- Using the multi - cloud model to fit the ha - spectra data of the april 27 , 1981 post flare loop , we obtained the spacial distributions of the four physical parameters in the space of the post flare loop : the line - of - sight velocity v the excitation temperature tex , the micro - turbulence velocity vt and the column number density of the hydrogen atoms at the second level along the line - of - sight direction fields n2
我们利用多云模型处理了1981年4月27日太阳西边缘耀斑后环的三个时段的h光谱扫描资料。通过对1000余条对称谱线和不对称谱线的计算，我们得到了该耀斑后环各个时段在空间上的视向速度场，激发温度场，视向上处于第二能态的氢原子柱密度场以及湍流速度场。 - Innovation of the aero maintenance system based on augmented reality ( ar ) technology and eye tracking technology , which can give real - time instruction for maintenance , is vital for enhancing the accuracy of maintenance and reducing the cost of maintenance . in the paper , the study work include 3 sections , as following : firstly , deducing 3d registration algorithm based on markers , depicting the display and 3d display technologies of artificial matters , and realizing 3d registration function specifically ; secondly , establishing an eye - movement measurement system based on the infrared television method , making use of the thoughts of ranks superimposition to withdraw the pupil center coordinates , and giving the thaught of recombining the position relation of purkinje spot to determine the eye sight direction primarily ; finally , describing the basic theory of augmented reality maintenance guiding system in detail , and introducing the software function and hardware frame , which will provide the foundation for the further study of this system
本文的研究工作主要包括以下三个部分:首先,改进了有标志点的三维注册算法,并具体实现了三维注册功能,最后试验验证了注册算法的正确性,为将来基于无标志点的发动机维修诱导系统的研究提供基础和实践经验;其次,描述了基于红外电视法的视线跟踪系统的基本原理,对眼动信号处理技术做了初步的研究,即利用了行、列叠加的思想提取了瞳孔中心坐标和普尔钦( purkinje )斑点的坐标,阐述了结合瞳孔中心与普尔钦( purkinje )斑点的位置关系进行初步判定视线方向的方法;最后,详细描述了所构建的增强现实维修诱导系统的基本原理、软硬件框架,为今后维修诱导系统的深入研制提供基础。
