Method and system for detecting thickness of fingerprint sensor protection layer

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fingerprint sensor detection technology, and more particularly, to a fingerprint sensor protection layer thickness detection method and system. The method for detecting the thickness of the fingerprint sensor protective layer may include the steps of: (a) collecting fingerprint data through the fingerprint sensor; (B) calculating a derivative of the fingerprint data, normalizing a derivative of the fingerprint data, and calculating an integral of the fingerprint sensor according to a derivative of the normalized fingerprint data; Step (c): calculating and obtaining a protective layer thickness of the fingerprint sensor according to the fingerprint sensor integration.
