基于生长模型的苗期大豆植株三维重建
3-dimensional Reconstruction for Soybean Plant of Seedling Stage Based on Growth Model
摘要
Abstract
In order to realize 3-dimensional model reconstruction of soybean,this paper treats the Yellow No.13 soybean in seedling stage as research object.It takes the advantage of cubic parametric spline curve to fit the outline of the leaf,according to the incremental insertion algorithm of Delaunay to realize the triangular mesh of irregular polygon.In research of texture energy,considering the existing methods for the information representation of texture orientation and scale is insufficient,making use of Gabor filter to extract the texture energy feature and Spatial Pyramid Matching (SPM) algorithm to analyze and render texture,combining L-system and the finite state automaton model to realize the visualization of the soybean.Compared with traditional 3D reconstruction method,experimental results show that this method can effectively describe the relationship between the texture clues and the depth of scene,better to keep the topology structure and contour features of the soybean.关键词
