Abstract:
A method and a related terminal device for fingerprint template update include the follows. A target fingerprint image that is successfully matched is obtained, and the target fingerprint image is assessed. When the result of assessing the target fingerprint image meets a fingerprint template update condition, a fingerprint template that matches with the target fingerprint image is updated according to the target fingerprint image.

Claim (Index 1):
A method for updating fingerprint template, comprising:\n obtaining a target fingerprint image that is successfully matched; assessing feature points and image quality of the target fingerprint image; updating a first target fingerprint template according to the target fingerprint image, when a result of assessing the feature points and the image quality meets a fingerprint template update condition, the first target fingerprint template being a fingerprint template that matches with the target fingerprint image; and before the updating a first target fingerprint template according to the target fingerprint image, determining, by a terminal device, whether a number of fingerprint templates pre-stored in the terminal device is greater than or equal to a first threshold; when the number of the fingerprint templates pre-stored in the terminal device is greater than or equal to the first threshold, the updating a first target fingerprint template according to the target fingerprint image comprising: determining a coincidence percentage between feature points of the target fingerprint image and feature points of the first target fingerprint template; determining a non-coincidence region of the target fingerprint image and the first target fingerprint template when the coincidence percentage between the feature points of the target fingerprint image and the feature points of the first target fingerprint template is greater than or equal to a second threshold, and updating the first target fingerprint template according to the non-coincidence region; the non-coincidence region comprising a first non-coincidence region of the target fingerprint image with respect to the target fingerprint template and a second non-coincidence region of the first target fingerprint template with respect to the target fingerprint image, the updating the first target fingerprint template according to the non-coincidence region comprising: determining, by the terminal device, a coincidence percentage of feature points of the first non-coincidence region and feature points of the second non-coincidence region; adding, by the terminal device, the first non-coincidence region into the first target fingerprint template when the coincidence percentage of the feature points of the first non-coincidence region and the feature points of the second non-coincidence region is less than or equal to a sixth threshold; adding a non-coincidence region of the first non-coincidence region with respect to the second non-coincidence region into the second non-coincidence region when the coincidence percentage of the feature points of the first non-coincidence region and the feature points of the second non-coincidence region is greater than the sixth threshold and less than or equal to a seventh threshold; and replacing, by the terminal device, the second non-coincidence region with the first non-coincidence region when the coincidence percentage of the feature points of the first non-coincidence region and the feature points of the second non-coincidence region is greater than the seventh threshold and less than or equal to an eighth threshold.
