A visual biometric information collection device and method

Abstract

The present application provides a device for acquiring biometric information, including: an acquisition unit for acquiring an image containing biometric information of an individual to be identified; a display unit for displaying the image acquired by the acquisition unit; feature extraction The unit is used to identify the feature area containing the biometric information of the individual to be identified from the picture acquired by the acquisition unit; the processing unit is used to generate the feature area on the display unit according to the feature area identified by the feature extraction unit. The guide logo; wherein, the guide logo changes as the picture captured by the acquisition unit changes. The method provided by the invention simply and quickly provides direction guidance for the target containing the biometric information to be collected, the operation is quick and clear, the implementation method is simple and low in cost, and the user experience is good.

Description

technical field [0001] The present application relates to the field of biometric identification, in particular, to a visualized biometric information collection device and method. Background technique [0002] Biometric technology and related products have been widely used in user identification and verification / authentication, such as attendance machines, smart locks in the security industry, access control machines, elevator controls, access control products for entrance and exit, parking lot products, and video surveillance products. This biometric identification method can be introduced to achieve the purposes of time management, entrance and exit security control, and people flow statistics. Biometric technology can also be integrated and applied to large-scale software and projects. Specifically, these products can be applied to any environment that requires access control and security control, such as banks, enterprises, institutions, prisons, families, schools, etc.,...

Problems solved by technology

[0004] However, there are also certain problems in non-contact acquisition. For example, the imaging angle of the acquisition equipment is fixed, and the imaging object must be within a suitable range to acquire effective and easily identifiable images.

However, in practice, due to the individual differences of the individuals to be identified and the invisibility of the imaging range, it is difficult to obtain the same image as the image registered in the database, which greatly increases the difficulty of matching and comparison
