The Research And Realization Of The Multi-Police Cooperation And Virtual Exercise Platform

With the rapid developments of computer technology, communication technology and other related technologies, the visualization of information has been the new application field, and the simulation technology based on virtual reality also has been the focus of current study. The routine training of police arresting, which is restricted by many realistic difficulties, can be a waste of money and material resources and has a low efficiency. Therefore, it is very necessary to build a visible system that can be used to virtual training and tactics investigation and commanding.This paper analyses the developments and appliances of virtual reality in foreign countries, builds up a virtual multi-police cooperated controlling and training platform, which includes three-dimensional modeling of the arresting scene and character modeling, achieves the function of arresting in the virtual scene and of replaying the video of process. The followings are the detailed tasks which have been done in this paper.1. This paper has summarized the progress of research and application of the visual reality technology and tactics drilling system, expounded the practical meaning of this question for discussion, put forward the research goal and contents aimed at the practical requirements.2. To analyze and compare the relative software and technology In this paper, the author has also proposed the master design of the virtual multi-police cooperated controlling and training platform and the ways to achieve it.3. With the use of the three-dimensional modeling software MultiGen Creator to construct the visual scene of arresting, the author adopted various technologies such as Instance, External Reference, Textual Mapping, etc. in the processing. After setting up the database of the scene, the model has been optimized with the adoption of LOD technology.4. Use the software development kit DI_Guy from Boston Dynamic Co. to build the character model, of which the figure is built by joint body structure.5. By using the visual scene drive engine Vega to realize the walkthrough and simulation in virtual environment and introduced the design method and the achieving process of visual simulation system.6. It has also introduced the design and realization of the functions of video and replay of the simulation process in the end. Have analyzed the structure of AVI document, and realized the creation of AVI document with the use of programme.The exploited practical police battle drilling system, hanged each landform together with tactics drilling, has offered a more vivid visualized platform for the leaders'use in commanding and decision making and has played an important role in police actual application.
