基于航模飞行器摄影数据的森林信息提取方法

Method for Extracting Aerial Forest Information from Airplane Aircraft

航模飞行器摄影在很多领域有着越来越广泛的应用,本文利用航模飞行器获取遥感数据,利用PIX4D mapper,Arcgis等软件处理获取拼接影像并提取森林的冠幅信息。以所得影像为基础,通过对森林中树种冠幅-树高和胸径-树高之间关系的研究,利用常用D-H和D-K模型以及摄影测量立体像对的原理,对森林的冠幅、树高、胸径等森林参数信息进行提取,最终反演获得最佳的D-K模型为D=0.933+3.243K-0.57K^2,D-H模型为D=H+0.5610.709。

Aircraft model aircraft photography in many areas has become more and more widely used.In this paper,remote sensing data are acquired by model aircraft,Using PIX4 D mapper,Arcgis to process the collected data obtain the stitching image and extract the crown information of the forest.Based on the resulting image,Accordingstudying the relationship between tree height and tree height and tree height-tree height was studied,Using the commonly used D-H and D-K models As well as the principle of photogrammetric stereoscopic pairing,extracting the crown,height and DBH of the forest,Eventually get best D-K model D=0.933＋3.243K-0.57K^2andbest H-D model D=H＋0.5610.709.
