Abstract:
A method for fingerprint identification and a terminal are provided. The method includes the follows. Source fingerprint data for fingerprint identification is acquired. Fingerprint data to be processed, whose fingerprint data value in a preset threshold range, is extracted from the source fingerprint data. A feature amplifying process is performed on the fingerprint data to be processed and the fingerprint data amplified is repaired to obtain repaired target fingerprint data. A three-dimensional surface is generated according to capacitance values of pixels of the target fingerprint data, a fingerprint image is simulated via the three-dimensional surface, and the simulated fingerprint image is compared with pre-stored fingerprint verification data. The source fingerprint data is determined to be identified successfully, based on a determination that the simulated fingerprint image matches the pre-stored fingerprint verification data.
