The inventor finds that the face access control machine with the face skin grinding function generally has the problem of low detection efficiency at present, mainly because: when the user is far away from the face access control machine, the face is smaller, and if a stronger skin grinding effect is added, a great deal of face details are lost. Secondly, when the brightness of the detection environment is seriously insufficient, if the face skin is further opened, a great amount of face details are lost, and the detection failure is caused by the fact that the score of the face living body detection judgment is low due to the two reasons, so that the detection efficiency is reduced.
Therefore, the invention provides a method for dynamically adjusting the skin-polishing effect, namely, the strength of the face skin-polishing effect is not fixed, and the grade is dynamically adjusted according to the size of the face frame and the ambient brightness, so that the requirements of long-distance and dark-environment face recognition efficiency can be met, and the requirements of customers on the face skin-polishing effect can be met.

Preferably, fig. 2 is a schematic flow chart of dynamic skin grinding based on ambient brightness according to an embodiment of the application, as shown in fig. 2,
According to the change of the current environment brightness, the exposure time of the camera of the face access control camera is preferentially adjusted, so that the exposure value of the camera of the face access control camera is equal to a preset exposure value;
And under the condition that the exposure time is regulated to the maximum and the exposure value is not equal to the preset exposure value, adjusting the GAIN value (GAIN value) of the camera of the face access control camera to ensure that the exposure value of the camera of the face access control camera is equal to the preset exposure value, and judging whether to start the face peeling function or not based on the exposure value obtained after adjustment.
Optionally, judging whether to start the face skin grinding function directly based on the adjusted GAIN value (GAIN value), if the GAIN value (GAIN value) is smaller than or equal to a preset GAIN value, the brightness of the current environment meets the preset requirement, and starting the face skin grinding function; if the GAIN value (GAIN value) is larger than the preset GAIN value, the brightness of the current environment does not meet the preset requirement, and the face skin-grinding function is closed
It should be noted that, two factors affecting the exposure value of the camera are exposure time and GAIN value, wherein, the exposure time is adjusted preferentially and the GAIN value is adjusted again, so that the noise of the acquired image is less, further more face details are acquired, and the detection efficiency is improved.
Optionally, if the face access control machine further includes a brightness sensor, in step S102, whether the brightness of the current environment meets the preset requirement can be directly determined by the brightness sensor.

When the skin grinding grade is dynamically adjusted, if the face access control machine detects that the size of a face frame corresponding to the face of the user is smaller than or equal to that of a first face frame, the skin grinding grade is adjusted to be the first skin grinding grade; if the face access control machine detects that the size of the face frame corresponding to the face of the user is between the first face frame and the second face frame, the skin grinding grade is adjusted to be the second skin grinding grade; and if the face access control machine detects that the size of the face frame corresponding to the face of the user is larger than that of the second face frame, adjusting the skin grinding grade to be a third skin grinding grade.
Optionally, if the face access control machine further comprises a distance sensor, in step S104, under the condition of opening the face skin polishing function, the distance between the user and the face access control machine is identified by the distance sensor, the skin polishing level is dynamically adjusted according to the distance,

The brightness judging module is used for acquiring the exposure value of the camera of the face access control camera in real time; if the exposure value is equal to the preset exposure value, the brightness of the current environment meets the preset requirement, and the face skin grinding function is started; if the exposure value is not equal to the preset exposure value, the brightness of the current environment does not meet the preset requirement, and the face peeling function is closed;
the distance judging module is used for verifying the face of the user in real time through the face access control machine under the condition of starting the face peeling function, and dynamically adjusting the peeling level according to the size of the face frame corresponding to the face of the user until the user passes the real-time verification.
8. An electronic device comprising a memory and a processor, wherein the memory has stored therein a computer program, the processor being arranged to run the computer program to perform the dynamic skin-based face detection method of any one of claims 1 to 6.
9. A computer-readable storage medium, on which a computer program is stored, characterized in that the program, when being executed by a processor, implements a dynamic skin-based face detection method as claimed in any one of claims 1 to 6.
