Fingerprint registration method and device

A fingerprint registration device, comprising:

• a memory, a processor, and a program stored in the memory and executable by the processor, wherein the processor is configured to perform the fingerprint registration method and the method comprises:
• obtaining a fingerprint to be registered and a target fingerprint;
• extracting features from the fingerprint to be registered and the target fingerprint to obtain a first fingerprint feature of the fingerprint to be registered and a second fingerprint feature of the target fingerprint, wherein the first fingerprint feature comprises a first ridge feature and a first phase feature;
• the second fingerprint feature comprises a second ridge feature and a second phase feature;
• performing a initial registration on the fingerprint to be registered and the target fingerprint according to the first ridge feature and the second ridge feature to obtain a initial registration result;
• obtaining phase difference information of a phase overlap region between the first phase feature and the second phase feature;
• and
• adjusting the initial registration result according to the phase difference information to obtain a final registration result of the fingerprint to be registered and the target fingerprint.

A non-transitory computer readable storage medium, configured to store executable program codes, wherein the executable program codes are configured to execute the fingerprint registration method and the method comprises:

• obtaining a fingerprint to be registered and a target fingerprint;
• extracting features from the fingerprint to be registered and the target fingerprint to obtain a first fingerprint feature of the fingerprint to be registered and a second fingerprint feature of the target fingerprint, wherein the first fingerprint feature comprises a first ridge feature and a first phase feature;
• the second fingerprint feature comprises a second ridge feature and a second phase feature;
• performing a initial registration on the fingerprint to be registered and the target fingerprint according to the first ridge feature and the second ridge feature to obtain a initial registration result;
• obtaining phase difference information of a phase overlap region between the first phase feature and the second phase feature;
• and
• adjusting the initial registration result according to the phase difference information to obtain a final registration result of the fingerprint to be registered and the target fingerprint.
