摘　　要：提出了一种基于立体模型的横断面测量方法。在定测阶段,以Leica DMCIII数字航摄仪获取的数码影像为原始资料,通过航测外业控制测量和内业空中三角测量等摄影测量手段建立测区立体模型;再结合外业相关资料,基于立体模型,通过人工立体采集的方式进行线路断面线采集,完成线路断面的制作。将大量的外业工作转由内业完成,可简化定测工作,完善勘测设计一体化。In this paper, we present a cross section surveying approach based on the stereoscopic model. In the test phase, taking the digital image obtained by Leica DMCIII digital aerial camera as the original data, we used photogrammetric means such as aerial control surveying and aerial triangulation to establish the stereoscopic model. Then, combining with field related data, based on stereoscopic model, we collected the cross section lines by artificial stereoscopic acquisition, and produced the cross sections. Transferring a large number of field works to internal works can simplify the fixed test work and improve the integration of surveying and design.
