Problems solved by technology

Since the quality of the image is difficult to accurately define with a number, we will use the recorded fingerprints for fingerprint recognition. If it can be recognized normally, the image quality is considered to be qualified; otherwise, the image quality is poor, and the fingerprint module is not valid. Good product
[0003] However, the fingerprint identification function of the operating system of the existing mobile terminal has a lot of steps in the fingerprint entry and identification for safety.
For example, the fingerprint management of the Android system must first enable the password to be unlocked, and the application program APP needs to obtain the legal fingerprint operation authority. The whole process is very complicated and the efficiency is low, so it is not suitable as a test method for the production line.

[0054] Please see figure 1 , the first embodiment of the detection method of the present invention, a detection method for detecting the fingerprint identification function of the mobile terminal fingerprint module, the detection method includes the following steps:

[0055] Step S100, when obtaining the test instruction, control the fingerprint module to start the entry function through the preset service Service for direct acquisition by the application under test; wherein, a service Service for the fingerprint module can be established in advance, the Service The application APP that can be tested can be obtained directly and used to provide a test call interface; thus, the entry function can be started through the Service, and the fingerprint image can be obtained.

[0056] Step S101, obtaining multiple frames of fingerprint images collected continuously. Wherein, the multi-frame fingerprint images can be multiple fingerprint images obtained when one finger is pressed, or...

Abstract

The invention discloses a detection method and detection device. The detection method is used for detecting a fingerprint recognition function of a fingerprint module of a mobile terminal, and comprises the steps of when a test instruction is obtained, controlling the fingerprint module to start an entry function through preset service used for being directly obtained by a tested application; obtaining multiple frames of fingerprint images which are continuously collected; comparing the multiple frames of fingerprint images with each other, and judging whether mutual recognition is successful or not; if mutual recognition is successful, determining that the fingerprint recognition function of the fingerprint module is normal; or, determining that the fingerprint recognition function of the fingerprint module is abnormal. The detection method and detection device have the advantages of improving detection efficiency and being applicable to production line tests.

Description

technical field [0001] The invention relates to the field of fingerprint identification, in particular to a detection method and a detection device. Background technique [0002] At present, the fingerprint module needs to be tested when it is put on the machine, so as to avoid the installation of defective products on the mobile terminal. Before the fingerprint module is assembled on the production line, in addition to the conduction test of the hardware, it is also necessary to evaluate the quality of the collected images, which requires the ability to obtain the fingerprint entry status. Since the quality of the image is difficult to accurately define with a number, we will use the recorded fingerprints for fingerprint recognition. If it can be recognized normally, the image quality is considered to be qualified; otherwise, the image quality is poor, and the fingerprint module is not valid. Good product. [0003] However, the fingerprint identification function of the o...
