AI Technical Summary

Technical Problem

The existing smart door lock technology uses the detection module to determine the user's return situation when going out, which is prone to mistaken opening and cannot accurately identify the user's real action intention, and the tracking accuracy is single.

Method used

By acquiring the working status of the dynamic tracking function in the smart door lock, obtaining video information of the outside door environment, determining the moving trajectory of the target object in the outside door environment, and determining whether the target object has a return intention based on this trajectory. If it exists, control the smart door lock to perform the unlocking operation.

Benefits of technology

It improves the accuracy of door opening judgment, reduces the phenomenon of misopening, and improves the safety and convenience of users using smart door locks.

Abstract

The invention relates to the technical field of intelligent locks, and discloses an unlocking method and device of an intelligent door lock, computer equipment and a storage medium, and the method comprises the following steps: obtaining a working state of a dynamic tracking function in the intelligent door lock; when the working state of the dynamic tracking function is a trigger state, acquiring video information of an outdoor environment; determining a moving track of the target object in the outdoor environment according to the video information; whether the target object has a return intention or not is determined based on the moving track, and if yes, the intelligent door lock is controlled to execute unlocking operation. The intelligent door lock solves the problems that the existing intelligent door lock technology only judges the user going-out return condition through a detection module, errors are large, mistaken door opening is likely to occur, the real action intention of the user cannot be accurately recognized, and the tracking precision is single.
