Wherein, K1, K2, K3, K4The significance level that represents each factor.
C. calculate the video analysis degree of confidence,
Utilize decision function to calculate the video analysis degree of confidence, when degree of confidence surpasses default threshold value, then need not to revise, direct output alarm signal, otherwise continue next step.
D. comprehensive confidence calculations,
As video analysis degree of confidence result during less than predetermined threshold value, calculate and survey degree of confidence:
Z(T)=K5Y5(T)
Wherein, T represents the number of times utility value of infrared continuous trigger.
Utilize Z (T) that video analysis degree of confidence Y (v, x, t, g) is revised, determine whether according to correction result and carry out alerting signal output.Modification method is as follows:
Y(v,x,t,g,Z)=U(K1Y1(v),K2Y2(x),K3Y3(t),K4Y4(g),Z);
Wherein, U represents that above-mentioned several element consists of an atomic event.
If e. Y value does not reach the threshold value of warning, utilize simultaneously the sample classification data that pattern match is carried out in the moving region, the space geometry that mainly mates Corner Feature distributes, if coupling reaches alarm threshold, reports to the police equally.
In the above-mentioned steps, no matter when which step judgement need to be reported to the police, then the local panalarms such as guide sound, light, electric alarm equipment were reported to the police, and simultaneously warning message are transferred to target platform or terminal by network interface.
By adopting the disclosed technique scheme of the utility model, obtained following useful effect:
Intelligent visual warning system of the present utility model, video acquisition device and detection alarm device are combined common judgement security protection field condition, the advantage of video image analysis technology and object detection technology is incorporated into all over the body, keep an eye in the situation that need not the special messenger, reduced to greatest extent the wrong report of warning device and the possibility of failing to report.Alarm method of the present utility model is applied on the intelligent visual warning system of the present utility model, effectively prevented because of the interference of the environmental factors such as light, shadow to video image, adopt the multiple analysis algorithm, analysis-by-synthesis is carried out at the security protection scene, thereby greatly improved the accuracy of security alarm.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be looked protection domain of the present utility model.
