摘要
在铁路公路选线时,一般先用数字摄影测量系统对已知相机文件影像进行摄影测量处理,得到数字地面模型(DTM)和数字线画图(DLG),再进一步完成选线设计过程。时有单位因存在缺少相机文件情况,终止相关研究工作而造成经济损失。以温福铁路影像为原始资料的研究,在未知相机文件影像的情况下,提取了较高质量的选线资料。
When selection of railway and highway route, the camera files and images that are already known are commonly processed using digital photographic surveying system to obtain digital terrain model （DTM） and digital line graph （DLG） and then further complete route design. But there are some circumstances occasionally that research work is terminated due to lack of camera files, causing economical loss. In this paper, through studying the images of Wenzhou-Fuzhou Railway as the original data, with camera files or images unknown, higher quality data for route selection is extracted.
