Sequentially, the author discussed the technologies of medical image 3d visualization according to the clinical applications. with the development of computer, 3d visualization and computer graphics, the 3d visualization of medical images has progressed from fourier transform and convolve inverse projection to mpr ( multi - planar reformation, mpr ) and mtp ( maximum intensity projection, mtp ), nowadays, the real 3d reconstruction method, surface and volume rendering has risen. the image registering, image segmentation, pixel data set construction and 3d special interpolation are the key technologies in medical images 3d reconstruction
隨著計算機技術、三維可視化理論和計算機圖形學的發展，醫學圖像的三維可視化技術也從傅立葉變換、卷積反投影等基本圖像處理演算法，發展到真正的三維重建演算法：面繪制和體繪制；醫學圖像的三維可視化技術的應用也從三維醫學成像發展到虛擬內窺鏡，以及今天的虛擬可視化人體研究；而圖像的配準、圖像分割、體數據集的構建、三維空間插值則是醫學圖像三維可視化實現過程中的關鍵技術環節。 -
The research is significant in the situation that home information just comes into being and its growing is inevitable, by funding experiences and rendering new means for industry developing, its significance are embodied, to reach the goals above, our research focuses on four key issues, which arc as follows : ( 1 ) the concept, essence and behavior of the information home, which is still in the sprout period, is analyzed and discussed in detail from its intrinsic factors and extrinsic factors. the characters and requirements are discussed from both the microcosmic and macroscopical points
針對以上目標，本文主要從以下幾個方面對信息家居進行了深入的理論研究： 1 ）從信息家居產生的內因與外因出發，對這一處于萌芽狀態的家居形式的概念、實質和表現進行了深入的分析和論述，從微觀和宏觀的角度分析了信息家居的特性和需求，在這一思想的指導下對信息家居的體系和形式進行深入的研究，以促進信息家居的發展和成熟。 -
The sampled representation scheme is the key problem in ibr, as the data structures decide how the reference images are collected and stored as well as how the virtual images are created. we devel op a prismy panoramic model and discuss the acquisition and rendering of the datasets
圖像模型是基於圖像的繪制技術的關鍵所在，因為圖像的組織形式直接決定源圖像的採集存儲以及新圖像生成的方式和速度，為此我們提出了稜柱面全景圖模型並推導了新圖像生成演算法。 -
In this thesis, some key issues of the vr technique are systematically investigated. firstly, for the image filters and image interpolation between slices, a integrated interpolation algorithm is presented based on the contour shape and correspondence matching, which keeps the shapes and grays information the objects of interest. secondly, the fidelity of effect of the vr for medical images is studied, and a continuous - gradient - based method for transparent volume rendering is proposed, which vivifies the results of volume rendering
首先，研究了醫學斷層圖像數據的濾波及層間插值技術，提出了一種基於輪廓形變和對應點匹配相結合的混合插值演算法，在實現圖像層間插值的同時保持了目標的輪廓形狀與灰度信息；其次，對醫學影像容積重建效果的逼真度進行了研究，提出了一種基於連續梯度轉換函數的互動式透明體繪制方法，使重建效果更加生動、真實。 -
Key issues on multi - resolution representation and real - time simplification algorithms of multi - resolution of terrain model are then studied, which are simplification algorithms of dem, relativity calculation, off - line calculation, region division calculation, visibility calculation depending on fov ( field of view ) and error control, and real - time reality rendering. the simplification algorithms of self - adaptive triangulation regular networks and hierarchical triangulation irregular networks basically depending on fov are thoroughly studied. in the end, based on theories and methods discussed in this paper, a gis platform named hypergis and hyperterrain of terrain visualization software are developed and implemented
