System and method for iris identification using stereoscopic face recognition

Abstract

An iris recognition system including three-dimensional face recognition is disclosed, which can use three-dimensional face recognition to identify irises to identify a person to be verified. The system includes: two or more face recognition cameras, which are used to take two or more face images of the person being verified; Recognizing the plurality of facial images captured by the camera, and generating stereoscopic face information according to the plurality of facial images; and one or more iris recognition cameras, controlled by the recognition system to utilize the generated The three-dimensional face information captures the focused iris of the verifier.

Description

technical field [0001] The present invention generally relates to an iris recognition system and method using stereoscopic face recognition, which can recognize iris by using stereoscopic face images to identify an authenticatee. Background technique [0002] As is well known to those skilled in the art, among biometrics technologies for identifying individuals by treating parts of the human body as identification objects, identification technologies such as iris, face, fingerprint, vein, etc. have been independently used. [0003] However, some biometric techniques cannot be used in some people. For example, iris recognition technology cannot be applied to people who cannot keep their eyes open either congenitally or due to disease. Fingerprint identification technology cannot be applied to people with broken fingerprints. Also, face recognition technology cannot be applied to people whose faces have changed due to plastic surgery, etc. Therefore, combinatorial bioassays...

Problems solved by technology

[0010] At the same time, the traditional face recognition technology is realized by using a single camera to capture the face image, so the face image cannot be analyzed in three dimensions

Therefore, this face recognition technology has the following limitations: the position of the pupil can be detected, but the distance information from the pupil to the iris camera required to capture the focused iris image cannot be obtained

[0011] Moreover, conventional iris recognition technology has the disadvantage that the cost of the iris recognition system increases with the use of high-cost focusing cameras

However, since a single face recognition camera is used, the distance from the pupil to the iris recognition camera cannot be obtained, and the user should position his pupil on the optical axis of the camera so that the image is captured near the focal point of the camera
