| 摘 要： | 利用黑龙江省塔河地区2008年的快鸟影像,研究了基于高空间分辨率的卫星影像的单木树高提取方法.在试验区内,实测孤立木的树高、胸径和冠幅,并在遥感图像对应位置上一一标记.在对快鸟影像进行裁剪、几何校正等处理的基础上,提取孤立木树冠顶点区域在遥感图像上的灰度值,然后建立灰度值与其树高之间的回归模型,其决定系数达到0.88,...

| Abstract: | A study was conducted to extract individual tree height using high spatial resolution remote sensing images and the Quickbird images of Tahe area in Heilongjiang Province in 2008.In the experimental area,the height,diameter at breast height(DBH) and crown width of the isolated trees were measured,and these trees were marked respectively on the remote sensing images.Based on the fusion and geometric correction of the Quickbird images,the gray value of the crown peak area of the isolated trees were obtained,a... |
