Problems solved by technology

[0003] The traditional face recognition technology is mainly based on face recognition of visible light images, but this method has insurmountable defects, especially when the environment is complex or the light changes, the recognition effect will drop sharply, and face recognition of visible light images cannot Distinguish between real faces and photo faces

Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] The present invention mainly aims at the problem that the visible light face recognition is affected by the environment and light, the feature extraction is quite different, and the real person and the photo cannot be distinguished, and proposes a multi-light source face recognition technology combined with near-infrared images.

[0032] as attached figure 1 As shown, a kind of face recognition method provided by the present invention comprises the following steps:

[0033] S01: Obtain the visible light image and the structured light image of the face to be recognized respectively. Wherein, the visible light image is acquired by a CMOS image sensor. The near-infrared sensor encoded by structured light technology obt...

Abstract

The invention discloses a face recognition method, comprising the following steps: S01: respectively acquiring a visible light image and a structured light image of a face to be recognized; S02: using the visible light image and the structured light image to locate the face; S03: separately in the visible light Extract the minimum face area from the image and the structured light image; S04: rectify, register and compress the visible light image and the structured light image respectively; S05: perform a human face analysis on the minimum face area in the compressed visible light image and the structured light image. Face feature extraction; S06: Calculate the similarity between the face features in the visible light image and the structured light image and the face features in the stored information respectively; S07: Calculate the total similarity between the visible light image and the structured light image, and determine the face to be recognized and stored. Information is not the same person. The face recognition device and method disclosed by the invention make full use of the complementary advantages of structured light and visible light to improve the accuracy of face recognition.

Description

technical field [0001] The invention relates to the field of data recognition, in particular to a face recognition device and method. Background technique [0002] The research on face recognition system began in the 1960s, and it really entered the primary application stage in the late 1990s. The key to the success of the face recognition system is whether it has a cutting-edge core algorithm, so that the recognition result has a practical recognition rate and recognition speed. Therefore, the face recognition system is a master of many professional technologies such as artificial intelligence, machine recognition, machine learning, model theory, expert system, video image processing, etc. The realization of its core technology shows the transformation from weak artificial intelligence to strong artificial intelligence. It also has high technical barriers. [0003] The traditional face recognition technology is mainly based on face recognition of visible light images, but...
