摘 要：
随着经济社会的快速发展,国家基础建设对基础地理信息的需求量越来越大,需要一种能够在少量人工干预的条件下,经过一系列自动化处理,快速输出包括数字表面模型(DSM)、数字高程模型(DEM)、正射影像(DOM)等产品,并能生成一系列其他中间产品的系统设备。该系统采用多种先进算法,包括原始图像增强、快速自动生成和滤除连接点、自动提取密集DSM、传统几何校正、由DTM自动生成等高线、自动生成镶嵌影像等。通过对系统的多次测试,能够高质量地完成基于POS数据的无地面控制点空三加密、自动DEM匹配、自动DOM生产以及影像地图自动切片等任务。

摘 要：
With the rapid development of economic society,the national basic construction of foundation demand for more and more fundamental geographic information.So a system equipment that in a small amount of intervention conditions and after a series of automatic processing was needed,it could fast output digital surface model(DSM),digital elevation model(DEM),digital orthophoto map(DOM) and so on.The system adopt kinds of advanced algorithm,including the original image enhancement,fast automatic generation and the connection for filtering out,automatic extraction dense DSM,traditional geometric correction,automatical generation by the DTM contours,automatic generating mosaic image etc.many times of tests were done for the system,the task of high quality,base on POS data conditions of no ground control point aerotriangulation,automatic DEM matching,automatic DOM production,and the image map automatic biopsy could be completed.
