Abstract: The present invention provides a multi-camera multi-face video continuous acquisition device. The device comprises: multiple cameras for continuously acquiring a video or image with a face; at least one splicing server for performing face tracking, facial recognition, face cutting, face sorting, and face splicing on the face video or image acquired by the camera; and at least one time synchronizer for calibrating the time of the camera and the splicing server. The devices are interconnected by a network so as to achieve data interaction therebetween. According to the present invention, a face sequence in a longer period of time can be formed by performing sequential splicing on the face image of the same person acquired by multiple cameras. Feature information can be further extracted subsequently from the face sequence sorted by the time sequence for different sequential analyses. The longer the time length of the face sequences is, the more effective information can be extracted after the sequential analyses.
