【摘要】 提出一种将遥感技术应用到线性文化遗产的自动化监测方法,即基于多时相数字正射影像图(digital orthophoto map,DOM),运用多波段差值法以及面向对象分类监测方法,对线性文化遗产(以苏州宝带桥段遗产保护区为例)进行了自动化监测研究。实验结果表明,两种方法均可用于线性文化遗产自动化监测,但面向对象的分类监测法对连续的、大面积的地物变化更有效,多波段差值法对离散的地物变化更加敏感。该研究为我国线性文化遗产自动化监测与保护提供了思路,具有一定的推广价值。更多还原

【Abstract】 In this paper, remote sensing technology is applied to the monitoring of the dynamic changes of cultural heritage. Based on multi-temporal digital orthophoto map(DOM) images, the multi-band difference method and the object-oriented post-classification change detection method are used to monitor the dynamic changes of the Precious Belt Bridge in Suzhou. Experimental results show that both methods can be applied to the dynamic change detection of cultural heritage, and the object-oriented post-classification change detection method is more effective for continuous and large-scale change of ground objects, while multi-band difference method is more sensitive to discrete ground object changes. The research results in this paper can provide ideas for the intelligent monitoring and protection of the cultural heritage in our country, which is have certain promotion value.更多还原
