the intelligent door lock acquires the current facial information of an unlocking person according to the image acquisition signal;
the intelligent door lock sends the matching information and the current facial information to the mobile terminal;
and the mobile terminal carries out early warning prompt according to the matching information and the current facial information.
8. The intelligent door lock-based early warning method according to claim 7, wherein the step of locking the key when the matching information does not meet a preset condition comprises the steps of:
the intelligent door lock acquires matching data according to the matching information;
the intelligent door lock judges whether the matching data is smaller than a preset matching threshold value;
and when the matching data is smaller than the preset matching threshold value, the intelligent door lock locks the key.
9. The intelligent door lock-based early warning method according to claim 8, wherein the step of acquiring the current facial information of the person who opens the intelligent door lock according to the image acquisition signal by the intelligent door lock comprises the following steps:
the intelligent door lock acquires a current facial image of a person unlocking the intelligent door lock according to the image acquisition signal within a preset first time threshold value;
the intelligent door lock performs graying processing on the current face image to obtain a grayed image;
and the intelligent door lock obtains a target face image through a preset image processing algorithm according to the gray-scale image.
10. The intelligent door lock-based early warning method according to claim 9, wherein the step of obtaining the target face image by a preset image processing algorithm according to the grayed image comprises:
the intelligent door lock performs marginalization processing on the initial characteristic image to obtain a target characteristic image;
and the intelligent door lock obtains a target face image through a binarization algorithm according to the target characteristic image.
