摘　　要：针对传统方法使用全站仪和RTK检测地形图数学精度效率低的问题,提出利用倾斜摄影构建三维模型对大比例尺地形图数学精度进行检测,并根据地形图质检的特点,设计了飞行航线和像控点布设方案。通过与传统全站仪和RTK作业方法进行比较,分析两种检测方法的外业采样效率以及检验结果的一致性。同时比较两种倾斜摄影相机在获取1.5 cm分辨率的影像时外业作业效率、内业建模耗时和照片数量,分析其各自优劣,为大范围开展地形图数学精度检测提供一种新方案。This article proposes the use of oblique photography to construct a 3Dmodel for detecting the mathematical accuracy of large-scale topographic maps,addressing the low efficiency issue of traditional methods using total stations and RTK.According to the characteristics of topographic map quality inspection,the layout scheme of flight route and image control points is planned.By comparing with the traditional methods,the article analyzes the field sampling efficiency and consistency of the two detection methods.It also compares the field operation efficiency,modeling time,and number of photos required when obtaining images with a resolution of 1.5cm using two types of oblique photography cameras,analyzing their respective advantages and disadvantages.This provides a new solution for conducting mathematical accuracy detection of topographic maps on a large scale.
