Unlocking control method and related products

An unlocking control method, comprising:

• acquiring an environmental parameter;
• acquiring first biometric information;
• determining a first biometric control parameter and a second biometric control parameter corresponding to the environmental parameter;
• performing a first biometric recognition on the first biometric information according to the first biometric control parameter, and acquiring a matching value corresponding to the first biometric information;
• adjusting the second biometric control parameter according to the matching value;
• acquiring second biometric information when the first biometric recognition is passed;
• performing a second biometric recognition on the second biometric information, according to the adjusted second biometric control parameter;
• and
• performing a next unlocking process when the second biometric recognition is passed.

An electronic device, comprising an application processor, a memory and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the application processor, the one or more programs comprises instructions to perform an unlocking control method, the method comprises:

• acquiring an environmental parameter;
• acquiring first biometric information, wherein the first biometric information is an image;
• performing image quality evaluation on the first biometric information, and obtaining an image quality evaluation value, wherein the first biometric information is evaluated by more than one image quality evaluation index, and the more than one image quality evaluation indexes each correspond to a weight;
• performing, in response to the image quality evaluation value being lower than a preset quality threshold, image enhancement processing on the first biometric information to thereby acquire enhanced first biometric information;
• determining a first biometric control parameter and a second biometric control parameter corresponding to the environmental parameter;
• performing a first biometric recognition on the enhanced first biometric information according to the first biometric control parameter;
• acquiring second biometric information when the first biometric information is recognized;
• performing a second biometric recognition on the second biometric information, according to the second biometric control parameter;
• and
• performing an unlocking process when the second biometric information is recognized.
