Hypersphere covering of biomimetic pattern recognition method has the features of fast identification,low rate of false recognition,easy implementation,and so on. It is particularly suitable for a number of strong practical applications. In this paper,we study a biomimetic pattern recognition method based on the hypersphere string covering and apply it in a fingerprint attendance system. On the basis of analyzing actual teaching needs,we design a complete hardware and software system for the fingerprint attendance system,in which we collect fingerprint data by fingerprint sensor and preprocess it and then recognize the fingerprint image with the hypersphere string covering algorithm. We realize the function of fingerprint registration,class selection,fingerprint attendance,attendance number records,and so on,in the STM32 embedded system. Experimental results show that the system achieves the desired effect and solves the problem of real-time attendance in the classroom. Hypersphere covering of the biomimetic pattern recognition method is suitable for many applications. Through the examples in this article,we can learn by analogy and replicate the method to other applications.
