Abstract

The invention provides a light-adaptive biological metering information collection device, and the device comprises a light-emitting unit which is used for emitting infrared rays to a blocking object, wherein the intensity of the infrared ray emitted by the light-emitting unit can be adjusted; a sensing unit which is used for sensing the infrared rays reflected by the blocking object, and forming an image of the blocking object according to the sensed infrared rays; a brightness analysis unit which is used for extracting the brightness of the image, and analyzing whether the brightness is within a recognizable brightness range or not; and a light supplement adjustment unit which is used for reducing the light intensity of the light-emitting unit when the obtained image brightness exceeds the upper limit of the recognizable brightness range, or else, increasing the light intensity of the light-emitting unit till the image with the brightness being within the recognizable brightness range is obtained. The device can directly extract the brightness of the collected image, adjusts the light of a light source more visually according to the extraction result, and is higher in resolution of the obtained image.

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.,...
