Study And Application Of Virtual Human Technology In Training Simulation

This paper focuses on the key problem of the application of virtual humantechnology in training simulation, summarizes the basis framework of common trainingsimulation system, proposes the framework of training simulation system based on thevirtual human technical, multi-style virtual human walking motion generation andvirtual crowd behavior model are deeply researched. The main achievements areobtained as follows:First of all, according to poor variability of the traditional virtual human motiongeneration method, this paper proposes a variety virtual human walking motiongeneration method. First we analyses the motion data by the PCA (PrincipalComponents Analysis) method to change movement properties, and by the ICA(Independent Component Analysis) method to change movement type; Finallycombining PCA method and ICA method, the user can get different properties and typesof the virtual human walking motion through a amount of motion data.Secondly, according to poor fidelity of virtual crowd behavior, on the basis of thetraditional virtual crowd social force model, this paper consider the angle and range ofthe virtual person view, proposes a psychology and geometric rules based on parametricsocial force model. Through the improved model to realize the virtual crowd’s basicbehavior, and finally the believable crowd behavior animation are obtained byintegrating them.Finally, according to lack of simulation to the realistic motion and behavior ofhuman and crowd in the current training simulation system, on the basis of theconclusion of the framework of the training simulation system, this paper proposes atraining simulation system framework based on the virtual human technical, multi-stylevirtual human walking motion generation and virtual crowd behavior model are appliedto the training simulation system, realize to human and crowd simulation.This paper designs and implements a training simulation system based on virtualhuman technical, formed the realistic virtual human and crowd behavior animation,increase the fidelity of training simulation system, and prove that the algorithm ofmulti-style virtual human walking motion generation and virtual crowd behavior modelis feasible and accurate, solve the key problem of the application of virtual humantechnology in training simulation system.
