Abstract

The present invention relates to an unlocking method and device based on face recognition. The method includes the following steps: a. enabling some pixels in a ranging sensor to detect the brightness change of the environment in real time; b. judging whether the brightness change satisfies the trigger condition The object is approaching; c. If there is an object approaching, wake up the remaining pixels in the distance measuring sensor; d. Identify the approaching object, and choose whether to unlock according to the identification result. The invention can reduce power consumption to realize long-time standby, and can meet the requirement of large-angle monitoring without adding more components.

Description

technical field [0001] The invention relates to an unlocking method and device based on face recognition. Background technique [0002] Door locks usually include mechanical door locks, electronic door locks, password door locks, fingerprint door locks and face recognition door locks. The types of face recognition door locks mainly include monocular face recognition door locks, binocular face recognition door locks, face recognition door locks based on structured light, and face recognition door locks based on TOF depth measurement. Among them, the principle of TOF (Time of Light Flight) is to use the time of flight of light to measure the distance, so that the 3D data of the face can be measured. In this way, the 3D point cloud formed by the TOF camera can be used to realize face recognition based on the three-dimensional three-dimensional space information; the TOF camera can also be installed on the basis of the RGB or IR camera, so that the 3D data measured by TOF can b...
