Step 202: and matching the third image with a pre-stored unlocking image under the condition that the third image comprises at least one first target area.
The first target region is a region in which the luminance value of the region is greater than a preset second luminance threshold.
When the third image comprises at least one first target area, it is indicated that a strong light area exists in the third image, which indicates that strong light interference exists in the process of acquiring the third image by the user using the infrared camera.
The pre-stored unlocking image may be a face image of the user or a human eye image of the user, which is not limited in the present invention.
After the user presets an unlocking image (such as a face image) and the like, a corresponding unlocking mode is displayed when the user logs in a designated application program or a system interface, for example, after the user sets a face recognition image for a payment application program, a selection item of 'face verification' or 'face brushing login' is displayed when a subsequent user logs in the payment application program.
After a third image acquired by the infrared camera is acquired, when the third image comprises at least one first target area, the fact that a highlight area exists in the third image is indicated, matching of the third image and a prestored unlocking image is executed, and when matching is successful, unlocking is successful, a corresponding application program is directly accessed or a system interface is logged in, and the like.

The first current is safe for human eyes. A person skilled in the art may set the specific value of the first current according to practical situations, and the embodiment of the present invention is not limited thereto. The first image is an image collected by the infrared camera in the unlocking process of the infrared camera, and can be a human face image, a human eye image and the like.
When the terminal unlocking operation input by the user is performed by the infrared camera, the light supplement lamp can be started through the first current which is safer for the human eyes of the user under the condition that no strong light interference exists, so that the first image collected by the infrared camera is obtained.
After a preferred embodiment of the present invention, after the step 201, the method may further include:

In the embodiment of the present invention, when the third image does not include the first target region, indicating that there is no strong light interference, the first current may be turned on to turn on the fill light.
After the first current is applied to turn on the fill light, step 205 is performed.
Step 205: and judging whether a second target area exists in the first image.
The second target area is an area in which a difference between the brightness value of the area in the first image and the brightness value of the other area in the first image is larger than a set difference.
In practical applications, a person skilled in the art may set the specific value of the set difference according to actual needs, and the embodiment of the present invention is not limited thereto.
If the second target area does not exist in the first image, i.e. the lamp shade does not fail, step 207 is executed, and if the second target area exists in the first image, step 206 is executed.
Step 206: determining that the lamp shade is failed.
Under the condition that the second target area exists in the first image, the lamp shade can be determined to be invalid, and prompt information for overhauling the lamp shade can be sent to a user to prompt the user that the lamp shade fails and the lamp shade is overhauled in time.
Step 207: and increasing the starting current of the light supplement lamp from the first current to a second current, and acquiring a second image acquired by the infrared camera.
Under the condition that the lampshade is determined not to be invalid, the current for opening the light supplement lamp can be increased to the second current from the first current, and then when the infrared camera collects images, high-quality images can be collected.
In a specific implementation, the magnitude of the second current may be set according to actual needs, which is not limited in the embodiment of the present invention.
The second image is a high-quality image collected by the infrared camera in the unlocking process of the infrared camera, and can be a human face image, a human eye image and the like.
After the turn-on current of the fill light is increased from the first current to the second current, the second current may be switched on and a second image acquired by the infrared camera may be acquired, and step 208 is performed.
Step 208: and matching the second image with a pre-stored unlocking image.
After the second image is acquired, the second image can be matched with a pre-stored unlocking image, and when the second image is successfully matched with the pre-stored unlocking image, the unlocking is successful, and the second image can be directly logged in a system interface or a corresponding application program interface.
When the matching fails, step 209 is performed.
Step 209: and judging whether the brightness value of the second image is lower than the first brightness threshold value.
When the second image fails to be matched with the pre-stored unlocking image, the light supplement lamp may be in a problem, and the current unlocking user may not be the user with the pre-stored unlocking image.
The first brightness threshold is a preset brightness threshold, and the size of the first brightness threshold is related to factors such as the current used for turning on the fill light, the resolution of the infrared camera, and the like.
Under the condition that the brightness value of the second image is not lower than the first brightness threshold, it can be determined that the fill-in light is not failed, and the reason for the failed matching may be that the collected second image of the current unlocking user is not a pre-stored unlocking image, or may be caused by other reasons, such as dark current light, and the like, and prompt information of re-unlocking or replacing the unlocking mode can be sent to the user to prompt the user to re-unlock, or replace other unlocking modes to unlock.
The brightness value of the second image may be compared with the first brightness threshold, and when the brightness value of the second image is greater than or equal to the first brightness threshold, it indicates that the fill-in lamp is not failed, that is, the fill-in lamp is not failed, step 210 is executed.
When the brightness value of the second image is lower than the first brightness threshold, step 210 is performed.
Step 210: and determining that the supplementary lighting lamp is invalid.
When the brightness value of the second image is lower than the first brightness threshold, the supplementary lighting lamp is failed, that is, the supplementary lighting lamp fails.
Under the condition that the light supplement lamp is determined to be invalid, prompt information of the light supplement lamp being invalid can be sent to a user to prompt the user that the light supplement lamp is invalid, and the user can timely overhaul the light supplement lamp.
