摘要：用高空间分辨率遥感影像对单木树冠进行自动提取和轮廓描绘是近年来林业遥感领域研究的热点。本文以覆盖实验区的航空影像为例,采用面向对象的多尺度分割方法,逐级对植被对象、树冠对象和分树种模式进行分割,有效地提取了影像中的树冠大小信息。
Automatic extraction and delineation of individual tree crown using high spatial resolution remote sensing has been a hot issue in forest remote sensing research in recent years. In this paper,method to detect tree crown by aerial image that covers the demonstration has been studied. Based on image process,object--oriented image analysis method had been taken. The tree crown had been effectively extracted from the aerial image by multiscale segmentation method that bases on vegetation ob- ject, tree crown object and different tree species respectively.
