基于ENVI的高分辨率遥感图像在矸石山提取中的应用研究

Research on the Application of High Resolution Remote Sensing Image in Coal Gangue Dump Extraction Based on ENVI

煤矸石堆积已经成为愈来愈严重的环境问题,及时有效地对矸石山信息进行提取,对于矸石山治理及矸石山地质灾害监测具有重要意义。本文以淮南谢一矿矸石山为例,以Quick Bird高分辨率遥感图像为数据源,利用ENVI软件对图像进行去噪处理、增强处理、几何校正,对矸石山进行提取。从精度检测可以看出,基于ENVI从高分辨率遥感图像中提取矸石山的精度较高,可广泛用于矸石山动态监测与研究。

Piled gangue has become an increasingly serious environmental problem. It is of great significance for coal gangue dump governance and geological disaster monitoring to extract coal gangue dump information timely and effectively. By taking Huainan Xieyi coal gangue dump as an example and the Quick Bird high resolution remote sensing image as the data source, this paper takes de-noising processing, enhancement processing and geometric correction on the image by using the ENVI software to extract the coal gangue dump. The results show that coal gangue dump extracted from high resolution remote sensing image based on the ENVI software has a higher precision and this method could be widely used for dynamic monitoring and research on coal gangue dump.
