Aiming at shortcomings of the traditional damage assessment model based on pixel-level change detection, this dissertation proposes a new model based on change target features vector analysis.

Consequently, traditional change detection methods whether based on pixel level or based on classification can not produce enough accuracy.

传统的基于像素的变化检测方法和基于分类的变化检测方法均难以获得理想的检测效果。
