  1. The paper presents several aspects in partition rectification and visualization of raster image. adopt technology of visualization for scientific calculation, vector diagram of deformation 、 contour chart of deformation and drawing of three - dimensional are realized. delaunay tin in view of deformation feature is constructed on base of selected grid control points and methods and mathematical models for partition rectification are realized based on the delaunay tin. software of geometric rectification for large scales are realized and applied in project

    本論文針對柵格影像的變形可視化及分塊糾正展開研究,取得了以下幾方面的研究成果:一、採用科學計算可視化技術,繪制變形矢量圖、變形等值線圖和三維效果圖,實現了柵格影像變形特徵的可視化;二、提出了在格網控制點( gcp )數據基礎上選擇性構造顧及變形特徵的delaunay三角網,並基於構造的三角網實現了分塊糾正的方法和數學模型;三、採用vc編制了影像幾何糾正軟體,實現大比例尺掃描地形圖的糾正,並在工程中得到應用。
  2. Meanwhile, in 3d - scene, some functions of spatial analysis and interactive operations have been realized. and, a testing application system of 3dcm is developed, which includes tin model construction, the creation of contour, spatial coordinate query, section - cutting, measuring distance and area, 3d visualization and operation about topography and building etc. the purpose of developing testing system is to demonstrate the correctness of 3dcm based on the visualization. finally, the result of the testing and 3dgis research direction is put forward to investigate generally

    另外,在三維模型的可視化場景中,實現了一些3dgis的交互操作和空間分析功能,結合論文的目標,開發了一個實驗系統,對三維城市的建模方法進行了論證,實現了dem模型的快速構建及等高線的追蹤和地圖分幅,實現了三維城市模型的可視化,在可視化的基礎上實現了部分空間交互操作和空間分析,如:空間坐標查詢、斷面切割、距離和面積量算、建築物屬性查詢、三維動態漫遊等。
  3. 4. utilizing the discrete points data of crp objects, we firstly realized the modeling method based on tin and modal display, and then formed the contour graphu stereo graph, profile graph, at last we obtained the result of standard data format

    利用近景對象離散點數據,實現了基於三角網格的物體建模與模型交互顯示和等值線圖、立面圖、剖面圖的生成,並給出標準數據格式的結果。
