AS608 optical fingerprint module
1. Fingerprint features
The features extracted by the fingerprint algorithm from the acquired fingerprint image represent fingerprint information. Fingerprint storage, comparison and search are all done by operating fingerprint features.
2. Fingerprint processing includes two processes: fingerprint login process and fingerprint matching process [where fingerprint matching is divided into two ways: fingerprint comparison (1:1) and fingerprint search (1:N)].
When fingerprints are registered, each fingerprint is entered twice, the images entered twice are processed, and the synthesized template is stored in the module.
During fingerprint matching, the fingerprint sensor is used to input the fingerprint image to be verified and processed, and then compared with the fingerprint template in the module (if it matches with a template specified in the module, it is called the fingerprint comparison method, which is 1:1 Mode; if matching with multiple templates, it is called fingerprint search mode (ie 1:N mode), the module gives the matching result (pass or fail).
