Abstract
Crown is a key part of tree. It's the main place that photosynthesis has been taken place. It's also the important energy sources that tree need to grow. So, some researchers often study how to monitor growth of tree, predict trees' life increment and judge the quality of wood, and so on by using remote sensing technique. The appearance of commercial high-resolution satellite data supplies new resources for people to study crown structure of a tree by using remote sensing technique. In this paper, method to detecting tree crown by using QuickBird image that covers the demonstration has been studied. Base on image process, Object-Oriented image analysis method has been taken. The tree crown has been effectively extracted from the QuickBird image by using Fuzzy Classification method that bases on samples. At the same time, it can give some experiment to process high spatial resolution satellite image and make a strong base for promoting the application of high-resolution satellite image in forestry and entironment construction of our country.
