三维激光扫描仪造船测量需求分析.doc

PAGE PAGE 30 摘 要 本文从当今世界造船业的发展现状及我国造船技术和世界先进造船技术的差距入手，介绍了在船体制造中现有的几种测量系统，提出造船测量的需求，并在三维激光扫描仪原理的基础上，从三维激光扫描仪的软硬件方面设计满足需求的方案，并经过实验和与现有的测量系统在各方面的对比，说明三维激光扫描仪在高效获取船体三维数据，提取船体型线方面有着较大的优越性。 关 键 词：造船，测量模式，三维激光扫描仪，需求分析，点云数据的处理 ABSTRACT The developing present situation of shipbuilding on the modern world and shipbuilding status in China is introduced in this article. Through these conditions, the technique disparity between our China and the advanced technique is obviously. This academic introduce the survey systems of shipbuilding in the present dockyard, and bring up the survey requirement of the shipbuilding process. On the foundation of the 3-D laser scanner theory, design survey formula of the 3-D laser scanner from the hardware and software, then through the experimentation of 3-D laser scanner use in ship shape survey, comparer the 3-D laser scanner with the present survey systems in all respects to show advantage of 3-D laser scanning technique in rapid and efficient obtainment of the ship 3-D data and extracting ship hull lofting is demonstrated in the experimentation. KEY WORDS: shipbuilding, the model of survey, 3-D laser scanner, requirement analysis, the handle of point cloud data 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc231544363 1 绪论 PAGEREF _Toc231544363 \h 1 HYPERLINK \l _Toc231544364 1.1 引言 PAGEREF _Toc231544364 \h 1 HYPERLINK \l _Toc231544365 1.2 当今世界造船业的发展动向 PAGEREF _Toc231544365 \h 1 HYPERLINK \l _Toc231544366 1.3 我国造船业和世界先进造船业之间的差距 PAGEREF _Toc231544366 \h 2 HYPERLINK \l _Toc231544367 1.4 本课题的来源和课题提出的目的和意义 PAGEREF _Toc231544367 \h 2 HYPERLINK \l _Toc231544368 1.4.1 本课题的来源 PAGEREF _Toc231544368 \h 2 HYPERLINK \l _Toc231544369 1.4.2 本文的目的和意义 PAGEREF _Toc231544369 \h 3 HYPERLINK \l _Toc231544370 1.5 论文组织 PAGEREF _Toc231544370 \h 4 HYPERLINK \l _Toc231544371 2 造船测量系统 PAGEREF _Toc231544371 \h 5 HYPERLINK \l _Toc231544372 2.1 现代造船流程和所需测量工作 PAGEREF _Toc231544372 \h 5 HYPERLINK \l _Toc231544373 2.2 当今世界造船业的测量状况 PAGEREF _Toc23154437
