Through in-depth research and analysis of the level set theory, we have achieved the military targets on ground detection and extraction in SAR images, with the influence of speckle and the features of vehicles and tanks in high resolution SAR images. 针对高分辨率SAR图像中车辆、坦克等目标的特点和相干斑的影响,深入研究分析了水平集理论和抗噪性较强的Chan-Vese模型,实现了SAR图像中地面军事目标的检测提取。
Dynamic compaction method is a way of reinforcing ground. The research on working properties of dynamic compaction ground and foundation is very important for storage tanks, it can make the design and construction more rational. 强夯是一种加固地基的方法,研究强夯地基上储油罐地基及基础的工作性状,对合理设计与施工有着重要的意义。
