摘　　要：为了能够直观地展示排土场分布和形态的特点以及将监测设备布置、监测数据与排土场分布有效结合在一起,将遥感数据融入到排土场监测平台中,形成了基于遥感的排土场监测系统平台.为了解决了多幅影像融合时的变形与亮度问题,利用仿射变法的方法将大区域的遥感数据进行配准、融合成一张影像,并通过矿山的坐标系对融合好的影像进行纠正,保证了影像数据与监测布置的坐标系一致;为了解决遥感数据量大引起的无法在网络上快速浏览的问题,重点研究了图像分割的瓦片技术,将大影像分割为256×256的小影像瓦片,基于分割的瓦片数据,利用哈希格网的改进椭球四叉树的方法来建立快速的索引,使得影像浏览、查询的时间大为缩短,进一步利用遥感影像数据与监测设备布置的坐标系一致,将监测设备布置与排土场分布有机地结合在一起,从而可通过监测平台直接查看排土场分布与监测设备的分布,并通过监测设备查询各类型的日常监测数据曲线.遥感影像安全监测平台通过在云南磷化集团的应用,验证理论研究的意义和实际工程应用的价值.To intuitively display the characteristics of the form and dump distribution, which are efficiently associated with the monitoring equipment layout and monitoring data, the mine monitoring system platform based on remote sensing was formed by the method of putting remote sensing data into dump monitoring platform. A large area of remote sensing data were under registration and fused into one image by the method of affine political reform to solve the image fusion＇s problem in distortion and brightness. And the fusion image was modified by using the mine coordinate system to guarantee the consistent coordinate system between the image data and the mine surveying. The tile image segmentation technology, which divided the large image segmentation into 256 ~ 256 little image tiles, was focused to solve the problem of the failure of quick browsing on the network, caused by the large amount of remote sensing data. Hash grid improvement ellipsoid quadtree method, based on the integral tiles data, was used to establish rapid index to shorten greatly the image browsing and query time. Further more, the consistency of coordinate system between remote sensing image data and monitoring equipment layout was used to organically combine monitoring equipment layout with dump distribution, which allows to check dump distribution and the distribution of monitoring equipment directly through the monitoring platform, and to inquire the various types of daily monitoring data curve through the monitoring equipment. Remote sensing image safety monitoring platform is applied by Phosphate Group in Yunnan, which verifies the significance of theoretical study and practical value of engineering applications.
