Problems solved by technology

[0006] However, the existing multimodal biometric acquisition equipment is mainly for controlled environments, and has relatively strict restrictions on the range and attitude of the imaging target and the environmental conditions of the imaging scene. At the same time, the existing multimodal biometric imaging equipment once Only the information of one person can be obtained, and the multi-modal biometric characteristics of multiple targets cannot be collected at the same time, and the identification needs of users in complex imaging scenes cannot be met

Abstract

The invention discloses a device for obtaining a complex scene multi-mode biology characteristic image. The device comprises an active multi-element imaging unit, a logic control platform and a parallel data calculation platform, wherein the logic control platform is connected to an active multi-element imaging unit and the parallel data platform is connected to the logic control platform; the parallel data calculation platform comprises a multi-element sense data processing system, a biologic characteristic scene sensing and modeling system, a multimoding biologic characteristic active sensing system and an advanced imaging algorithm processing system. Besides, the invention also discloses a method for obtaining the complex scene multi-mode biology characteristic image. The method and the device for obtaining the complex scene multi-mode biology characteristic image can perform multimoding recognition on the biologic characteristics of the multiple users under the complex scene conditions, satisfies the requirement for identity recognition in the complex imaging scene, and realizes the effective obtaining of the multimoding biologic characteristics of the iris, the human face and the grait.

Description

technical field [0001] The invention relates to the technical fields of optics, computer vision and pattern recognition, and in particular to a method and device for acquiring multi-modal biological feature images of complex scenes. Background technique [0002] At present, with the continuous development of human science and technology, biometric identification technology has been widely used. Biometric identification refers to the science and technology that computers can realize automatic identification by acquiring and analyzing the physiological and behavioral characteristics of the human body. Common biometric modalities include fingerprints, irises, faces, palm prints, hand shapes, veins, handwriting, gait, voice, etc. The biometric information of various modalities of the human body is mainly distributed in the face (face, iris) and hands (fingerprints, palm prints, hand shapes, veins). Compared with hand biometrics, the face and iris features of the human face hav...
