基于航空摄影方式生产地形图,其精度与航摄影像分辨率呈正相关.在山区地形中,航空摄影方式获得的影像分辨率差异大,导致得到的地形图精度不均匀,易超限.针对这个问题,在深入分析仿地飞行和倾斜摄影测量技术后,提出将两种技术结合,用于山区大比例尺地形图的测绘,并以实际项目为例,对本方案的可行性进行了验证.结果表明:采用本方案生产的山区大比例尺地形图,精度均匀,符合相关规范要求,可以为山区大比例尺地形图的测绘带来借鉴.
Application of Imitation Flight and Oblique Photogrammetry Techniques in Large-scale Topographic Map Surveying and Mapping in Mountainous Areas
The accuracy of topographic map production based on aerial photogrammetry is positively correlated with the resolution of aerial photogrammetry image.In mountainous terrain,image resolution obtained by aerial photogrammetry varies greatly,resulting in uneven topographic map accuracy and easy to exceed the limit.In order to solve this problem,after in-depth analysis of imitation flight and oblique photogrammetry techniques,this paper proposes to combine the two techniques to survey and map large-scale topographic map in mountainous areas,and takes a practical project as an example to verify the feasibility of the scheme in this paper.The results show that the large-scale topographic map of mountainous areas produced by the scheme in this paper has uniform accuracy and meets the requirements of relevant specifications,which can bring reference for the surveying and mapping of large-scale topographic map of mountainous areas.
