In an embodiment, the specific implementation manner of the terminal device acquiring the fingerprint image through the fingerprint identification area in step S101 is as follows: an induction electrode of a fingerprint identification module of terminal equipment acquires a normal bottom layer data set and an abnormal bottom layer data set, wherein the normal bottom layer data set comprises a plurality of normal bottom layer data values, and the abnormal bottom layer data set comprises a plurality of abnormal bottom layer data values; the terminal equipment determines a target bottom layer data set corresponding to the abnormal bottom layer data set according to the normal bottom layer data set; and the terminal equipment generates a fingerprint image according to the normal bottom layer data set and the target bottom layer data set.
Further, in the above example process, an example implementation process of determining, by the terminal device, the target underlying data set corresponding to the abnormal underlying data set according to the normal underlying data set is as follows:
the terminal equipment determines an average value according to a plurality of normal bottom layer data values contained in the normal bottom layer data set; and the terminal equipment changes all the abnormal bottom layer data contained in the abnormal bottom layer data set into the average value so as to obtain the target bottom layer data set.
Or, the example implementation process of the terminal device determining the target underlying data set corresponding to the abnormal underlying data set according to the normal underlying data set is as follows:
the terminal equipment acquires a normal bottom layer data value with the minimum data value from a plurality of normal bottom layer data values contained in the normal bottom layer data set; and the terminal equipment changes all the abnormal bottom layer data contained in the abnormal bottom layer data set into the normal bottom layer data value with the minimum data value so as to obtain the target bottom layer data set.
Or, the example implementation process of the terminal device determining the target underlying data set corresponding to the abnormal underlying data set according to the normal underlying data set is as follows:
the terminal equipment acquires any one normal bottom layer data value from a plurality of normal bottom layer data values contained in the normal bottom layer data set; and the terminal equipment changes all the abnormal bottom layer data contained in the abnormal bottom layer data set into any one normal bottom layer data value so as to obtain the target bottom layer data set.

The induction electrode of fingerprint identification module includes a plurality of normal induction electrodes and a plurality of unusual induction electrode, and wherein, unusual induction electrode appears in unusual induction electrode. And acquiring a normal bottom layer data set through the plurality of normal induction electrodes, and acquiring an abnormal bottom layer data set through the plurality of abnormal induction electrodes.
S102, when the fingerprint image is incorrect, the terminal equipment acquires the touch data detected by the touch sensor.
In one embodiment, the method of fig. 1 further comprises:
the terminal equipment compares and matches the fingerprint image with M prestored fingerprint templates, wherein M is a positive integer; if the fingerprint image is matched with one of the plurality of pre-stored fingerprint templates, the fingerprint image is correct, and if the fingerprint image is not matched with any one of the plurality of pre-stored fingerprint templates, the fingerprint image is incorrect.
Further, the M fingerprint templates are M fingerprint templates with the highest matching priority among N pre-stored fingerprint templates, and N is greater than M.
Further, the matching priority of the fingerprint template may be user-defined; or the terminal device is determined based on the usage parameters of the fingerprint template (e.g., the number of times of successful matching within a certain period of time), for example, the matching priority of the fingerprint template is determined based on the number of times of successful matching within a certain period of time, and the higher the number of times of successful matching within a certain period of time is, the higher the matching priority of the fingerprint template is.
Among them, the touch sensor includes a one-touch type sensor and a wipe type sensor. The touch sensor is a touch switch module manufactured based on the principle of capacitance induction. The gold plated contact surface of the human body or metal touch sensor is sensed. In addition to direct touch with a metal surface, contact through a certain thickness of plastic, glass or other material can also be sensed, and the sensing sensitivity depends on the size of the contact surface and the thickness of the covering material.
In one embodiment, the touch data is detected by the touch sensor while the fingerprint image is captured by the fingerprint identification area; alternatively, the touch data is detected by the touch sensor after the terminal device determines that the fingerprint image is incorrect.
In another embodiment, the touch data may also be detected by the touch sensor in other time periods, for example, the touch data is detected by the touch sensor in the process of identifying whether the fingerprint image is correct or not by a terminal device, or the touch data is detected by the touch sensor in the process of acquiring the fingerprint image by the fingerprint identification area, and so on.
In an embodiment, the number of the touch sensors is N, the touch data is detected by M touch sensors in a designated area of the touch screen, N is greater than M, and both N and M are integers greater than 1.

S103, when the sensing data meet the touch operation judgment condition, the terminal equipment maintains the current times of error identification.
Specifically, assuming that the current number of times of erroneous recognition is 3 times, after step S103 is executed, the number of times of erroneous recognition is still 3 times. The number of times of error identification refers to the number of times that the fingerprint image acquired by the fingerprint identification area is identified as an error fingerprint image by the terminal equipment.
When the touch screen is not touched, the sensor data acquired by the sensing sensor arranged below the touch screen is zero, and the touch operation judgment condition is not met. When the touch screen is touched, the sensor data acquired by the sensing sensor arranged below the touch screen is not zero, and the touch operation judgment condition is met.
In one embodiment, the method of fig. 1 further comprises:
and when the sensing data do not accord with the touch operation judgment condition, updating the number of times of error identification, wherein the updated number of times of error identification is equal to the number of times of current error identification plus 1.
Specifically, under normal conditions, if a user wants to perform a fingerprint unlocking operation, the user will clearly place an unlocking finger on the fingerprint identification area because the purpose is clear, as shown in fig. 8. In this case, the touch screen of the terminal device does not normally detect a touch operation. However, if the user touches the fingerprint identification area by holding the hand of the terminal device with his hand carelessly, as shown in fig. 9, in this case, it is highly possible that the user touches the touch screen while touching the fingerprint identification area, in this case, in order to avoid the problem that the user cannot use the fingerprint unlocking function because the non-user finger touches the fingerprint identification area, the terminal device needs to determine whether the sensing data acquired by the touch sensor at this time meets the touch operation determination condition, if so, it is highly possible that the non-user finger touches the fingerprint identification area, in this case, the terminal device does not update the number of times of erroneous identification, and only needs to maintain the current number of times of erroneous identification, thereby improving the user experience.
