【摘要】：近年来,随着经济的迅速发展,物流行业的崛起,叉车在物流系统中扮演着非常重要的角色。快速发展的托盘运输行业急需大量的叉车驾驶人员,目前国内叉车驾驶人员紧缺。在仅有的一些叉车培训机构中,传统叉车驾驶培训方法很难训练出大量职业化的驾驶员。国内还未出现有关叉车训练的模拟器,考虑到国内许多培训机构的经济实力,研究设计一种在普通电脑上实现叉车模拟培训系统具有重大的社会和经济意义。本论文从传统叉车培训方法跟不上人才的需求和培训机构的实力角度出发,研究在普通电脑上实现的基于VIRTOOLS的叉车模拟培训系统。首先,阐述了课题研究的背景和国内外的相关研究状况。提出系统总体设计方案和系统构成原理,提出了本课题需要解决的关键技术的问题。然后,规划整理出叉车模拟培训系统中涉及到的叉车结构、叉车培训内容、培训场地尺寸等数据。创建了三维虚拟的场景模型、叉车模型和货物模型。运用Instance实例建模、LOD模型简化、UVW贴图坐标、MIP纹理映射等算法优化场景。增强了系统视景控制过程的实时性,减轻了系统运行时系统硬件的处理负担,减少了对系统资源的消耗。论文引入PhysicCar(物理车)模块,模拟了真实的物理运动世界。论文对叉卸货物的人机交互技术进行研究。还对叉车与环境的碰撞检测进行探讨。对操作错误进行判断并对数据的结果进行反馈,形成的指导性建议,使培训计划实施的更完美。最后,论文研究了模拟观察窗口、车辆后视镜、驾驶员转头视点等多个视景观察点,实现灯光、阴影、音响功能,尝试将系统控制接口和普通的游戏控制设备联结,较好地营造出沉浸式的驾驶效果。
[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.
