Fingerprint lock control method

A fingerprint lock control method belongs to the field of fingerprint lock control, and comprises the following steps: acquiring successfully identified fingerprint data, storing the successfully identified fingerprint data, classifying and storing feature information into different groups in a feature matching information library according to different feature positions, and performing information grade division on the feature information; and determining the sample number of the contained feature information, performing gradient descent sorting according to the sample number of the information level, setting a corresponding identification score based on a gradient convergence direction, calculating the identification score, and determining the credibility corresponding to each historical identification sample in the historical identification sample library. The problem of how to select a more effective sample as the identification basis of the fingerprint lock is solved. 一种指纹锁控制方法，所述方法属于指纹锁控制领域，所述方法包括：获取成功识
