Problems solved by technology

[0003] The fingerprint recognition and matching effect of existing devices cannot reach the ideal state, and the performance of the fingerprint matching algorithm mainly depends on the number, position and reliability of the extracted feature points
At present, although there are many fingerprint matching algorithms that combine local features and global features, the effect that can be achieved is not very ideal.
Moreover, some people are born with fewer fingerprint features, and it is difficult to collect images. At the same time, the surrounding environment, fingers, temperature and humidity, cleanliness and skin damage will affect the fingerprint recognition effect
