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 complex scene multi-modal biometric image acquisition device, comprising: an active multi-component imaging unit, a logic control platform, and a parallel data computing platform, wherein the logic control platform is connected with the active multi-component imaging unit for parallel data computing The platform is connected to the logic control platform, and the parallel data computing platform specifically includes a multi-sensing data processing system, a biometric scene perception and modeling system, a multimodal biometric active perception system, and an advanced imaging algorithm processing system. In addition, the invention also discloses a method for acquiring multi-modal biological feature images of complex scenes. The present invention discloses a complex scene multi-modal biological feature image acquisition method and its device, which can perform multi-modal recognition of the biological features of multiple users under realistic complex scene conditions, and meet the identity recognition of multiple users in complex imaging scenes To realize the effective acquisition of multi-modal biometric features of iris, face and gait in a wide range.

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...
