  1. Analysis the relation between the w2h model element though anglicizing the section and the projection of the 3d spatial model

  2. There are mainly two type of algorithms used for spatial spectrum estimation : one is those based on bayesian maximum likelihood method, like the ml ( maximum likelihood ) algorithm, maximum entropy method and etc., the others are based on the spatial decomposition or projection of correlation matrix, this kind of algorithm include vector characterization method, music ( multiple signal classification ) algorithm, projection matrix method, etc. music is a classical spatial spectrum estimation algorithm that has a super high resolution and is widely used today, however, it cannot estimate doa of signals that are correlated

    空間譜估計的演算法大致分兩大類:一是基於極大似然估計和最大后驗概率估計統計理論的演算法，包括:極大似然估計法（ ml ） 、最大熵法等;另一類是基於對協方差矩陣進行子空間分解或投影的演算法，包括:矢量特徵法、多重信號分類法（ music ） 、投影矩陣法等。其中， music法是一種經典的空間譜估計主流演算法，具有超強的分辨性能，但它無法實現對相干信號進行測向分辨。
  3. This study choosed arc view gis by way of foundation platform and developed the function modules for region geophysics and geochemistry ( for example hydrological function and background analyst for region geochemistry and transformation for potency field and transformation of map projection and correlation analyst and grid data treating and inserter for kriging and trend and so on ) except using the basic functions of arc view gis ( e. g. neighbour analyst and spatial data treating and surface analyst and model constructor and so on )

    本論文選擇arcviewgis作為基礎平臺，除利用arcviewgis的基本功能（如鄰域分析、空間數據處理、表面分析、模型構造器等）外，開發了適合於區域地球物理地球化學綜合解釋的功能模塊，如水文功能、區域地球化學背景分析、位場變換、地圖投影變換、相關場分析、柵格數據處理、 kriging及trend插值器等。
  4. The distinct feature of this approach is to reconstruct the 3d model of target from images progressively in accordance with the general modeling conventions. namely, user firstly determines the rough model and puts projection and spatial constraints on it as well as topological operations step by step to let the system recover the camera parameters and refine the model

    該方法的主要特點在於，按照一般人的建模習慣，由粗到細地通過圖像重建目標三維模型，在確定大致形狀的基礎上，由用戶添加或者修改投影約束與空間約束，並施加拓撲修改，逐步實現照相機定標，粗糙模型的求精，並最終完成對具有任意幾何及拓撲物體的重建。
  5. In order to acquire 3d spatial position and motion parameters of moving target, the limitation of second focus method to get the depth of target is analyzed according to perspective projection model of target centroid. then, the constraint for obtaining 3d position and motion parameters of moving target centroid from monocular image sequence is presented and proved in this paper. with this constraint, a nonlinear extended kalman filter algorithm for estimating 3d spatial position and motion parameters of moving target centroid from monocular image sequence is proposed

    進一步，為獲取目標的空間位置和運動參數等三維信息，在目標和成像系統都運動的情況下，根據目標質心的透視投影成像模型，首先分析了二次成像法獲取目標深度信息的缺陷；然後給出了由單目序列圖像獲取目標質心的空間位置和運動參數的條件，並提出利用多幀單目序列圖像和應用非線性擴展卡爾曼濾波演算法來估計目標質心的空間位置和運動參數；最後對提出的估計方法進行了多組模擬驗證，證明該方法可行有效。
  6. At first, this paper brings forward its investigative intent and meanings and introduces the features, the basic contents and developing status, etc. gis, as a kind of decision - making and supporting system, is based on geographic spatial database and timely provides many kinds of spatial and dynamic geographic information for serving for geographic research and decision - making ; it discusses and analyses map projection of gis and finds the two directional computation for gauss - kruger can make up the lacks of gis in map projection

    本文首先提出研究的目的和意義，介紹gis的特點、基本內容及其發展狀況等；地理信息系統作為一種決策支持系統，以地理空間數據庫為基礎，實時提供多種空間的和動態的地理信息，為地理研究和地理決策服務；探討和分析gis中的地圖投影，發現高斯-克呂格正反算可以彌補gis系統在地圖投影上的不足。
  7. The algorithm acquires the quantity of two - dimensional spatial translation by means of projecting each frame apart along horizontal and vertical direction and using multi - resolution spectrum decomposition approach to process the two projection vectors, respectively

    該演算法首先引入積分投影方法將圖像序列中的每幀圖像轉換成兩個一維積分投影向量，再應用多分辨譜分解方法對兩個投影向量分別進行處理，從而精確地獲取圖像在二維空間上的亞像素平移量。
  8. Normally, in current projection system, three array pixel type spatial light modulator devices were used to form three primary colors image in the projection display. to achieve the high performance projected images, the three slm devices must be adjusted precisely and superposed three primary colors images exactly one by one in space. it is means the correspondent pixels of the three colors " pixel devices must be overlapped exactly

    以目前得到廣泛應用的三片式陣列像素器件投影顯示為例（如液晶投影顯示） ，在投影鏡頭成像質量達到要求的情況下，要得到清晰的圖像，還要求精確調整三片陣列像素器件的空間位置，使得陣列像素器件成像清晰，而且對應像素經成像后精確重合。
