摘要: 在基于无人机航拍图像的地震灾情分析及快报系统的研究中,需要实现动态信息图示化,这对图像处理提出了特殊需求。为此,对数学形态学中的闭运算进行扩展,提出了扩展闭运算的概念及其形式化定义,设计了扩展闭运算的实现算法,并用VC++6.0实现了算法的软件设计,应用该软件对实际图像进行处理,满足了实际需求。实践表明,提出的扩展闭运算拓展了数学形态学中闭运算的功能,具有一定的理论意义和实用价值。

Abstract: It is necessary to achieve the image of dynamic information in the earthquake emergency analysis and quick report system based on UAV aerial images,and requires special demands to the imagery processing.Therefore,the closing operation in mathematical morphology is extended and the concept of extended closing operation is proposed.Software development for the algorithm is implemented by using VC++6.0.Processing practical image using this software satisfies practical requirement.Performance of the system with practical image demonstrates that the closing operation proposed in this paper extends functions of closing operation of mathematical morphology and is of theoretical and practical significance.
