[0002] With the rapid development of technologies such as mobile Internet and Internet of Things, biometric technologies are increasingly widely used in the field of identity authentication. Among them, fingerprint recognition, as one of the earliest and most mature biometric technologies, has become an indispensable means of identity verification in many devices and systems due to its unique uniqueness and immutability. A fingerprint recognition system includes key components such as a fingerprint recognition sensor, a feature extraction / matching module, a feature template library, and application software. During the recognition process, fingerprint matching first requires extracting the features of the fingerprint to be verified and comparing them with the template fingerprints in the fingerprint template library to determine whether two fingerprint images come from the same finger. Therefore, the accuracy and integrity of fingerprint collection are crucial for the recognition result.

[0003] The recognition area of a fingerprint recognition sensor is generally set as a planar structure. In actual use, there are often problems such as poor fit with the finger and low comfort. In related technologies, the recognition area of a fingerprint recognition device lacks a finger profiling structure, so that when a user performs fingerprint recognition by pressing with a finger, the finger cannot be guided and limited, affecting the fingerprint recognition efficiency.
