【摘要】 三维轮廓测量技术是实现反求工程的重要手段,复杂曲面建模技术是反求工程研究的重点内容。研究了激光线扫描测量原理以及“点云”数据类型。针对栅格点数据,提出了一种快速有效的复杂曲面建模技术,并以实例说明“点云”数据平滑处理、特征线提取、曲面分块及曲面构造过程。更多还原

【Abstract】 The 3D profile measuring technology is an important approach,and composite surface modeling is the main content for researching in reverse engineering. The principle of laser scanning system and the types of cloud data are argued. For grid data, a quick and efficacious method for modeling is designed. It includes the cloud data smoothing, the character line extracting, the cloud data segmenting and the surface constructing, which were illustrate by anexample.更多还原
