FINGER HUMIDITY MEASURING METHOD, APPARATUS AND SYSTEM

摘要

The present application discloses a method, an apparatus and a system for measuring finger humidity. The measurement method comprises: obtaining a fingerprint image (S101); obtaining a fingerprint signal intensity and an image background intensity according to a fingerprint image (S102); and determining a finger's degree of humidity according to the fingerprint signal intensity and the image background intensity (S103). According to the method, the device and the system for measuring finger humidity provided by the present invention,the fingerprint image is obtained, the fingerprint signal intensity and image background intensity is determined based on the fingerprint image, thereby the fingerprint humidity degree is determined by analyzing and deciding the fingerprint signal intensity and the image background intensity. The invention effectively overcomes the defect that the traditional technology is susceptible to image background fluctuation, noise and the like and has lower accuracy due to the analysis and contrast of images, thereby ensuring the accuracy and reliability of finger humidity measurement. In addition, accurate measurement of the humidity of the finger is conducive to the improvement and optimization of the fingerprint acquisition technology.
