Embodiment

[0015] A face recognition method of the present invention comprises the following steps: sending infrared rays to the face, and receiving the reflected light; receiving the reflected light, and drawing a face map according to the reflection time of each reflected light; and recognizing the face according to the face map. Mapping the face based on the reflection time of each reflected ray uses curve fitting. The face is recognized according to the face image by extracting feature points. After extracting the feature points, compare the feature points with the features in the database. If the comparison results are the same, the faces are considered to match. When this embodiment is implemented, it can be used in the dark, and the infrared ray transmission will not produce lighting effects in the dark, which reduces the requirements on the environment.

Abstract

The invention discloses a face recognition method, which comprises the following steps of: sending infrared rays to a face, and receiving reflected light rays; receiving the reflected light rays, anddrawing a facial map according to the reflection time of each reflected light ray; and recognizing the face according to the face map; drawing a facial map according to the reflection time of each reflected light ray, and adopting curve fitting; recognizing the face according to the face map, and extracting feature points; after extracting feature points, comparing the feature points with featuresin a database; and if the comparison results are the same, considering face matching. The face recognition method can be used in the dark, infrared transmission cannot generate the lighting effect inthe dark, and the requirement for the environment is lowered.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a facial recognition method. Background technique [0002] Facial recognition is also known as face recognition, facial image recognition, face recognition, etc., and facial recognition uses a general-purpose camera as an identification information acquisition device. The facial image of the recognition object is obtained in a non-contact manner, and the computer system completes the recognition process after comparing the obtained image with the database image. Facial recognition is a recognition method based on biometrics. Compared with traditional recognition methods such as fingerprint recognition, it has real-time, accurate, high-precision, easy-to-use, high stability, difficult to counterfeit, cost-effective and non-intrusive features, and is easier to be User accepts. [0003] But existing facial recognition uses grayscale processing and cannot be used in the dark. C...
