摘要
三维激光成像系统是一种包含多种先进技术的复杂系统,它包含了数据的采集、简化和处理等过程。三维激光成像系统的主要问题是数据处理,对于三维的点云进行表面建模和构建立体三维的Delaunay三角网这一技术还没成熟,目前没有统一的算法能完全解决这一课题,构建的模型在细节上还不能令人满意。为解决这一问题,提出一种三维激光成像系统新的平面离散数据三角剖分方法。通过实验验证这种方法不仅能够很好地对平面离散数据三角剖分,而且能处理有凹面或洞等复杂表面状况的平面。
The 3D laser imaging system is a complex system which contains a variety of advanced technologies.Its work flow includes the data collection,simplifying and processing.The main problem of this system is the data processing.The technology of the surface modeling of the 3D point cloud and the building of a true 3D Delaunay triangulation has not yet been mature.There is no unified way to solve the subject,as the model is unsatisfactory on details.In order to solve the problem,a new method to triangulate the DEM data of the 3D laser imaging system is proposed in this paper.It is verified by experiments that this method can not only triangulate the DEM data well,but also be able to deal with the complex surface condition with a concave or a hole in the plane.
