1. A fingerprint recognition method, the method comprising: retrieving a first fingerprint image acquired by a fingerprint sensor and a second fingerprint image stored in a database; performing feature extraction on the first fingerprint image acquired by the fingerprint sensor and the second fingerprint image stored in the database with an auto encode decode network to obtain a first fingerprint feature corresponding to the first fingerprint image and a second fingerprint feature corresponding to the second fingerprint image, the first fingerprint feature and the second fingerprint feature having equal dimensionality; performing dimensionality reduction on the first fingerprint feature and the second fingerprint feature to respectively obtain a third fingerprint feature and a fourth fingerprint feature, the third fingerprint feature and the fourth fingerprint feature having equal dimensionality that is smaller than the dimensionality of the first fingerprint feature and the second fingerprint feature; and determining whether the first fingerprint image and the second fingerprint image belong to a same fingerprint according to a cosine distance between the third fingerprint feature and the fourth fingerprint feature.
