In this embodiment, the acquired visitor's feature information is divided into two types of biometric feature information and identity auxiliary feature information, and then local comparison is performed according to the biometric feature information and the local database to quickly obtain the visitor's identity information, If the local comparison fails, compare the visitor's characteristic information with the remote database to obtain the visitor's identity information, wherein the smart doorbell performs intelligent identification to obtain the identity information and preset information of the second preset person used to establish the remote database. Set the feature information, and finally execute the user reminder operation according to the obtained visitor's identity information, and quickly and accurately obtain the visitor's identity information and perform user reminder operations through double data comparison with the local database and the remote database, effectively improving the user's awareness of visitors. Identity reminder experience. In addition, if the comparison with the remote database fails, the comparison ends, and a comparison failure message is output to the user, prompting the customer that the visitor is not matched, for example, the voice output of the indoor unit of the smart doorbell is "comparison failure".
Taking a community as an example, after a certain intelligent doorbell in the community obtains the characteristic information of the visitor, it is preferred to use the biometric feature information and the pre-stored preset personnel information of the intelligent doorbell to perform local comparison, if the local comparison Success, such as the user's friends, colleagues, etc., can be fed back to the user. If the local comparison fails, the above feature information can be uploaded to the cloud server of the community, and the feature information can be compared and analyzed by the cloud server of the community to determine the visitor. Information; if the cloud server of the community also fails to compare, the characteristic information of the visitor can be uploaded to the general cloud server for comparison, so as to prevent dangerous people such as thieves and criminals from approaching the user's home, and the owner of the house will be reminded in time when dangerous people approach the house , and for takeaway personnel or property personnel who are often active in the community, it can also be intelligently identified to avoid false alarms caused by identification errors. The use of smart doorbells for intelligent identification can not only increase the width of visitor identification, but also share the identification results between multiple smart doorbells through cloud servers, further improving the accuracy of visitor identification.
The present embodiment divides the acquired visitor's feature information into biometric feature information and identity auxiliary feature information, and then performs local comparison according to the biometric feature information and the local database to quickly obtain the visitor's identity information, If the local comparison fails, compare the visitor's characteristic information with the remote database to obtain the visitor's identity information. Among them, the smart doorbell performs intelligent identification according to the preset machine learning model to obtain the second preset for establishing the remote database. Personnel’s identity information and preset feature information, and finally perform user reminder operations according to the obtained visitor’s identity information. Through the double data comparison with the local database and the remote database, the visitor's identity information can be quickly and accurately obtained and the user reminder operation can be performed, which effectively improves the user's experience of visitor identity reminder. In addition, if the comparison with the remote database fails, the comparison ends, and a comparison failure message is output to the user, prompting the customer that the visitor is not matched.
The present invention divides the acquired visitor's feature information into two types of biometric feature information and identity auxiliary feature information, and then conducts a preliminary comparison according to the biometric feature information and the first database to quickly obtain the visitor's identity information, If the initial comparison fails, a secondary comparison is performed based on the visitor's characteristic information and the second database to obtain the visitor's identity information, and finally the user reminder operation is performed according to the obtained visitor's identity information, which overcomes the problem of obtaining information based on a single characteristic in the prior art. Visitor identity leads to low identity accuracy, and obtaining visitor identity based on multiple characteristic information leads to technical problems of low identity determination efficiency. Through double comparison, visitor identity information can be quickly and accurately obtained and user reminders can be performed to ensure the speed of identity determination. Under the premise of ensuring the accuracy of identity determination, it can effectively improve the user's experience of visitor identity reminder.
[0083] The above provides a variety of visitor detection methods to improve the diversity of visitor detection methods; it is also possible to use the above-mentioned multiple methods to carry out visitor detection to ensure the accuracy of visitor detection results.
[0096] Step S404, adding the visitor's mark and its feature information to the remote database as the identity information and preset feature information of the second preset person respectively. The smart doorbell uploads the identified characteristic information and identity information of passing personnel, suspicious personnel, dangerous personnel, takeaway personnel, salespersons, courier personnel, property personnel, etc. to the cloud server for storage, which is convenient for subsequent comparisons and smart doorbells. Information Sharing.
[0123] The user reminding operation includes one or more of voice broadcasting of the visitor's identity information, sending the visitor's identity information to the smart mobile terminal of the designated user, and sending alarm information to the designated institution. Specifically, after obtaining the identity information of the visitor outside the door, the indoor unit of the smart doorbell can be controlled to perform voice broadcast, and the voice output of the visitor's identity information is convenient for the user to directly listen to the visitor's identity information; The information is transmitted to the designated user's smart mobile terminal through the network, such as a mobile phone, which is convenient for the user to remotely check the visitors at home; and when the identity information of the visitor outside the door is identified as a dangerous person, the smart doorbell can send an alarm message to the designated community security Or designate the smart terminals of the police at the police station, such as mobile phones or computers, to realize alarm processing and avoid harm to people at home.
[0133] Specifically, the user reminding operation includes voice broadcasting of the visitor's identity information and access information, sending the visitor's identity information and access information to the smart mobile terminal of the designated user, and sending alarm information to one or more of the designated institutions. Specifically, after obtaining the identity information and access information of the visitors outside the door, the indoor unit of the smart doorbell can be controlled to perform voice broadcast, and the identity information and access information of the visitors can be output by voice. In this embodiment, the access information includes access time and number of visits , so that the user can directly listen to the visitor's identity information and access information; it can also be set to transmit the visitor's identity information and access information to the specified user's smart mobile terminal through the network through the smart doorbell, such as a mobile phone, so that the user can remotely view the visitors at home; and When the identity information of the visitor outside the door is identified as a dangerous person, the smart doorbell can send an alarm message to the smart terminal of the designated community security or the police of the designated police station to realize alarm processing and avoid harm to people at home.
