Reconstruction of 3D model based on laser scanning

Abstract

Three-dimensional laser scanning can be used to collect spatial location of points rapidly and abundantly, and obtain three-dimensional coordinates of the target surface, which provides new technical means for the rapid creation of three-dimensional image model of the object. Obtaining 3D model from objects is a challenging problem and has been an important research topic in the areas of photogrammetry and computer vision for many years. In this paper, a three-dimensional modelling study on spatial object has been carried out by using the spatial data captured via ground-based 3D laser scanner, and a method of using laser range images for the reconstruction of 3D scene models is proposed. This approach has been described to implement a collection of algorithms for 3D reconstruction, known as image segmentation and range registration based on planar features. After acquisition of range data, images have been segmented to extract planar features and registered to detect the initial configuration between the sensor's coordinate system of two views. Finally, triangular meshes are built to generate a three-dimensional surface model. Through an outdoor experiment of reconstructing a statue, the results of our experiment indicate that the method is accurate and robust. It will be seen that the potential applications is wide, include facilities management for the construction industry and creating reality models to be used in general areas of virtual reality, for example, virtual studios, virtualized reality for content-related applications, social telcpresence, architecture and others.
