Including one or several in gsm module, 3G module, 4G modules, bluetooth module and WIFI module；The wire communication module packet
Include one or two of serial communication module and USB module.I.e. communication module can be gsm module, 3G module, 4G modules,
Bluetooth module, WIFI module, serial communication module or USB module can be serial communication module or combination, the GSM of USB module
The combination of module and 3G module, the combination of 4G modules and WIFI module, the combination of bluetooth module and WIFI module, WIFI module and
Combination of USB module etc., preferred communication module is the combination of WIFI module and USB module herein.
Preferably, the light compensating lamp includes the visible light light compensating lamp being respectively electrically connected with processor and power module and red
Outer light compensating lamp.The processor is also electrically connected with speech horn, and speech horn is electrically connected with power module.
Preferably, the processor is arm processor, or other processors.
The course of work of the present invention is as follows：
1, personnel register：By the prompt of human-computer interaction module, according to infrared camera and visible image capturing head to face
Collection apparatus is carried out, under the control of a processor compiles the face characteristic of extraction by personnel after picture processing chip is handled
Code corresponds and is that form stores in memory.
2, according to requirements, order setting recognition mode is issued by human-computer interaction module：
1) personal identification pattern：Personal identification state, nonrecognition action are constantly in after startup.
2) action recognition pattern：Handle action recognition pattern, nonrecognition personnel identity always after.
3) recognition mode is combined：I.e. recognizable personnel can recognize that personnel's action, output personnel identity coding are carried out with it again
Action coding.
4) expression password identification pattern：First personnel's face similarity identification is passed through, and facial expression is acted and moved
Make that expression password that sequencing also will originally be set with the personnel is consistent to be just identified by.
The identifiable facial expression of face, which acts, includes：It is simple eye closure reach certain time length, magnify mouth reach certain time length,
Discharge tongue reaches certain time length, left and right shakes the head and reaches certain number, left-hand rotation head, right-hand rotation head, come back, bow, smiling, rubbing one's eyes
Eyeball eats, opens eyes wide etc. and setting one-to-one action coding.These face feelings actions may be set to be coerced by danger
When and special command operate when condition adjudgement, carry out the corresponding command subsequent action.
3, light compensating lamp brightness is automatically adjusted after equipment starts, and is worked according to the recognition mode of setting：
1) when personal identification pattern：When detecting face, according to the image of infrared camera and visible image capturing head into
Row handles and completes currently to identify the face characteristic acquisition of personnel, is compared with the characteristic in memory, works as similarity
When reaching the threshold values of setting, judge that personal identification passes through, store and exports personnel's coding by various communication modes；Work as similarity
Less than setting threshold values when, judge that personal identification does not pass through, by various communication modes output identification not by result.
2) when action recognition pattern：When detecting face, according to the image of infrared camera and visible image capturing head into
Row handles and completes currently to identify upper part of the body collection apparatus, is compared with the characteristic of previous image, analyzes changing features
Position and variation tendency are compared according to stored part variation and variation tendency feature in program, when similarity reaches
When the threshold values of setting, exports corresponding action by different communication modes and encode；When threshold values of the similarity less than setting, after
Continuous description image.
3) when combining recognition mode：When detecting face, according to the image of infrared camera and visible image capturing head into
Row handles and completes currently to identify upper part of the body collection apparatus, the other identification of advanced pedestrian, if personnel identity identification does not pass through
Side exports the result of recognition failures.After personnel identity is identified by, action recognition is carried out, action recognition passes through, and exports personnel couple
It should encode and act corresponding coding；Action recognition does not pass through, then exports personnel and correspond to coding.
4) expression password identification pattern：The facial expression action password and action that setting keeper verifies in systems
Sequencing can set 1 facial expression action or be combined as password by the sequence of multiple actions.First to personnel face when identification
Portion's similarity is identified, after similarity passes through, by identification personnel facial expression action and its sequencing whether with original
Setting is consistent, if personnel's face similarity, facial expression act, the sequencing of action is all consistent, is judged as that identification is logical
It crosses, output personnel's coding.When similarity identification, action or action sequencing and former setting are inconsistent, then judge to fail, output
Recognition failures result.
4, when identifying personnel identity, using News Search, mode is as follows：
When human body close to when, infrared camera and visible image capturing head have recognized face Partial Feature, i.e., by memory
It is one group that middle similarity personnel in the top, which encode,；In not stopping near procedure, by certain time length and close to distance length
It is compared several times, forms several groups similarity personnel in the top and encode array N1；By the personnel of this several groups array
Coded data is compared, and number sequence is encoded by the personnel repeated, and the forward recomposition that will sort is new array M2,
Personnel are close to after certain distance, the final feature aspect ratio pair corresponding with the personnel of array M2 coding extracted, when similar
When spending highest and reaching threshold values, output personnel's coding.When aspect ratio corresponding with the personnel of M2 coding is to being not up to threshold values, then
The personnel characteristics other than M2 are compared, when reaching threshold values if there is personnel characteristics' similarity, output personnel's coding, if still do not reached
When to threshold values, judge that personal identification does not pass through, the result not communicated by the output identification of various communication modes.
Present invention uses light compensating lamp and optical sensor, the variation of induced environment light automatically adjusts red in insufficient light
The start and stop of outer light compensating lamp and visible light light compensating lamp, and automatic regulating lightness keep camera shooting imaging effect more preferable；The present invention is using infrared
Camera and visible image capturing head, comprehensive two kinds of image recognition technologys make better recognition effect；In the processor of the present invention
Default multiple facial expressions actions, can be used as special command and password, may be implemented to automatically control, the functions such as concealed alarm, carry
Height identification authentication security；The present invention uses News Search alignments, improves search efficiency and accuracy rate when comparing；This hair
It is bright compared with prior art, recognition accuracy is high, and identification method is various, easy to operate, and recognition speed is fast, and experience effect is good, more
Safety.
