The more sub- equipment of spectrogram, obtains respectively sub- equipment with spectrogram and IP unpacks equipment and is connected, for spectrogram to be obtained into sub- equipment
The positive local binary patterns feature spectrogram for obtaining is matched respectively with the positive local binary patterns feature spectrogram of each benchmark, will be composed
Figure obtains the negative local binary patterns feature spectrogram of sub- equipment acquisition and bears local binary patterns feature spectrogram with each benchmark respectively
Matched, all the match is successful and the corresponding authorized user's title of the positive local binary patterns feature spectrogram of benchmark that matches for the two
When identical with the corresponding authorized user's title of the negative local binary patterns feature spectrogram of the benchmark for matching, then export recognition of face into
Function signal and authorized user's title corresponding with the positive local binary patterns feature spectrogram of the benchmark for matching, will otherwise export people
Face recognition failures signal；
IP unpacks equipment, for being connected with long-range data server network, is received at data server by network
IP packets, and IP packets are unpacked to obtain 6LowPAN packets；Wherein, IP packets are that 6LowPAN packets are entered
Row beats the packet obtained after IP bags, and the load in 6LowPAN packets includes the positive office of each benchmark at data server
Portion's binary pattern feature spectrogram and the negative local binary patterns feature spectrogram of each benchmark, the head in 6LowPAN packets is pressure
Contracting data, the head in 6LowPAN packets after decompression is used to parse the load in 6LowPAN packets；Wherein,
The positive local binary patterns feature spectrogram of each benchmark is to carry out positive local two in advance to corresponding authorized user's benchmark face-image
The image that value pattern feature spectrogram is extracted and obtained, the negative local binary patterns feature spectrogram of each benchmark is that corresponding mandate is used
Family benchmark face-image carries out in advance the image that negative local binary patterns feature spectrogram is extracted and obtained；
Edge sensing equipment, unpacks equipment and is connected with IP, for receiving the 6LowPAN packets that IP unpacks equipment output, obtains
The head of the 6LowPAN packets of compressed data is rendered as, after decompressing the head of 6LowPAN packets to be decompressed
Head in 6LowPAN packets；
6LowPAN unpacks equipment, is connected with edge sensing equipment, for receiving 6LowPAN packets to obtain 6LowPAN data
Load in bag, and the load in 6LowPAN packets is solved based on the head in the 6LowPAN packets after decompression
Analysis, to obtain the positive local binary patterns feature spectrogram of each benchmark and the negative local binary patterns feature spectrogram of each benchmark.
