The invention provides a fingerprint identification method with a function of distinguishing the sliding track. The fingerprint identification method comprises the steps of rough processing, specifically, a fingerprint image is subjected to partition and smoothing so as to improve the pixel point identification degree, and binarization processing is conducted; step of feature processing, specifically, feature extraction is conducted on the fingerprint image subjected to rough processing so as to remove fake feature points; step of superposition of energy points, specifically, energy feature points are added into the fingerprint image subjected to feature processing; step of matching, specifically, the fingerprint image subjected to superposition energy point processing is compared with template features, and a preliminary result of fingerprint identification is obtained; and the step of identification of the sliding direction, specifically, through the temperature and the electrical inductance change, fingerprint identification is finally successful only the finger sliding direction and / or track is distinguished to be basically coincident with the preset template. The invention further provides a fingerprint identification sensor and system.
Description
technical field [0001] The invention relates to the technical field of biological identification, in particular to a fingerprint identification method, a sensor and a system with sliding track discrimination. Background technique [0002] In the field of biometrics technology, due to the ease of fingerprint collection and the uniqueness of the lines, it can be conveniently used for identification and matching. Therefore, fingerprint identification technology is widely used in various fields. There are already many types of fingerprint identification sensors or identification devices. Traditional Fingerprint recognition mainly realizes fingerprint recognition through three detection technologies such as photoelectricity, capacitance or ultrasonic. [0003] In the prior art, more efforts are devoted to the research on improving the algorithm or identification method of fingerprint identification, and the anti-counterfeiting technology, such as the identification of artificial ...
