[0054] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0055] The core of the present application is to provide a method, an apparatus, a robot and a medium for a robot to play display content.

[0056] In order to make the person skilled in the art better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0057] The robot mentioned in the present application includes a memory and a processor, the memory stores computer readable instructions, and the processor implements a method for a robot to play display content when executing the computer readable instructions. The robot provided in the present application is generally applied in a restaurant or a shopping mall, and can be fixed or mobile. Figure 1 A structural schematic diagram of a robot is provided in an embodiment of the present application. It should be noted that, Figure 1 is only one implementation in the embodiments of the present application, and does not limit other embodiments of the present application. For example, Figure 1 As shown in the figure, the robot includes a display screen 10 and a detection apparatus 11. The present application does not limit the structure of the robot, the number, shape and mounting position of the display screen 10 and the detection apparatus 11 in the figure, and does not require the type of the detection apparatus 11, but generally includes multiple different types of detection apparatuses 11 for detecting multiple identification features of the target object. Figure 1The display screen 10 in the figure is installed at the body of the robot, and the target object can watch the interactive content in the display screen 10, and the display screen 10 can also be arranged on the back of the robot or on the top of the body of the robot, so that the target object can watch the interactive content from other directions; the figure also includes two detection devices 11, and the detection device 11 generally installed at the bottom of the body of the robot is a depth camera, which is used to obtain the body contour data of the target object; the detection device 11 installed on the top of the body is an RGB camera, which is used to obtain the face data of the target object, and the detection device can also be a sound recognition device, which is used to obtain the sound data of the target object.

[0058] Figure 2 A flowchart of a method for a robot to play display content is provided in the embodiment of the application; as shown in the figure, the following steps are realized when the processor executes the computer readable instructions:

[0059] S10: obtaining at least two recognition features of the target object sent by the detection device;

[0060] Generally, a plurality of detection devices are installed on the robot to obtain corresponding recognition features, and the detection devices can be laser radar, depth camera, RGB camera, sound recognition device, etc., and these detection devices are generally used to obtain the body contour data, face data, sound data, etc. of the target object, and the height data of the target object can also be obtained through the body contour data; when obtaining different recognition features, the specific detection device to be used is subject to the actual situation, and generally one detection device is used to obtain one recognition feature, which is not specifically required here. The detection device can be installed at any position on the robot, and the corresponding data can be obtained as long as it can be obtained well. For example, the laser radar or the depth camera can be installed at the bottom of the body of the robot, and the body contour data of the target object can be obtained, and the laser radar can also be used to detect whether the target object is close, and the robot can start the detection function of the corresponding detection device after the laser radar detects that the target object is close, and obtain the corresponding recognition features. The RGB camera can be installed on the top of the body of the robot, and the specific installation position is subject to the actual situation, because the RGB camera is generally used to obtain the face data of the target object, and it is best to be close to the height of the face; a plurality of RGB cameras can also be installed at different heights of the robot to obtain the face data of target objects of different heights.

[0061] S11: determining the attribute of the target object according to the recognition features;

[0062] The at least two identification features of the target object are acquired by the plurality of detection devices in step S10, and the acquired identification features include but are not limited to facial data, height data, and voice data. The attributes of the target object can be determined according to the identification features, and the attributes of the target object can be the gender and / or age of the target object. The determined age of the target object can be an accurate age value or an age range, and the length of the age range is not limited, and 5 years can be taken as an age range. The gender of the target object can be determined by the facial data and voice data of the target object, because the differences between the faces and voices of men and women are large, and the gender of the target object can be accurately distinguished by the two kinds of data. However, the height range of men and women is large, and it is difficult to distinguish the gender of the target object by the height data. The age of the target object can be determined by the facial data, height data, voice data, and body contour data of the target object. The differences in the faces and timbres of target objects of different ages are obvious, and can be used as a basis for judgment. The body contour data of target objects of different ages is also quite different. For example, the height data obtained from the body contour data of the target object can be used to distinguish the age of the target object. Children are usually short, and adults are usually tall. If the target object is an old person, the shape of the target object can be obtained from the body contour data to determine the corresponding attributes. The above correspondence between the attributes and the identification features is only one scheme given by the embodiments of the present application. In specific implementation, the attributes can be determined according to the corresponding identification features according to the actual situation. If only one kind of identification feature is used as the basis for determining the attributes, the result obtained may not be accurate. Therefore, the attributes of the target object can be determined according to multiple identification features. If the attributes determined by multiple identification features are different, the attributes determined by multiple identification features can be counted, and an optimal result can be selected. The following gives several cases, and the optimal result can be determined according to the several schemes. In the first case, the gender of the target object is determined by multiple identification features, but multiple results are obtained. The result with the highest frequency can be selected as the optimal result. If the frequency of the results of men and women is the same, the identification features can be reacquired. For example, three identification features determine different genders, two of which determine that the gender is male, and one determines that the gender is female. Finally, the gender of the target object is determined to be male. In the second case, the age range of the target object is determined by multiple identification features, but multiple age ranges are obtained. The age range with the highest frequency can be selected as the optimal result. If the age ranges of the multiple results are different, the average value can be taken or the identification features can be reacquired. For example, three identification features determine three age ranges, which are 1 to 5 years old, 5 to 10 years old, and 10 to 15 years old. The average value of the three age ranges can be taken to determine that the age range of the target object is 5 to 10 years old.

[0063] S12: controlling the display screen to play the interactive content corresponding to the attribute.

[0064] The display screen can be installed at any position of the robot, and is usually installed at a middle position of the robot body, so as to conform to the height of most target objects. The size and shape of the display screen are not required, and generally, a large display screen is used for the target object to watch, and multiple display screens can be used for the target object to watch from different angles. After the attribute of the target object is determined, the display screen is controlled to play the interactive content corresponding to the attribute of the target object. For example, when it is determined that the target object is a child, the display screen is controlled to play some child short film materials to attract the child; when it is determined that the target object is a female, the display screen is controlled to play some makeup teaching videos. The two recognition features are obtained to more accurately determine the attribute of the target object, so that the interactive content played by the display screen can better cater to the preferences of the target object.

[0065] The robot provided in the embodiments of the present application includes a display screen and a detection device. When a target object walks to the vicinity of the robot, the detection device on the robot obtains at least two recognition features of the target object, and determines the attribute of the target object, such as the age and gender of the target object, according to the recognition features. The display screen plays interactive content corresponding to the attribute of the target object, which is more likely to interest the target object, and can improve the experience of the target object to the robot. Moreover, the robot uses at least two recognition features, which can more accurately identify the attribute of the target object than using only one recognition feature.

[0066] In specific implementation, the multiple recognition features can influence each other when determining the attribute, and therefore, the order of obtaining the multiple recognition features can better determine the attribute of the target object. When the recognition features of the target object include face data and height data of the target object, the order of obtaining the two recognition features of the target object by the detection device is as follows: obtaining the face data of the target object; determining whether the face data meets a preset condition; if yes, obtaining the height data of the target object; and if no, ending the face data recognition process.

[0067] The acquired identification features include two kinds, one is face data, and the other is height data. In specific application, the face data of the target object can be acquired by using an RGB camera, and it is judged whether the face data meets the preset requirement. The preset requirement can mean that the acquired face data meets the characteristics of a human face, for example, the acquired face data includes the human facial features. If the face data meets the preset requirement, it can be determined that the object scanned by the detection device at this time is a human being, and the height data of the target object can be further acquired to further determine the attribute of the target object. If the face data does not meet the preset requirement, it is not necessary to continue to acquire the height data, and it is not necessary to continue to determine the attribute of the target object according to the face data, that is, the identification of the face data in this round is ended. The above scheme is the case where the identification features only include face data and height data. When the acquired identification features also include sound data, the acquisition sequence can be to acquire the face data first, then acquire the height data, and finally acquire the sound data. When the acquired identification features do not meet the requirement, the subsequent identification features are not acquired.

[0068] In the embodiment, the acquisition sequence of the face data and the height data is described, the face data of the target object is acquired first, and then the height data of the target object is acquired, so that the attribute of the target object can be determined more accurately. When the acquired face data does not meet the preset condition, the height data is not acquired, so that useless data is avoided to be acquired, thereby avoiding resource waste.

[0069] In actual application scenarios, there can be many other objects near the robot, and the detection device will only acquire identification features for human bodies. However, in actual application, objects similar to human body contours and heights can enter the detection range of the detection device, and some detection devices cannot identify whether the detected object is the target object, thereby possibly obtaining incorrect results. Therefore, before the processor executes the computer readable instructions to control the display screen to play the interactive content corresponding to the attribute, the following step is further implemented: calling a body contour judgment model to judge whether the body contour data meets the preset requirement of the human body contour, the body contour judgment model being generated by being trained in advance according to body contour sample data; if yes, the step of controlling the display screen to play the interactive content corresponding to the attribute is entered.

[0070] The scheme provided in the embodiment excludes similar objects near the robot, so that the identification features of the target object can be acquired more accurately, resource waste caused by acquiring the identification features of similar objects is avoided, and invalid identification features are also avoided to be acquired from similar objects, so that when the target object appears, the display screen of the robot plays the interactive content that is not interesting to the current target object.

[0071] In determining the attribute of the target object, appropriate identification features need to be selected for reference. If the identification features are too few, the determined attribute can not be accurate enough. If the identification features are too many, the accuracy of identification can not be increased, and resource waste can be caused. Therefore, the number of selected identification features is not the more the better, and it is more important to select appropriate identification features for reference. The identification features also include voice data of the target object, and the detection device on the robot also includes a voice recognition device. Determining the attribute of the target object according to the identification features includes: calling a height classification model to process the height data to determine the attribute, the height classification model being generated in advance according to height sample data; calling a face classification model to process the face data to determine the attribute, the face classification model being generated in advance according to face sample data; and calling a voice classification model to process the voice data to determine the attribute, the voice classification model being generated in advance according to voice sample data. The order of obtaining the three kinds of identification features can be: obtaining the face data first, obtaining the height data second, and obtaining the voice data last. Each kind of identification feature can utilize the results of the other two kinds of identification features when determining the attribute of the target object.

[0072] The scheme provided in this embodiment increases the voice data of the target object for reference when determining the attribute of the target object, and the three kinds of identification features jointly confirm the attribute of the target object, so that the determined attribute of the target object is more accurate.

[0073] The robot provided in this embodiment includes a body, the body includes a top portion and a side portion extending downward along a periphery of the top portion, and the display screen includes at least two display screens, of which two display screens are arranged on the top portion and the side portion respectively. For the robot including the two display screens, this embodiment provides two different schemes for controlling the two display screens.

[0074] The first scheme is to control the display screens to play interactive content corresponding to the attribute of the target object, which includes controlling the display screen on the top portion and the display screen on the side portion to play the interactive content corresponding to the attribute of the target object. In actual application, the identification features can not include the height data of the target object. When a target object walks to the vicinity of the robot and the attribute of the target object is determined, the two display screens on the top portion and the side portion of the robot can be controlled to play the same interactive content.

[0075] The second scheme is to control the display screens to play interactive content corresponding to the attribute, which specifically includes: controlling the display screen on the side portion to play the interactive content corresponding to the attribute; and after controlling the display screens to play the interactive content corresponding to the attribute, the processor executing the computer readable instructions further implements the following steps: when the height data represents that the height of the target object is greater than a threshold value, controlling the display screen on the top portion to play the interactive content. When the identification features include the height data of the target object, the height of the target object can be obtained therefrom, and the display screen of the corresponding height can be controlled to play the interactive content according to the height of the target object.

[0076] The above embodiments provide two different solutions, the first solution is to control the two display screens of the top and side to play interactive content regardless of the height of the target object; the second solution is to control the display screen of the corresponding height to play interactive content according to the height of the target object. Both solutions can provide a good viewing angle for the target object and improve the viewing experience of the target object.

[0077] The robot provided in the present application can be applied in a shopping mall, and the interactive content played in the display screen can be product information of a merchant. If the target object is interested in the product in the display screen, the robot needs to lead the target object to the location of the merchant. Therefore, after controlling the display screen to play interactive content corresponding to the attribute, the processor executes computer readable instructions to further implement the following steps: if it is detected that the target object is interested in the interactive content, a pre-stored map is displayed; path information from the current location to the target location is determined through the map; and the robot is controlled to move from the current location to the target location according to the determined path information.

[0078] The solution provided in the present embodiment can lead the target object to the corresponding target location when the target object is interested in the interactive content in the display screen, and display a map of the shopping mall to the target object, so that the target object can obtain the location of the target location according to the map. The solution provides a better experience for the target object and avoids the target object from blindly searching for the target location.

[0079] In the above embodiments, the robot needs to lead the target object to the target location, and in this leading process, the target object is at the back of the robot. The display screen of the robot is at least two, of which two are respectively arranged on the front and back of the robot. When the target object is at the back of the robot, the target object cannot watch the display screen on the front. Therefore, when the processor executes computer readable instructions, the following steps are further implemented: if it is detected that the target object is interested in the interactive content, the display screen on the back is controlled to play the interactive content; and the robot is controlled to move from the current location to the target location corresponding to the interactive content.

[0080] The display screen on the front of the robot plays interactive content. If it is detected that the target object is interested in the interactive content, a prompt information can be played on the display screen on the front to prompt the target object to watch the display screen on the back. At this time, the robot can also turn around to face the display screen on the back to the target object and lead the target object from the current location to the target location corresponding to the interactive content.

[0081] The solution provided in the present embodiment can attract the target object to the back of the robot to watch the display screen on the back. Therefore, in the leading process of the robot, the target object is at the back of the robot and can also watch the interactive content, thereby improving the experience of the target object to the robot.

[0082] In specific implementations, using appropriate detection devices to obtain corresponding identification features can bring a multiplier effect. Therefore, the identification features include height data and face data of the target object, and the detection devices include an RGBD depth camera and an RGB camera; and obtaining at least two identification features of the target object sent by the detection devices includes: obtaining the height data sent by the RGBD depth camera, and obtaining the face data sent by the RGB camera.

[0083] The detection device provided in this embodiment can better obtain the identification features of the target object, has high acquisition efficiency, and the obtained data is accurate.

[0084] The attributes of the target object include gender and age, and the target objects of different ages and different genders are interested in different things. Using appropriate identification features to determine the corresponding attributes can achieve good results; wherein the gender of the target object is obtained by calling a trained model to process face data and / or voice data, because the faces and voices of men and women are quite different, the gender of the target object can be accurately distinguished through the two kinds of data, but the height range of men and women is large, and it is difficult to distinguish the gender of the target object through height data. The age of the target object is obtained by calling a trained model to process any one or any combination of height data, face data, body contour data, and voice data, because the features of the age of the target object can be obtained from height data, face data, body contour data, and voice data, the differences in the faces and timbres of target objects of different ages are quite obvious, and can be used as a basis for judgment. The body contour data of target objects of different ages is also quite different, for example, the height data obtained from the body contour data of the target object can distinguish the age of the target object, children are usually short, and adults are usually tall; if the target object is an old person, the shape of the target object can be obtained from the body contour data to determine the corresponding attribute.

[0085] The scheme provided in this embodiment uses appropriate identification features to determine the age and gender of the target object, and the obtained results have high accuracy and high determination efficiency.
