澳洲墨尔本论文代写:基本理论

纹理是法的基本理论:一个表面光滑并具有重复纹理单元覆盖的对象,当投影在二维图像上纹理单元将产生变形,这种变形分为投影变形(射影失真)和透视收缩。投影变形所以远离图像平面纹理单元看起来较小的透视失真和图像平面进行角较大的纹理单元看起来更短。因为这两个变体可以从图像中测量出来,所以它可以分析变形后的纹理单位,反向打击物体表面的法线和深度信息,进行三维重建。三维视觉重建技术还处于探索阶段,实际应用中的各种方法还有一定距离,需要从各种应用中得到满足。因此,在今后相当长的一段时间内,我们还需要对这一领域进行更深入的研究。研究表明,BIM可以为桥梁的设计和施工提供有效的支持。本文的研究成果可望为提高大型复杂桥梁设计和施工的效率和效果,以及在土木工程领域推广应用BIM提供参考。笔者认为,随着BIM理论和技术的不断推广,BIM在土木工程中的应用将越来越广泛,以提高其质量、效率和管理水平。安全关键结构桥梁工程后期维护、运营管理、档案管理可以利用BIM强大的信息技术,实现可视化能力。

Texture is the basic theory of law: For a smooth surface and having a repeating texture units covering the object of which, when projected on the two-dimensional image, texture unit on which will be deformed, this deformation is divided into projection distortion (projective distortion ) and perspective shrinkage. Projection distortion so the farther away from the image plane texture unit looks smaller foreshortening distortion and image plane makes an angle greater texture unit looks shorter. Because these two variants can be measured from the image, so it can be analyzed after deformation texture units, reverse strike the surface normal and depth of information, three-dimensional reconstruction. Reconstruction of 3D Vision technology is still in the exploratory stage, the practical application of the various methods is still some distance away from a variety of application needs to be urgently met. Therefore, in the future for a long period of time, we also need to do more intensive research in this field. This study shows that, BIM can provide effective support for the bridge design and construction. This study was expected to provide reference for increasing large, complex bridge design and construction efficiency and effectiveness, as well as assist in the promotion and application of BIM in the field of civil engineering. I believe that with the continuous promotion of theory and technology of BIM, BIM applications in civil engineering will become increasingly widespread, so as to improve their quality, efficiency and management level. Safety-critical structural bridge engineering, maintenance and repair of the late, operations management, file management can take advantage of powerful information technology BIM, visualization capabilities to achieve.
