Abstract: The content and the structure of the video vary with the video type. The video data of the training system can be further mining by introducing the idea of video structure mining to solve the human-computer interaction problems for the present state and the problems of simulation training systems. The video structure of the training system was defined and the improvement of the video structure framework of the available simulation training systems is proposed in combination with the concept framwork of the video structure mining. Under this framework， the improvement methods can optimize system structure， obtain the high level semantic information，make the system more intelligent andprovide the instruction for dicision of the training approach or improvement of the training quality.Keywords: video data; video structure mining; analog simulation;training system

計(jì)算機(jī)仿真技術(shù)和可視化技術(shù)的應(yīng)用[1-2] 在模擬仿真培訓(xùn)系統(tǒng)中可以帶來巨大的社會(huì)效益和經(jīng)濟(jì)效益。隨著計(jì)算機(jī)的發(fā)展和圖形技術(shù)的進(jìn)步，模擬仿真培訓(xùn)系統(tǒng)要求仿真可視化更加直觀、逼真和具有良好的人機(jī)交互能力。本文嘗試以基于視頻的模擬仿真培訓(xùn)系統(tǒng)為研究對(duì)象，通過挖掘其視頻結(jié)構(gòu)中語法模式和語義規(guī)則，合理優(yōu)化培訓(xùn)系統(tǒng)視頻單元結(jié)構(gòu)，為提升培訓(xùn)質(zhì)量提供理論指導(dǎo)。

原始視頻是一種非結(jié)構(gòu)化時(shí)基媒體，通過視頻的結(jié)構(gòu)化可以實(shí)現(xiàn)計(jì)算機(jī)的有效管理、訪問和檢索。……
