Based on the above, the embodiment of the invention provides an information display method.
The information display method provided by the embodiment of the invention is described below.
Fig. 1 is a flow chart of an information display method according to an embodiment of the invention.
As shown in fig. 1, the information presentation method may include S101-S104, where the method is applied to a server, and specifically shown as follows:
s101, respectively acquiring flight time TOF information and image information of a plurality of users in a preset area.
S102, determining target users according to TOF information and image information of a plurality of users.
S103, determining at least one piece of first target information according to the image information of the target user.

According to the information display method provided by the invention, the target user is determined through the TOF information and the image information of the user, and the targeted target information is provided for the target user according to the image information of the target user, so that the pertinence of information display is improved, and the user experience is improved.
The contents of S101 to S104 are described below:
a specific implementation of S101 will be first described.
In one embodiment, the time of flight TOF information and image information of a plurality of users in a preset area are respectively acquired, where the preset area may be a preset area in front of the information display device by a certain distance, and acquiring the TOF information and the image information of the users in the preset area may help to determine whether the users are target users to interact with each other.
Next, a specific implementation of S102 will be described.
The step of determining the target user according to the TOF information and the image information of the plurality of users may include two implementation methods, and the specific implementation method is as follows.
(1) The steps related to determining the target user according to the TOF information and the image information of a plurality of users in the embodiment of the invention can comprise the following steps:
determining moving speed information of each user according to TOF information and image information of a plurality of users; determining a user corresponding to the moving speed information meeting the preset condition as a first user; the first user is taken as a target user.
According to TOF information and image information of a plurality of users, a coordinate corresponding relation between the image information of each user and the TOF information of each user is established, the human body outline of each user in the image information can be accurately judged, the moving speed of each user is judged, and if the average moving speed of the user in a preset time period is smaller than a preset threshold value, the user can be used as an alternative user of a target user. For example, a user whose average moving speed is lower than 0.5 meters per second in the first 2 seconds of the current time is taken as an alternative user to the target user.
(2) The steps related to determining the target user according to the TOF information and the image information of a plurality of users in the embodiment of the invention can comprise the following steps:
Determining facial information of each user according to TOF information and image information of each user; determining a user corresponding to the face information meeting the preset condition as a first user; the first user is taken as a target user.
According to TOF information and image information of a plurality of users, the coordinate corresponding relation between the image information of each user and the TOF information of each user is established, and the face information of each user in the image information can be accurately judged. Facial information for each user may be determined based on a pre-trained facial recognition model.
The face information here may be face orientation information by which it is judged whether or not it is looking at the information presentation apparatus, and if the output result of the face recognition model is that the user is looking at the information presentation apparatus, it may be an alternative user to the target user. The face information may also be pupil information of the user, whether the user is looking at the information display device may be determined based on an output result of the pupil recognition model trained in advance, and if the output result is that the user is looking at the information display device, the user may be regarded as an alternative user of the target user.
Therefore, through the two implementation methods for determining the target user according to the TOF information and the image information of the plurality of users, the target user can be accurately screened from the plurality of users, and the pertinence of the information display service provided for the target user in the follow-up process is improved.
In order to more precisely determine the target user, after the step of determining the target user in S102, the following steps may be further included:
under the condition that at least two first users are provided, determining the distance between the at least two first users and the information display equipment respectively; the method for using the first user as the target user specifically comprises the following steps: and determining the first user corresponding to the distance meeting the preset condition as a target user.
If the number of the candidate users of the target user determined by the two ways of determining the target user is plural. That is, if the speed information of a plurality of candidate users satisfies the preset condition, or if the face information of a plurality of candidate users satisfies the preset condition, the candidate user closest to the information display device is marked as the target user. Therefore, the target user can be determined more accurately, and accurate interaction service can be provided for the target user subsequently, so that user experience is improved.
In order to improve the information presentation effect, after the step of determining the target user in S102, the method may further include the steps of:
acquiring TOF information of a target user; determining a target distance between the target user and the information display equipment according to TOF information of the target user; and under the condition that the target distance is larger than a preset threshold value, displaying first information on the information display equipment, wherein the first information is used for enabling a user to move towards the direction of reducing the target distance.
And judging the distance between the target user and the information display equipment, judging the signal intensity of the target user through TOF signals, further judging whether the distance between the target user and the information display equipment is too far, and if the distance between the target user and the information display equipment is beyond a threshold range, inputting an image for guiding the target user to move forwards, and guiding the target to actively move forwards. Wherein the image guiding the forward movement of the target user may be a small game or a mobile application augmented reality (Augmented Reality, AR) game. The information display device is used for displaying target information.
For example, the information presentation apparatus displays an image obtained by a camera, and displays a highlighted circle in an augmented reality manner in an optimal recognition range of TOF by AR technology, thereby guiding a target user to actively approach the information presentation apparatus. Therefore, the TOF signals of the user can be better captured, more accurate interaction service is provided for the user, and the information display effect can be improved.
The specific implementation of S103 is then described.
The step of determining at least one first target information according to the image information of the target user in the embodiment of the present invention may include: determining a characteristic label of the target user according to the image information of the target user; and determining at least one piece of first target information according to the characteristic label of the target user.
And carrying out AI portrait according to the image information of the target user to obtain the characteristic label of the target user, and determining at least one first target information according to the characteristic label of the target user. For example, the target information is commodity information, and the commodity information includes commodity name information, commodity advertisement image information, commodity classification information and commodity label information; the commodity label information is characteristic labels of commodities and comprises applicable crowd, applicable age, style, color, size information and the like of clothing commodities.
Therefore, according to the characteristics of the target user, the information highly matched with the characteristics of the target user can be displayed for the target user in a targeted manner, and the information display effect is improved.
Next, a specific implementation of S104 is described.
As an implementation manner of the present application, in order to better display the target information and improve the user experience, after S104, the method may further include the following steps: receiving target action input of a target user; second target information is determined from the at least one first target information based on the target motion input.
The information display device may have a plurality of first target information to be displayed, in order to improve the experience of the user for viewing the information, a manner of multiple display may be adopted, that is, one first target information may be displayed on the display screen at a time, and the user may respectively give action input to the displayed first target information, so as to determine the second target information from at least one first target information. The action input may be a touch screen action input, or may be gesture information of the user, such as "OK" of the hand ratio of the user, and the confirmation is indicated.
The step of receiving the target action input of the target user specifically may include: acquiring TOF information of a whole outline area of a target user; determining TOF information of a local area of the target user according to TOF information of the whole outline area of the target user and a pre-trained user TOF information model; and determining target action input of a target user according to the TOF information of the local area.
Comparing the acquired TOF signals of the whole outline area of the target user with the TOF signals of the human limbs obtained through deep learning to obtain the joint node positions of the main targets, and determining the TOF signals of the local area of the target user, and determining the actions of the target user according to the TOF signals of the local area of the target user in real time.
For example, comparing the obtained TOF signal of the limb outline of the target user with the human limb TOF signal obtained by deep learning to obtain the joint node position of the main target, identifying the arm joint of the main target and further obtaining the TOF signal of the target arm limb, and obtaining the action of the TOF signal of the target arm limb in real time to obtain the action information of the target arm limb. In the subsequent interaction process, the interaction operation is mainly carried out according to the gesture action of the target, and signals which interfere with judgment of the target limb action in the TOF signals can be filtered in advance by the signal filtering, so that the accuracy of target action input identification can be improved in the subsequent interaction process, the interaction information to be expressed by a user can be received more accurately, and the user experience is improved.
The step of acquiring TOF information of the whole outline area of the target user may specifically include: receiving initial TOF information acquired by at least one TOF device; and determining TOF information of the whole outline area of the target user according to the initial TOF information.
The recognizable range of the TOF equipment is enlarged by arranging a plurality of TOF equipment in the direction away from the information display equipment, so that the recognition accuracy of the TOF equipment is improved, and the interaction experience of the target is optimized. For example, for an information display device working outdoors, a plurality of TOF devices can be arranged in a direction away from the information display device, and after signals of all the TOF devices are acquired, a signal acquired by the TOF device with the strongest signal can be selected for limb identification of a user. And multiple groups of signals acquired by the TOF devices can be weighted to obtain more stable signals. Therefore, the recognition accuracy of TOF equipment can be improved, and the interaction experience of the target is optimized.
The step of determining the second target information from the at least one first target information according to the target action input may specifically include: determining a user instruction according to target action input of a target user; and determining second target information from the at least one first target information according to the user instruction.
And comparing the target action input of the target user with the pre-configured action information to determine the interactive content information of the target user, namely a user instruction. If the interactive content information is a switching instruction, switching the information currently displayed on the information display equipment, and if the interactive content information is a confirmation instruction, confirming the information currently displayed on the information display equipment. Further improving user experience.
