3D Reconstruction of Fruit Tree Stems Based on Improved Matching Algorithm

Wei Yao, Wenjing Zhang, Guifa Teng

Abstract


Image is an important branch of computer vision, and the foundation of virtual reality and scientific visualization. In this paper, the key technology for 3D reconstruction of fruit trees is studied; stems image extraction, feature matching and 3D point cloud computing algorithm are improved. The segmentation time and effect of four kinds of image extraction are compared, and Quantitative analysis of three image matching algorithms and Acquisition method of three-dimensional coordinate information is done. At last, 3D reconstruction of actual fruit tree stems is carried on, and high accuracy, simple and stability of the proposed algorithm are verified.
