Abstract

The invention discloses a laser safety control method and device, an intelligent door lock and a storage medium, the laser safety control method is applied to a depth camera, and the method comprises the steps that a speckle image and an infrared image containing a target object are acquired based on the depth camera; distance information of the target object is acquired based on the speckle image or the infrared image, when a target object area in the speckle image is not overexposed, the distance information of the target object is acquired based on the speckle image, and when the target object area in the speckle image is overexposed, the distance information of the target object is acquired based on the infrared image. Obtaining distance information of the target object based on the infrared image; and performing safety control on a laser in the depth camera based on the distance information. Compared with the prior art, the scheme of the invention is beneficial to safe and intelligent control of the laser emitted by the depth camera, and improves the use safety of a user.

Description

technical field [0001] The present invention relates to the field of optical technology, in particular to a laser safety control method, device, intelligent door lock and storage medium. Background technique [0002] With the development of science and technology, face recognition technology has also developed rapidly and is widely used in various fields. At present, face recognition based on face recognition technology is already a common way to verify identity. For example, when using a door lock, the face recognition of the user can be carried out through the depth camera to determine the identity of the user. When the user is the owner of the house when unlocking. [0003] When using a depth camera for 3D live face recognition, it is necessary to emit laser light through a laser to collect images of the user. In the prior art, the depth camera usually continuously emits laser light to obtain corresponding images in real time. The problem with the existing technology i...
