Abstract

The invention provides a calibration method and device of a fingerprint module and a readable storage medium, and belongs to the field of electronic technologies. The method comprises that when the fingerprint module of a terminal is calibrated and a memory space of the terminal does not include reference calibration information of the fingerprint module, a storage path of a hardware storage spacecorresponding to the fingerprint module is determined; according to the storage path, the reference calibration information which is backup of the reference calibration information of the memory space is read from the hardware storage space; and according to the reference calibration information, the fingerprint module is calibrated. The terminal can carry out calibration on the basis of the backup reference calibration information in the hardware storage space when the memory space does not include the reference calibration information, the data reliability of the hardware storage space is higher, and the calibration reliability of the fingerprint module is improved.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular to a fingerprint module calibration method, device and readable storage medium. Background technique [0002] With the development of electronic technology, fingerprint modules with fingerprint recognition functions are installed in many terminals. When users need to unlock the terminal screen or perform payment transactions, they can touch the fingerprint module with their fingers instead of unlocking the terminal screen or payment transactions. process of entering the password. However, the fingerprint module is often interfered by other accessories or environmental factors in the terminal during production and use, thereby reducing the accuracy of fingerprint identification. For example, during the production process, when the fingerprint module is attached to the glass, air bubbles may be generated between the fingerprint module and the glass, thereby introducing i...
