| 摘 要： | 激光扫描系统获取的数据中包含了大量背景信息,给信息提取和表面重建工作带来严重影响,需要有效滤除。依据空间点与平面的位置关系,提出了针对车载激光扫描点云图像背景信息滤除的有效方法,并以OpenGL为工具,开发了一系列点云数据处理工具,能快速、直观、准确地滤除无用背景信息,完整地保留有用的前景信息,从而为大规模三维场景快速重建提供保障。

| Abstract: | Laser scanning system acquires all kinds of information to be detected, some useless information, commonly called background, is included and influences the extraction of useful information and modeling work and should be removed away.Some methods have been developed and been used to remove away background, but these methods are not competent for complex conditions, especially in rebuilding of large-scale scene.In this paper, the authors propose the idea of "clip planes" and develop a set of interactive tools, with these tools, background can be removed away fleetly, visually and accurately. |
