一种基于序列影像匹配的独立树冠可视化方法

A Visualization Method to Resconstruct A Unique Crown Based on Sequential Image Matching

介绍采用非量测相机与序列影像匹配实现独立树冠 3维重建的方法。主要包括从影像提取特征点;使用多基线影像与金字塔分层相关技术进行特征点匹配;解算影像的相对方位参数;由前方交会求出各特征点的模型坐标;由模型坐标构造树冠表面三角网;由纹理映射得到树冠 3维模型景观图,实现树木可视化的真 3维表达。

This article puts forward a method to reconstruct 3D tree by the non-measurable camera and sequential images,The procedure includes:extracting feature point from image;matching the homologous point by images of base linews and pyramid technology;solving the model coordinate of every feature point by forward intersection;and constructing the TIN of the tree's figure by the model coordinates;then generateing the 3D model landscape map by texture。
