Critical overview of image-based 3D modeling

ABSTRACT: In this paper we address the main problems and available solutions for the generation of 3D models from terrestrial images. Close range photogrammetry deals since many years with manual or automatic image measurements for precise 3D modeling. Nowadays 3D scanners are also becoming a standard source for input data in many application areas, but imagebased modeling still remain the most complete, cheap, portable, flexible and widely used approach. After reviewing the different 3D shape techniques for surface reconstruction, we will report the full pipeline for 3D modeling from image data. Some modeling methods are also described and different examples are presented.
