An efficient image-based 3d reconstruction algorithm for plants

Abstract

Image-based 3D reconstruction technique can build the model quickly and easily. In this paper, we propose an efficient imagebased method for plant model reconstruction with modified KLT image matching method. The modification makes the new algorithm search the matching points more accurately and helps users to add matching points manually. We present the method to get 3D information from the matching images. An algorithm to unify different coordinate systems has also been introduced in this paper. Finally we discuss an easy texture-mapping way to the 3D vertex model. Keywords: Image-based modeling, modified KLT image matching method © Springer-Verlag 2004.
