基于数学形态学的立木树枝信息提取方法

立木树枝信息的提取,是进行立木枝桠遮挡识别的基础。本文提出一种基于数学形态学方法的立木树枝信息提取方法。该方法先利用数学形态学基本运算——腐蚀和膨胀来实现树干信息的提取,然后将枝干的二值图像与提取得到的树干图像做差运算,从而得到树枝信息。实验结果表明,此方法能有效的提取立木图像中树枝的信息。

Extraction Methods of Branches Information of Standing Tree Based on Mathematical Morphology

Extraction of the branches＇ information is the basis of occlusion identification of standing tree branches.An extraction method of the branches＇ information of standing trees was proposed based on mathematical morphology in this paper.Firstly dilation and erosion which are the basic operations of mathematical morphology were used to extract the information of trunk,and then the difference operation of the binary image of standing tree and the image of trunk is introduced to get the branches＇ information.The experiment results showed that the branches＇ information of standing tree can be extracted effectively by using this method.
