利用土地利用状态转移分析的变化检测

Change Detection Based on Land-use Status Transition Analysis

辅助数据在遥感影像变化检测中的应用研究目前还不充分,在分析已有变化检测方法的基础上提出了一种基于状态转移分析的面向对象的变化检测方法。该方法通过历史影像辅助数据估计地物土地利用类型的变化趋势,并利用生成的地物类型状态转移矩阵(STM)对变化检测结果进行修正。对不同时期历史影像生成的状态转移矩阵进行误差分析,结果与本文假设前提相符,而不同方法变化检测结果的对比也证明了本文方法的有效性。

An object-oriented change detection approach based on the status transition analysis is proposed.The historical images are used as the auxiliary data to estimate the trends of the land-use change,and the status transition matrix（STM） are used to modify the change detection results.An error analysis is conducted to test the STMs generated by different period auxiliary images,and the result is consistent with the proposed suppositions in the paper.The validity of the proposed approach is illustrated by the comparison with the results of the different change detection methods.
