In recent years , the vr technique for medical images is widely used in diagnosis , surgery planning and simulating , plastic and artificial limb surgery , radiotherapy planning , and teaching in anatomy 近年来，医学影像容积重建技术在诊断医学、手术规划及模拟仿真、整形及假肢外科、放射治疗规划、解剖教学等方面起着越来越重要的作用。
In chapter 1 , a brief review is made about several relative techniques , e . g . , triangulation vs . topologic reconstruction , mesh optimization or simplification , and surface modification vs . geometric reconstruction 第一章绪论对解决曲面重建问题的几种相关技术，即三角剖分与拓扑重建技术、网格优化与简化技术、曲面造型与几何重建技术等作了简要回顾。
Several 3 - d rendering methods and their characters are analyzed . marching cubes , a kind of surface rendering method , is introduced . through the experiment on this method , the theory about cutting cubes and constructing isovalue surfaces is discussed 在对基于表面重建技术的marchingcubes ( mc )算法的研究中，着重讨论了其中剖分立方体构造等值面的原理，通过算法的实践，掌握其特点。
In this paper , the subjects of we discussed is focus on the technology of projective reconstructing and self - calibration that included in 3 - d reconstruction based on image sequence . projective reconstructing is the foundation of 3 - d reconstruction based on image sequence 射影重建是基于图象的三维重建技术的基础，它利用图象间的匹配点估计摄像机的位置和方向，为进一步的重建打下基础。
The main task of generating 3d objects from orthographic views is to construct 3d objects according to the geometric and topological information in engineering drawings , which has became an important research direction in cad / cam 基于工程图的三维形体重建技术是根据形体二维视图中的几何信息和拓扑信息生成相应的三维形体,这是一个从低维到高维的构造过程,目前已成为cad与cam中的重要研究课题。
Recent years have seen growing interest in studying of super - resolution image reconstruction technology , which refers to image processing algorithms to reconstruct high quality and high - resolution ( hr ) images from a sequence of degraded low - resolution ( lr ) images 近年来,越来越多的研究者对超分辨率图像重建技术充满兴趣,所谓图像超分辨处理就是从一序列降质的低分辨率图像中获取高分辨率高质量的图像。
In recent 20 years , advances in muscle flap surgery and availability of chest reconstructive prosthesis have encouraged the surgeons to take an active attitude toward chest wall resection ; many " unresectable " lesions now have a chance to be resected and cured 近20余年来，重建材料的发展和软组织重建技术的进步让外科医生在胸壁切除时更为积极，胸壁重建取得了很大的进步，许多在过去“不可切除”的病变得到了治愈的机会。
Realizing to put image record , transaction , editor , export and printing report forms technology together solving the question which the wheel is long for producing the plate of tradi tional photographs and developing films , and witch it ' s uneasy to take care of for low product rate 本文通过对图像分析仪、共聚焦显微镜的研究，深入浅出地探讨了图像处理技术、图像分析技术、图像压缩技术、图像拼接技术、三维重建技术。
Also , this soft ware can achieve spatial interpolation , construction pixel data set . the 3d liver reconstruction is based on volume rendering algorithm , and the interactive operation of rotation and incision on reconstructed liver can be accomplished with the proposed software very 作者在本论文中通过对三维数据可视化理论、医学图像三维重建技术及实现方法的分析和研究，设计了一套实用的基于腹部ct平片的肝脏三维重建软件。
It calculates recreational and fishing loss by economic loss rate of water due to pollution in 2005 . it gains civicism project and water pollution recovery investment , water pollution accident loss by investigating and interviewing from wulateqianqi bureau of water conservancy , environment protect bureau and so on 基于上述分析,探讨了乌梁素海水环境恢复和重建技术途径,提出从富营养化控制和经济手段、行政手段、法律手段等方面的治理及保护对策。
