Research And Application Of Crowd Movement Simulation Technology In Simulation Training System

With the mature development of digital human motion simulation technology, the application of this technology is particularly rapid popularized. The virtual human motion simulation technology has become a hot spot in the field of emerging virtual human synthesis. The application of this technology is becoming more and more in all kinds of simulation training system, which make the senses of the trainees improved and make a qualitative leap for the training effects. At present. There are many researchers do the study of the simulation training system at home and abroad. But most of them just build the physical simulation environment, and do the simulation of the logical functions of various physical devices. These simulations are lack of the simulation of the behaviors and actions. So the simulation is not real enough. This article is selected under this background, combined with the related project of Chengdu***** company, aiming to do the research about the human action simulation. Then applied this research to the simulation training system to make the system more real and the training effect more apparent.Through learning the knowledge of the crowd movement simulation, this topic is aiming to put forward a suitable model of human behavior simulation according to the needs of practical application and reference existing artificial intelligence at home and abroad. And this model should be displayed in the form of 3D in the virtual environment in Unity 3D.Finally, this model can be applied to the actual simulation training system. The main research content is as follows:1. Individual behavior research:How to build the body geometry model, and generate a 3 d animation.2. Individual perception model research:Put forward a virtual human perception model based on the physiological characteristics of human perception system.3. Individual motion path planning:Analyzing the characteristics of the crowd’s path planning, then do the research and implementation of virtual crowd dynamic road planning process.4. The control model of the group behavior:the crowd is composed of multiple individuals. Analyzing the mutual influence between individuals, then choose a control model for group behavior which can be used to simulate the movement and the development trend of people.5. The application:embedding the crowd-behavior simulation into the simulation training system, ensure that it can meet the needs of training system.Research results are as follows:1. The crowd geometry model has been established, and the model can be displayed in the three dimensional and the model can go walking.2. The virtual human can aware the environmental information, which can lay a foundation for the path planning.3. The dynamic path planning of the crowd has been finished. The virtual human can choose the best path choice and can avoid the dynamic obstacle.4. Successfully combined with the simulated training system. And this technology can basically meet the expected demand.
