and other methods may be adopted to calculate the value of the target information to the audience in practical applications.
For example, in other embodiments, a plurality of corresponding value factors may be set for each information type, each value factor may correspond to one crowd classification type, and when determining the display effect of the target information on the audience, the corresponding value factor may be found according to the crowd classification type to which the audience belongs, where the value factor may be a numerical value or in another form, and then the value of the target information on the audience is determined based on the value factor and the watching duration of the audience.
Still taking the crowd classification results shown in table 1 above as an example, the crowd classification results of viewer a may also be "male", "20-40 years old", or "white-collar". The value factor corresponding to the target information may be determined, for example, if the value factor corresponding to "male" is 0.8, the value factor corresponding to "female" is 0.2, the value factor corresponding to "0-20 years" is 0.3, the value factor corresponding to "20-40 years" is 0.7, the value factor corresponding to "student" is 0.1, the value factor corresponding to "white collar" is 0.9, then the value factor corresponding to viewer a may be found as: 0.8, 0.7, 0.9, which may then be summed, averaged, etc. to derive the value of the target information to the viewer.
And 310, determining the display effect of the target information on the audiences based on the corresponding value and the watching duration of each audience.
In this embodiment, the following formula (2) may be used to calculate the display effect of the target information on the audience:
r i ＝f(v i ，t i ) (2)
wherein r is i Is the effect of the presentation of the target information j to the viewer i, t i The viewing duration of the viewer i. f may be of various forms, for example a first order linear equation, where r i And t i 、v i Respectively, are in positive correlation.
Still by taking the example described in tables 1 and 2 as an example, assuming that the viewer is viewer a and the viewing time of the viewer is 30 seconds, the following formula is substituted to obtain:
r a ＝f(v a ，30)
of course, the above examples are merely exemplary, and other methods may be used to obtain the display effect of the target information in practical applications. In this embodiment, for each display device, the method may be used to calculate the display effect of the target information on each audience under the display device, and then integrate the display effects of the audiences, for example, sum and average to obtain the display effect of the target information under the display device. For example, the display effect of the target information can be obtained by the following formula (3):
and R is the display effect of the target information under the equipment.
And 312, integrating the display effect of the target information on each audience by each display device to obtain the integrated display effect of the target information.
In this embodiment, after the display effect of the target information under each display device is obtained, the display effects of the target information under each display device may be integrated, for example, summing, averaging, and the like, so as to obtain the integrated display effect of the target information. The comprehensive display effect may be in the form of a score or in the form of a grade, such as excellent, good, medium, or poor effect, and is not particularly limited.
By adopting the method, the geographical positions of different display devices may be different, and the facing crowds may also be different, so that the display effect of the target information under different display devices can be integrated, the display effect of the target information on different geographical positions and different types of crowds can be comprehensively and comprehensively analyzed, and the accuracy of determining the display effect is improved.
And step 316, outputting a display adjustment prompt of the target information.
In this embodiment, an expected effect of the target information may also be preset, for example, the expected effect may be determined according to the display cost of the target information, and the expected effect is positively correlated with the display cost. After the comprehensive display effect of the target information is determined, the comprehensive display effect can be compared with the expected effect to judge whether the comprehensive display effect achieves the expected effect.
If the display expectation is not met, a display adjustment prompt of the target information can be output. The display adjustment prompt may prompt the relevant person to adjust the display of the target information, such as adjusting the display time, adjusting the display device of the target information, and so on. And moreover, the number of audiences, the crowd classification result of the audiences, the watching duration of the audiences and the like corresponding to the target information obtained by analysis in the step can be obtained, and the information is also output in the display adjustment, so that related personnel can conveniently formulate a more reasonable information display method, and the user experience is improved.
As can be seen from the above description, in an embodiment of the present specification, each display device may invoke a camera module to collect an environmental image stream in a process of displaying target information and upload the environmental image stream to a server, after receiving the environmental image stream, the server may determine, for the environmental image stream uploaded by each display device, a viewer of the target information and a viewing duration of each viewer based on the environmental image stream, perform crowd classification on the viewer to obtain a crowd classification result of each viewer, obtain a value factor corresponding to each viewer according to the crowd classification result, determine a display effect of the target information on the viewer based on the crowd classification result, the value factor and the viewing duration of each viewer, and then integrate the display of the target information on each viewer under each display device to obtain a comprehensive display effect of the target information.
By adopting the method, the display effect of the target information can be determined according to the real audience and the actual watching duration of the target information, and the influence of pedestrians who do not watch the target information is avoided. In addition, the value factors corresponding to different types of crowds can be determined in advance, so that the influence of the target information on the audience is determined according to the value factors corresponding to the types of the crowds to which the audience belongs, the accuracy of determining the target information display effect can be greatly improved, the information display method and the information content can be optimized based on the information display effect, and the user experience is improved.
Corresponding to the embodiment of the method for determining the information display effect, the specification also provides an embodiment of a device for determining the information display effect.
