【摘要】：近年來,隨著經(jīng)濟的迅速發(fā)展,物流行業(yè)的崛起,叉車在物流系統(tǒng)中扮演著非常重要的角色。快速發(fā)展的托盤運輸行業(yè)急需大量的叉車駕駛?cè)藛T,目前國內(nèi)叉車駕駛?cè)藛T緊缺。在僅有的一些叉車培訓機構(gòu)中,傳統(tǒng)叉車駕駛培訓方法很難訓練出大量職業(yè)化的駕駛員。國內(nèi)還未出現(xiàn)有關(guān)叉車訓練的模擬器,考慮到國內(nèi)許多培訓機構(gòu)的經(jīng)濟實力,研究設計一種在普通電腦上實現(xiàn)叉車模擬培訓系統(tǒng)具有重大的社會和經(jīng)濟意義。 本論文從傳統(tǒng)叉車培訓方法跟不上人才的需求和培訓機構(gòu)的實力角度出發(fā),研究在普通電腦上實現(xiàn)的基于VIRTOOLS的叉車模擬培訓系統(tǒng)。首先,闡述了課題研究的背景和國內(nèi)外的相關(guān)研究狀況。提出系統(tǒng)總體設計方案和系統(tǒng)構(gòu)成原理,提出了本課題需要解決的關(guān)鍵技術(shù)的問題。然后,規(guī)劃整理出叉車模擬培訓系統(tǒng)中涉及到的叉車結(jié)構(gòu)、叉車培訓內(nèi)容、培訓場地尺寸等數(shù)據(jù)。創(chuàng)建了三維虛擬的場景模型、叉車模型和貨物模型。運用Instance實例建模、LOD模型簡化、UVW貼圖坐標、MIP紋理映射等算法優(yōu)化場景。增強了系統(tǒng)視景控制過程的實時性,減輕了系統(tǒng)運行時系統(tǒng)硬件的處理負擔,減少了對系統(tǒng)資源的消耗。論文引入PhysicCar(物理車)模塊,模擬了真實的物理運動世界。論文對叉卸貨物的人機交互技術(shù)進行研究。還對叉車與環(huán)境的碰撞檢測進行探討。對操作錯誤進行判斷并對數(shù)據(jù)的結(jié)果進行反饋,形成的指導性建議,使培訓計劃實施的更完美。最后,論文研究了模擬觀察窗口、車輛后視鏡、駕駛員轉(zhuǎn)頭視點等多個視景觀察點,實現(xiàn)燈光、陰影、音響功能,嘗試將系統(tǒng)控制接口和普通的游戲控制設備聯(lián)結(jié),較好地營造出沉浸式的駕駛效果。
[Abstract]:In recent years, with the rapid development of economy and the rise of logistics industry, forklift truck plays a very important role in logistics system. The rapid development of pallet transport industry is in urgent need of a large number of forklift drivers, the current shortage of forklift drivers in China. In only a few forklift training institutions, the traditional forklift driving training method is difficult to train a large number of professional drivers. There are no simulators for forklift training in China. Considering the economic strength of many training institutions in China, it is of great social and economic significance to study and design a forklift training simulation system on ordinary computers. From the point of view that the traditional forklift training method can not keep up with the demand of talents and the strength of training institutions, this paper studies a forklift simulation training system based on VIRTOOLS. Firstly, the background of the research and the research situation at home and abroad are described. The system overall design scheme and system constitution principle are put forward, and the key technical problems that need to be solved in this subject are put forward. Then, the data of forklift truck structure, forklift training content, training site size and so on are sorted out in the forklift simulation training system. Three-dimensional virtual scene model, forklift model and cargo model are created. Instance case modeling, LOD model simplification, UVW mapping and MIP texture mapping are used to optimize the scene. It enhances the real-time performance of the system visual control process, reduces the processing burden of the system hardware while the system is running, and reduces the consumption of the system resources. In this paper, PhysicCar (physical vehicle) module is introduced to simulate the real physical movement world. In this paper, the man-machine interaction technology of fork-unloading cargo is studied. The collision detection between forklift truck and environment is also discussed. To judge the operation error and feedback the result of the data, form the guidance suggestion, make the training plan carry out more perfect. Finally, the paper studies several visual observation points, such as simulated observation window, vehicle rearview mirror, driver's turning view and so on, to realize the functions of lighting, shadow and sound, and try to connect the system control interface with the common game control equipment. Better create immersive driving effect.
