Abstract
A method and related terminal device for biometric recognition are provided. The method includes: detecting a target distance between a terminal device and a human face through a distance sensor; capturing an iris image through an iris camera and performing iris recognition based on the iris image, when the target distance falls within an iris recognition distance range; capturing a human face image through a front camera and performing face recognition based on the human face image, when the target distance falls within a human face recognition distance range.
Claims17
A terminal device, comprising:
- a distance sensor configured to detect a target distance between the terminal device and a human face;
- an iris camera coupled to the distance sensor and configured to capture an iris image when the target distance falls within an iris recognition distance range;
- a front camera coupled to the distance sensor and configured to capture a human face image when the target distance falls within a human face recognition distance range;
- and
- an application processor (AP) coupled to the distance sensor, the iris camera, and the front camera, the AP configured to:
- detect, through the distance sensor, the target distance between the terminal device and the human face;
- detect, through the front camera, an included angle between the terminal device and the human face, when the target distance falls within at least one of the iris recognition distance range and the human face recognition distance range;
- capture an iris image through the iris camera and implement a secure authentication by performing an iris recognition based on the iris image, when the target distance falls within the iris recognition distance range and the included angle falls within an iris recognition included angle range;
- and
- capture a human face image through the front camera and implement the secure authentication by performing a face recognition based on the human face image when the target distance falls within the human face recognition distance range and the included angle falls within a face recognition included angle range.

- detecting, through a front camera, an included angle between the terminal device and the human face, when the target distance falls within at least one of an iris recognition distance range and a human face recognition distance range;
- capturing an iris image through an iris camera and implementing a secure authentication by performing an iris recognition based on the iris image, when the target distance falls within the iris recognition distance range and the included angle falls within an iris recognition included angle range;
- and
- capturing a human face image through a front camera and implementing a secure authentication by performing a face recognition based on the human face image, when the target distance falls within the human face recognition distance range and the included angle falls within a face recognition included angle range.
A non-transitory computer-readable storage medium storing a computer program which, when executed by a processor, causes the processor to:
- detect a target distance between a terminal device and a human face through a distance sensor;
- detect, through a front camera, an included angle between the terminal device and the human face, when the target distance falls within at least one of an iris recognition distance range and a human face recognition distance range;
- capture an iris image through an iris camera and implement a secure authentication by performing an iris recognition based on the iris image, when the target distance falls within the iris recognition distance range and the included angle falls within an iris recognition included angle range;
- and
- capture a human face image through the front camera and implement a secure authentication by performing a face recognition based on the human face image, when the target distance falls within the human face recognition distance range and the included angle falls within a face recognition included angle range.
