Embodiment 1

[0029] see Figure 1-4, a controllable biometric information identification device and system, including an installation base 1, a connecting rod 2 and a fixed plate 3, the installation base 1 includes a fixed base plate 101, the connecting rod 2 is fixedly connected to the fixed base plate 101, and the fixed plate 3 Fixedly connected to the top of the connecting rod 2, the fixed bottom plate 101 is fixedly connected with the first connecting ear 102, the first connecting ear 102 is fixedly connected with the connecting shaft 103, the connecting shaft 103 is fixedly connected on the movable bottom plate 104, and the movable bottom plate 104 passes through The connecting shaft 103 is rotationally connected with the first connecting ear 102, and the movable bottom plate 104 is also fixedly connected with an auxiliary pole 105, which matches the connecting rod 2, and the bottom surface of the movable bottom plate 104 is also fixedly connected with a suction cup 106; The bar 2 is ...

Embodiment 2

[0035] see Figure 5 , based on Embodiment 1, the difference is that;

[0036] The biometric information recognition system includes a facial information recognition system and an iris information recognition system, the facial information recognition system is linked with the facial information input module and the facial information identification information module, and the facial information input module and the facial information identification information module are linked to the facial information database , the facial information database is also linked with the two-dimensional facial information recognition module and the three-dimensional facial information recognition module, the two-dimensional facial information recognition module and the three-dimensional facial information recognition module are all linked with the feature extraction module, and the feature extraction module is also linked with the facial feature matching module The iris information identificati...

Embodiment 3

[0039] Based on embodiment 1 or 2, the difference is that;

[0040] The iris information processing system is linked with the iris information quality evaluation module, the iris information quality evaluation module is linked with the iris image denoising module and the iris positioning module, the iris positioning module is linked with the iris image enhancement module and the iris normalization module, the iris image The enhancement module is also linked with the iris normalization module, the iris normalization module is also linked with the iris texture feature extraction module, the iris texture feature extraction module is linked with the iris feature encoding module, and the iris feature encoding module is linked with the iris feature matching module link, a decoding unit is linked between the iris feature encoding module and the iris feature matching module.

[0041] The iris information quality evaluation module uses a sequence quality evaluation algorithm and a comb...

Abstract

The invention discloses a controllable biological information recognition device and system, and belongs to the technical field of detection systems. The controllable biological information recognition device provided by the invention can be adjusted as required, the use is more convenient, and an iris information processing system in the controllable biological information recognition system starts from the perspective of object-oriented design criteria, so that the recognition process achieves the effects of low coupling and high cohesion. Main functions and main algorithms of all stages areexplained in a class diagram mode, and attributes which have important influences on the iris recognition effect and the data transmission relation between all the recognition stages are mainly analyzed. Therefore, a user does not need to know the specific implementation of the algorithm in each stage, information hiding is supported, and the problems that an existing biological information recognition device is usually fixed in structure and inconvenient to use and an existing biological information recognition system is not high in safety and accuracy are effectively solved.

Description

technical field [0001] The invention relates to the technical field of detection systems, in particular to a controllable biological information identification device and system. Background technique [0002] The so-called biometric technology is to use the inherent physiological characteristics of the human body (such as fingerprints, facial images, red membranes, etc.) and behavioral characteristics (such as handwriting, voice, gait, etc.) to carry out personal identification. Traditional identification methods include identification items (such as keys, certificates, ATM cards, etc.) and identification knowledge (such as user names and passwords), but because they mainly rely on external objects, Once the identification items and identification knowledge proving identity are stolen or forgotten, their identity is easily impersonated or replaced by others. [0003] The existing biometric information identification devices on the market are often fixed in structure and inc...
