摘　　要：基于无人机平台的垂直摄影立体测图和倾斜摄影裸眼三维测图是大比例尺地形图测绘的2种主要方法。通过对2种成图方法进行研究和比较,总结了它们各自的优缺点。对于测区中建筑物较少的区域,可采用垂直摄影立体测图方式进行地形图测绘,以提高工作效率;而对于测区中建筑物较多的区域,则采用倾斜摄影裸眼三维测图方式进行地形图测绘,以避免繁琐的房檐改正工作,对于在三维实景模型上一些不易分辨或不方便采集的要素,同时采用垂直摄影立体测图方式进行补充采集,从而减少外业调绘和补测的工作。在西藏自治区桑日县城规划区1:500地形图测绘项目中,综合采用了上述2种方法进行成图,成功地将外业调绘和补测工作量减少了80%以上,降低了劳动强度,显著提高了作业效率和质量。Two main methods for large-scale topographic mapping are vertical aerial photogrammetry and oblique aerial naked-eye 3D mapping based on unmanned aerial vehicle(UAV)platforms.By studying and comparing these two mapping methods,their respective advantages and disadvantages were summarized.For areas with fewer buildings in the surveyed region,the vertical aerial photogrammetry method was utilized to enhance work efficiency in topographic mapping.Conversely,for areas with a higher concentration of buildings,the oblique aerial naked-eye 3D mapping method was adopted to avoid tedious corrections of eaves.In order to capture elements that are difficult to discern or inconvenient to collect in a three-dimensional real scene model,the vertical aerial photogrammetry method was also utilized as a supplementary approach,thus reducing field surveying and supplemental mapping work. In the 1:500 topographic mapping project of the urban planning areain sangri county, Tibet autonomous region, a comprehensive combination of the aforementioned twomethods was successfully employed, resulting in a reduction of over 80% in field surveying and supplementalmapping workload. This approach significantly reduced labor intensity while improving operationalefficiency and quality.
