Abstract

The present application discloses a method, apparatus and system for measuring finger dryness and wetness. Measurement methods include: obtaining a fingerprint image; obtaining a fingerprint signal intensity and an image background intensity according to a fingerprint image; and determining a finger's degree of wetness and dryness according to a fingerprint signal intensity and an image background intensity. The method, the device and the system for measuring finger dryness and wetness provided by the present invention obtain the fingerprints by acquiring the fingerprints and obtaining the fingerprinting signal intensity and the image background intensity according to the fingerprints image by analyzing and determining the fingerprint signal intensity and the image background intensity wet degree effectively overcomes the defect that the traditional technology is susceptible to image background fluctuation, noise and the like and has low accuracy due to the analysis and comparison of images, thereby ensuring the accuracy and reliability of finger dryness and wetness measurement. In addition, Through the accurate measurement of finger dryness is conducive to fingerprint acquisition technology improvements and optimization.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a method, device and system for measuring the dryness and wetness of fingers. Background technique [0002] With the continuous advancement of science and technology, fingerprint recognition technology is becoming more and more mature, and its application fields are becoming more and more extensive. Unlocking and medical fields, etc. In the medical field, the dryness and wetness of fingers can reflect the health information of the human body. Therefore, measuring the dryness and wetness of fingers can provide reference data for medical diagnosis. [0003] The traditional fingerprint collection technology usually does not consider the degree of dryness and wetness of the finger. Generally, the user's fingerprint is collected directly. At this time, when the user's finger is too dry or too wet, the collected fingerprint image is likely to be unclear , thereby af...
