[0047] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0048] Such as figure 1 Shown, on the one hand, the present invention provides a kind of living body detection method based on RGB and IR binocular camera, comprises the following steps:
[0049] Step 1, obtain two sets of video streams through the RGB camera and the IR camera respectively;
[0050] Step 2, performing face detection and living body judgment on the video frames in the two groups of video streams respectively;
[0051] For the video stream obtained by the RGB camera, first extract the video frame, and use the MTCNN algorithm to detect the face of the current video frame in the video stream; then, for the detected face area, extract the joint color texture information to represent the local part of th...
