步骤 1
With user’s face closing to the screen, the proximity sensor starts the recognition process. The flood illuminater helps the TrueDepth camera system determine how much illumination will be needed for face recognition. The dot projector projects over 30,000 dots in a known pattern onto the user’s face. Those dots are then photographed by infrared camera for analysis.
How Does Face ID Work
  • With user’s face closing to the screen, the proximity sensor starts the recognition process. The flood illuminater helps the TrueDepth camera system determine how much illumination will be needed for face recognition.

  • The dot projector projects over 30,000 dots in a known pattern onto the user’s face. Those dots are then photographed by infrared camera for analysis.

  • A 3D map of user’s face are then completed. The 3D model is then compared against the stored template. The phone authenticates the identity and unlocks or authorizes a payment.

当手机正面靠近人脸时,距离传感器开始识别。泛光感模块辅助成像系统确定点阵投影仪红外光的强度。

接着,点阵投影仪开始向人脸发出多达3万个点状红外线。

之后红外线摄像机开始捕捉从人脸反射回来的扫描点,从而获得人脸的3D图像。跟系统储存的3D图像进行比对后,完成手机解锁以及其他功能。
