Method for acquiring human-face image, human-face discrimination and discriminating system

Abstract

The invention discloses a method and system of getting human face images, which use initiative lamp-house to irradiate the token area of human face; during identifying the faces, using electron image collection means used in the initiative lamp house to take photos in order to get corresponding images, and further, transmitting the said images to corresponding electron handle device to take the process of identifying the human faces. The invention can efficiently reduce that the change of light influence on the human face images in different condition of irradiation. On using, using initiative lamp house to irradiate the human faces, so as to preciously identify the faces in various irradiation conditions. In the imaging of the human faces, as the influence of beam intensity of initiative lamp house is stronger than beam intensity of environment lamp-house, hence collected faces' images is most stable, and getting the best results of computer identifying.

Description

technical field [0001] The invention relates to the technical field of computer image recognition and processing, in particular to a face image generation, face recognition method and system thereof, which use active light sources for face illumination during the face recognition process. Background technique [0002] Face recognition is a biometric recognition technology based on computer, image processing, pattern recognition and other technologies. In recent years, especially after the 9.11 terrorist attack on the United States, all countries in the world put safety first. Therefore, face recognition technology has received more attention than before. [0003] Biometric technology is a high-tech identification technology that mainly relies on the physical characteristics of the human body for identity verification. Human body characteristics such as fingerprints, palm prints, iris, deoxyribose nucleic acid (DNA) and facial appearance have the uniqueness and stability inh...

AI Technical Summary

Problems solved by technology

Some of these methods require three-dimensional modeling of the face, while others assume the shape of the face, and these limitations make the operability of face recognition technology greatly reduced, and it is difficult to achieve good results

[0037] In the application of face image recognition technology, a face recognition access control and attendance system has been disclosed, such as Chinese patent ZL99117360.x, but this patent only discloses how to use face image recognition technology to apply in access control and attendance systems , did not conduct in-depth analysis on the effects and stability of face image acquisition, recognition and processing, such as the influence of changes in skin tone, facial hair, hairstyle, glasses, expressions, posture and light

The recognition rate of the scheme is still low in the case of light changes, so its application field is also limited.

[0038] In addition, due to the high recognition rate of iris recognition technology, there is also the use of iris recognition for identity verification, for example, the product of Iridian company in the United States, but the infrared iris image acquisition device is relatively complicated and has high manufacturing cost, so it is widely used in many occasions. limit

Although Chinese patent ZL99110825.6 also discloses a small portable opto-mechanical device, this device also has problems such as use and inconvenient use by users.

Because the iris alignment mark is too small, the user is required to cooperate too closely to adjust the relative angle and position of the eye and the camera device, which is inconvenient to use and operate, resulting in poor user acceptance

In addition, such image acquisition, recognition and processing systems have problems in installation, maintenance and automation control
