  1. Through analyses of epipolarity geometry of the linear ccd push - broom images and frame perspective images, based on the projection track method, epipolarity of linear ccd push - broom image is established and the properties of epipolarity curves is discussed, and a new epipolarity model based on the simplified push - broom sensor model is proposed. for stereo images of frame perspective and linear perspective, how to set up of epipolarity is studied in terms of fundamental matrix in computer vision, and an algorithm of epipolarity solution that only depends on coordinates relation of identical point is presented. 4

    通過線陣ccd推掃式影像和框幅式中心投影影像核線理論的對比研究，利用投影軌跡法建立了線陣ccd推掃式影像的核線模型，分析和總結了它的基本特性；針對基於共線方程的簡化傳感器模型，提出了一種新的核線模型；對框幅式中心投影立體影像和線陣ccd推掃式立體影像，利用計算機視覺中的基本矩陣研究核線關系的建立，提出了一種單純依靠同名點坐標關系的核線模型解法； 4
  2. First calculation method : doing horizontal projection drawing on drawing piece, k value is introduced by area equation of projection drawing, k value is obtained by area equation, along outline of projection drawing to add k value, that is, outline shape of blank drawing, principle area - equal and shape similar are used. second calculation method : along outline of drawing piece horizontal projection drawing, to do normal line of penetration line for wantonly point of this point, to obtain high of drawing piece on this point normal line, point and point is to form outline shape of blank

    計算方法之一為k值法：作拉深件水平投影圖，在該投影圖面積方程中引入k值，利用面積相等原理解方程，求得k值，沿水平投影外沿加上k值，即為毛坯圖的外廓形狀。計算方法之二為拉深線法：沿拉深件水平投影圖外廓，在任意點作該點切線的法線，在該法線上以該點拉深件的高度為量，在法線上取截點。
  3. The object of single photon emission computed tomography ( spect ) is to reconstruct an unknown radioactivity distribution inside the body from projection data consisting of the number of photon collected on a collimated gamma camera. these projections are not simple line integrals but have point - spreads due to the imperfect collimator of the detector and attenuation due to the compton scattering. so

    這種投影數據與透射ct中的數據不同，由於存在著光子的點擴散（由準直器引起）和衰減（由散射引起） ，已經不能用簡單的線積分來描述這個問題，因此相對于透射ct而言，這個領域將面臨很多困難。
  4. A novel approach of large - scale surface 3d measurement is proposed which combine multiple view motion vision measurement, digital fringe projection measurement and iterative closest point registration. the measurement techniques is rapid, portable, easy to operate and large measurement area. compared with the existing methods, the accuracy of surface merged is not dependent on high accuracy of feature point measurement, but determined by iterative closest point registration

    論文提出了一種集成多目運動視覺特徵點測量、數字相移條紋投影曲面片測量和最近點迭代配準拼接的大型三維曲面測量新方法，具有快速、便攜和量程大的特點，與目前的集成系統相比，曲面配準拼接精度不依賴高精度的特徵點測量，而是採用多目運動視覺特徵點測量結果作曲面初始配準拼接，然後再通過最近點迭代法實現精確拼接。
