摘要
随着我国经济建设的飞速发展,土地利用/覆被变化(LUCC)日新月异,如何快速、高效地获取变化信息已经成为LUCC研究的核心技术之一。本文以SPOT(Pan波段)影像和TM影像为例,对LUCC自动检测方法进行了探讨,并对光谱特征变异法、假彩色合成法、主成分分析法、图像代数法和波段替代法等方法进行了系统分析与比较。实践证明,在科学的图像处理的基础上,综合应用上述方法,能够高效、准确地自动检测出LUCC信息,具有传统的人工目视解译方法无法比拟的优势。
With the fast development of economic construction, LUCC are changing with each passing day in China, and how to acquire changing information has become one of the key technologies in LUCC research. Taking SPOT-Pan image and TM image as a case study, this paper discussed the methods of automatic detection for LUCC, and spectrum feature changing method, pseudo-color composition method etc. were analyzed and compared systemically. It is proved that the LUCC information can be detected efficiently and accurately by using the above methods and which are superior to the traditional comparing detection method by visual interpretation.
