A fingerprint recognition method includes: acquiring a prestored number of historical defect pixels after a fingerprint recognition sensor captures a first fingerprint image; prohibiting performing matching recognition on the first fingerprint image upon the number of the historical defect pixels being greater than or equal to a first preset number threshold; detecting a number of damaged capturing modules of the fingerprint recognition sensor to obtain a number of current defect pixels; and updating the number of the historical defect pixels by using the number of the current defect pixels, the updated number of the historical defect pixels being used for determining whether to perform matching recognition on a fingerprint image captured next time.
