After the target display screen receives the handheld device packaging event identification, the handheld device packaging event identification is identified based on a local Unity 3D program to obtain a data standardized coordinate, then the data standardized coordinate is converted into a screen coordinate, UI information is updated in an area corresponding to the target display screen, and then the UI information can be synchronously generated when the RFID card is placed.
In an embodiment, after step S102, the method further includes:
and if the target display screen determines that the similarity between the face features in the face feature library stored in the target display screen and the current face features corresponding to the current photo exceeds a preset similarity threshold, identifying the current photo as a verified photo.
In this embodiment, when the photographing function of the target display screen is triggered based on the handheld device 40, after a current photo is acquired based on an image acquisition device (e.g., a camera) on the target display screen, and after a current facial feature is identified and extracted, if it is further determined that the target display screen determines that a similarity between a facial feature in a facial feature library stored in the target display screen and the current facial feature corresponding to the current photo exceeds a preset similarity threshold, it indicates that the photographing based on the target display screen is completed and a facial verification process is performed, and if the accessing user is a pre-specified important user, the playing content (e.g., a specified picture, a text, a video, etc.) corresponding to the user may be displayed on the target display screen.
In an embodiment, before the step S101, the method further includes:
if the user photo is acquired through the image acquisition device, and the similarity between the historical face features stored in the historical face feature library in the intelligent venue central control host and the face features corresponding to the user photo exceeds a preset similarity threshold, intelligent venue navigation track data are generated, and the intelligent venue navigation track data are sent to a user terminal in communication connection with the intelligent venue central control host.
In this embodiment, the RFID-induction-based intelligent venue central control system further includes at least one image acquisition device (e.g., a camera) disposed at an entrance of the intelligent venue, and the image acquisition device can be used to acquire an image of a user entering the intelligent venue and send the image to the central control host for face recognition, so as to determine whether the user entering the intelligent venue is a preset important user who needs to designate reception and guide to visit the intelligent venue. Once it is determined whether the user entering the intelligent venue is a preset important user needing to be appointed to visit and guide to visit the intelligent venue, the intelligent venue navigation track data of the user visiting the intelligent venue at this time can be sent to the user terminal (such as a smart phone) used by the user to guide the user to visit the exhibition hall.
In an embodiment, after the step S101, the method further includes:
and if the handheld device packaging event identifier is determined to correspond to the light control event, the LED lamp strip on the target central control base is correspondingly controlled to be turned on or turned off according to the handheld device packaging event identifier.
In this embodiment, a light control event may also be triggered based on the handheld device, and when it is determined that the handheld device encapsulation event identifier corresponds to the light control event, the LED strip on the target central control base is correspondingly controlled to be turned on or turned off according to the handheld device encapsulation event identifier. Specifically, when the handheld device packaging event identifier is identified by the target central control base for the odd number of times, the LED lamp strip on the target central control base is correspondingly controlled to be started; and when the handheld device packaging event identifier is identified by the target central control base for the second even number of times, correspondingly controlling the turning off of the LED lamp belt on the target central control base. Therefore, the LED lamp strip is flexibly controlled by the user based on the control mode.
The method realizes that the handheld equipment is operated by a user and is close to the central control base to trigger corresponding operation events, and has no requirement on the professional level of operators, thereby reducing the operation difficulty of the central control system of the intelligent venue and improving the interaction degree.
