라인 레이저 기반 3차원 스캐너에서 투영을 이용한 고속 3D 메쉬 생성

Abstract

ABSTRACT This paper presents a fast 3D mesh generation method using projection for line laser-based 3D scanners. The well-known method for 3D mesh generation utilizes convex hulls for 4D vertices that is converted from the input 3D vertices. This 3D mesh generation for a large set of vertices requires a lot of time. To overcome this problem, the proposed method takes (θ-y) 2D depth map into account. The 2D depth map is a projection version of 3D data with a form of (θ, y, z) which are intermediately acquired by line laser-based 3D scanners. Thus, our 2D-based method is a very fast 3D mesh generation method. To evaluate our method, we conduct experiments with intermediate 3D vertex data from line-laser scanners. Experimental results show that the proposed method is superior to the existing method in terms of mesh generation speed. 키워드 : 2D 깊이지도, 3D 스캐너, 라인레이저 스캐너, 메쉬 생성법 Key word : 2D depth map, 3D scanner, Line laser scanner, Mesh generation Received 23 December 2015, Revised 13 January 2016,
