Abstract:Terrestrial Laser Scanning (TLS) Technology has been widely used in digital city with the development of 3D\|laser scanner hardware and processing method of points cloud data.Nowadays,there are various kinds of terrestrial laser scanners with their distinctive characteristics which can make users confuse in practical work.Meanwhile,there are still some core problems and key techniques need to be paid much attention,especially in large building digitization and reconstruction.In this paper,two typical kinds of terrestrial laser scanners,pulse based and phase based,are studied and used in points cloud data acquiring and reconstruction experiment of large\|scale building.Key techniques of each step,such as data acquisition,data preprocessing including point cloud registration and noise filter,building modeling including plane segmentation and reconstruction,are analyzed and explored.Solutions are proposed for some existing problems which need to be studied further.
Keywords:Terrestrial Laser Scanning  Points Cloud Registration  Building  3D Digital Model
