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.

Claim (Index 6):
The terminal of  claim 5 , wherein the processing module configured to repair the amplified fingerprint data is configured to:\n divide all pixels of the fingerprint module into multiple pixel areas, each pixel area being a designated area and comprising x*y pixels, wherein x and y are natural numbers; for each fingerprint pattern in a designated area of the amplified fingerprint data, obtain a difference between a capacitance value corresponding to a fingerprint ridge point and a capacitance value corresponding to a fingerprint valley point adjacent to the fingerprint ridge point; determine the designated area as an abnormal area when the difference between the capacitance value corresponding to the fingerprint ridge point and the capacitance value corresponding to the fingerprint valley point adjacent to the fingerprint ridge point is greater than a preset difference threshold; and replace the capacitance value corresponding to the fingerprint ridge point and the capacitance value corresponding to the fingerprint valley point adjacent to the fingerprint ridge point with a median of capacitance values corresponding to pixels in the abnormal area, when the difference between the capacitance value corresponding to the fingerprint ridge point and the capacitance value corresponding to the fingerprint valley point adjacent to the fingerprint ridge point is greater than the difference threshold, to fill an abnormal fingerprint area completely to repair the amplified fingerprint data.
