Fingerprint base library input method and device, electronic equipment and storage medium

The invention relates to a fingerprint base library input method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining an input fingerprint picture, extracting to-be-input fingerprint features of the input fingerprint picture, judging whether the to-be-input fingerprint feature is similar to any fingerprint feature in an input base library or not, if the to-be-input fingerprint feature is not similar to the fingerprint feature in the input base library, storing the to-be-input fingerprint features in the input base library, and updating an input count n, if the to-be-input fingerprint feature is similar to any fingerprint feature in the input base library, updating an input count n according to the duplicate checking interval, judging whether the current input count n is equal to an input threshold value or not, if the current input count n is equal to the input threshold, ending input of the input base library, and if the current input count n is smaller than the
