Because of the presence of the difference of the gray value and the distortion between the object image and the reference image, traditional matching method will be degraded. We need more useful characters. Eigenspace approach is a promising candidate for an appearance-based object representation.

文中提出基于奇异值分解的跟踪算法，算法首先建立模板图像训练集合，利用奇异值分解方法，张成模板图像特征空间，然后求出模板图像在特征空间里的投影值，代替传统算法中灰度对两幅待匹配图像进行的全局搜索定位。

While the idea and the prototype of the three-degree-of-freedom motor came into being, it is more convenient to realize the motion of the robot joint where the demand on workspace is low but three DOF is required. It also combines the merits of simplified system construction, minimized machine volume, improved dynamic and static performance with high position accuracy.

The model of the thesis s forecasting method is synthetical use of experience model method and mine-reserach information adding power model method of mineral resources assessment based on GIS. It use several kinds of analysis means for multi-sources data. Firstly the gold-research prospective domains of this area are forecasted through the spatial query and ana-lysis by means of GIS,based on geological and mineral information of thearea, synthesizing geochemistry anomaly information. Gridding inserting value transforms geochemistry data of sampling point of the south of Acixiarega from scattering data to grid data by means of the development of Delphi and Mapobjects, using distance reciprocal inserting value method. After deposit orientation analyse and spatial overlapping analysis by means of CIS, the gold-research prospective domains of the area are forecasted.

Taking Changling County, Zhenlai County and Da'an City of Jilin Province as researchareas, based on remote sensing data, graphics operation and spatial analysis are carried out indifferent points of views, including temporal, spatial, scale and landscapeetc; all aspects analysis of this dissertation are abstractively expressed by digital graphics andseries of curves which are not stick to one pattern to discussing multi-dimension andcomplicated attributes of the salinized process. Linking up temporal-spatial characteristicswith landscape indices while combining mathematics model and Geo-informatic TUPUmodel, this dissertation puts forward the fundamental frame: temporal-spatial evolvementpattern, spatial extension process analysis and landscape characteristics analysis of salinizedland. Temporal-spatial evolvement pattern analysis extracts the essential quantity features andtransformation modes of salinized land, and also analyzes patches spatial geometricalparameters scale feature; spatial extending process analysis discusses the change rate andecological modes; landscape feature analysis utilizes landscape graphics indices to describesalinized land microcosmic graphics features and changes.

In this thesis, we proposed a robust trilateration method to estimate Path Loss Exponent which stands for the signal attenuate rate for each reference node to target path by using two different frequency signals and the trilateration method. Then we used every PLE to calculate the corresponding distance and performed the trilateration positioning task using these distances. We also ran two simulations to evaluate our proposed method.

但另一方面，即使在同一空间中，却因为存在著许多变数而导致各个不同的路径都拥有自己的路径衰减指数，所以此篇论文我们提出先利用两个不同频率的讯号测得参考点到目标上的路径衰减指数后，再利用此数值做此路径的距离推导，最后再藉由三点定位法做出目标的定位。
