Iris living body detection method based on infrared lamp flickering

The invention provides an iris living body detection method based on infrared lamp flickering. The iris living body detection method based on infrared lamp flickering comprises the following steps: S1, establishing a flickering rule base; s2, collecting a first active feature vector of a positive sample and a second active feature vector of a negative sample according to a flicker rule in a flicker rule base, taking the first active feature vector and the second active feature vector as training samples of the flicker rule, and training the training samples through a machine learning algorithmto obtain a classification model; s3, selecting a flicker rule in a flicker rule base, and collecting a third active feature vector of the current iris recognition object when the infrared lamp flickers according to the flicker rule; and S4, enabling the classification model to predict whether the iris recognition object is a living body or not according to the third active feature vector. 本发明提供了一种基于红外灯闪烁的虹膜活体检测方法，所述基于红外
