Abstract: The present invention discloses a system integrating video communication and physical sign analysis, comprising at least one front-end device. The front-end device comprises a camera device, a display device, an audio device, a button device and a processor. The camera device, the display device, the audio device and the button device are all connected to the processor, and the processor can connect to the Internet network and the mobile device via wired or wireless means. The front-end device and the mobile device can perform video communication, and the front-end device can perform physical sign analysis according to the images collected by the camera device. Based on some applications in the prior art, the present invention combines video collection technology and human face analysis technology to perform physical sign analysis and obtain related indexes.

Abstract: The present invention discloses a multi-camera multi-face video splicing acquisition device, comprising a plurality of cameras for successively capturing video or images with faces, at least one splicing server for face tracking, face recognition, face cutting, face sorting and face splicing of face videos or images captured by cameras; and at least one time synchronizer for calibrating the time of at least one camera and splicing server; the above devices are interconnected through a network to achieve data interaction with each other. By serially splicing the face images of the same person acquired by multiple cameras, a face sequence of a longer period of time can be formed, and the face sequences sorted by time series could be used to further extract feature information for various time series analysis, and the longer the length of time of the face sequence, the more valid information can be extracted after time-series analysis.
