【摘要】 本论文以摄影测量学及直接线性变换算法(DLT算法)为理论基础构建了多维摄像运动分析系统,并根据人体上肢的刚体矢量运动模型提出了一种基于多维摄像运动分析系统的关节转角求解方法,结合实际给出了一套用于测量人体上肢运动参数的规定动作,以便以后进行这方面的研究。 对人体运动参数的检测,离不开各种检测系统。本论文通过对几种测试系统的比较,并结合实验室现有条件,构建了一套基于普通摄像机的多维摄像运动分析系统。在第三章里,对该系统的构建原理、软硬件组成、直接线性变换算法(DLT)的应用、程序设计等几方面的内容都做了详细介绍。而且,论文中还用几个实际算例对该系统的测量精度进行了校验,并阐述了如何应用该系统进行具体实验设计。最后,论文对该系统作了初步的误差分析。 在第四章里,通过对人体上肢解剖生理结构的研究,设计了一个七自由度的人体上肢运动模型,并结合多维摄像运动分析系统提出了一套通过对标记点的跟踪拍摄来获取上肢关节转角的数学算法。该算法从刚体空间位姿变换理论出发,其所依据的数学原理简单,推导过程严密,参数意义明确,利于以后编制计算机程序。 在第五章里,论文通过对人体上肢在日常生活中各种自理活动的归纳总结,在详细分解了日常生活中各种人体动作的基础上,提出了一套ADL模拟实验动作。该套动作为以后进行此方面的测量提供了一个初步的依据,这些典型的动作作以简单组合,基本上涵盖了人体上肢在进行日常生活时各项自理活动的内容。

【Abstract】 As a packing material, glass has many advantages that cannot be substituted, such as having plenty of raw material, being produced easily, low price, stable chemical quality, not reacting with its content and so on. So it is widely used in the packing of food, beverage and chemical things. But the producing way of glassware in our country hampers the development of glass industry. Now both design of glassware and design of glassware’s module have been done by manual working. It prolongs the design period, augments the cost and makes it difficult to ensure the precision; therefore it weakens the glass competition strength as a packing material.The bottle design is the first phase of the glass bottle production. In this phase, designer has to make not only the bottle beautiful and fit to contain specific things but also its cubage meet some strict demand. Thus designer has to calculate the bottle’s volume repeatedly by dividing the bottle into many small parts, measuring the diameters of each parts one by one, calculating the volume of them approximately by treating them as cylinders, and finally summing up those volume to get the total volume of the bottle. Such boring and repeated work wastes the precious time of designer and may mean losing market to the enterprise. Designing with the computer can bring many advantages such as modification easily, calculation rapidly and exactly, and description the configuration precisely.This paper introduces a glassware design CAD system programmed with Visual C++ 6.0 and ObjectARX 2000 SDK. This system can show the plane and solid drawings of the bottle and also can simulate the finished product appearance, thus the designer can get the design bottle immediately. Besides these this system can calculate the cubage of the bottle rapidly and exactly. So it can shorten the design period, reduce the cost and improve the precision effectively.As the thinking of Object Oriented Programming is applied in this system, the characteristic data that describe the shape of glass bottles are packed in each class respectively. Therefore it is very convenient to realize the data share and add module design function to this system. Then it can finish all the work from glassware design to module design.
