摘    要:运用高分辨率数字摄影机,获取采矿地表塌陷区的数字影像像对,利用在现场布设的像控点建立DLT算法模型,计算出描述塌陷区形态的一系列特征点的三维坐标,在地理信息系统(GIS)的支持下,构建矿区地表原始地形DTM(数字地面模型)和塌陷区现状DTM,将两个DTM进行复合分析、计算出塌陷区的具体形态特征参数如形状、深度、体积等,结果表明这一技术是快速可靠的。

关 键 词:矿山  地表塌陷区  数字近景摄影测量监测  系统结构  像控点  直接线性变换算法  误差分析  数字地面模型

Abstract:An integrated digital image acquisition system with high resolution was utilized to acquire digital image pairs on the terrene around the mining subsided area. The three dimensional coordinates of the control points laid out around the subsidence pit were measured precisely, and these data were used to construct DLT (direct linear transformation) algorithm model for terrestrial photogrammetry. With DLT algorithm, the real coordinates of the detail points within the pit on the image pairs were calculated. The DTMs (digital terrain models) of the original terrain before mining and the actuality for the same area were constructed with the support by GIS. While overlaying these two DTMs, the actual subsided parameters of the subsidence pit such as shape, depth, volume can be resolved out. The accuracy analysis result indicates that this monitoring approach is reliable.
Keywords:surface subsidence  digital terrestrial photogrammetry  DLT  DTM
