Fingerprint sensor calibration method and device

The invention discloses a fingerprint sensor calibration method and device. The method comprises: calibrating an fingerprint sensor in an intelligent terminal when monitoring a preset fingerprint sensor calibration event, and storing the calibration data of the calibrated fingerprint sensor; and employing the stored calibration data of the calibrated fingerprint sensor to initialize the fingerprint sensor when a fingerprint sensor initialization event is monitored, and the intelligent terminal stores the calibration data of the fingerprint sensor. In the technical scheme, when a fingerprint sensor initialization event is monitored, and the intelligent terminal stores the calibration data of the fingerprint sensor, the stored calibration data of the fingerprint sensor fingerprint sensor is employed to initialize the fingerprint sensor, thereby avoiding calibrating the fingerprint sensor every time initializing the fingerprint sensor, and improving the initialization speed of the fingerprint sensor.
