Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
The inventor researches to find that the traditional scheme faces the following problems:
1. ultraviolet disinfection lamp capable of being turned on and off only at night in timing mode
Under the conditions that the service time of elevators in large shopping malls, high-rise communities, hospitals and the like is not fixed but the flow of people is large, whether a human body flows in the elevator or not cannot be judged, disinfection is not timely, and the situation that the human body cannot be disinfected in time after the human body frequently enters and exits in the elevator in a peak period often occurs, for example, a virus carrier may leave the elevator after the surface of an elevator button is contacted, but is not disinfected in time, so that the potential infection risk of the subsequent elevator-taking human body is increased.
2. Can not enter the elevator after being opened and disinfected
The method also has the problem that the human body is injured when the ultraviolet ray disinfection is started at night; for example, the incidence of cataract of human eyes is increased by direct-view ultraviolet lamps, and the immunologic function is reduced; deep damage to genetic factors; skin cancer, and the like. Many elevators and enclosed spaces will therefore choose to be closed temporarily, while at night it is sometimes the case that e.g. emergency patients and elevator overhauls the human body, require normal use of the elevator.
3. Patients who cannot trace back infection
The method also has the personnel information that the patient is always in close contact with the elevator and the closed space after the diagnosis is confirmed, and the epidemic situation can be further spread.
Referring to fig. 1, the present invention provides a sterilization method based on biometric features, based on the problems of the prior art, including steps S01-S02.
In step S01, acquiring a first biometric feature of an image capture target in a preset scene, and acquiring a movement trajectory of the corresponding image capture target according to the first biometric feature; wherein the preset scene comprises at least one of the following: an elevator entrance, an elevator box body, a corridor entrance and exit and the like;
in one embodiment, the biometric features include at least human face features, human body features, and the like.
The image acquisition equipment of accessible setting in the elevator box, elevator mouth isotopography carries out image acquisition, detects whether there is the human body in the image of gathering, if exist, then draws human body characteristic and facial feature. In particular, the body characteristics may include height characteristics, clothing characteristics, body shape characteristics, and the like.
In one embodiment, the extracted biometric features may be stored in the storage module, or the extracted biometric features may be encrypted and stored in the storage module. The storage module may be disposed in a remote server, or may be disposed in an application device associated with a preset scene. For example, the system can be arranged in an elevator, is connected with a built-in processor of the elevator, and stores data such as images and biological identification characteristics; the device can also be arranged in a remote server, and the device is connected with the remote server through a built-in processor of the elevator to read the images and the biological identification features stored in the storage module.
In an embodiment, a time interval may be preset, and multiple frames of images in a preset scene within the time interval are acquired. The multi-frame image can be a continuous frame image or an interval multi-frame image. For example, the opening time of the elevator door is set as a time starting point, and the human face features and the human body features in 3 frames of images at equal intervals are extracted within a time interval of 2 seconds. The specific time interval and the number of frames of the extracted images can be adjusted according to actual conditions.
And judging the moving track of the corresponding person according to the human face feature and/or the human body feature front-back position change of the same person in the continuous multi-frame images. If the preset scene is in the elevator box body and one person A is in the box body, when the elevator door is opened, the situation that the person A moves outwards is judged through the moving track, and then the person A is judged to be ready to leave the elevator.
In one embodiment, the preset scene may be a specific scene or a combination of scenes. As for elevators, the preset scenario may be a combination of an elevator car and an elevator car. The moving tracks of personnel in the elevator box and at the elevator opening can be obtained simultaneously so as to judge the condition that the personnel get in and out of the elevator.
In step S02, controlling the on/off time of the disinfection device according to the action track, and performing disinfection processing on a preset scene through the disinfection device:
in one embodiment, public facilities or places such as elevators, store aisles and the like have large pedestrian flow and need to be disinfected. Disinfection equipment is often installed at these particular locations. Wherein the sterilizing device may comprise an ultraviolet sterilizing device, a microwave sterilizing device, etc.
Take the application of ultraviolet disinfection equipment to an elevator scene as an example:
the image acquisition equipment can be triggered by a preset triggering mechanism to acquire images of scenes such as an elevator opening and the inside of an elevator box body, and the biological identification features of the acquired images are extracted. The trigger mechanism may include a key trigger, a timing trigger, an event trigger, etc. If someone calls the elevator through a key at the elevator entrance, a camera at the elevator entrance can be triggered to acquire an image of the elevator entrance and extract corresponding biological identification features; for the scenes such as shopping malls and the like, 11 pm can be set, after the shopping malls are closed, the ultraviolet disinfection equipment is started regularly to disinfect the elevator entrance buttons, the internal environment of the elevator box and the like; when the infected person with a certain disease is determined to be possibly present in a certain area, the elevator equipment control system in the area is triggered to start the image acquisition equipment of the corresponding scene, namely, the biological identification characteristics of the entering and exiting persons are monitored.
In an embodiment, if it is determined whether the corresponding person leaves the preset scene and no new person enters the corresponding preset scene according to the movement trajectory of the person obtained in step S01, the delayed turn-on time of the ultraviolet disinfection apparatus may be set. If the situation that the person A leaves the elevator when the elevator door is opened is judged through the moving track, and no other person exists in the elevator door and the elevator box body, the ultraviolet disinfection equipment can be set to delay for 1 second after the elevator door is closed, and the disinfection function is started to disinfect the internal environment of the elevator box body.
In one embodiment, when the disinfection operation is being performed in the elevator box, if the current time is the normal business time of a shopping mall, the image acquisition device is triggered to acquire images of scenes such as an elevator opening, so that whether new personnel need to take the elevator or not is judged. If no new person enters a preset scene, continuing to perform disinfection operation; if a new person enters a preset scene, the turn-off time of the ultraviolet disinfection equipment can be set. If the person B enters the elevator entrance through the collected image, and the waiting time reaches a set threshold (for example, 2 seconds, which can be adjusted according to actual conditions), the ultraviolet disinfection equipment is turned off, and the normal function of the elevator is recovered.
In one embodiment, a tracking target data set may be preset, and the face features and/or the body features to be tracked may be stored in a suspicious person database, or the face features and/or the body features to be tracked may be encrypted and stored in the suspicious person database. The tracking target data set can be arranged in a background server, and can also be embedded into internal equipment of the elevator for pre-storage before the elevator leaves a factory. And taking the biological identification features in the preset scene collected in real time as first biological identification features, and taking the features of the person to be tracked in the tracking target data set as second biological identification features.
Further, the extracted first biological identification feature and the stored second biological identification feature can be compared, and whether the target object to be tracked exists in the current preset scene or not can be judged according to the similarity of the extracted first biological identification feature and the stored second biological identification feature. Wherein the target object to be tracked may include a missing child, an established patient of an infectious disease, a heavy criminal, etc. The characteristic comparison process can be real-time comparison, and can also be realized by reading data in the storage module to perform background delay comparison and selecting or setting according to actual conditions.
In an embodiment, the tracking target data set may be updated periodically, and the first biometric feature stored in the storage module may be compared with the biometric feature corresponding to the updated tracking target to determine whether the new tracking target appears in a preset scene, so as to verify the behavior trace of the tracking target.
In one embodiment, when the application scene is a corridor, the moving track corresponding to the first biological identification feature of the corridor and the entrance and exit of the corridor can be used for judging which time period in the corridor is empty, and further controlling the on-off time of the disinfection equipment. And recording the first biological recognition characteristics of the personnel passing through the corridor, and carrying out action track tracing on the target object to be traced.
