摘要
定量分析气象台站周边的人工建筑面积比例,有助于客观揭示人工环境对观测数据的影响。基于Windows平台,利用梯度增强、高通滤波、二值化、形态学等图像处理方法开发了对卫星遥感图像中人工建筑的识别及其面积比例的计算软件,为气象探测环境研究提供可靠的数据。该软件已经用于处理数百个气象台站不同尺度的卫星遥感图像,软件运行稳定,操作方便,可移植性强,相对于人工统计方式效果良好。介绍了所用图像处理方法的原理及软件实现的流程和功能,总结了参数设置的经验。
To reveal the influence of artificial buildings on observed data effectively,it is of importance to identify the ratio of the building area around a meteorological station.The software was developed in order to identify the building area based on the obtained satellite remote sensing images.The proposed software is developed in the Windows system and can provide reliable data analysis for meteorological researches.Hundreds of satellite remote sensing images are experimented using the proposed software.The results indicate that the proposed software achieves higher precision,reliability and efficiency compared with the manual statistical methods.
