Iris living body detection method based on infrared lamp flickering

The invention provides an iris living body detection method based on infrared lamp flickering. Living body detection is carried out through an infrared lamp and a camera of the iris recognition equipment; the iris recognition device is provided with a camera and two infrared lamps, the two infrared lamps are symmetrically arranged on the left side and the right side of the camera, and the iris living body detection method based on infrared lamp flickering comprises the steps: S1, randomly selecting a set of flickering rules from a flickering rule base; s2, controlling an infrared lamp of irisrecognition equipment according to the flickering rule in the step S1, and collecting a living body feature code of a current iris recognition object; and S3, calculating living body detection scoresof the two according to the living body feature codes in the step S2 and the Hamming distance of the living body feature template corresponding to the flicker rule in the step S1. 本发明提供了一种基于红外灯闪烁的虹膜活体检测方法，通过虹膜识别设备的红外灯和摄像头进行活体检
