[0002] The main significance of exhibitions is to promote exchanges and display the quality of the exhibited objects, so as to promote better exchanges and communication. As a medium for information exchange, the setting of booths and showcases is particularly important. It is not only a platform for conveying information to peers, partners and consumers, but also an important factor in the success of the exhibition. The latest industry trends and technologies can be displayed through booths and showcases.

[0003] In the actual exhibition presentation process, due to the large number of visitors, the visitors' interests and concerns are completely different, which may lead to poor exhibition effects.

[0055] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same 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 disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0056] The essence of the technical solution of the embodiment of the present application is explained in detail below with reference to the accompanying drawings.

[0057] Figure 1 A schematic diagram showing a flow chart of an output control method for multiple display units based on a booth according to an embodiment of the present application is shown. Figure 1 As shown, the output control method of multiple display units based on a booth in an embodiment of the present application includes the following steps:

[0058] Step 101, in response to the arrival of the first cycle, multiple image acquisition modules acquire images of respective acquisition areas.

[0059] In the embodiment of the present application, the first cycle may be the image acquisition cycle of the image acquisition module, and the acquisition cycle of the image acquisition module may be set according to the exhibition needs, for example, it may be set to 5 minutes, 2 minutes or 10 minutes, etc. As an example, the image acquisition module may be a depth camera, a binocular camera, a 3D camera, etc. The image acquisition module may be used to obtain the depth information of each object in the acquired image, such as determining its distance, orientation, and other information. In the embodiment of the present application, the image acquisition module is mainly used to determine the visitors for different display units, that is, it is necessary to determine whether the visitors are paying attention to the display unit according to the specific location of the visitors, the angle between their line of sight and the display unit, etc. The visitors determined by the image acquisition module and the display units they are paying attention to may determine the corresponding display content for different display units, realize the personalized needs of the display content, thereby meeting the display needs of different visitors and improving the display effect.

[0060] Step 102, performing object recognition on the images collected in each collection area, determining the human figure in the image, and extracting the biometric information of the human figure, performing identity recognition based on the extracted biometric information, and determining the identity information of the visitor.

[0061] In an embodiment of the present application, based on the image collected by the image acquisition module, face recognition can be performed by using a geometric feature matching method. Specifically, the geometric feature matching method relies on the geometric features of a person's face, such as the shape, size and positional relationship of the eyes, nose and mouth, to recognize the face image. Based on the facial image of the identified object, the distance, angle and proportion between features such as the eyes, nose and mouth are measured to construct a feature vector describing the face, thereby determining the face in the image and the object to be identified. By comparing the feature vectors of different faces, the identity information of the object to be identified is realized. For the face in the collected image, the face in the image can be determined by the feature point method of the image, and for the collected face image, it can be determined based on the image displacement between adjacent frames or multiple frames. After determining the face, facial feature recognition can be performed based on the face image to determine the identity of the object to be identified.

[0062] As an example, a template matching method can also be used to identify a person based on a face image. The template matching method constructs a standard face template, then compares the face image to be identified with the template, and determines whether they belong to the same person by calculating the similarity between the two. Alternatively, face recognition can be performed by machine learning. The machine learning method can automatically learn facial features by training a large amount of face data and build an efficient classification model. In the embodiment of the present application, the machine learning method can adopt the machine learning method of support vector machine (SVM) and artificial neural network (ANN). SVM divides different categories of face data by finding the optimal hyperplane, while ANN learns and recognizes facial features by simulating the connection method of human brain neurons.

[0063] Step 103, determining the location information of the visitors in the image, the distance and azimuth information of each visitor from each display unit; and eliminating duplicate visitors according to the identity information and / or location information of the visitors.

[0064] In the embodiment of the present application, it is also necessary to confirm the location information of each visitor in the image to clarify the distance, azimuth and other information of each visitor from each display unit. Here, since there are a large number of image acquisition modules, there is a situation where the acquisition areas overlap. Therefore, the embodiment of the present application can remove duplicate visitors based on the identity information or location information of the visitors. For example, when the positions of the visitors overlap, or the distance between the position coordinates is less than the set threshold, the positions are considered to overlap, and the overlapping visitors are removed.

[0065] Step 104, obtaining the eye position and head orientation of the visitor in the image, determining the visual range of the visitor based on the eye position and head orientation, and determining the display unit to which the visitor belongs based on the visual range.

[0066] In the embodiment of the present application, the visitor's eye position and head orientation can also be determined based on the visitor's feature recognition to determine the visitor's field of vision, thereby determining which display unit the visitor is currently paying attention to, and determining the visitor to which each display unit belongs.

[0067] Step 105: determining corresponding output display content for each display unit based on the identity information of the visitors to which each display unit belongs.

[0068] In an embodiment of the present application, as an implementation method, a corresponding weight value is attached to each visitor according to the identity information of the visitor; the weight value of the person originally belonging to the display unit is calculated, and the display content output by the display unit is determined based on the person with the largest weight value.

[0069] Alternatively, as another implementation method, the visiting points of interest of the visitors belonging to the display unit are obtained, the number of visitors with the same visiting points of interest is counted, and the display content output by the display unit is determined based on the visiting points of interest corresponding to the largest number of visitors with the same visiting points of interest.

[0070] Step 106: outputting the determined display content through the determined display unit.

[0071] In the embodiment of the present application, after the display content is determined for each display unit, it is output through the corresponding display unit. The display unit can be various display screens and the like.

[0072] In the embodiment of the present application, as an implementation method, in response to the first cycle coming again, the eye position and head orientation of the visitor in the image are re-acquired, the visual range is determined based on the eye position and head orientation, and the display unit to which the visitor belongs is determined based on the visual range. Considering that visitors are constantly moving, it is necessary to consider the changes in the audience of the display unit and dynamically adjust the display content of the display unit in real time. Therefore, it is necessary to continuously collect the location information of the visitor and the display unit he / she is paying attention to in order to adjust the presentation content of the display unit.

[0073] Based on the changes in the visitors belonging to each display unit, the output display content for each display unit is re-determined, and the display content output by the display unit is adjusted.

[0074] In the embodiment of the present application, when the visitor to whom the display unit belongs is re-determined, a corresponding weight value is attached to each visitor according to the identity information of the visitor; the weight value of the person to whom the display unit originally belonged is calculated, and the weight value of the person to whom the display unit is re-assigned is calculated; the display content output by the display unit is determined based on the person with the largest weight value. Here, as an implementation method, the position information of the visitor can be obtained, and the corresponding weight value for the visitor can be determined based on the position information; or, the age information of the visitor can be obtained, and the corresponding weight value can be set for different age groups; or, the gender information of the visitor can be obtained, and the corresponding weight value can be set for visitors of different genders.

[0075] In the embodiment of the present application, by setting the weight value, corresponding display content can be presented to visitors of different identities. For example, for technical R&D personnel, they are more concerned about the technical evolution direction and technical points of the exhibits. For marketing personnel, they may be more concerned about the performance, price and other display contents of the exhibits. For after-sales personnel, they may be concerned about the service life, maintenance and other display contents of the exhibits. Therefore, by identifying the identity information of the visitor, the corresponding display content can be provided to him.

[0076] In the embodiment of the present application, as an implementation method, after the visitor to whom the display unit belongs is re-determined, the visitor's visiting points of interest of the visitor to whom the display unit belongs can be obtained; the number of visitors with the same visiting points of interest is counted, and the display content output by the display unit is determined by the visiting points of interest corresponding to the largest number of visitors with the same visiting points of interest. Here, the visitor's visiting points of interest can be collected and stored in the relevant booth controller in advance, so that after the visitor's identity is identified, his or her points of interest can be determined to determine the relevant display content for him or her.

[0077] In the embodiment of the present application, although the display content is determined for different visitors by identity information or point of interest information, considering that visitors need to fully understand all the information of the exhibits, after determining that a visitor with a specific identity may have been presented with the display content, the same display content will not be repeatedly displayed to the visitor, but the relevant display content that the visitor has not visited will be selected. For example, for a technician, if the technical display content of a set time has been displayed to him, the display content of after-sales, sales, etc. will be displayed to him.

[0078] In the embodiment of the present application, when it is determined that the content of a certain display unit is switched to the display content determined by the newly approached visitor, the display content visited by the newly approached visitor in the previous display unit is used as the display content determined by the current display unit. In addition, the display time of the display content visited by the newly approached visitor in the previous display unit needs to be used as the display start time of the display content determined by the current display unit, so that the newly approached visitor can visit the display content seamlessly and continuously.
