Abstract: In order to overcome the problems of large error and long time-consuming in traditional feature recognition methods, this paper proposes a new fingerprint feature recognition method based on deep learning. Firstly, fingerprint identity database is established, and the access control fingerprint image is collected by the modified hardware equipment, and the image pre-processing is realised from two aspects: image screening and morphological processing. In this framework, the fingerprint direction field in the fingerprint image is screened through multiple iterations. The feature points in the fingerprint image of access control are extracted, and the similarity between the image and the information base is calculated. The experimental results show that compared with the traditional recognition method, the recognition speed of the proposed method is improved by about 6.6 seconds on the premise of ensuring the accuracy of recognition.
