With continued reference to FIG. 2, a flow 200 of one embodiment of a method for controlling an output device in accordance with the present application is shown. The method for controlling the output device comprises the following steps:
In the present embodiment, an execution subject (e.g., the controller 105 in fig. 1) of the method for controlling an output apparatus may acquire position information of a target user in response to detecting that the target user takes an article. Wherein the target user may be any user. The target user determination can be specified by a technician or obtained by screening according to certain conditions. As an example, a user entering a supermarket may be set as a target user. The location information may be information related to a location, such as coordinates, addresses, orientations, and the like.
In this embodiment, the execution main body may acquire the location information of the target user in various ways.
As an example, a location (e.g., a shelf) where an item is placed may be provided with multiple sensors. When the user takes the article, the sensor at the original placement position of the article may send a signal containing the sensor identifier to the execution main body. The execution main body can inquire the received sensor identification in a preset corresponding relation table of the sensor identification and the sensor position information. Thereby obtaining sensor position information corresponding to the sensor identification. When the user takes the article, the distance between the user and the sensor at the original placement position of the taken article is short, and the sensor position information obtained by inquiry can be determined as the position information of the target user.
As an example, the execution body may receive location information transmitted from a terminal device used by a target user. Thereafter, the received location information is determined as location information of the target user. Taking a scene that a user enters an unmanned supermarket as an example, the user can use a terminal device (for example, a smartphone with a positioning application installed) to send user information (for example, a user face image, a user identifier, and the like) of the user to the execution main body by scanning a two-dimensional code and the like. And the terminal device can upload the position information of the user to the executive body in the shopping process of the user.
In this embodiment, the execution subject may detect that the target user takes the item in various ways.
As an example, the executing subject may obtain a depth image of the target user and analyze the depth image, thereby detecting that the user takes an item. Specifically, the acquired depth image may be converted into a bone point image. In the skeleton point image, a plurality of points may be used to represent joints of the human body, and these points may also be called joint points. As an example, 20 joint points may be included in the bone point image. On this basis, a technician can set a standard bone point image of the article to be taken. Thereafter, the similarity of the bone point image of the target user and the standard bone point image may be calculated. When the similarity is greater than a preset threshold (e.g., 90%), it may be considered that the target user's taking of the item is detected.
As an example, a location (e.g., a shelf) where an item is placed may be provided with multiple sensors. When the user takes the article, the sensor of the original placement position of the article may send a signal to the execution main body. Therefore, the execution body can detect that the target user takes the article. It should be noted that, at this time, the user who takes the item may be determined as the target user.
As an example, the execution body may first acquire an image containing an image of the user captured by a camera provided in a preset range of an article placement position (e.g., a shelf). Then, the shot image can be input into a pre-trained gesture recognition model, and recognition result information used for representing the gesture category of the user is obtained. In response to the recognition result information representing that the user gesture category is a pickup item, the execution subject may detect that the target user picks up the item. As an example, the gesture recognition model may be obtained by training through the following steps:
in a first step, a set of training samples is obtained. Wherein each training sample may include a sample image and annotation information for the sample image. And the annotation information of the sample image is used for representing the category of the human body posture displayed in the sample image. By way of example, the categories of body gestures may be to take items, to put items down, and the like.
And secondly, acquiring an initial posture recognition model. The initial pose recognition model can be a variety of existing image classification models. By way of example, there may be a Residual Network (ResNet), VGG, and so on. VGG is a classification model proposed by the Visual Geometry Group (VGG) of university.
And thirdly, taking the sample image of the training sample in the training sample set as the input of the initial posture recognition model, taking the marking information corresponding to the input sample image as the expected output of the initial posture recognition model, and training to obtain the posture recognition model. Specifically, a sample image of the training sample may be input to the initial pose recognition model, and recognition result information corresponding to the sample image may be obtained. And calculating the difference between the obtained identification result information and the labeling information by using a preset loss function. Then, based on the obtained difference, parameters of the initial posture recognition model may be adjusted, and in the case that a preset training end condition is satisfied, the training is ended, and the trained initial posture recognition model is used as the posture recognition model. The training end condition includes, but is not limited to, at least one of the following: the training time exceeds the preset time; the training times reach the preset times; the calculated difference is less than a preset difference threshold.
Here, the parameters of the initial pose recognition model may be adjusted in various ways based on the difference between the obtained recognition result information and the labeling information corresponding to the input training sample. For example, a BP (Back Propagation) algorithm or an SGD (Stochastic Gradient Descent) algorithm may be used to adjust the parameters of the initial pose recognition model.
The execution subject of the training step may be the same as or different from the execution subject of the method for controlling the output device. If the two types of the network structures are the same, the executing body can store the network structures and the parameter values of the trained gesture recognition model in the local after the gesture recognition model is obtained through training. If not, after the executing agent of the training step obtains the gesture recognition model through training, the network structure and the parameter values of the model can be sent to the executing agent of the method for controlling the output device.
In this embodiment, the execution subject may determine, as the target output device, an output device that meets a preset condition in the area where the target user is located, based on the location information. The area in which the target user is located may be preset or may be determined according to a certain condition. Taking a scene that a user enters an unmanned supermarket as an example, the area where the target user is located can be preset to be all areas in the supermarket. In addition, the area where the target user is located may also be a fixed-size area with the position where the target user is located as a center and a preset value as a radius.
In this embodiment, the execution subject may determine whether the output device is located within the area where the target user is located by querying the location information of the output device. As an example, the distance between the output device and the target user may be calculated from the coordinates of the output device and the coordinates of the target user. If the calculated distance is less than the radius of the area in which the target user is located, it may be determined that the output device is within the area in which the target user is located.
In the present embodiment, the preset condition may be various conditions. As an example, it may be a preset position at the target user. As an example, it may also be fault-free. Taking the preset condition as no fault as an example, the execution main body may query the state of the output device, so as to determine whether the output device is faulty. Wherein the state of the output device may be entered by a technician. As an example, a fault may be represented by a number "0". No fault is indicated by the number "1". Thus, the execution body may determine an output device in the state of "1" in the area where the target user is located as the target output device.
In this embodiment, upon determining the target output device in step 202, the execution subject may send a control instruction of outputting the target information to the target output device. The target information may be information specified by a technician or information determined according to a certain condition.
In some optional implementations of this embodiment, the method for controlling an output device may further include: acquiring article information of an article; in a preset first output information set, output information associated with the article information is determined. Wherein the output information in the first output information set is associated with the item information. The determined output information is determined as target information.
In some optional implementations of this embodiment, sending a control instruction for outputting the target information to the target output device includes: and sending a control instruction for outputting preset output information to the target output equipment.
In some optional implementations of this embodiment, the method for controlling an output device may further include: and sending a control instruction for stopping outputting the target information to the target output equipment in response to detecting that the distance between the target user and the placement position before the object is taken is greater than a preset threshold value.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for controlling an output device according to the present embodiment. In the application scenario of fig. 3, the item is placed on a shelf 302, the shelf 302 being provided with at least one pressure sensor. The execution subject of the method for controlling the output device may be a backend server 300 of a supermarket. Background server 300 is in communication connection with depth camera 301. The depth camera 301 is used for shooting an image of the shelf 302 and sending a shot depth image 303 to the background server 300. The backend server 300 may analyze the received depth image 303. Specifically, the depth image 303 may be converted into a bone point image 304. The backend server 300 may then calculate the similarity between the skeletal point image 304 and the standard skeletal point image 305 of the picked item. When the calculated similarity is greater than the preset threshold, the background server 300 detects that the user takes the article. Meanwhile, the background server 300 may receive a signal containing a sensor identifier sent by a pressure sensor on the shelf 302. The execution subject may query the sensor identifier in the preset correspondence table 306 between the sensor identifier and the sensor location information. Thereby obtaining sensor location information 307 corresponding to the sensor identification. Since the user is close to the sensor at the original placement position of the article to be picked up when picking up the article, the sensor position information 307 obtained by the inquiry can be used as the position information of the target user.
Based on the position information 307, the display screen 308 and the sound 309 in the area where the target user is located without malfunction are determined as the target output device. A control instruction to output the target information is sent to the display screen 308 and the sound 309. As an example, the control instruction may control the display screen 308 to display a picture of a beach landscape and the audio 309 to play audio of a sea wave sound.
In the method provided by the above embodiment of the present application, first, in response to detecting that the target user takes an article, the location information of the target user is obtained. And then, based on the position information, determining the output equipment which is in the area where the target user is located and meets the preset conditions as the target output equipment. And finally, sending a control instruction for outputting the target information to the target output equipment. Therefore, when the target user takes the article, the target output equipment can output the target information, and the target information is displayed.
With further reference to FIG. 4, a flow 400 of one embodiment of a method for controlling an output device is shown. The process 400 of the method for controlling an output device includes the steps of:
In this embodiment, the specific implementation and technical effects of step 401 are similar to those of step 201 in the embodiment corresponding to fig. 2, and are not described herein again.
In this embodiment, the execution subject of the method for controlling an output device may determine, as a target output device, an output device whose distance from a target user is the smallest in an area in which the target user is located. As an example, the execution subject may first determine the output devices within the area where the target user is located. On the basis, for the output device in the area where the user is located, the execution main body can acquire the distance between the output device and the target user. And then selecting the output equipment with the minimum distance from the target user. And then, determining the selected output device with the minimum distance from the target user as the target output device.
In step 403, the age and gender of the target user are obtained.
In this embodiment, the execution subject may acquire the age and sex of the target user in various ways.
As an example, the execution subject described above may receive the age and sex of the user transmitted from the terminal device used by the target user. Specifically, taking a scene that a user enters an unmanned supermarket as an example, the user may use a terminal device (for example, a smartphone with a positioning application installed therein) to send user information (user gender, age, and the like) of the user to the execution subject by scanning a two-dimensional code and the like.
As an example, the execution body may acquire an image of the target user. And obtains the age and gender of the target user through facial recognition. It should be noted that the face recognition technology is now widely used in various photographing applications or face recognition applications. In practice, the execution subject may directly call an API (Application Programming Interface) of some items (for example, Oxford item) to identify the image of the user, so as to obtain the gender, age, and the like of the user.
In step 404, output information associated with age and gender is determined in a preset second output information set.
In this embodiment, the execution subject may determine the output information associated with age and gender in a preset second output information set. Wherein the output information in the second output information set is associated with age and gender. The second output information combination may be a collection of various information. Such as text, pictures, audio, etc. It is to be understood that the first and second of the first and second output information sets are only for distinguishing the output information sets, and do not limit the output information sets in any way. In practice, age and gender may be considered as a doublet. And each doublet may have an output information associated with it. The execution subject may match the age and gender of the user in the second set of output information. And obtaining the binary group with the highest similarity to the age and the gender of the user. And output information associated with this two-tuple is taken as output information associated with the age and gender of the user.
In step 405, the determined output information is determined as target information.
In this embodiment, the execution subject may determine the output information associated with the age and sex of the user obtained in step 404 as the target information.
In this embodiment, the executing entity may send a control instruction to the target output device obtained in step 402, so that the target output device outputs the target information.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the method for controlling an output device in the present embodiment obtains the age and sex of the user, thereby obtaining output information associated with the age and sex. Thereby, the relevance and pertinence of the output information to the age and gender of the user are realized.
