The target area is used to place items.

The embodiments of the present invention provide an information display method, device, computer equipment, and storage medium. Detailed descriptions are given below.

In an embodiment, as shown in FIG. 3, an information display method is provided, which includes the following steps:

S301: Acquire facial feature information of the subject.

Among them, the object can refer to a natural person, a robot, or an animal, etc., and can be one, two, or even multiple (when there are multiple objects, it can be determined whether these objects are target objects respectively). At the same time, objects can refer to consumers who enter a specific area (a specific area can refer to areas such as unmanned vending equipment, unmanned supermarkets, and unmanned freezers, and all objects in the specific area can be detected through video detection technology).

Facial feature information refers to information related to the face of an object, and can refer to information such as facial expression, biological feature information, and facial orientation. The facial feature information of the subject can be obtained through video recognition technology.

Video recognition technology is a relatively mature and stable recognition technology so far, which can realize the recognition of human body, biological body, etc. Video recognition technology uses certain optical modules to obtain environmental images, video information, etc., and uses image analysis and other technologies to extract the required information in environmental images and video information and make corresponding judgments to make up for the incomprehensibility of conventional recognition technology . The current video recognition technology includes face recognition, video recognition, image recognition, text recognition, behavior recognition, iris recognition, eyeball focus positioning and other recognition technologies. The video detection technology can be realized by a detector, etc. The detector can also be a camera installed in a specific area, etc., or a mobile terminal of the object, etc. In addition, the video recognition technology can be applied to various embodiments of the present invention, that is, facial feature information, physical feature information, behavior feature information, etc. of an object can be acquired through the video recognition technology.

The step of obtaining facial feature information of an object includes: obtaining physical feature information of the object; when it is determined according to the physical feature information that the type of the object matches a preset type, obtaining the facial feature information of the object. Among them, the body feature information can refer to the height, weight, body shape and other information of the object. The preset types can refer to types such as people, animals, and objects. According to physical characteristics information such as height, weight, body shape, etc., it can be determined whether the object is a person, animal or object, which can effectively avoid misjudgment caused by obstacles such as shopping carts. In addition, judging whether the type of the object matches the preset type can also be performed by other methods other than the physical feature information, for example, it can be performed by a sensor, an infrared detector, a thermal imager, or the like.

S302: When it is determined according to the facial feature information that the face orientation of the object is consistent with the direction where the target area is located, acquire the distance between the object and the target area.

Among them, the target area may refer to the area where unmanned vending equipment, unmanned supermarket, unmanned freezer, etc. are located. An unmanned freezer can be a storage device such as a refrigerated freezer, a freezer freezer, etc. that can store related physical products. The display part can be divided into different commodity layout areas and compartments. At the same time, the freezer can have a glass door or a doorless structure.

If it is determined that the subject's face is in the same direction as the target area, it can indicate that the subject is looking at the direction of the target area. Then the object may be interested in the products displayed in the target area and the information displayed. Next, the distance between the object and the target area can be determined, and it can be determined whether the object moves toward the target area after viewing the goods, information, etc. in the target area.

In addition, the distance between the object and the target area may refer to the outermost distance between the object and the target area, or the distance between the object and the center position of the target area.

S303: When the distance satisfies a preset condition, determine that the corresponding object is the target object.

The preset condition that the distance needs to meet may be that the distance is greater than or less than a certain threshold. If the preset condition is less than a certain threshold, it means that the target object needs to move toward the target area and be close to the target area.

S304: Determine the first display information according to the location of the target object, and display the first display information to the target object.

Wherein, the position of the target object may be within the target area, may also be a certain position close to the target area, or may be a certain position related to the target area. The first display information may be information related to the target area, item information of items displayed in the target area, or promotion information.

In addition, before S304, the step of establishing a binding relationship between the location of the target object and the first display information may also be included. After the binding relationship is determined, when the location of the target object is determined, the corresponding first display information can be determined according to the binding relationship. The first display information determined according to the location of the target object can be considered as information that the object is interested in.

The first display information can be displayed through the display in FIG. 2.

In this embodiment, the target object can be accurately determined according to the interaction process between the object and the target area, and the information of the target object can be displayed accurately.

In one embodiment, before the step of obtaining the distance between the object and the target area, the method further includes: obtaining second display information, and displaying the second display information to the target object; Approaching the target area according to the second display information.

Among them, the second display information refers to information related to the target area. It can be the item information of the items stored in the target area, or it can be promotional information. Further, the second display information may be information that can prompt the object to move in the direction where the target area is located. Taking the freezer as the target area as an example, the second display information can be welcome information, or it can be a list of products stored in the freezer, promotional information, best-selling product information, etc. If the subject is interested after seeing this information, they will go to Move in the direction of the freezer.

If the second display information refers to item information, the item information can be information pre-stored in the memory, or item information obtained in real time through video detection technology; and different types of items in the target area can be fixed Location storage, you can also change location storage.

In addition, the first display information and the second display information may be the same information or different information. The first display information and the second display information can be displayed on the display in FIG. 2.

After acquiring the second display information, it also includes the steps of acquiring the object's biological feature information, physical feature information, behavior feature information, and other video detection information, and binding and storing the video detection information with the second display information. When the object matching the video detection information is located in the specific area again, the second display information can be determined and displayed directly according to the stored binding information, without the need to go through the process of facial feature information analysis.

In this embodiment, the second display information is displayed to prompt the object to approach the target area, and the target object can be determined from a large number of objects by interacting with the object instead of displaying information for all objects, which can effectively reduce the waste of advertising resources. At the same time achieve the purpose of precision marketing.

In one embodiment, the step of determining that the corresponding object is the target object when the distance satisfies a preset condition includes: when the distance is less than a preset threshold, determining that the corresponding object is the target object.

Among them, the preset threshold may be 1 meter, 5 meters, 10 meters, or other values.

It can be determined whether the object is the target object according to the change of the distance. For example, if the distance is gradually reduced, it can be determined that the corresponding object moves to the target area and is the target object.

It can also be combined with time to determine whether the object is the target object. For example, if the distance between an object and the target area (although the distance may be greater than the preset threshold) is maintained at a fixed value for more than 1 minute, and the face is always facing the target area, the object may also be determined as the target object. In this case, the first display information may be remote display information pre-stored in the memory.

In this embodiment, the distance is used to determine whether the object moves toward the target area. If it moves, when the distance is less than a preset threshold, it is determined that the object is the target object. The interaction with the object can be used to determine whether the object is the target object, that is, whether the object is a potential customer. In addition, if the object faces the target area but the distance does not meet the preset conditions, it can be determined that although the object faces the target area, but has not made any actual action to move towards the target area, it may just be observed or looked around while walking. A common behavior in the surroundings determines that the object is temporarily not interested in the target area, so the object can be filtered out.

In one embodiment, the target area includes a plurality of target sub-areas; the step of determining the first display information according to the position of the target object includes: when it is determined that the target object is in the first target sub-area, The first display information corresponding to the first target sub-region is determined according to a preset mapping table.

Among them, the target sub-region can be inside the target region, can also be near the target region, or have a certain association relationship with the target region. The preset mapping table may include the mapping relationship between the target sub-region and the items displayed in the target region. In the case of determining the first target subregion, the corresponding item can be determined by querying the mapping table, and the item information of the item can be used as the first display information.

At the same time, determining that the target object is in the first target sub-area can be determined by a sensor set in the first target sub-area. When the sensor senses that an object is approaching and the distance between the object and the target area is less than a preset threshold, it can be considered The object is in the first target subregion. Based on this, the target sub-area can be called a sensing area.

In addition, the display for displaying the first display information may be set in the target sub-area, for example, may be set on a display screen in each compartment of the freezer, and each display screen correspondingly displays the item information of a freezer sub-area. Of course, the information of different target sub-regions can also be collectively displayed on one display. The embodiments of the present invention do not limit the number and installation positions of the displays.

Taking the target area as a freezer as an example, as shown in Fig. 4, there are three target sub-areas 1/2/3 near the freezer, and the three target sub-areas have corresponding A/B/C freezer sub-areas. There is a corresponding relationship between the three target sub-regions 1/2/3 and the A/B/C freezer sub-region. For example, when the target object stands in the target sub-region 1, the mapping table is used to determine the corresponding to the target sub-region 1. The freezer area is A, and the first display information is determined according to the items stored in the freezer area A.

In this embodiment, the first display information corresponding to the target subregion is determined according to the mapping table, and the first display information that needs to be displayed can be accurately determined according to the position of the target object. Taking the target area as the freezer as an example, when the distance between the potential consumer and the freezer meets the condition, the item information (first display information) is displayed in the corresponding area of the freezer. In actual scenarios, not all people facing and moving toward the freezer are potential consumers, and they may just pass by. Therefore, a critical value needs to be added. When the distance between the person and the freezer is already in the sensing area in the delineated area outside the freezer, then the possibility of him passing by is very small, and he is likely to be really interested in the freezer items. The product information needs to be displayed in the corresponding area of the freezer. By dividing the sensing area outside the freezer, potential consumers who are really interested in the product can be screened out, and then accurate advertising can be carried out to save advertising costs.

In one embodiment, after the step of determining the first display information corresponding to the first target sub-region according to the preset mapping table, the method further includes: determining the video detection information of the target object; The video detection information includes: biological feature information, physical feature information, and behavior feature information; establishing a first temporary association relationship between the video detection information, the first target sub-region, and the first display information.

Among them, biometric information refers to fingerprints, facial features, iris, body shape, and other information that can represent the physiological characteristics of an object. Behavior characteristic information refers to information such as action posture and action range.

In this embodiment, when the target object is in the first target subregion, a temporary association relationship is established between the biometric information, physical characteristic information, and behavior characteristic information of the target object with the first target subregion and the first display information. According to the association relationship, the first display information can be directly determined according to the characteristic information of the target object, which can effectively improve the efficiency of information display.

In one embodiment, after the step of establishing the temporary association relationship between the video detection information, the first target sub-region and the first display information, the method further includes: when the target object moves to the second target sub-region , Disconnect the first temporary association relationship; determine the third display information corresponding to the second target subregion according to a preset mapping table, and display the third display information to the target object; establish the video The second temporary association relationship between the detection information, the second target sub-region, and the third display information.

In this embodiment, when the target object moves to other target subregions, the corresponding third display information is determined according to the target subregion where it is located, and the previously displayed first display information is replaced, and the target can be displayed according to the behavior of the target object The information that the object is interested in prevents the display of invalid information, so as not to waste resources.

In order to better understand the above method, take the target area as the freezer (the freezer contains three freezer sub-areas A/B/C, and corresponds to the three target sub-areas of 1/2/3), and the target is the consumer as an example. An application example of the information display method of the present invention is described in detail.

1. Consumers A and B enter the area that can be detected by the video detection technology, and obtain the physical characteristics information of the consumers A and B through the video detection technology.

2. When the processor determines that the consumer A is a human according to the physical characteristic information, acquire the facial characteristic information of the consumer A.

3. When it is determined that the consumer A is facing the freezer according to the facial feature information, the promotion information of the goods displayed in the freezer is obtained, and the promotion information is displayed on the display; so that the consumer A will approach the freezer after seeing the promotion information.

4. Obtain the distance between consumer A and the freezer in real time.

5. When consumer A moves toward the freezer and the distance from the freezer is less than 5 meters, it is determined that consumer A is the target consumer.

6. When it is determined that the consumer A is in the target sub-area according to the sensor set in the target sub-area 1, the product information of the products in the freezer sub-area A is obtained and displayed on the display set in the freezer sub-area A.

7. When the consumer A moves from the target sub-area 1 to the target sub-area 2, the product information of the products in the freezer sub-area B is obtained and displayed on the display set in the freezer sub-area B.

In this embodiment, after the consumer is determined to be a human, it is determined whether the consumer is facing the freezer according to the facial feature information of the consumer; if so, promotion information is displayed to attract the consumer to move toward the freezer; and when the consumer arrives When the target sub-area, the corresponding product information is displayed. It can determine whether the object is a potential consumer based on the object's behavior, and display the product information of interest to achieve precision marketing.
