This articles about is approaches to creation of video analytics information-measuring systems and presented own method of creation of system of automatic identification of emergency situations, on the basis of an assessment of a vector of the measured parameters by means of fuzzy models. The main stages of processing of video sequence by means of the offered method are presented. In this articles presented moving object detection methods. The method of representation of life cycle of mobile object consisting of consecutive transition of object from the phase "emergence" in the phase "maintenance" with the subsequent exit of object from an observed zone – the phase "disappearance" is offered.
The method of obtaining parameters of a situation consisting in consecutive allocation from a set of mobile objects, a set of the interesting objects, identification of the interesting objects, definition of a trajectory of the received objects and determination of parameters on trajectories of their movement is offered. The method of the interesting objects detection based on use of a vector of signs which components possess low computing complexity is presented. The method of creation of the vector of signs used for identification of the interesting objects is offered.
The method of allocation and classification of the emergency situations based on use of fuzzy logic and creation of the indistinct models constructed for an assessment of the measured parameters characterizing a situation is offered. It is presented a vector of the parameters used for an assessment of situations, and classification a component of a vector of parameters on scales of measurements is also given.
The method of construction and updating, the used models is offered. Criteria for evaluation of accuracy, classification of the found emergency situation are offered. The method of a defazzifikation of decisions on type supernumerary the situations received as a result of work of the offered models is offered. Methods of classification of an emergency situation as services which can be used for elimination of this situation are offered.
Presented advantages of use of the offered approach to creation of information and measuring system of classification of a situation in an observed zone are presented and results of experiments are given.
Keywords:video analytics, anomaly detection, information-measuring systems, emergency situation detection, fuzzy models, decision theory.
