摘要
在研究国产高分一号卫星数据特点和梯田纹理特征的基础上,以国产高分一号卫星数据为数据源进行傅里叶变换提取梯田影像研究并进行了可行性分析。经过对包含不同地类、不同尺寸区域的提取测试发现,纹理特征不明显的梯田和纹理不均一的非梯田易造成大量漏提和错提,综合分析认为傅里叶变换提取梯田影像算法难以满足工程化生产的需要。
The paper conducted feasibility analysis on the study of terraces extraction images of Fourier transformation by taking domestic hi-resolution GF-1 satellite data as data source based on the characteristic of GF-1 satellite data and texture features of terraces.It found out that the terraces had no obvious texture features and non-terraces with uneven texture were the main influencing factors of accuracy through the tests on different area types and different sizes of area.The comprehensive analysis concludes that the methodology of Fourier transformation terraces extraction images is difficult to meet the needs of engineering production.
