摘要
针对传统地形图测绘方法中存在的不足,利用倾斜摄影测量技术实现地形图的全要素获取.基于某一地形图工程实例,详细阐述了外业数据获取流程,分别叙述了像控点采集,外业航飞数据采集,内业空三解算与三维模型制作,最后将三维模型获取的地形图进行精度统计.统计结果表明:通过三维模型技术获取的地形图,满足大比例尺测图的要求,充分证明了倾斜摄影测量技术在大比例尺方面的可行性与有效性.
Abstract
In response to the shortcomings existed in traditional topographic mapping methods,oblique photogrammetry technology is used to achieve full feature acquisition of topographic maps.Based on a terrain map engineering example,the process of obtaining field data is elaborated in detail.It separately describes the collection of image control points,data collection for field aviation and flight,calculation of indoor air traffic,and production of 3D models.Finally,the terrain map obtained by the 3D model was subjected to precision point counting.The point counting results showed that the terrain map obtained through the 3D model technology met the requirements of large-scale mapping.This fully demonstrates the feasibility and effectiveness of oblique photogrammetry technology in large-scale applications.
