The face snapshot machine integrates video monitoring and video recording functions of a traditional monitoring camera, and meanwhile has the function of accurately pushing face pictures and background pictures in a monitoring range to a background, so that the effectiveness of a user for acquiring data is facilitated. When video content needs to be backtracked, effective information can be obtained by checking the pushed picture first, and the content needing to be checked can be quickly positioned.

At present, the mode of pushing the image to the background by the face snapshot machine can be divided into optimal image pushing and timing image pushing. The mechanism of optimal mapping is as follows: when a face appears to disappear in the whole process of the shooting range of the snapshot machine, an algorithm judges a picture with the optimal quality, and the picture is pushed out when the face tracking is interrupted. The optimal image pushing mechanism is suitable for application scenes that the human face does not stay too long in the visual field of the snapshot machine.

If tracking exists all the time when a face appears in the visual field range of the snapshot machine for a long time, only one pushed face image can be obtained finally under the optimal image pushing mechanism, and the states of the face from appearance to disappearance cannot be reflected well. In order to solve the problem, the face snapshot machine is provided with a timing image pushing mode. The mechanism of timing graph push is as follows: the timing map-pushing mode has 2 parameters to be set: the map-pushing time interval T and the total number N of the map-pushing (the settable range of N is 2-100). When a human face enters the visual field range of the snapshot machine, the human face snapshot machine starts to push the image. The image pushing mode is that every time T, one face image shot at the moment is pushed, and N-1 images are pushed in total; and then, when the tracking of the face is interrupted, pushing the last picture. If the tracking is interrupted when the N-1 pictures are not pushed completely, a picture judged to have the best quality by an algorithm is pushed again. In practical applications, when the face capture machine pushes a picture to a background, errors may occur, for example, the number of pushed pictures is smaller than an expected value within a preset time, and therefore the face capture machine needs to be tested.
