Establishing 3 - d terrain models with vector contour lines and elevation terrain models with the help of the determination of space corresponding relations between contour lines, tile operation and branch operation. explanation of real - time reflection of terrain models, including three algorithms in lod technology, compared with quadtree algorithm, roam algorithm and the algorithm based on the intermediate belt, to show the advantages and disadvantages of the different situations of the terrains, so as to find out the right algorithm, the quadtree algorithm. developing and implementing the fast demonstration on the vc platform with three - dimentional visualization techniques, such as vrml and opengl, providing a persuasive argument for the research
論文首先概括介紹了用等高線快速建立3d地面模型和顯示的相關技術，並論述了課題研究的背景和選題依據;其次，論文闡述了如何對等高線數據進行預處理，提出了有效的得到矢量化等高線的方法;再次用矢量化的等高線數據建立三維地面模型，通過等高線間的對應關系的確定、瓦片操作、分支操作建立地面的高程模型;然後論文對地面模型的實時渲染問題進行了深入闡述，主要是從lod技術的三種演算法著手進行研究，通過對比四叉樹演算法、 roam演算法和基於過渡帶演算法對不同種情況的地面數據顯示的優缺點，再結合本系統的地形數據的特點選擇了適合的演算法:四叉樹演算法;最後，用vrml和基於opengl的三維可視化技術在vc平臺上開發並實現了地形的三維快速顯示系統，為論文的研究內容提供了有力的論證。 -
Expoles an algorithm about bearing surface defects detection by support vector machines that is the new branch of machine learning, in which the defective area and non - defective area are treated as two different textures and are sampled respectively to be learned, in order to reduce dimension, the image data can be processed by pca
摘要提出一種基於支持向量機的軸承表面缺陷檢測演算法，該演算法把軸承中的非缺陷區域和缺陷區域分別看作兩種不同的紋理模式，利用主成分分析法（ pca ）對圖像進行降維處理，然後用支持向量機方法對兩類不同的樣本采樣學習，進行分類判斷。 -
