A human shape or face detection algorithm belongs to a mature algorithm, and mainly carries out human shape or face detection by extracting human shape or face characteristics of an image.
Step 203: the client module encodes the image collected by the camera and then sends the encoded image to the monitoring server in real time, and meanwhile, if the human figure or the human face is detected in the image, the corresponding relation between the image coordinates of the human figure or the human face and the image frame number is sent to the monitoring server.

Step 206: and for the image coordinates of each human figure or face, the monitoring server determines the position of the human figure or face in the image according to the image coordinates of the human figure or face, performs amplification processing on the human figure or face according to a set amplification algorithm, sends the image containing the amplified human figure or face to a local display terminal for display, and the process is finished.
Specifically, if the image coordinates of a plurality of human figures or human faces are found according to the frame number of the image, that is, the frame image has a plurality of human figures or human faces, then: copying the image for many times according to the number of the human figures or the human faces to obtain a plurality of copied images, sequentially selecting the image coordinates of one human figure or the human face from the image coordinates of all the human figures or the human faces, then sequentially selecting one copied image from the plurality of copied images, determining the position of the human figure or the human face in the selected image according to the selected image coordinates of the human figure or the human face, amplifying the human figure or the human face in the selected image according to a set amplification algorithm, and finally respectively obtaining the amplified human figure or the human face image containing the human figure or the human face for each human figure or the human face. I.e. finally, each image contains an enlarged human figure or face, respectively.
The monitoring server may first send the original image (i.e. the image without human figure or human face being enlarged) to the local display terminal for displaying, when it is detected that one of the human figures or human faces has an access request, for example: and after the user clicks one of the human figures or the human faces, sending the amplified human figure or human face image containing the human figure or the human face to a local display terminal for displaying.
In addition, when it is detected that there is an access request for a human figure or face on the main window image, for example: when a user clicks one human figure or face on the main window image, the monitoring server sends the floating window image containing the amplified human figure or face of the human figure or face to the local display terminal, the local display terminal displays the image in front of the main window in the form of a floating window, and when the floating window image is detected to have an access request, for example: and when the user clicks the floating window image, the monitoring server converts the floating window image into a main window image and displays the main window image on the local display terminal.
