Embodiment Construction

[0032] Choose an embedded operating system

[0033]With the advancement of microelectronics technology, the manufacturing cost and sales price of chips have been greatly reduced, while the functions and internal supported ports have been greatly expanded. 16-bit and 32-bit processors have gradually become the mainstream of electronic product design. In order to shorten the product design cycle and running time, make the work more stable, reliable and efficient, and realize the required complex functions, an embedded operating system running on the processor is needed to form a complete system platform. Current embedded operating systems include, Microsoft Windows CE, Nucleus PLUS, pSOSystem, μC / OS-II, μclinux, etc. In principle, all the above systems can be used, and μC / OS-II is preferred for this system. Through cutting, the TCP / IP protocol can be added, and the TFTP protocol can be used for remote data upload and download.

Abstract

The blood vessel recognition method and device is a method for quickly identifying and identifying people with biometric technology, and its operation steps are as follows: a. Blood vessel texture image acquisition: irradiate the collected blood vessel parts with near-infrared auxiliary light, and collect blood vessel texture images ; b. Preprocessing of image texture: use the standard deviation threshold tracking method to separate the background, determine the foreground and background of the image, and then perform binary denoising and refinement; c. The authentication problem is transformed into a point pattern matching problem; d. Establishing a database: when building a file, the point coordinates of the singular point position 转化为 Store the polar coordinates in the database as a file template; e. Feature matching: according to the principle of first locking the reference position and then comparing, when comparing blood vessel textures, use the template stored in the database above and the user PID number to form Original feature data template.

Description

technical field [0001] The invention is a method for quickly identifying and identifying people's identity by using biological identification technology, in particular a method for identifying blood vessels by combining blood vessel identification technology with embedded operating system technology. Background technique [0002] Biometric technology is one of the current research hotspots. At present, there are many biometric technologies that can be used for identity authentication, including: iris recognition, retina recognition, face recognition, signature recognition, voice recognition technology, fingerprint recognition technology, etc. The blood vessel recognition technology in this paper has the same lifetime invariance and stability as the fingerprint recognition technology, so it is a biometric system with good application prospects at present. However, the main reasons why fingerprint identification is still not popular in China and ev...
