基于遥感影像的土地利用变化检测

The Change Detection Based of Land Use on Remote Sensing Image

随着遥感科学技术的发展、各种遥感数据的累加以及遥感变化检测研究的深入,基于遥感影像的土地利用变化检测手段也日新月异。本文主要阐述利用不同的遥感影像处理方法对不同影像之间的土地利用变化进行检测,同时利用影像融合对比法、影像差值法、主成分分析法(PCA法),以及影像分类法等遥感影像处理方法,对同一地区前后不同时相的土地利用变化检测效果进行精度对比,并总结出不同检测方法在不同条件下的检测效果。

With the development of remote sensing science and technology,the accumulation of various remote sensing data and the research of remote sensing change detection,the detection means of land use change based on remote sensing image is also changing with each passing day. In this paper,the land use change between different images is detected by using different remote sensing image processing methods. At the same time,remote sensing images such as image fusion method,image difference method,principal component analysis（ PCA） and image classification are used. Image processing to the same area before and after the different phases of land use change detection accuracy comparison,and summarizes the different detection methods under different conditions of the detection results analysis.
