There are three parts to form altogether for frequency monitoring system, as shown in Figure 1, being monitoring camera 101, first processor 102 and second respectively
Processor 103；This method comprises:
Step 1, the video taken is sent to first processor 102 by WIFI by monitoring camera 101；
Step 2, video is divided into continuous multiple video-frequency bands by first processor 102, each video-frequency band when it is 5 points a length of
Clock；
Step 3, first processor 102 extracts the key frame in video-frequency band；
Step 4, first processor 102 extracts first object coding according to the first acquisition modes from key frame；
Step 5, first processor 102 is plucked using first that the first digest algorithm obtained in advance calculates first object coding
It wants；
Step 6, first processor 102 uses the first communication channel, and first is made a summary and is sent to second processor 103；The

The monitoring camera 101 of a small range is connect by way of wifi with first processor 102, in turn, monitoring camera 101
Shooting obtained video can be sent by wifi to first processor 102.
Video is divided into continuous multiple video-frequency bands first after receiving video by first processor 102.Ordinary circumstance
Under, the video that first processor 102 receives is a continuous video, and needs carry out timing while receiving video,
Every timing reaches 5 minutes, and video received in nearest 5 minutes is just formed a video-frequency band.Under normal circumstances, a view
Video in frequency range be shot by the same monitoring camera 101 caused by.
Since video is to be arranged to be formed according to the sequence of time order and function by multiple continuous frame images, then, at first
Manage device 102 can also extract key frame and come out, with the time in subsequent steps from video-frequency band.
There are many modes for extracting key frame, is set forth below two kinds can used as example.The first, the first processing
The A frame image in video-frequency band may be selected as key frame in device 102, and the sum of brightness value of whole pixels of A frame image is higher than view
