Research On The System Model Of Large Groups In Monitoring Video

Currently, human group activities on a large scale, such as the OlympicGames, Football World Cup, the world expo and such rallies, are unceasinglyincreasing and the scale is larger and larger as well. These remarkable activities,bring together a large number of people all over the world. So do the shoppingmall in cities and the stars concerts. Human group activities not only promote thehuman cultural exchange and economic progress, not only boost the globalizationof the human society, but also brings to the society a lot of pressure producingmany security problems. People live in the dangerous environment, so the bigscene security has become a hotspot problem. In recent years, with the computermodeling and simulation technology being perfected constantly, it is applied inmore extensive field and make great progress in the big scene.This paper, based on physical factors, social factors, psychological factorsand other aspects when the number of people gather, puts forward stablishingcomputer simulation with social force model, which simulates the state of thecrowd in the big scene, and introduces the method of membrane computing toanalyze the state of the crowd on the basis of stimulating the big scene. Themodel lays the foundation for exploring the law in the course of state populationevolving and forecasting the future state of group system.As for the characteristics of the crowd’s movement, the main innovation ofthis paper is put forward the method of putting group as the research object ratherthan the individual that is commonly used now, and points out the correctnessand feasibility of the group study. Based on the theory of social force, it indicatesthe shortcomings of social force model and modifies the model by introducingthe black beans of experimental psychology theory. In addition, it establishes thesocial force model changed and use OpenSteer framework and VC++asp.net astechnical means to realize the stimulation of the big scene, simulating the real bigscene environment. On the basis of the realization of the simulation, Introducingthe idea of membrane computing can help us analyze the goup and directly know the movement state of the crowd gathering, which is helpful to observe theforming process of the crowd. With the evolution of membrane computingmethod, we can get laws of the state evolving and lay the foundation and createthe environment for the safety research of the crowd in a large scene.
