High precision test needs.
The one of the present invention is based on multi-sensor fusion technology Initiative Defense intelligence intrusion detection equipment, its Concrete workflow
Journey is as follows:
When high accuracy infrared thermal imaging module has detected that heat source thermo is swarmed into, by embedded based on artificial neural network
Complex environment Intelligent target is followed the tracks of and recognizer calculates swarming into object overall dimensions, is filled into toy and swarms into feelings
Condition, then carry out scanning by phased array radar detection module to swarming into object, confirm that swarming into object is entity, removes high light, sun
Light direct beam causes wrong report, when both confirm errorless after, start high-definition intelligent video monitoring module, by intelligent behaviour analytical technology
Judging to start early warning mechanism when messenger has vandalism, carry out sound and light alarm retention of taking pictures, be sent to main frame, then main frame leads to
Cross GRPS communication and send multimedia message to master cellular phone.
Follow the tracks of and recognizer based on artificial neural network complex environment Intelligent target
Moving target intelligent-tracking and identifying in complex environment, is contaminated with a lot of complicated back of the body due in the feature extracted
Noise in scape, therefore, traditional characteristic extracts tracking and recognizer is difficult to by building the moving target of complex background
Mould, reaches the purpose of moving target intelligent-tracking and identification；The present invention proposes based on artificial neural network complex environment target
Intelligent-tracking and recognizer can solve this difficult problem, and the calculating process of this technology is, first from a bigger feature set
The key feature that middle selection is a small amount of, produces a few efficient grader, then synthesize by the way of cascade one complicated
Grader, in generating complex classifier, by BP artificial neural network technology, divides rate (FPR) and positive sample by the mistake of negative sample
This mistake point rate (FNR) limits the weight degrees of expansion of wrong point of sample；The process that implements for being divided into positive class or negative by sample
Class, has real class (TP), false positive class (FP), really bears class (TN) and four kinds of situations of class (FN) are born in vacation, represent positive class, 0 expression with 1
Negative class, tetra-indexs of existing TP+FN, FP+TN, TP+FP and FN+TN, these four indexs can be formed again two variable FPR and
FNR, wherein FPR is false positive class rate, and expression is that negative sample is categorized as the probability of positive sample by mistake, and computing formula is FPR=FP/
(FP+TN), the most all negative samples are categorized as the quantity of positive sample and the ratio of whole negative sample quantity by mistake；FNR is false
Negative class rate, represents that positive sample is categorized as the probability of negative sample: FNR=FN/ (FN+TP) by mistake, wrong in the most all positive samples
It is mistakenly classified as the quantity of negative sample and the ratio of the most positive sample size；It addition, use ROC curve, (i.e. Receiver Operating Characteristics is bent
Line) it is used for evaluation objective detection method accuracy.
The application follows the tracks of and recognizer based on artificial neural network complex environment Intelligent target, is come by two steps
Realize:
(1) in learner, sample weights updates, and computing formula is:
Wherein ωT, iRepresent the feature weight of the i-th sample circulated the t time,
β=-log αt∈(0,1),Such as i-th sample the t time circulation by Weak Classifier
When correctly classifying, εt=0, otherwise, εt=1.
(2) sample weights normalized in learner
In learner, sample weights normalized is to carry out in whole sample space, after normalization, has both kept mistake
Classification samples weight, decreases again the sample weights of correct classification, and on proceeding in iteration once, the sample divided by mistake is subject to
Attention degree is higher.
Computing formula is:
Number of samples during N is learner in formula, ωT, iIt is sample weights before global characteristics normalization,It is normalization
Rear sample weights.
The most both can ensure that the weight of difficulty sample was continuously increased in learning process, each weak study can have been equalized again
The weight of device, meanwhile, this algorithm selects a small amount of key feature from a bigger feature set, produces efficient learner, again
Synthesize complex classifier by cascade system, can quickly abandon image background regions, detection region is concentrated on complex environment
In there is motion target area, accuracy rate and the robustness of motion target tracking and identification can be effectively improved, and then realize complexity
The intelligent-tracking of moving target and identification in background.

As i-th sample follows at the t time
When ring is correctly classified by Weak Classifier, εt=0, otherwise, εt=1.
(2) sample weights normalized in learner
In learner, sample weights normalized is to carry out in whole sample space, after normalization, has both kept mistake to classify
Sample weights, decreases again the sample weights of correct classification, and on proceeding in iteration once, the sample divided by mistake is paid attention to
Degree is higher.
Computing formula is:
Number of samples during N is learner in formula, ωT, iIt is sample weights before global characteristics normalization, ωT, iIt it is sample after normalization
This weight.
